Re: Discontinuous reflection angles for sphere-sphere collisions

This seems to have cleared things up for us! I was experimenting with substepDuration, but not to the extent necessary and not while simultaneously updating maxSubsteps. It seems quite obvious in retrospect. Thank you very much for your help! Come say hello on discord.gg/roundguard if you'd like a b...

Re: Discontinuous reflection angles for sphere-sphere collisions

Thank you for the quick reply! It seems you may be on to something. I did some tests with various launch impulses at zero gravity, and the problem is definitely diminished at lower speeds. With an initial impulse of 50, the response is good enough to be considered smooth: http://wonderbellygames.com...

Discontinuous reflection angles for sphere-sphere collisions

Hello, first-time poster here, be gentle. :) For context, I'm working on a pachinko-style game in Unity using BulletSharp, a C# wrapper around libulletc. A sphere is launched from the top of the screen and bounces off other spheres placed throughout the level, all constrained to a 2D plane. I'm usin...
