Colliison detection!

[bwhitman]

We've now got great sprite-sprite and sprite-touchscreen collision detection. Every frame, we emit a list of collisions between sprites, and the special sprite 31 for the touchscreen. Use it in your frame callback like:

for c in tulip.collisions():
    (a,b,x,y) = c # a,b are the two sprites, x and y was where the colliison was first reported 

You can have up to 8 collisions reported per frame. Check out collide on Tulip World (world.download('collide')) for a demo!
