統一：將粒子系統更改爲合併

Question

我試圖將我的粒子系統函數更改爲合併，而不是每次都實例化。我想重複使用這些粒子。這怎麼可能？我不知道如何開始，雖然我看到了統一教程，但不知何故目前還不清楚。也許是因爲即時通訊在其他類中調用粒子系統函數會讓我感到困惑。所有的

public ParticleSystem[] Myeffects; 


public void Particle(int particleNum, Vector3 Pos) 
{ 
    if (Myeffects != null && Myeffects[particleNumber] != null) 
    { 
     if (Myeffects[particleNumber].isPlaying) 
      Myeffects[particleNumber].Stop(); 

     ParticleSystem temp = Instantiate(Myeffects[particleNum], particlePos, new Quaternion()) as ParticleSystem; 

     temp.Play(); 
    } 
} 
} 

Answer 1

首先，選擇您粒子系統預製/ TNT然後確保玩清醒沒有被選中。下面的彙集腳本專門用來實現這一點。它將創建一個指定的ParticleSystem數組然後重新使用它們。請注意，ParticlePool確實是不是繼承自MonoBehaviour，所以請確保直接複製它。

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; 
     } 
    } 
} 

然後，您的ParticleHolder腳本應更新下面的代碼。而已。沒有更多的實例。

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(); 
     } 

    } 
}
