Okay. I'm making a breakout game in blitz3d, it's a standard top down one, meaning that the Z-axis has no bearing on ball physics. I posted in the beginner forums and was told to use Normals for the physics to check for the angle and such when rebounding off a surface. It's just I have no clue how this works and looking through the tutorials included with blitz3d and one of the sample programs, but I haven't been able to recreate it. Heres the code that I have so far.
this gives me a memory allocation error. Egh. I've been messing with it for about two hours now and no dice. Also I was wondering if anyone knows of a post or link that explains normal collision detecting in detail.
