GDL forms in this section are those that do not really fit anywhere else.
The exact style of display depends on the user interface and on user preferences, but for some games, you may want to encourage a particular style by making it be the default.
GlobalVariable: unseen-char str
This variable is a string whose first character will be used to
represent unexplored terrain. If the string consists of two characters,
the second char will be scattered throughout a field of the first char.
Defaults to " ?". (At present, this is used only by the curses
interface.)
GlobalVariable: unseen-color str
This variable is the name of a color that will be used to represent
unexplored terrain. Defaults to "black".
GlobalVariable: grid-color str
This variable is the name of a color to use to draw the cell-separating
grid. Defaults to "dark-gray".
GlobalVariable: unit-name-color str
This variable is the name of a color to use when drawing unit names and
numbers. Defaults to "white".
GlobalVariable: unit-gbox-border-color str
This is the color to use around the border of a transport's grouping box.
Defaults to "black".
GlobalVariable: unit-gbox-fill-color str
This is the color to use inside a transport's grouping box.
Defaults to "white".
UnitTypeProperty: construction-border-color str
This is the color that frames an unit during its construction.
Defaults to "SandyBrown".
UnitTypeProperty: construction-fill-color str
This is the color that is shown behind an unit during its construction.
Defaults to "brown".
GlobalVariable: contour-color str
This variable is the name of a color to use to draw the elevation
contour lines. Defaults to "saddle-brown".
GlobalVariable: meridian-color str
This variable is the name of a color to use to draw meridians of
latitude and longitude. Defaults to "black".
GlobalVariable: frontline-color str
This variable is the name of a color to use to draw country borders
against other countries. Defaults to "red".
GlobalVariable: country-border-color str
This variable is the name of a color to use to draw country borders
against unpopulated areas. Defaults to "pink".
GlobalVariable: shoreline-color str
This variable is the name of a color to use to draw shorelines (liquid
adjacent to non-liquid terrain). Defaults to "blue".
TableTT: drawable-terrain t1 t2 -> t/f
This table is true when terrain of type t1 should be drawn over
terrain of t2. In practice, you would set this to false to
suppress the drawing of terrain that extends into an inappropriate
types, such as river connections protuding into lakes or seas. Defaults
to true.
MaterialTypeProperty: resource-icon n
This is a value between 1 and 4 that indicates that a material type is to be drawn in each cell indicating that an advanced unit is producing material in that cell. The value is used by the Mac interface to select one of several icons.
It is useful to be able to restart the random number generator consistently.
GlobalVariable: random-state n
This variable is the state of the random number generator. If this is not used, then the initial state of the random number generator will be set in a system-dependent way.
Form: print value
This form prints to a console or file (depending on the interface) the object value, in GDL syntax.
