Box collision detection and bouncing

Question

I\'m making pong, and am finding it really difficult to write an algorithm that bounces the ball off the four walls properly (I will deal with scoring later on, because only par

Answer 1

Thanks @jbx, I knew there was a simpler way :) However, that doesn't seem to work for the east and west walls and the paddles (if they're on those walls). This seems to work for me on the east and west walls though:

(180 - (angle + 90)) - 90.

which simplifies to just (180-angle). Hope that helps.
