Collision¶
Overview¶
Specify parameters for collision. Enabling collision causes particles that collide with the specified surface to bounce back.

Parameters¶
enable¶
Enables collision.
Collide With Ground¶
Enables collision against the ground plane.
External Collision¶
Enables collision against externally provided collision shapes.
Bounce¶
Sets the strength of the rebound upon collision.
Friction¶
Sets the amount of slowdown when a collision occurs.
Height¶
Sets the height of the colliding plane.
Lifetime Reduction¶
Specifies how much lifetime is reduced on collision.
Coordinate System¶
Sets the coordinate system of the colliding plane (local/world).
