Actions

The parameters in this section define and regulate the various actions that are available to units during a game.

Actions always start and complete (including all of their effects) within the same turn, and a unit can only do one at a time.

All actions are potentially available to all units, but the parameters can be set so as to deny any action type to any unit type. See the descriptions with each action type.

All action is limited by action points. Each unit gets a certain number at the beginning of each turn and expends them in the course of doing things. The usual expenditure is one point per action, but may be more, as defined for each type of action. A unit action must always consume at least one action point. Units can accumulate acp from turn to turn, and they can also reduce acp below zero.

Actions in General

UnitTypeProperty: acp-per-turn acp

This property is the basic allowance of action points that a unit gets each turn.

UnitTypeProperty: acp-min acp

This property specifies how far into "action debt" a unit can go during a turn before it is prevented entirely from acting. A unit with acp < 1 at the beginning of a turn cannot do anything at all.

UnitTypeProperty: acp-max acp

This property is the maximum number of action points that a unit can save up. The value -1 means that acp-max is equal to acp. Extra acp is silently lost. Defaults to -1.

UnitTypeProperty: free-acp acp

This is the amount by which the acp for some action can exceed the difference between the unit's currently available acp and its minimum acp, and still allow that action. By default, no free acp is awarded.

Note that a unit with an acp of 0 and an acp-min of 0 is completely unintelligent, about like a cow patty. Cow patties can be useful for blocking paths, hiding behind, and suchlike, and have the advantage that once they're in place, you don't have to manage them. Other units will have to pick them up and put them down, of course.

TableUM: material-to-act u m -> n

This table is a minimum amount of m needed for u to be able to act. The material is not consumed.

UnitTypeProperty: acp-damage-effect interpolation-list

This property is the effect of a unit's hp on its acp. The input value is hp, while the output value is the acp to be added instead of acp-per-turn. This list does not extrapolate. Defaults to ().

TableUT: night-adds-acp u t -> n

Action points can be added to an unit of type u if it is night at the cell of type t where it is located. Subtraction can be done as a negative addition.
NOTE: Currently applies only to cell terrain subtypes.
NOTE: This can generally be expected to be only applied at the start of a turn.

TableUT: night-multiplies-acp u t -> .01n

Available action points can be multiplied against a factor n if an unit of type u is on a cell with terrain t when it is night. Defaults to 1.00.
NOTE: Currently applies only to cell terrain subtypes.
NOTE: This can generally be expected to be only applied at the start of a turn.

TableUU: occupant-adds-acp u1 u2 -> n

If an occupant of type u2 is in a transport of type u1, then the occupant can confer n action points upon the transport.
NOTE: Presently, the available ACP of an unit is only updated at the beginning of turns. So, available ACP will not immediately change upon entry of the ACP-affecting occupant. This behvaior may change in the near future, so that the effect will be immediate.

TableUU: occupant-multiplies-acp u1 u2 -> .01n

If an occupant of type u2 is in a transport of type u1, then the occupant may have a multiplicative effect on the transport's action points by a factor n. Defaults to 1.00.
NOTE: Presently, the available ACP of an unit is only updated at the beginning of turns. So, available ACP will not immediately change upon entry of the ACP-affecting occupant. This behvaior may change in the near future, so that the effect will be immediate.

UnitTypeProperty: acp-morale-effect interpolation-list

This property is the effect of morale on acp. The input value is morale, and the result value is multiplied with acp, after it has been modified for night effect, but before modification for temperature. The result is divided by 100, so an effect < 100 reduces acp, an effect of 100 has no effect, and an effect > 100 increases acp. Defaults to ().

UnitTypeProperty: acp-per-turn-min acp

This property sets a lower limit on the effect of occupants, damage, and other modifiers on the acp to be added at the beginning of the turn.

UnitTypeProperty: acp-per-turn-max acp

This property sets the upper limit on the effect of occupants and other modifiers to the acp added at the beginning of the turn. Defaults to -1, which indicates that there is no limit.

UnitTypeProperty: acp-independent t/f

This property indicates that the unit's actions are to be limited by materials, rather than by a fixed number of acp each turn.

Action Ordering

GlobalVariable: use-side-priority t/f

This variable is true if the sides may only act one at a time; otherwise, all sides and units may move simultaneously during a turn. Defaults to false. This variable is also set by the sequential variant.

UnitTypeProperty: action-priority n

This property is the order in which units of this type will act. Higher numbers act earlier. If the difference between the priority of one type and another is greater than 100, then the earlier-acting units must finish acting before the later-acting units, otherwise a player can rearrange the actual acting order as desired.

Movement Action

Movement is the most common sort of action. This section covers movement over open terrain; the next section discusses interaction with transports.

The general theory of movement is that a unit not in a transport crosses its current cell terrain to the edge of the cell, crosses any border terrain, and then moves into the destination cell, OR it moves onto connection terrain, travels along connection terrain to the new cell, and maybe moves off the connection. If the unit starts in a transport, then the transport may ferry the unit over some of the intervening terrain, possibly as far as the unit's destination.

A unit's basic movement rate is defined by its speed, which is a ratio of the the unit's acp. A speed of 100% means that the unit can potentially enter as many cells as it has acp, while a speed of 20% means that the unit uses at least 5 acp to enter a cell.

Movement can only succeed if several conditions are met: the unit must be able to cross the border terrain, the destination must be inside the world (but see below), it must be able to exist on the terrain of the destination.

ActionType: move x y z

This is the action that a unit performs to go from its current location to the cell at x,y at altitude z. The destination must be within the move-range of the unit.

UnitTypeProperty: acp-to-move acp

This property is the number of acp a unit uses to do one move action. Defaults to 1.

UnitTypeProperty: speed n

This property is the basic multiplier relating acp to the number of cells that may be entered during a turn. Defaults to 100.

UnitTypeProperty: speed-damage-effect interpolation-list

This property is the unit's speed if it is damaged. The input value is the unit's hp, while the result value is the unit speed to use instead of speed. Defaults to ().

TableUU: occupant-adds-speed u1 u2 -> n%

Each value in this table is the amount of speed that an occupant u2 adds to transport u1.

TableUU: occupant-multiplies-speed u1 u2 -> n%

Each value in this table is the factor an occupant u2 multiplies the accumulated speed (including additive effects) of a transport u1 by. Defaults to 100%.

UnitTypeProperty: speed-wind-effect list

This property is a list that describes the effect of wind on the unit's speed. The effect is calculated using a combination of the cells being left and entered. The format of the list is

((angle-list ) ...)

where angle-list is a single number, list of number, or the symbol all, and the value is either a number, or a list of the form

((force number) (force number) ...)

For hex areas, the angles are 0 for downwind (same direction), 1, 2, and 3 for directly upwind (opposite direction). The force is the wind force in the cell, and number is the multiplier for the speed, with 100 having no effect, numbers less than 100 decreasing the unit's speed, and numbers greater than 100 increasing it. Defaults to ().

UnitTypeProperty: speed-min mp

This property is the worst-case speed of a unit.

