CharacterVirtual wall sliding jitter

[emaxx99]

Hello, I've been trying out the virtual character controller and have run into an issue with wall sliding. When sliding against a wall with holes (a StaticCompoundShape of ConvexHullShapes), the player oscillates quite a bit.

My character and extended update settings are the same as in the virtual character example. Tweaking them doesn't seem to help, though if I bring mPredictiveContactDistance down enough (e.g. 0.001), sliding becomes smooth but the player starts getting stuck on everything else.

The predictive contact distance will cause what is know as 'ghost collisions' and that is what you're seeing here. This is part of how the algorithm works and very hard to avoid. I think the effect is exaggerated because you use a box as character volume instead of a capsule. Have you tried with a capsule?

Thanks for the quick response and explanation. I tried it with a capsule shape as well, but it didn't help much. Since this is part of the algorithm, I will look into a different way of handling character movement.

B.t.w. did you have mEnhancedInternalEdgeRemoval set to true?
