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.

{{subst:Add new note/construct|This will work if you do: [[3,3,3],[1,1,1],[5,5,5]] - [[1,1,1] ] //Return: [[3,3,3],[5,5,5]] You have to cover it in extra brackets, because you want to remove the whole element. Not: [[3,3,3],[1,1,1],[5,5,5]] - [1,1,1] //Return: [[3,3,3],[1,1,1],[5,5,5]] But this would work again: [[3,3,3],-1,-1,-1],[5,5,5]] - [1,1,1] //Return: [[3,3,3],[5,5,5]] Note, that all elements found will be removed: [1,2,3,2,4,3,5,2,6,2,7,2] - [2] //Return: [1,3,4,5,6,7]}}
