public ParticleSystem.CollisionModule collision ;

説明

Script interface for the Particle System collision module.

The collision module enables particles to collide with a predefined list of planes, or with the 2D and 3D physics worlds.

Particle System modules do not need to be reassigned back to the system; they are interfaces and not independent objects.