UnitTypeProperty: speed-max mp

This property is the upper bound on a unit's movement in one turn. (?)

UnitTypeProperty: move-range n

This property is the maximum distance allowed to the destination cell. Defaults to 1.

The product of a unit's acp and its speed is its available movement points. Any move between cells will cost at least one movement point. Some mp costs may be negative, but the total mp for a move will always be at least 1.

TableUT: mp-to-leave-terrain u t -> mp

This table is the mp cost to leave a cell of type t. If t is a border type, this cost is never used. If t is a connection type, this cost is the cost of leaving the connection terrain for the open terrain of the cell. If t is a coating type, then this value adds to the cost of leaving the cell.

TableUT: mp-to-enter-terrain u t -> mp

This table is the mp cost to enter a cell of type t. If t is a border type, this cost is the cost of crossing the border. If t is a connection type, this cost is the cost of entering the connection terrain from the open terrain of the cell. If t is a coating type, then this value adds to the cost of entering the cell. Defaults to 1.

TableUT: mp-to-traverse u t -> mp

This table gives the cost to travel along a connection or border of the given type. (note that the other costs are irrelevant if unit starts and ends its movement on the connection).

A special type of move known as a border slide can occur when the endpoints of a border touch on the start and destination cells. Sliding works like normal movement that happens to end up on a nonadjacent cell. Same rules for permissibility apply. If the value is negative, then border sliding is not possible.

Defaults to -1.

If both enter/traverse/leave and enter/leave movement is possible, then Xconq will automatically choose the cheapest alternative.

Each unit type has a range of altitudes within which it normally operates.

TableUT: altitude-min u t -> n

This table is the minimum altitude possible for each type of unit on each type of terrain.

TableUT: altitude-max u t -> n

This table is the maximum altitude possible for each type of unit on each type of terrain.

UnitTypeProperty: mp-to-leave-world mp

This property is an additional move cost to leave the world entirely. To leave, the unit must be within its move-range of an edge, and have sufficient mp to move into the terrain in the edge cell designated as the destination of the move. If the value is -1, then the unit may never leave. Defaults to -1.

UnitTypeProperty: free-mp mp

This property is the amount by which the move points can "go into the red" and still allow one more move.

ZOC is exerted only over units out in the open, has no effect on occupants, unless they leave their transport. Occupants can themselves exert a ZOC, if occupant-can-fight is true. ZOC applies to all units on a hostile side.

TableUU: zoc-range u1 u2 -> dist

This table is the maximum distance at which type u1 exerts a ZOC over type u2. A value of 0 means that the unit controls only its own cell, and a value of -1 means that the unit does not exert a ZOC at all. Defaults to 0.

TableUT: zoc-into-terrain u t -> t/f

This table is true if the unit exerts its ZOC into terrain t. Defaults to true.

TableUT: zoc-from-terrain-effect u t -> n

Defaults to 100.

TableUU: mp-to-enter-zoc u1 u2 -> mp

This table specifies extra movement points needed by a unit of type u1 to enter the ZOC of a unit of type u2. -1 prevents entry entirely. Defaults to -1.

TableUU: mp-to-leave-zoc u1 u2 -> mp

This table specifies extra movement points needed by a unit of type u1 to leave the ZOC of a unit of type u2. -1 should prevent departure entirely, but that is not currently implemented; set a large value instead to achieve the same effect. Defaults to 0.

TableUU: mp-to-traverse-zoc u1 u2 -> mp

This table specifies extra movement points needed by a unit of type u1 to move within the ZOC of a unit of type u2. -1 should prevent traversal entirely, but that is not currently implemented; set a large value instead to achieve the same effect. Defaults to 0.

If multiple units exert a ZOC into the same cell, then the mp cost adjustment for all ZOCs is the maximum of the different ZOC costs.

TableUU: mp-to-enter-own u1 u2 -> mp

This table specifies extra movement points needed to enter a unit's own cell, irrespective of ZOC. -1 prevents entry entirely. Defaults to -1.

Units may use up some of their materials when they move. Consumption happens after the move action, and only for successful moves.

TableUM: material-to-move u m -> n

This table is the amount of each material that a unit of type u must have in order to be able to move.

TableUM: consumption-per-move u m -> n

This table is the amount of each material used by a unit to do one move action. The amount taken is independent of terrain. If the unit has less than the required amount of any of these materials, it is immobilized until it gets more (this is tested before each move action; note that this does not affect any other action, including entering and leaving transports).

TableUT: control-range u t -> dist

This table is the distance out to which a unit's entry into a cell changes control of the surrounding terrain. A distance of 0 means that the unit only changes control for its own cell, while a distance of -1 means that the unit does not affect control. Defaults to -1.

At present, the maximum value for this is 0 (in other words, a unit cannot change control in adjacent cells).

Entry Action

Units can be inside other units, and have units inside them, in a tree-like fashion. There is no limit on the depth of the tree, but most occupant-transport relationships have other limits.

ActionType: enter unit

This is the action to enter the given unit.

UnitTypeProperty: acp-to-enter-unit acp

This property is the number of acp a unit uses to do one entry action. Defaults to 1.

TableUU: can-enter-independent u1 u2 -> t/f

This table is true if a unit u1 can enter an independent unit u2. Defaults to false.
NOTE: The ability to enter an independent unit implies a form of trust between the independent unit, u2, and its non-independent occupant, u1. So, for example, u1 can take supplies from u2.

Entering and leaving incur mp costs as does movment, but units with a speed of 0 may enter and leave transports.

TableUU: mp-to-enter-unit u1 u2 -> n

This table is the extra movement points required for u1 to enter the transport u2.

TableUU: mp-to-leave-unit u1 u2 -> n

Similar to entry cost.

TableUU: ferry-on-entry u1 u2 -> ferry-type

TableUU: ferry-on-departure u1 u2 -> ferry-type

This table specifies how much intervening terrain the unit u2 entering or leaving transport u1 will have to cross on its own (and thus incur the terrain's mp costs and limitations). Defaults to over-border.

GlobalConstant: over-nothing

This constant indicates no ferrying, occupant must pay all costs to go to destination cell.

GlobalConstant: over-own

This constant indicates that the transport ferries over terrain of its own cell.

GlobalConstant: over-border

This constant indicates that the transport ferries over any border terrain also.

GlobalConstant: over-all

This constant indicates that the transport ferries to destination cell, effectively putting occupant on middle of cell, on connection terrain if necessary.

Develop Action

Development is an action performed by a unit with the sole effect of increasing its side's tech level. Development cannot be performed by independent units.

ActionType: develop u

This is the action of developing the unit type u. If the action is valid, then the tech level of the side will increase. Unit types with any tech crossover will also have their tech levels adjusted.

UnitTypeProperty: acp-to-develop acp

This property is the number of action points used up by one develop action. Defaults to 0, which disallows development.

TableUU: tech-per-develop u1 u2 -> .01n

This table is the gain in tech level resulting from a develop action, expressed as 1/100 of a level. This value is stochastic.

