The restitution coefficient of each particle in the system. Animatable.
Mac Catalyst 13.0+
Restitution determines the amount of energy gained or lost in a collision. (To define collision behavior, see the colliderNodes property.)
A value of 1.0 specifies that a particle loses no energy in a collision (for example, a particle that falls from a certain height onto a flat surface bounces back to the same height). Larger values specify energy gained, and smaller values specify a loss of energy. A value of 0.0 prevents particles from bouncing. You can randomize the bounce factors of particles in the system with the particleBounceVariation property.
