Unity：将粒子系统更改为池

  首先，选择粒子系统预制件/ TNT，然后确保未选中 Play On Awake . 下面的池脚本是专门用来实现它的棘手方法 . 它将创建一个 ParticleSystem 数组，然后重新使用它们 . 请注意 ParticlePool 从 MonoBehaviour 继承 not ，因此请确保直接复制它 .

  using UnityEngine;
  using System.Collections;
  using System;
  
  public class ParticlePool
  {
      int particleAmount;
      ParticleSystem[] NormalParticle;
      ParticleSystem[] TNTParticle;
  
      public ParticlePool(ParticleSystem normalPartPrefab, ParticleSystem tntPartPrefab, int amount = 10)
      {
          particleAmount = amount;
          NormalParticle = new ParticleSystem[particleAmount];
          TNTParticle = new ParticleSystem[particleAmount];
  
          for (int i = 0; i < particleAmount; i++)
          {
              //Instantiate 10 NormalParticle
              NormalParticle[i] = GameObject.Instantiate(normalPartPrefab, new Vector3(0, 0, 0), new Quaternion()) as ParticleSystem;
  
              //Instantiate 10 TNTParticle
              TNTParticle[i] = GameObject.Instantiate(tntPartPrefab, new Vector3(0, 0, 0), new Quaternion()) as ParticleSystem;
          }
      }
  
      //Returns available GameObject
      public ParticleSystem getAvailabeParticle(int particleType)
      {
          ParticleSystem firstObject = null;
  
          //Normal crate
          if (particleType == 0)
          {
              //Get the first GameObject
              firstObject = NormalParticle[0];
              //Move everything Up by one
              shiftUp(0);
          }
  
          //TNT crate
          else if (particleType == 1)
          {
              //Get the first GameObject
              firstObject = TNTParticle[0];
              //Move everything Up by one
              shiftUp(1);
          }
  
          return firstObject;
      }
  
      //Returns How much GameObject in the Array
      public int getAmount()
      {
          return particleAmount;
      }
  
      //Moves the GameObject Up by 1 and moves the first one to the last one
      private void shiftUp(int particleType)
      {
          //Get first GameObject
          ParticleSystem firstObject;
  
          //Normal crate
          if (particleType == 0)
          {
              firstObject = NormalParticle[0];
              //Shift the GameObjects Up by 1
              Array.Copy(NormalParticle, 1, NormalParticle, 0, NormalParticle.Length - 1);
  
              //(First one is left out)Now Put first GameObject to the Last one
              NormalParticle[NormalParticle.Length - 1] = firstObject;
          }
  
          //TNT crate
          else if (particleType == 1)
          {
              firstObject = TNTParticle[0];
              //Shift the GameObjects Up by 1
              Array.Copy(TNTParticle, 1, TNTParticle, 0, TNTParticle.Length - 1);
  
              //(First one is left out)Now Put first GameObject to the Last one
              TNTParticle[TNTParticle.Length - 1] = firstObject;
          }
      }
  }
  

  然后，您的 ParticleHolder 脚本应使用以下代码进行更新 . 而已 . 没有更多的实例化 .

  public class ParticleHolder : MonoBehaviour
  {
  
      public ParticleSystem[] effects;
      ParticlePool particlePool;
  
      void Start()
      {
          // 0 = Normal crate
          // 1 = TNT crate
          particlePool = new ParticlePool(effects[0], effects[1], 5);
      }
  
      public void playParticle(int particleType, Vector3 particlePos)
      {
          ParticleSystem particleToPlay = particlePool.getAvailabeParticle(particleType);
  
          if (particleToPlay != null)
          {
              if (particleToPlay.isPlaying)
                  particleToPlay.Stop();
  
              particleToPlay.transform.position = particlePos;
              particleToPlay.Play();
          }
  
      }
  }
