Returning current tile

If I understand your question correctly, then you simply need to do this:

x = TileX * TILE_SIZE;
y = TileY * TILE_SIZE;

Where "TileX" and "TileY" is the tile you need to get (what column and row is it in?), and TILE_SIZE is 64 or whatever. You may have to change a few things around depending on how you draw your map though.

Sorry, I just relised I didn't phrase my question very well. (I had a tad too much to drink over Christmas I think!) What I'd like to know is how to return an npc's tile x or y. Sorry again.

x = npc.x * npc.width / tile.width
y = npc.y * npc.height / tile.height

I think that should work

Thank you all for your responses! :)

I was more interested in getting a npc's x,y position in tiles rather than pixels, but I suppose I'll nead to be able to check what tile an npc is standing on aswell at some point!

I can't really give alot of imformation about my engine, as I don't really have alot of imformation about it myself. I'm a novice programmer under training with my game company at the moment, so I'm not really able to give alot of answers at the moment!

Thanks.

So you have the x and y pos of the unit in pixels, and you need the tile position then? The following should do the trick:

TileX = x / TILE_SIZE;
TileY = y / TILE_SIZE;

That will convert your pixel position to Tile Position. You may have to modify it somewhat to fit your project though.
