I'm looking for a way to make object bounce, I've looked at bulletphysics - it seems that Proscenium is using a port of that library - but couldn't find a way to do that in Proscenium. Maybe anyone knows a way to do that?
Set the restitution on both sides. Example:
(sphere.physicsObject as btCollisionObject).restitution = 0.8;
(ground.physicsObject as btCollisionObject).restitution = 0.8;
This will make the sphere bounce against the ground.
