Bounce is a behavior that causes actors to bounce when colliding with solid actors.

Solid needs to be enabled for Bounce to work.


  • Rebound: The amount to bounce. A rebound of 1 means that the object will have the same speed before and after the collision, but in a different direction. Below 1 means the actor will lose some momentum during the bounce. Rebound higher than 1 means the actor will gain momentum, which is not realistic but can be interesting!
