Ok I think I can finally get this to work. I have a tile which is 68pixels wide by 33 pixels tall. A few weeks ago someone or some people had some formulas to check if a point was within isometric tiles. Someone showed a formula for a 48x48 tile and a formula for 32 x 32 tile. Can anyone create a formula for this tile: If not I''m fine with doing it with a ploygon test, but they said a formula would be MUCH quicker. (I appreciate speed. Especially in a games!) Thanks, Ben

There is a very easy way to do this for any isometric tile without the use of formulas and complex mathematical types.

This is done with the use of a mouse map.A mouse map is a bitmap that looks like this:


You just have to determine on which color your mouse is pointing at.If it is white then you are ON the tile.If another color then you are on another tile.