UnitTypeProperty: tech-per-turn-max tl

This property is a ceiling on the total gain of tech level possible in one turn for each side and this unit type. Defaults to 9999.

TableUM: material-to-develop u m -> n

This table is the amount of each material a unit must have in order to do any development.

Toolup Action

There are several stages in the construction of a unit: tooling up, creation, and completion. Tooling up is where the building unit prepares to build, creation is the step where the new unit comes into existence, and completion is where the new unit is brought up to being operational.

For the player, this is mostly automatic; if tooling must be done first, a user command to build will generate the appropriate actions.

Once the technology has been achieved, a unit that intends to construct other units may need to tool up. This is expressed as tool points or tp. Tool points start at zero, can be increased by tooling actions, and may gradually decline (representing wear and tear on the equipment).

ActionType: toolup u

This is the action of tooling up to build a unit of type u. The result is an increase in the tp for the acting unit.

TableUU: can-toolup-for u1 u2 -> t/f

If true, then an unit of type u1 can toolup to construct an unit of type u2. Defaults to false.

UnitTypeProperty: acp-to-toolup acp

This property gives the number of acp needed to do a toolup action.

TableUM: material-to-toolup u1 m -> n

The amount of a material type m required to be on hand, but not necessarily consumed, by an unit of type u1 tooling up for any construction task.

TableUM: consumption-per-tooledup u2 m -> n

The amount of a material type m that is consumed by one toolup action by the unit doing the tooling up, but based on, u2, the type of unit being tooled up for.

TableUM: consumption-per-tooledup u1 m -> n

The amount of a material type m that is consumed by one toolup action by the unit doing the tooling up, based on its type, u1.

TableUM: consumption-per-tp u1 m -> n

The amount of a material type m that is consumed by 1 TP worth of tooling by the unit doing the tooling up, based on its type, u1.

TableUU: tp-per-toolup u1 u2 -> tp

This table is the number of tp gained by one tooling action.

TableUU: tp-to-build u1 u2 -> tp

This table is the number of toolup points needed before a unit of type u1 can create or build a unit of type u2.

TableUU: tp-max u1 u2 -> tp

This table is the maximum possible tooling.

TableUU: tp-attrition u1 u2 -> tp

This table is the number of .01 tool points automatically lost at the end of each turn.

TableUU: tp-crossover u1 u2 -> n%

This table is the number of tool points for u2 that is guaranteed to exist, expressed as a percentage of the tool points for u1.

For instance, if tp-crossover is 80, and a unit's tool points for u1 is 10 out of a max of 20, and the max for u2 is also 20, then the unit will have tool points for u2 at least 8.

Unit Creation Actions

When a constructing unit is tooled up, the create action creates a unit immediately and puts it in its designated location, whether inside the unit doing the building or somewhere nearby. This new unit, however, is incomplete, representing the keel of the ship or the surveyor's lines for an airstrip. Incomplete units are thus basically skeletons, with some unit characteristics, but unable to move or act in any way. They also cannot have any occupants, unless the occupants are of a type that can complete the unit. Those occupants do not derive any protection or other advantages from occupying the incomplete unit, and they are not affected by the occupant-can-build limitation.

ActionType: create-in u unit

This action creates a new unit of type u occupying the given unit unit. The unit unit must have room for the new unit.

ActionType: create-at u x y z

This action creates a new unit of type u in the open at x,y,z. The cell must have room for this new unit.

TableUU: can-create u1 u2 -> t/f

If an unit of type u1 can create an unit of type u2, then this it true. Defaults to false.

TableUU: create-as-build u1 u2 -> t/f

If you intend for creation to cost and construct at the same rate as building, then set this to true, and look at the build action documentation. Defaults to false.

TableUU: acp-to-create u1 u2 -> acp

This table is the acp used by a unit of type u1 to create a a unit of type u2.

TableUU: create-range u1 u2 -> dist

This table is the maximum distance at which a unit of type u1 can create a unit of type u2.

TableUU: cp-on-creation u1 u2 -> cp

This table is the completeness of a unit of type u2 when created by a unit of type u1. Defaults to 1.

TableUM: material-to-create u1 m -> n

This table is the total amount of a material type m required by a unit of type u1 to create anything. This material is not consumed.

TableUM: consumption-on-creation u2 m -> n

This table is the amount of a material type m consumed to create a unit of type u2.

TableUM: consumption-per-create u1 m -> n

This is the amount of a material type m consumed by an unit of type u1 while creating any other unit. This may be negative, in which case, the creator gains m.

TableUM: takes-from-treasury u m -> t/f

This table is true if a constructing unit of type u can take material m if its own supply is insufficient to meet the consumption-on-creation or consumption-per-build (see below) requirements. It should be noted that, unless the storage capacity for the material is 0, then the amount taken from the treasury is only sufficient to close the deficit between the amount of m an unit of type u has on hand and the amount of m that u can store. If u has a 0 storage capacity for m, then an unlimited amount of m can be used from the treasury.

TableUM: treasury-gain-per-create u m -> n

This is the amount of m gained when u is created. This material is added to the treasury of the side that created u. This is not yet implemented.

TableUM: treasury-loss-per-create u m -> n

This is the amount of m lost when u is created. This material is taken from the treasury of the side that created u. This is not yet implemented.

TableUM: supply-on-creation u m -> n

This table is the amount of supply of each material type m to give a newly created unit of type u. This supply is newly generated, does not come from anywhere else. (Note that players could cheat by creating units, taking their supply, and never completing them.)

TableUU: morale-on-creation u1 u2 -> n

This table is the ratio of morale of a unit of type u2 to the morale of its creator u1, with 100 meaning that the new unit has the same morale as its creator. Defaults to 100.

TableUU: opinions-on-creation u1 u2 -> n

This table is the ratio of the opinions of a unit of type u2 to the opinions of its creator u1, with 100 meaning that the new unit has the same opinions as its creator. Defaults to 100.

Unit Completion Action

Once an incomplete unit has been created, other units can help to complete it.

ActionType: build unit

This action adds to the completeness of unit. If the unit becomes complete, it will be given its initial supply, acp, name, etc.

TableUU: can-build u1 u2 -> t/f

If an unit of type u1 can build upon an unit of type u2, then this it true. Defaults to false.

TableUU: acp-to-build u1 u2 -> acp

This table is the acp used up by one build action by a unit of type u1 when buiding a unit of type u2.

TableUU: cp-per-build u1 u2 -> cp

This table is the amount of completeness of a unit of type u2 added by each build action performed by a unit of type u1. If 0, then u1 cannot contribute to completing u2. Defaults to 1.

TableUM: material-to-build u1 m -> n

This table is the amount of any material type m that u1 must have in order to build anything at all. This material is not consumed.

TableUM: consumption-per-build u1 m -> n

This is the amount of material type m that is consumed by the building unit type u1 while building any unit type. This may be negative, in which case, m will be gained by the builder.

