C＃Unity 2D对象池

Question

我目前正在为Unity内的android应用程序工作。在C＃中编写脚本。游戏是一个垂直滚动条，我想要一个无限生成的游戏对象池（在我的情况下是圈子）。我遇到的问题是对象池不会产生，当我可以让它产生在它不回收和重生... 我已经在它几个小时了，我是没有到任何地方。这里是我的代码，我也会链接Unity的屏幕截图。

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine; 

public class CirclePool : MonoBehaviour { 

public GameObject BigCircle; //the circle game object 
public int circlePoolSize = 8; //how many circles to keep on standby 
public float spawnRate = 1f; //how quickly circles spawn 
public float circleMin = 3; //minimum y value of circle pos 
public float circleMax = 7; //max value 


private GameObject[] circles; //collection of pooled circles 
private int currentCircle = 0; //index of the current circle in the collection 

private Vector2 objectPoolPosition = new Vector2(-15, -25); //holding position for unused circles offscreen 
private float spawnXposition = 10f; 

private float timeSinceLastSpawned; 

void Start() { 
    timeSinceLastSpawned = 0f; 

    //initialize the circles collection 
    circles = new GameObject[circlePoolSize]; 
    //loop through collection.. 
    for(int i = 0; i < circlePoolSize; i++) 
    { 
     //and create individual circles 
     circles[i] = (GameObject)Instantiate(BigCircle, objectPoolPosition, Quaternion.identity); 
    } 
} 

void Update() { 
    timeSinceLastSpawned += Time.deltaTime; 
    if (GameController.instance.gameOver == false && timeSinceLastSpawned >= spawnRate) 
    { 
     timeSinceLastSpawned = 0f; 

    //set random y pos for circle 
    float spawnYPosition = Random.Range(circleMin, circleMax); 
    //then set the current circle to that pos 
    circles[currentCircle].transform.position = new Vector2(0, +2); 
    //increase the value of currentCircle. if the new size is too big, back to 0 
    currentCircle++; 
    if (currentCircle >= circlePoolSize) 
    { 
     currentCircle = 0; 
    } 
    } 
} 
} 

FYI：在游戏中的小圆圈是不断向上垂直移动和更大的圆圈会变成某种障碍，但现在我只想把它很好地重生:)。

要添加到CaT对您的文章的评论，您的逻辑看起来是正确的，除了设置转换位置的行外。你没有使用spawnXPosition或spawnYPosition。

尝试修改此：

circles[currentCircle].transform.position = new Vector2(0, +2); 

要这样：

circles[currentCircle].transform.position = new Vector2(spawnXPosition, spawnYPosition); 

这似乎是它会阻止你的重生计时器火灾的唯一其他的事情是，如果GameController.instance.gameOver设置为真正。您可以尝试添加一些调试语句或使用调试器来检查这一点。

Debug.Log("Is the game over? " GameController.instance.gameOver);
