ParticleSystem.emission

Description

Script interface for the Particle System emission module.

The emission 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;

    void Start()

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

        em.type = ParticleSystemEmissionType.Time;

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