TableUM: consumption-per-built u2 m -> n

This table is the amount of each material type m consumed by the builder performing a single build action on a unit of type u2. This may be negative, in which case, m will be gained by the builder. This is compatible with the unit-consumption-per-cp table.

TableUM: unit-consumption-per-cp u2 m -> n

This table is the amount of each material type m consumed by the builder adding 1 CP to a unit of type u2. This may be negative, in which case, m will be gained by the builder. This is compatible with the consumption-per-built table.

TableUU: build-range u1 u2 -> dist

This table is the maximum distance allowed between a unit of type u1 and the incomplete unit of type u2 it is working on. Defaults to 0, which requires the two units to be in the same cell.

At a given point, incomplete units can make progress towards completion on their own. This is automatic because incomplete units are unable to act, and occurs at a constant specified rate. Automatic completion always occurs, even if other units are doing build actions at the same time. The incomplete unit must have any necessary supplies.

UnitTypeProperty: cp-to-self-build cp

This property is the minimum completeness of the unit necessary before it can work on itself.

UnitTypeProperty: cp-per-self-build cp

This property is the completeness added each turn when a unit works on itself.

TableUM: supply-on-completion u m -> n

This table is the minimum amount of supply of each material type m guaranteed to a newly completed unit of type u. If not already available to the unit, it will be newly generated.

UnitTypeProperty: cp-attrition .01n%

This property is the chance that an incomplete unit will lose cp. If the unit loses all of its cp, it vanishes.

Cancelled build tasks can result in the disbanding of the incomplete unit and recovery of the cp and materials in the unfinished unit.

GlobalVariable: disband-unfinished-units t/f

This variable is true if incomplete units not being worked on are automatically disbanded.

GlobalVariable: salvage-unfinished-cps t/f

This is true if the disbanded incomplete unit returns its completeness points.

UnitProperty: cpstash n

This property records unused completeness points.

TableUU: builder-can-reuse-cp u1 u2 -> t/f

This is true if a builder of type u1 can use its cpstash to add to the completeness of a unit of type u2.

GlobalVariable: salvage-unfinished-materials t/f

This is true if the disbanded incomplete unit returns the materials used while building it.

A creator which creates complete units or a builder which completes an incomplete unit may be absorbed by the completed unit. This kind of behavior is often useful for colonizer games, when one does not wish for the colonizer to continue to be around after it has colonized.

TableUU: constructor-absorbed-by u1 u2 -> t/f

If true, then hp-per-garrison HP are taken out of the constructing unit when it completes an unit. Note that this is not a guarantee that the constructor will vanish; its HP must go to 0 for that to happen. Defaults to false.

An unit may automatically be given occupants upon completion.

TableUU: complete-occs-on-completion u1 u2 -> .01n

The number of complete occupants of type u2 placed inside an unit of type u1 upon its completion. The part to left of the decimal is the guaranteed number, and the part to right is the probability of one additional occ.

TableUU: incomplete-occs-on-completion u1 u2 -> .01n

The number of incomplete occupants of type u2 placed inside an unit of type u1 upon its completion. The part to left of the decimal is the guaranteed number, and the part to right is the probability of one additional occ.

TableUU: alt-complete-occs-on-completion u1 u2 -> n

A supplementary (or alternative) number of complete occupants of type u2 placed inside an unit of type u1 upon its completion. This is a Type 1 dice table. Dice rolls less than 0 are treated as 0. Note that this is a supplementary table, and so is additive with complete-occs-on-completion and not contradictory to it.

TableUU: alt-incomplete-occs-on-completion u1 u2 -> n

A supplementary (or alternative) number of incomplete occupants of type u2 placed inside an unit of type u1 upon its completion. This is a Type 1 dice table. Dice rolls less than 0 are treated as 0. Note that this is a supplementary table, and so is additive with incomplete-occs-on-completion and not contradictory to it.

Repair Action

Units can restore their own and each other's hp by doing repairs. Repair requires a repair action.

ActionType: repair unit

This is the action of repairing the given unit.

TableUU: can-repair u1 u2 -> t/f

True, if an unit of type u1 can repair an unit of type u2. Defaults to false.

TableUU: acp-to-repair u1 u2 -> acp

The number of action points used up by a unit of type u1 doing one repair action on a unit of type u2.

TableUU: hp-per-repair u1 u2 -> .01hp

This table is the hundredths of a hp that a single repair action by a unit of type u1 restores to a unit of type u2. The fraction of this over 100 is added to hp directly, while the < 100 fraction is added probabilistically. (For example, a value of 160, or 1.60, means that 1 hp will be added for each action, and there is a 60% chance for an additional 1 hp to be added as well.)

Materials may be needed and/or consumed during repair.

TableUM: material-to-repair u1 m -> n

This table is the amount of each material type m needed for one repair action.

TableUM: consumption-per-repair u1 m -> n

This table is the amount of each material type m used up by a repair action performed by the repairer unit of type u1.

TableUM: consumption-per-repaired u2 m -> n

This table is the amount of each material type m used up by a repair action performed on the repairee unit of type u2.

The following are not really part of the repair action definition, since they occur automatically, but they share many of the tables above.

TableUU: auto-repair u1 u2 -> .01hp

This table is the amount of repair (in 1/100 hp) that u1 will do on any unit of type u2 within range (auto-repair-range). As with hp-per-repair, the < 1.00 part is average, and > 1.00 is guaranteed. Material requirements and usage are as for repair actions. Defaults to 0, which disallows auto-repair.

TableUU: auto-repair-range u1 u2 -> dist

This table is the distance out to which u1 will auto-repair any damaged u2. A value of 0 requires the two units to be in the same cell, while a value of -1 means that u2 must be either an occupant or transport of u1.

UnitTypeProperty: hp-recovery .01hp

This property is the number of 1/100 hp recovered per turn. Recovery happens automatically at the end of each turn. The amount n / 100 is recovered automatically each turn, while n mod 100 is the percent chance of recovering an additional 1 hit point.

UnitTypeProperty: hp-to-recover hp

This property is the minimum number of hp that the unit must have for hp recovery to work.

Material Production Action

Units can produce materials by explicit action.

ActionType: produce m

This action results in a quantity of material m coming into existence.

TableUM: acp-to-produce u m -> acp

This table is the acp used up by one produce action.

TableUM: material-per-production u m -> n

This table is the amount of material produced by u when acting to produce type m.

TableUM: material-to-produce u m -> n

This table is the amount of each material a unit must have in order to produce any material. This material is not consumed by the production action.

Material Extraction Action

Units can extract materials from the terrain or from nearby units.

ActionType: extract x y m n

This action results in the transfer of a quantity n of material m from the cell at x,y.

TableUM: acp-to-extract u m -> acp

This table is the acp used up by one action to extract material of type m.

TableUM: material-to-extract u m -> acp

This table is the material required to do any extraction actions.

Material Transfer Action

Although most movement of materials between units happens automatically (see backdrop economy description), players can also do it explicitly. Players can both take materials from other units, and give a unit's materials to others.

