粒子系统中的任何粒子满足触发模块中的条件时,将调用 OnParticleTrigger。
可用于湮灭或修改碰撞体积内部或外部的粒子。
using UnityEngine; using System.Collections; using System.Collections.Generic;
public class TriggerScript : MonoBehaviour { void OnParticleTrigger() { ParticleSystem ps = GetComponent<ParticleSystem>();
// particles List<ParticleSystem.Particle> enter = new List<ParticleSystem.Particle>(); List<ParticleSystem.Particle> exit = new List<ParticleSystem.Particle>();
// get int numEnter = ps.GetTriggerParticles(ParticleSystemTriggerEventType.Enter, enter); int numExit = ps.GetTriggerParticles(ParticleSystemTriggerEventType.Exit, exit);
// iterate for (int i = 0; i < numEnter; i++) { ParticleSystem.Particle p = enter[i]; p.startColor = new Color32(255, 0, 0, 255); enter[i] = p; } for (int i = 0; i < numExit; i++) { ParticleSystem.Particle p = exit[i]; p.startColor = new Color32(0, 255, 0, 255); exit[i] = p; }
// set ps.SetTriggerParticles(ParticleSystemTriggerEventType.Enter, enter); ps.SetTriggerParticles(ParticleSystemTriggerEventType.Exit, exit); } }
要检索 ParticleSystem 造成的所有碰撞的详细信息,必须使用 ParticlePhysicsExtensions.GetTriggerParticles 检索 Particle 的数组。
