Hi there,

I wonder if anyone can tell me a method for implementing collision without using sprites for each tile.

I have drawn my map with copypixels, meaning I now need to specify which areas of my map are collidable or not. I am trying to make the game as efficient as possible, so creating a sprite for each tile and running a hitTest strikes me as really sluggish and I am sure there must be a better solution?

Cheers.