ActionType: transfer unit m n

This is the action of transferring supply to the given unit unit. The desired amount is n; if m is a valid material type, then only that type will be transferred, otherwise the action will transfer all types of materials possible. The actual transfer amounts may be less than n.

TableUM: acp-to-unload u1 m -> acp

TableUM: acp-to-load u1 m -> acp

These tables are the number of action points used up by one material transfer action from u1 to u2. The amount is independent of the material type being transferred. If either value is 0, then the material cannot be transferred.

TableUM: unload-max u1 m -> n

TableUM: load-max u2 m -> n

These two tables determine how much of material m can be transferred out of a unit of type u1 and into one of type u2 in one transfer action. The actual quantity transferred by the action is the minimum of these two values. A value of 0 disallows manual transfer. Both default to -1, which allows any amount to be transferred.

Side Change Action

ActionType: change-side side

This is the action of changing the unit's side to side. The side can be any allowable side, and the unit may be any unit controlled by the actor's side.

UnitTypeProperty: acp-to-change-side acp

If the value of this property is greater than 0, then this type of unit can be ordered to change to another given side. If the unit is not a type that can act, then the side change happens immediately, instead of as an action, and no acp cost is incurred. The type must also be allowed to be on the new side.

Disband Action

Disbanding is the voluntary and controlled destruction of a unit, performed by the unit itself or another unit. A disbanded unit always vanishes, rather than changing to its wrecked-type.

ActionType: disband unit

This is the action of removing hp from unit. The unit will vanish if all its hit points are gone.

UnitTypeProperty: acp-to-disband acp

If the value of this property is greater than 0, then this is the acp that will be used up to do one disband action. If the unit is not a type that can act, then the disband happens immediately, instead of as an action, and no acp cost is incurred.

UnitTypeProperty: hp-per-disband hp

This table is the number of hp lost in a disband action. Defaults to 0, which disallows disbanding.

A disbanded unit can be scavenged for materials.

TableUM: supply-per-disband u m -> n%

This table is the percentage of the unit's supply that is recovered from a single disband action. If the value is zero, then the unit's supply will not be recovered by the disbanding process, and be lost permanently. If any supply remains when the unit's hp is 0, then that supply will be lost also. Defaults to 100, which means that the entire supply will be recovered on the first disband action.

Note that if an essential supply is 100% recovered before the unit is completely disbanded, then it may die from starvation first. A partly-disbanded unit may still acquire supply from nearby units, via the backdrop economy.

TableUM: recycleable-material u m -> n

This table is the quantity of each type of material that becomes available when a unit is completely disbanded. The materials go to transports, occupants, and nearby units, in that order. Any materials exceeding capacities of these units will be discarded. These materials become available only when the unit vanishes.

Type Change Action

Units may change their type. This can be set up to happen automatically, or only with manual intervention from the player.

ActionType: change-type u

This action changes the type of the actee unit to the type u. Upon changing, the relationships of the unit with the world and with other units will be recalculated; occupants that can no longer stay in the unit will be ejected or disappear. The unit itself may vanish or wreck, if it is in the open on a terrain type that will cause units of the new type to vanish or wreck.

TableUU: can-change-type-to u1 u2 -> t/f

True, if a unit of type u1 is allowed to be change its type to u2. If not allowed, then false. The default is false. Not relevant for automatic change-type actions.

UnitTypeProperty: auto-upgrade-to u

Automatically upgrade a unit to unit type u at the beginning of a turn if the change-type criteria are met for this upgrade. Defaults to nonutype.

TableUU: acp-to-change-type u1 u2 -> acp

This table is the number of acp needed to change a unit of type u1 into a unit of type u2. If the value is 0, then the change is never possible.

TableUU: occupants-to-change-type u1 u2 -> n

The number of occupants of unit type u2 required to change a unit of type u1 into another unit type.

TableUA: advance-to-change-type u a -> t/f

Indicate whether an advance type a is needed by a unit of type u to change type. The default is false.

TableUM: material-to-change-type u m -> n

This is the amount of each material type m required for an unit of type u to change type.

TableUU: cxp-to-change-type u1 u2 -> n

Minimum combat experience for a unit of type u1 to change to unit type u2.

TableUU: size-to-change-type u1 u2 -> n

Minimum size for a unit of type u1 to change to unit type u2.

TableUU: turn-to-change-type u1 u2 -> n

Minimum turn for a unit of type u1 to change to unit type u2.

Combat Actions

Xconq combat is somewhat abstract; the attacking player decides what sort of attack to mount and perhaps when to retreat, but all else happens automatically.

The attacker/defender distinction applies only to a single action.

ActionType: attack unit commit

This action is a direct attack on the given unit, at a commitment level of commit. The unit must be known to the attacking unit's side.

ActionType: overrun x y z commit

This action is a combined attack/capture/move action. The basic theory of an overrun is that the actor will attack, capture, or co-occupy the cell at x,y, elevation z, with a commitment of commit. The exact effects depend on the types and sides of units in the destination.

[The commitment levels are currently ignored.]

TableUU: acp-to-attack u1 u2 -> acp

This table is the number of action points used up by a unit u1 when attacking a unit of type u2. If the value is 0, attack is not allowed. Defaults to 1.

TableUU: acp-to-defend u1 u2 -> acp

This table is the number of action points used up by a unit u1 when defending against an attack by a unit of type u2. If the value is 0, attack is not allowed. Defaults to 1.

TableUU: attack-range-min u1 u2 -> dist

This table is the minimum distance at which a unit can attack another. A value of 0 means that units in the same cell can fight.

TableUU: attack-range u1 u2 -> dist

This table is the maximum distance at which a unit can attack another. A value of 1 means that units in adjacent cells may fight, while a value of 0 means that only units in the same cell may fight. Defaults to 1.

GlobalVariable: combat-model n

This variable specifies the algorithm used for combat resolution.

A value of 0 specifies single attack/counterattack with odds determined by the hit-chance table.

A value of 1 specifies multi-round combat with odds computed from attack and defend strength, combat continuing until a participant is destroyed. Combat model one is not fully described in this document. For further details beyond those here, look at the comments in table.def in the xconq source code, at variables such as occupant-affects-attack, occupant-affects-defense, transport-affects-attack, transport-affects-defense, terrain-affects-attack, terrain-affects-defense, neighbour-affects-attack, and neighbour-affects-defense. Plus of course the source code where the variables are consulted (for example model_1_combat in kernel/combat.c).

One round of combat consists of an attack, a reaction, and a calculation of effects.

The defender's reaction is completely automatic, and occurs as part of the combat round. The defender's side does not get a chance to decide what to do until the next round, although doctrine may constrain the set of reactions.

TableUU: surrender-chance-per-attack u1 u2 -> n%

This table is the chance that u2 will surrender to u1 immediately upon being attacked.

TableUU: withdraw-chance-per-attack u1 u2 -> n%

This table is the chance that u2 will retreat from u1 immediately upon being attacked.

TableUU: acp-for-retreat u1 u2 -> acp

This table is the extra acp that u2 can get in order to make a withdrawal possible.

