Angle Collisions

This is incredible!  The strategy for making the wall is really interesting.  Lots of stuff I can learn from here.  Thank you.

Thanks,

Yeah the wall building was a bit of a brain teaser. Since I was after a non-trig function, full vector math approach, I had to build in a lot of information for each wall section. The one thing I didn't need was any angle data, just start and end positions, and the rest is derived from those. Even length wasn't strictly necessary, but it maybe saved on a Pythagorean computation or two.

It sometimes folds in on itself in the upper left corner. I was thinking that dropping the "+ rand%" from 'w(x%).s.y = bs% + rand%' might help stop that. Then the upper left starting corner will always be at (100, 100)

The real sleeper was the R2_Norm sub. I was surprised how much of the brute work it did. It even stepped into Bplus' lineSegIntersectCircle function and shortened up the code considerably, given that the infrastructure was already in place. Having that infrastructure in place kept the wall bouncing code fairly short too.

I'm hoping that some of the learning process in doing this will help me on my billiards program, when I can motivate myself to take it back up.
