the toplevel [terrain] tag
the [terrain] tag describes a terrain in WML. Terrains are usually described in the terrain.cfg file
the [terrain] tag has the following keys and subtags
- image an image used for this terrain in the map editor
- symbol_image appears to work the same as image - clarification is needed
- adjacent_image a prefix for adjacent terrain images. they will be postfixed with the orientation of the border to give the image name that will be used for the border terrain
- name the name of the terrain
- char the character used to represent this terrain in maps and scenarios
- aliasof characters representing terrains that this terrain will be an alias of. this is a list of characters, with the + and - signs having special meanigns. the string is read left to right taking the best value. when a minus sign is encountered, it starts taking the worst instead. the plus sign reverts it back to the best
- def_alias like aliasof but overides it for defense calculation only
- mvt_alias like aliasof but overides it for movement calculation only
- unit_height_adjust how much the unit graphic should be moved up or down when on that terrain
- submerge float, between 0 and 1: stems how much of the unit graphic should be submerged by the terrain
- no_overlay whether this terrain should be overwritten by other terrain's borders; 'no_overlay=true' terrains are not overwritten.
- light signed value. this will modified local light level on that hex by that amount for gameplay
- heals if set to true a unit on that terrain will be healed at the start of every turn
- gives_income if set to true, this terrain will give income every turn when flagged as if it were a village
- recruit_onto if set to true, it is possible to recruit or recall on that terrain
