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

using System.Collections;

public class ExampleClass : MonoBehaviour

        ParticleSystem ps = GetComponent<ParticleSystem>();
        var em = ps.emission;
        em.enabled = true;

        em.rateOverTime = 20.0f;

        em.SetBursts(
            new ParticleSystem.Burst[]{
                new ParticleSystem.Burst(2.0f, 100),
                new ParticleSystem.Burst(4.0f, 100)
