@Wisom-: The way you’ve chosen to do it is a good solution if you want to access the indexes of multiple tiles during a single tick, when speed is very important. The downside is that you need to add a new, large array, but that’s not that big of a problem. If you do not need to access the tile parents at certain indexes every tick a simpler solution would be to get all actors of class Tile_Parent and run a ForEachLoop where you check the index of each Tile_Parent until you find the one with the correct index.
