Wall

Turns a BuildingType into a wall segment, marks an OverlayType as wall, or lets a WarheadType destroy walls.

Wall structure

Specification — Wall structure
Applies to
BuildingType
File
rules.ini
Section
[<ObjectType ID>]
Value
boolean
When omitted
no

Wall=yes makes a BuildingType a wall segment that never stays on the map as a structure. When it is placed, it puts its ToOverlay overlay in the cell and makes the placing house the cell’s owner. It then reveals the map within its Sight and deletes itself. If the cell refuses the overlay, the placement fails. From structure to overlay covers the cell tests.

Give the type a ToOverlay in its art.ini entry. Without one, placing the structure crashes the game.

A wall segment may be placed next to any cell its house owns, not only next to a building. This lets a wall run extend from the end of an earlier one. Placement decision order covers the full test.

Its build time is multiplied by WallBuildSpeedCoefficient, after every other build-time adjustment. How long it takes lists the steps.

On the sidebar, its cameo sorts into the wall group, with firestorm walls and laser fences.

Wall overlay

[GAWALL]
Wall=yes
Strength=150

Wall=yes makes an overlay a wall segment. The flag turns on:

  • the connection artwork that joins neighboring segments into a run;
  • the damage stages that Strength and DamageLevels drive;
  • blocking, whatever the overlay’s Land value, unless the overlay is also Crushable=yes, which lets crusher vehicles drive over it;
  • the sell cursor and the sale of the segment;
  • damage from a Wall=yes warhead, or from a Wood=yes warhead when the overlay’s armor is wood.

Walls and gates covers each of these. The stock wall overlays leave Land at Clear, so this flag alone makes them block.

Without the flag, an overlay takes no wall damage and has none of the behavior above. It blocks movement only through its land type, as its Land value and the movement costs decide.

This flag is separate from Wall=yes on the BuildingType that lays the overlay. A wall structure converts into the overlay its ToOverlay names whether or not that overlay sets this flag. If the overlay does not set it, the result is an ordinary overlay with none of the wall behavior.

Wall destroyer

Specification — Wall destroyer
Applies to
WarheadType
File
rules.ini
Section
[<ObjectType ID>]
Value
boolean
When omitted
no

An explosion from a Wall=yes warhead can damage the wall overlay in the cell it lands in. The chance of a hit landing depends on the explosion’s raw damage, and Verses does not apply to walls; Taking damage gives the rule. A warhead without the flag leaves walls undamaged, unless it is Wood=yes and the wall’s armor is wood.

In scenarios with DestroyableBridges=yes, the same explosions can damage bridges. Whatever that setting, they crack ice in the explosion’s cell unless they go off up on a bridge.

The flag also affects how objects treat walls:

  • A vehicle that cannot crush a wall in its path treats it as destroyable instead of impassable when its primary weapon’s warhead sets this flag, or is Wood=yes and the wall’s armor is wood.
  • Infantry treat a wall as destroyable only when the primary weapon’s warhead sets this flag. Wood=yes does not count for them.
  • A player-controlled object shows the attack cursor over an enemy wall when the warhead in its first weapon slot sets this flag, or is Wood=yes and the wall’s armor is wood.
  • The computer’s automatic search for walls to shoot skips any object whose primary weapon’s warhead lacks the flag. The difficulty’s DestroyWalls setting can turn that search off.

Walls in combat and movement explains what a vehicle or infantryman does at a wall it reads as destroyable.
