I’m trying to figure out from Flash mouse x,y coordinates what isometric tile I’m in. My tiles are 80x40. I’ve looked at a lot of the tutorials online and explanations and code in forums, but they don’t seem to work with how I’ve got my tiles laid out.

I’ve attached a small image showing how they are laid out, any ideas appreciated.
