Note that this way of removing elements from an array will not work if those elements are themselves arrays.
 
Example:
 
[[0,0,0],[1,1,1],[2,2,2] ] - [1,1,1]


Will not remove the element [1,1,1] from the first array.


[[Array]]<br>_result = [1,2,2,[[player]],"String"] '''-''' [2,[[player]],[[player]],"String"] ............ _result is [1]
A more practical example:
[ [[getPos]] unit1, [[getPos]] unit2, [[getPos]] unit3] - [[getPos]] unit3


Will not remove the position of unit3 from the first array.

Notes

Note that this way of removing elements from an array will not work if those elements are themselves arrays. Example: [[0,0,0],[1,1,1],[2,2,2] ] - [1,1,1] Will not remove the element [1,1,1] from the first array. A more practical example: [ getPos unit1, getPos unit2, getPos unit3] - getPos unit3 Will not remove the position of unit3 from the first array.
