当障碍物与边界碰撞时，如何对障碍物进行编码以返回到我的对象池中

Question

请不要被我的长问题吓倒，我确信我只是措辞怪异，哈哈。我遵循了Mike Geig关于在Unity中使用对象池的优秀教程，我很好地理解了这个概念。我只是有一个问题，这个问题让我头疼了近一周。当这个障碍物与南墙（标记为"南墙"）碰撞时，我如何让它回到我的对象池中？我有一张照片和我的脚本：alt text

（下面的脚本是我的通用Pooler脚本，我只是从对象池教程中稍微修改了一下）

     using UnityEngine;
     using System.Collections;
     using System.Collections.Generic;
     public class PoolerTestScript : MonoBehaviour
     {
         public static PoolerTestScript current;
         public GameObject spikeWall;
         public int wallPooledAmount = 20;
         public bool willGrow = true; // This will be false in the inspector and the game, but here I will keep it true so I dont mess anything up.
         private List<GameObject> wallPooledObjects;
         void Awake () 
         {
             current = this;
         }
         void Start ()
         {
             wallPooledObjects = new List<GameObject>();
             for(int i = 0; i < wallPooledAmount; i++)
             {
                 GameObject obj = (GameObject)Instantiate(spikeWall);
                 obj.SetActive(false);
                 wallPooledObjects.Add(obj);
             }
         }
         public GameObject GetPooledObject()
         {
             for(int i = 0; i< wallPooledObjects.Count; i++)
             {
                 if(!wallPooledObjects[i].activeInHierarchy)
                 {
                     return wallPooledObjects[i];
                 }
             }
              if (willGrow)
             {
                 GameObject obj = (GameObject)Instantiate(spikeWall);
                 wallPooledObjects.Add(obj);
                 return obj;
             }
             return null;
         }
     }

（下面的脚本是产生障碍的原因，我从太空射击教程中得到了它，并对它进行了一些修改！）

using UnityEngine;
 using System.Collections;
 [System.Serializable]
 public class Obstacle2 // Spike Wall Obstacle
 {
     public GameObject wall; // The second obstacle gameobject. This is attached in the inspector.
     public Vector3 spawnWPosValues; // Position where the second obstacle will be spawned at on the X,Y,Z plane. 
     public int wCount; // This is the count of the second obstacle in a given wave.
     public float wSpawnWait; // Time in seconds between next wave of obstacle 2.
     public float wStartGameWait; // Time in seconds between when the game starts and when the second obstacle start spawning.
     public float wWaveSpawnWait; // Time in seconds between waves when the next wave of obstacle 2 will spawn.
 }
 public class SpawnWalls : MonoBehaviour {
     public Obstacle2 obstacle2;
     void Start () {
         StartCoroutine (SpawnWall ());
         //InvokeRepeating ("Spawn", 1, 1);
         //Get reference to rigidbody, and set the speed
     }

     IEnumerator SpawnWall () {
         yield return new WaitForSeconds(obstacle2.wStartGameWait);
         while (true)
         {
             for (int i = 0; i < obstacle2.wCount; i++) {
                 Vector3 spawnPosition_2 = new Vector3 (Random.Range(-obstacle2.spawnWPosValues.x, obstacle2.spawnWPosValues.x), 
                                                        obstacle2.spawnWPosValues.y, 
                                                        obstacle2.spawnWPosValues.z);
                 Quaternion spawnRotation_2 = Quaternion.Euler(0,270,0); // was 90, 0, 90 
                 Instantiate (obstacle2.wall, spawnPosition_2, spawnRotation_2);
                 yield return new WaitForSeconds(obstacle2.wSpawnWait);
             }
             yield return new WaitForSeconds (obstacle2.wWaveSpawnWait);
         }
     }
 }

（下面的脚本是移动障碍的东西）

 using UnityEngine;
 using System.Collections;
 public class WallObstacleMover : MonoBehaviour {
     private Rigidbody rb;      //Reference to Rigidbody Component
     public float speed;        //Speed, updated through script
     public float acceleration; //Every second, the speed will increase by this much
     //Executes once, when object is spawned / scene loaded
     void Start() {
         //Get reference to rigidbody, and set the speed
         rb = GetComponent<Rigidbody> ();
         rb.velocity = -transform.right * speed;
 }
     //Executes every frame
     void Update() {
         //Add acceleration to speed, make sure it's not above topSpeed)
         speed += Time.deltaTime * acceleration;
         //Set object velocity
         rb.velocity = -transform.right * speed;
     }
 }

您不使用pooler来实例化障碍，只需在协同程序中实例化它。您需要使用PoolerTestScript中的GetPooledObject（）来汇集障碍。然后在冲突时，您不需要破坏游戏对象，而是调用一些您还需要创建的GoBackToPool（）方法（并且池对象需要一种方法来找到它所属的池，所以要么保留引用，要么进行一些提供静态访问的场景管理-委托将是另一种选择）
