Executes the given command(s) on every item of an Array in reversed order, compared to forEach.
Program FlowArrays


code forEachReversed array
code: Code to execute on each array item - available variables:
array: Array - The array to iterate over
Return Value:
Anything - Will return the value of last executed statement


Example 1:
This command lets you easily iterate through an array from last to first element without modifying the array itself with reverse or using for loop with negative step.
// Will show numbers from 5 to 1 in the chat { systemChat str _x } forEachReversed [1,2,3,4,5];
Example 2:
Can be useful to walk through array while also deleting items from it, which you couldn't do with forEach as easily:
private _array = [1,1,2,2,1,1,2,2]; { if (_x == 2) then { _array deleteAt _forEachIndex }; } forEachReversed _array; // _array will be [1,1,1,1] here
Won't work with forEach as you might expect it:
private _array = [1,1,2,2,1,1,2,2]; { if (_x == 2) then { _array deleteAt _forEachIndex }; } forEach _array; // _array will be [1,1,2,1,1,2] here
Example 3:
Deleting items from array with more complex condition than just comparison.
{ if (!alive _x) then { _vehicles deleteAt _forEachIndex }; } forEachReversed _vehicles;
