Sets wall values at specified coordinates. The amount must be in the range of 0 to 1 where 0 means no wall, and 1 means a full health wall.

Create a rectangle of permanent walls that can't ever be destroyed by Creeper, by repairing them every 9 seconds.

This example will create a square of walls, with the first corner being at X1,Y1(32,32) and the second corner at X2,Y2(64, 64). As these values are Input Variables, you can change them in the editor.

$wallX1:32
$wallY1:32
$wallX2:64
$wallY2:64

GetTimer0 eq0 if
	270 SetTimer0

	<-wallY2 <-wallY1 do
		<-wallX2 <-wallX1 do
			I J 1 SetWall
		loop
	loop
endif

Spawn walls under this unit based on its cell width and cell height. Repair these walls every 9 seconds, effectively making them Crazonium (invincible) walls.

GetTimer0 eq0 if
	270 SetTimer0

	CurrentX ->x
	CurrentY ->y

	Self CONST_CELLWIDTH GetUnitAttribute ->cellWidth
	Self CONST_CELLHEIGHT GetUnitAttribute ->cellHeight

	<-cellWidth 2 div ->cellWidthRadius
	<-cellHeight 2 div ->cellHeightRadius

	<-y <-cellHeightRadius add 1 add <-y <-cellHeightRadius sub do
		<-x <-cellWidthRadius add 1 add <-x <-cellWidthRadius sub do
			I J 1 SetWall
		loop
	loop
endif