TableUU: counterattack u1 u2 -> n

This table is the strength of a defender's reaction to an attack. If 0, the defender does not counterattack; if 100, the defender counterattacks at the same level as if it attacked normally. Defaults to 100.

In an overrun action, if all the defending units are destroyed, the attacker has sufficient acp and mp, and the destination is safe to enter, then the attacker can move into the defenders' cell.

Firing is a kind of attack that can take place at a distance, involves no commitment or counterattack, and for which the type of ammo may be selected.

ActionType: fire-at unit m

This is the action of firing at a given unit. If m is a valid material type, then that type will be used as ammo, otherwise all available types will be used together.

ActionType: fire-into x y z m

This is the action of firing into the cell at x,y. If z is a valid altitude, then the fire will be concentrated on units at that elevation. If m is a valid material type, then that type will be used as ammo, otherwise all available types will be used together.

UnitTypeProperty: acp-to-fire acp

If this property is greater than 0, this type may attack by firing.

TableUU: acp-to-be-fired-on u1 u2 -> acp

This table is the acp lost when a unit is being fired upon. Defaults to 1.

UnitTypeProperty: range dist

This property is the maximum distance in cells to which a unit can fire. Defaults to 1.

UnitTypeProperty: range-min dist

This property is the minimum distance in cells to which a unit can fire.

UnitTypeProperty: fire-angle-max n%

This property is the highest angle at which a unit may fire, expressed as a percentage of 45 degrees. The default of 0 means that the unit's fire has a flat trajectory and that the target must be on an unobstructed straight line from the firing unit. For values greater than 0, this angle is used to calculate whether the parabolic trajectory clears all intervening terrain.

Units can be on overwatch. Overwatch is a state where an unit will automatically fire at other units it sees moving.

TableUU: zoo-range u1 u2 n

The maximum range for an unit of type u1 to extend a zone-of-overwatch (ZOO) for units of type u2. If the fire range for u1 is less than n, then that will be used instead. Defaults to -1.

TableUU: zoo-range-min u1 u2 n

The minimum range for an unit of type u1 to extend a ZOO for units of type u2. If the fire range-min for u1 is greater than n, then that will be used instead. Defaults to -1.

TableUU: acp-for-overwatch u1 u2 n

The amount of additional ACP that an unit of type u1 receives in order to perform an overwatch firing against units of type u2.

TableUT: weapon-height u t -> elev

This property is the effective height of a unit's weapons when in the given terrain.

Both attack and fire combat calculate hits and damage in a similar way, although they may use different tables.

TableUU: hit-chance u1 u2 -> n%

This table is the basic chance that a unit of type u1 will actually hit a unit of type u2. If the hit chance is 0, then the unit may never attack a unit of that type.

TableUU: fire-hit-chance u1 u2 -> n%

This table is the basic chance that fire from a unit of type u1 will actually hit a unit of type u2. If the hit chance is 0, then the unit may never fire at a unit of that type. If the value is -1, then the value of this is the same as the value of hit-chance. Defaults to -1.

TableUT: attack-terrain-effect u1 t -> n%

TableUT: defend-terrain-effect u2 t -> n%

TableUT: fire-attack-terrain-effect u1 t -> n%

TableUT: fire-defend-terrain-effect u2 t -> n%

These tables specify the effect of attacker's and defender's respective terrains on hit-chance or fire-hit-chance. These chances are multiplied with the basic hit chance. Default to 100.

TableUU: hit-cxp-effect u1 u2 -> n

This table is the effect of combat experience on hit chance. Its value is interpolated according to actual experience (n is the effect when u1 is at its maximum possible experience), then multiplied with the hit chance. Defaults to 100.

The effectiveness of fire may be less at long ranges. If the range to the target is greater than hit-falloff-range, the chance of hitting it will be reduced by the interpolation between the short-range chance and that chance multiplied by the value of hit-at-max-range-effect. For example, if a unit's range is 4, its hit falloff range is 1, the basic hit chance is 60%, and the max range effect is 50%, then its hit chance at range 2 is 50%, at range 3 is 40%, and at range 4 is 30%.

UnitTypeProperty: hit-falloff-range n

This table is the maximum range at which the effectiveness of combat is not affected by distance. Defaults to PROPHI.

TableUU: hit-at-max-range-effect u1 u2 -> n%

This is the multiplier for the effectiveness of firing at the maximum range possible. Defaults to 100.

TableUU: damage u1 u2 -> hp

The basic amount of damage caused by a successful attack. This is a Type 1 dice table. Dice rolls less than 0 are treated as 0.

TableUU: fire-damage u1 u2 -> hp

The basic amount of damage caused by a successful firing. This is a Type 1 dice table. Dice rolls less than 0 are treated as 0. If the value is set to -1, then it is the same as damage. Defaults to -1.

TableUU: tp-damage u1 u2 -> tp

The amount of damage to a unit's tooling caused by a successful attack. This is a Type 1 dice table. Dice rolls less than 0 are treated as 0.

TableUU: damage-cxp-effect u1 u2 -> n

This table is the effect of combat experience on damage. Its value is interpolated according to actual experience (so that n is the effect when u1 is at its maximum experience), then multiplied with both the dice size and the addend of the damage spec. Defaults to 100.

TableUU: hp-min u1 u2 -> hp

This table is the lowest hp possible for u1 from attacks by u2. Further attacks by u2 are still valid, but can do no further damage.

You can set a unit to use a material as ammo.

TableUM: consumption-per-attack u1 m -> n

Specifies how much a material m will be used as ammunition when a unit u1 is attacking.

TableUM: consumption-per-fire u1 m -> n

Specifies how much a material m will be used as ammunition when a unit u1 is firing.
NOTE: Set this to -1, if you wish to use the consumption-per-attack table for firing.

TableUM: hit-by u2 m -> n

The multiplier on the consumption of material m by a unit u1 when it is attacking or firing upon a unit u2.
NOTE: Normally, one would probably want to set this value to 1, if it is desired that the ammo type m be consumed to hit u2. However, u2 can be made "tougher" by setting this multiplier higher, rather than by adjusting the hit-chance and fire-hit-chance tables.
NOTE: To prevent an ammo m from being consumed when hitting a unit u2 (even if the attacker u1 would normally consume this in an attack or firing) then leave the appropriate hit-by table entry at the default value 0, or reset it to that.

If a unit u1 is firing upon a unit u2, then u1 will use the quantity of ammunition m specified in consumption-per-fire multiplied by the corresponding entry in hit-by, if the result is >= 0. Else, it will use the quantity of m specified in consumption-per-attack multiplied by the corresponding entry in hit-by.

TableUM: material-to-attack u m -> n

This table is a minimum of each material type m that a unit must have to engage in direct attack or to defend against it. This minimum is not necessarily used up in combat, it just needs to be present.

TableUM: material-to-fire u m -> n

This table is a minimum of each material type m that a unit must have to fire. This minimum is not necessarily used up, it just needs to be present.

Transports can protect their occupants, and vice versa.

