Yo, Scirra, I've been trying a number of different ways to go about this with tile maps, but I just can't find an efficient way to check to do it.
Basically, what I want to be able to do is select a tile based on its number in the tilemap object itself. This condition would make making games using tilemaps a lot easier, as many games (such as the Pokemon Engine I'm making now) need to change a tile based on whether the player is touching it or not. And I can't seem to be able to check if the player isn't touching it. I can check if it is touching based on the player's position to tile position, but there is only the option to check if a tile exists at a position, not to test if a position exists at a tile... If that makes sense.
What I'm asking is the option to do the opposite, for proper checking of individual tiles contacting another object.
And I didn't know where else to post this, so I'm posting it in open topic.
