Description
- Description:
- Executes the given command(s) on every item of an array. The array items are represented by _x. The array indices are represented by _forEachIndex. In ArmA2 & VBS2, the variable _x is always local to the forEach block so it is safe to nest them.
- Groups:
- Uncategorised
Syntax
Examples
- Example 1:
{_x setdammage 1} forEach units group player
- Example 2:
- This command can also easily be used to execute a single command multiple times without respect to the array items.
{player addMagazine "M16"} forEach [1,2,3,4]
- Example 3:
- You can also use multiple commands in the same block.
{_x setCaptive true; removeAllWeapons _x; doStop _x;} forEach units group this

- Kronzky
- If arrays are used in forEach loops, _x uses them by reference, so any changes to _x will be applied to the original: _arr1 = [1,2,3]; _arr2 = [6,7,8]; {_x set [1,"x"]} forEach [_arr1,_arr2]; will change _arr1 to [1,"x",3], and _arr2 to [6,"x",8].