TableUU: protection u1 u2 -> n%

This table gives the effect of occupants of type u1 on the chance of another unit's attack hitting their transport u2, as well as the effect of the transport u1 on the chance that occupants of type u2 will be hit.

For the transport, this is a multiplier, where 100 has no protection, values less than 100 decrease hit chance, and values greater than 100 increase it. Each occupant will be taken into account when computing transport's protection.

If the transport is the unit being hit, then the value of this table is the probability that an occupant of type u2 will be hit.

Defaults to 100.

A transport's destruction may leave occupants stranded on hex, will do some sort of auto-escape or die if terrain is hostile.

Units stacked together can protect each other.

TableUU: stack-protection u1 u2 -> n%

This table is the effect of units of type u1 on attacks on units of type u2 that are in the same cell. The effect is similar to that described for the protection table. Defaults to 100.

Units may also act to protect every other unit in a cell, whether occupant, transport, or stack.

TableUU: cellwide-protection-for u1 u2 -> n%

This table is the effect of any unit of type u1 in the same cell on attacks against any unit of type u2 in the cell. Defaults to 100.

TableUU: cellwide-protection-against u1 u2 -> n%

This table is the effect of any unit of type u1 on any attack on any unit in the cell by units of type u2, expressed as a percentage multiplier. Defaults to 100.

Several other side-effects of combat may also be defined.

Units can retreat if they are about to be damaged; the retreat attempt is automatic, and will be in a valid direction that is away from the attacker. The retreat attempt will fail if there is no direction that the unit may move, or if has insufficient materials, acp, etc to do the movement. If the attempt is successful, then the unit will not be damaged; otherwise it must take the hit.

TableUU: retreat-chance u1 u2 -> n%

This table is the chance that u2 will attempt to retreat if it is hit by u1.

Units may gain experience as a result of combat.

TableUU: cxp-per-combat u1 u2 -> cxp

This table is the number of combat experience points gained by u1 by surviving a combat round with u2. Both attackers and defenders gain experience equally.

TableUU: cxp-per-destroy u1 u2 -> cxp

This table is the number of combat experience points gained by u1 destroying u2. This is in addition to any cxp gained due to combat.

The sides of the victorious and defeated units may be modified as an outcome of unit destruction.

TableUM: treasury-gain-per-destroy u m -> n

This is the amount of m gained when u is destroyed in combat. This material is added to the treasury of the side that destroyed u.

TableUM: treasury-loss-per-destroyed u m -> n

This is the amount of m lost when u is destroyed in combat. This material is taken from the treasury of the side of u.

Unit morale may change as a result of combat, either positively or negatively.

TableUU: morale-hit u1 u2 -> .01n

This table is the 100ths of morale gained as the result of a unit of type u1 successfully hitting a unit of type u2. The part of the number > 100 is gained always, the part modulo 100 is the probability of gaining 1.

TableUU: morale-hit-by u1 u2 -> .01n

This table is the 100ths of morale lost as the result of a unit of type u1 being hit by a unit of type u2.

In combat model 1, the outcome is determined by relative attack and defense strengths.

UnitTypeProperty: attack n

UnitTypeProperty: defend n

These values represent the relative attack and defense strengths of a unit type.

UnitTypeProperty: encounter-result list

This property specifies other possible outcomes of an attack. The list is an optionally weighted list of the form

( [ weight ] result ... )

Each result has one of the following forms:

(unit type message)
(unit (type side) message)
(vanish nil message)

If the chosen result starts with unit, then the encountered unit changes type to the given type, and if the side is specified (as a side id), then it will change side also.

If the chosen result starts with vanish, then the encountered unit simply vanishes permanently.

At present, this property is only used in model 1 combat, where its results are checked before combat. Defaults to ().

Symbol: vanish

This keyword indicates that the encounter result is for the encountered unit to vanish.

Capture Action

A unit may attempt to capture another unit directly. If successful, the captured unit's side changes to that of the capturing unit.

ActionType: capture unit

This is the action of capturing the given unit.

TableUU: acp-to-capture u1 u2 -> acp

This table is the number of acp used up by a capture action. Defaults to 0, which disallows capture.

TableUU: bridge u1 u2 -> t/f

This table is true if a unit of type u1 can be captured by a unit of type u2 even if u1 is on a type of terrain impassable to the capturing unit. Defaults to false.

UnitProperty: match-transport-side t/f

Whenever an unit's transport changes side, automatically try to match the unit's side to the transport's new side.

TableUU: capture-chance u1 u2 -> n%

This table is the basic chance for u1 to capture u2.

TableUU: independent-capture-chance u1 u2 -> n%

This table is the basic chance for u1 to capture an independent unit of type u2. If the value is -1, then the chance of capture is given by the capture-chance. Defaults to -1.

Normally, the protection, stack-protection, cellwide-protection-for, and cellwide-protection-against tables affect the computed capture chance. However, the use of these protection tables can be prohibited by setting the protection-resists-capture global variable to false.

GlobalVariable: protection-resists-capture t/f

When set to false, this variable ensures that the various combat protection tables are _not_ used when computing the success/failure of a capture attempt. Defaults to true (to maintain legacy behavior of older games).

The following tables can affect capture, whether or not protection-resists-capture is set:

TableUU: occupant-allows-capture-by u1 u2 -> n%

An occupant of type u1 affects the capture chance of its transport by n% when an unit of type u2 is attempting to capture the transport. Set to 0% to disallow the transport's capture by u2 when u1 is present. Defaults to 100%.

TableUU: stack-neighbor-allows-capture-by u1 u2 -> n%

If an unit of type u1 shares the same cell with another unit, then it may affect the capture chance of the other unit when an unit of type u2 is attempting capture of the other unit. This table does not apply to occupants of the other unit. Set to 0% to disallow capture of a neighbor by an unit of type u2 when u1 is present. Defaults to 100%.

TableUU: any-neighbor-allows-capture-by u1 u2 -> n%

If an unit of type u1 shares the same cell with another unit, then it may affect the capture chance of the other unit when an unit of type u2 is attempting capture of the other unit. This applies to any other unit in the cell, including one that may be an occupant. Set to 0% to disallow capture of a neighbor by an unit of type u2 when u1 is present. Defaults to 100%.

TableUU: occupant-allows-capture-of u1 u2 -> n%

An occupant of type u1 can prevent capture of its transport of type u2. Set to 0% to disallow capture of a transport of type u2 when an occupant u1 is in it. Defaults to 100%.

TableUU: stack-neighbor-allows-capture-of u1 u2 -> n%

An unit of type u1 sharing the same cell as an unit of type u2 may affect the capture outcome of the latter. This does not apply to occupants. Set to 0% to disallow capture of u2 when u1 is in the same cell as it. Defaults to 100%.

TableUU: any-neighbor-allows-capture-of u1 u2 -> n%

An unit of type u1 sharing the same cell as an unit of type u2 may affect the capture outcome of the latter. This applies to occupants as well. Set to 0% to disallow capture of u2 when u1 is in the same cell as it. Defaults to 100%.

