Bounce

Use this module to make your particles bounce off a surface with realistic physical modeling. This module should have a region connected to it, and that region will act as a bounce plane so that when any particle hits it, it will bounce off at the correct angle.

Layer Properties

Use the Bounce's Layer Properties panel to adjust the effect's parameters.

Trigger: Is an on/off switch using binary code, where 1 = on, while 0 = off.
Friction: Enter a value into this field to increase the amount of friction that each particle experiences as it makes contact with the planar surface. A positive value creates more friction and therefore slows the particle down. A negative value lessens the friction and therefore makes the surface appear more slippery.
Resilience: Changing this value effectively increases or decreases the bounciness of the particle. A value of zero causes the particle to hit the planar surface once and slide off any downward facing angle. A positive value, even by decimal increments, causes the particle to become bouncy. A negative value deadens the effect, the same way a lack of Region would.
Cutoff: Increasing this value widens the bounce arc. If the connected Planar Region is completely flat, a value of zero will cause the particle to bounce up and down in place. A tilted plane in the direction of the bounce will also widen the arc.
