ParticleSystem.subEmitters

설명

Script interface for the Particle System Sub Emitters module.

The triggering of the child particle emission is linked to events such as the birth, death and collision of particles in the parent system.

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

using UnityEngine;
using System.Collections;

// A simple example showing access.
public class ExampleClass : MonoBehaviour {

    public ParticleSystem mySubEmitter;

    void Start() {
        ParticleSystem ps = GetComponent<ParticleSystem>();
        var sub = ps.subEmitters;
        sub.enabled = true;
        sub.AddSubEmitter(mySubEmitter, ParticleSystemSubEmitterType.Death, ParticleSystemSubEmitterProperties.InheritNothing);
    }
}

        Material particleMaterial = new Material(Shader.Find("Particles/Standard Unlit"));

        // Create a green Particle System.
        var rootSystemGO = new GameObject("Particle System");
        rootSystemGO.transform.Rotate(-90, 0, 0); // Rotate so the system emits upwards.

        mainModule.startColor = Color.green;
        mainModule.startSize = 0.5f;

        emissionModule.SetBursts(new ParticleSystem.Burst[] { new ParticleSystem.Burst(0.0f, 10) }); // We will emit 10 particles upon death.

        // Set up the sub-emitter.
        subSystemGO.transform.SetParent(rootSystemGO.transform);
