This should be a fairly easy question. I'm surprised that I have not found a similar question on the forum after searching thoroughly.
I thought GetTile returned a tile Id based on graph coordinates, but inputting different coordinates returns the same int in many cases, so what is it actually for?
For example. on my 128x128 tile map called tileMap, tileMap.GetTile(2,2,0) returns 7 as does 2,14,0 and 6,14,0. 8,14,0 returns 10.