TableUU: scuttle-chance u1 u2 -> n%

This table is the chance that u1, whose capture by u2 is guaranteed, will destroy itself instead. Scuttling is destructive, so u1 changes to wrecked-type. Occupants of an about-to-be-captured unit will also attempt to scuttle.

TableUU: occupant-escape-chance u1 u2 -> n%

This table is the chance that an occupant u1 will escape during the capture of a unit of type u2. Occupants that do not escape are either captured themselves or destroyed, depending on their type and the capturing unit's side.

TableUU: hp-to-garrison u1 u2 -> n

This table is the number of hp that will be taken from the capturing unit u1 in order to guard a captured u2. If the amount is the unit's full hp, then the unit will vanish and any occupants will be distributed to the captured unit, to open terrain, or will vanish themselves if there is no other option.

TableUU: countercapture u1 u2 -> n

This table defines the defending unit's reaction to the capture attempt. If 0, then the unit does not react to the capture attempt.

Captures can also affect combat experience, but has different effects on the capturing and captured units.

TableUU: cxp-per-capture u1 u2 -> cxp

This table is the number of combat experience points gained by u1 for capturing u2.

UnitTypeProperty: cxp-on-capture-effect n

This property gives the change in a unit's cxp due to being captured, expressed as a multiplier. Defaults to 100.

The treasuries of the sides of the captor and prisoner units may be modified as a result of capture.

TableUM: treasury-gain-per-capture u m -> n

This is the amount of m gained when u is captured in combat. This material is added to the treasury of the side that destroyed u.

TableUM: treasury-loss-per-captured u m -> n

This is the amount of m lost when u is captured in combat. This material is taken from the treasury of the side of u.

Capture of an unit may result in its changing type.

TableUU: changed-type-if-captured u1 u2 -> u3

If an unit of type u1 is captured by an unit of type u2, then it will attempt to change into type u3. Defaults to non-unit, which means that no change of unit type will be attempted.

Capture of a unit may also yield an extra dividend of knowledge, in the form of information known to the other side.

UnitTypeProperty: see-terrain-if-captured n%

If the world's terrain is not already seen, this property is the chance that the capturing side will get all of the terrain view collected by the former side of the captured unit. This does not apply to any unit views, just terrain.

TableUU: see-others-if-captured u1 u2 -> n%

This table is the chance that the capturing side will get a view of a unit of type u2 belonging to the other side. The chance applies to each unit of that type when a unit of type u1 is captured.

Detonation Action

Detonation is an action and/or behavior that causes damage indiscriminately. The action specifies the location of the detonation, which may be in the unit's cell or an adjacent one. A unit that detonates loses hp, changing to its wrecked-type if it loses all of its hp. It also hits every unit within a specified radius. Detonation may also affect terrain within a specified radius.

ActionType: detonate x y z

This action detonates the actee at the given location x,y,z.

UnitTypeProperty: acp-to-detonate acp

This property is the number of action points used by one detonate action. Defaults to 0, which disallows detonation.

UnitTypeProperty: hp-per-detonation hp

This property is the number of hp lost in each detonation.

TableUU: detonation-unit-range u1 u2 -> dist

This table gives the range of effect from detonation of u1. The severity falls off according to the inverse square law extrapolated from the adjacent cell damage. (1/4 severity at range 2, 1/9 at 3, etc.)

TableUU: detonation-damage-at u1 u2 -> hp

The severity of u1's detonation on a unit u2 in the same cell. This is a Type 1 dice table. Dice rolls less than 0 are treated as 0.

TableUU: detonation-damage-adjacent u1 u2 -> hp

The severity of u1's detonation on a unit u2 in an adjacent cell. This is a Type 1 dice table. Dice rolls less than 0 are treated as 0.

TableUT: detonation-terrain-range u t -> dist

This table specifies the maximum distance at which a detonation will affect terrain of type t.

TableUT: detonation-terrain-damage-chance u t -> n%

This is the chance that the detonation will have an effect on the terrain.

TableTT: terrain-damaged-type t1 t2 -> n

Relative chance that terrain of type t1 damaged by a detonation will change into another type t2.

TableUT: blasts-into-ttype u t2 -> t/f

Is the new terrain type, t2, a valid outcome for a detonation of an unit of type u. This is used in conjunction with terrain-damaged-type, and never independently. Defaults to true.

The following tables and properties can be used for units that cannot detonate deliberately by doing a detonate action.

TableUU: detonate-on-hit u1 u2 -> n%

This table is the chance that a hit on u1 by a unit of type u2 will cause it to detonate (once). Noncombat reductions in hp, such as attrition, have no effect.

UnitTypeProperty: detonate-on-death n%

This property is the chance that if this type is about to die from a combat hit, it will detonate first.

UnitTypeProperty: detonate-on-attack n%

This property is the chance that if this type scores a hit (and damages) an enemy unit, it will detonate first.

TableUU: detonate-on-capture u1 u2 -> n%

This table is the chance that a unit of type u1 will detonate if a capture by a unit of type u2 is about to succeed.

TableUU: detonate-on-approach-range u1 u2 -> dist

When a unit of type u2 on a non-trusted [?] side appears at a distance of dist or less, then u1 will detonate. If -1, then unit will not detonate upon approach. Defaults to -1.

TableUT: detonation-accident-chance u t -> n.f%

This table is the chance that the unit will detonate spontaneously. This is checked once/turn, at the beginning of the turn, and also upon each entry to a cell, if moving.

Terrain Alteration Actions

ActionType: alter-terrain x y t

This action changes the type of the cell at x,y to t.

ActionType: add-terrain x y dir t

This action adds a connection or border of type t to the cell at x,y, in direction dir.

ActionType: remove-terrain x y dir t

This action removes a connection or border of type t to the cell at x,y, in direction dir.

TableUT: acp-to-add-terrain u t -> n

TableUT: acp-to-remove-terrain u t -> n

For auxiliary terrain types, these tables are the costs to add or remove. For cell terrain, the costs of removing the old type and adding the new type are added together. If the value is 0, then that type of terrain may not be added or removed. As a special exception, cell terrain may have a cost to remove of 0, so that the sum of add and remove costs can be as low as 1; in that case, a value of -1 disallows removal. Both default to 0.

TableUT: alter-terrain-range u t -> n

This table is the maximum distance at which a unit can alter terrain t. Defaults to 0, which means that the unit can change only the terrain in its own cell.

Note that if see-terrain-always is false, then other sides will not see the terrain change unless they are viewing the altered terrain.

TableUM: material-to-add-terrain u m -> n

This table is the amount of material necessary to perform an add-terrain or alter-terrain action.

TableUM: material-to-remove-terrain u m -> n

This table is the amount of material necessary to perform a remove-terrain action.

TableTM: consumption-per-add-terrain t m -> n

This table is the amount of material m necessary for any unit to add terrain of type t.

TableTM: material-per-remove-terrain t m -> n

This table is the amount of material of type m that becomes available as the result of removing terrain t.
