Imagine a game 10x10 tiles. 1024x768 res The hero is on 3,3 and i click with the mouse to 5,7. How can i get the mouse position where the click occurred? Relative mouse axis does not work and absolute is a little bit tricky ... is there a better way to solve the problem ??? BR PerkanusRex

This should work fine:
tile_x = mouse_x/tilewidth;
tile_y = mouse_y/tileheight;

Assuming screen (0,0) is also tile (0,0).
