In my little RPG engine-like thing that no one tested, *wink wink*, I tried implementing solid tiles. My algorithm doesn't work, and I don't know why.
I didn't want to put all that in... what I basically wanted to point out was that I was getting the tile number the exact same way I did when I was drawing the map. Yet I usually get a completely different tile to the one the player is walking into. Can anybody help me out here?
