Alas FF lags a bit at updating the BMP image though. To optimize things a little, you could precompute the BMP header, get rid of the muls by 256 and [i]Math.floor[/i] in the floocasting, and remove the multiple calls to [i]pack()[/i] in favor of a single call when setting the [i]FLOOR.src[/i]. Also, setting the whole [i]style[/i] property instead of multiple sub properties might be faster. Nice work. Oh, btw, I've done raycasting with objects using Canvas, and the depth sorting is trivial. The overhead is negligeable . Moreover IMO it's largely made up for by the equal quality of rendering of all the elements of the game ( walls, sprites, floor & ceiling if any, HUD and other overlays ) : no sharp elements on top of blurred ones or the other way around. And Canvas also makes the management of multiple textures a million times cleaner than the DHTML approach.
