I\'m trying to create a web app/game that uses a side-on \'isometric\' view and transparent tiles. I can display them ok (but not great) using a PHP formula that just sets each
Since this is a tile based game, maybe you should just determine which tile the user is interacting with by using a simple formula. Use some javascript to determine the coordinates of a click or other action. then do some arithmetic to figure out what tile to act on. Does that make sense?
Otherwise, I agree with bobince. You're approach probably won't work easily.
