[Solved]Perfect 90 Degrees

I am trying to get a perfect and consistent 90 degree bounce angle at any speed...

I have put together two tests to show the issue I am having:

bulletbouncetest.capx

lower speeds remain more accurate for more bounces and the higher the speed the lower the accuracy. Am I doing something wrong? Shouldn't these tests render the same results each time even if they weren't pixel perfect?

Is there another simple way to accomplish this? an example would be great! Thanks!!

If the built in bounce isn't working (it should only work at a perfect 90 if you are moving in a straight line and hitting a 45 degree angled object) then you can test for on collision and then manually set the angle to +/- 90 degrees...

Could you look at the example that I have and add your suggestion to it, I cannot seem to get that to work for me...

Ok, I got something close enough to a solution that I can continue on with my project. It still messes up over speed of 1900, but that is enough of a speed range to work with.

I started rounding the angle of the bullet motion to the nearest 90 degrees and the x/y position to the nearest multiple of 64 and made sure all my objects and origin points were positioned accordingly and voila.

Special thanks to Mipeyon this postfor the rounding formula.

I'm guessing the collision is detected on a tick where the ball is not right at the center of the line. Every collision moves the ball a little further from the center, until the ball breaks free. Your solution is as good a way as I can think of to combat the issue.
