ParticleSystem.emission

Description

Script interface for the EmissionModule of a Particle System.

This module provides control over how many particles are emitted.

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

// Create a Particle System
// At 2 and 4 secs the number of particles are changed to 100, then 200
