将 GameObject 添加到 class 中的列表时出错

Question

我在将 GameObject 添加到 List<> 时遇到问题。当我构建此程序时，poolInstances.Add(clone) 中发生错误：

Error: List.Add(RecyclingGameObject) has some invalid arguments.

错误也出现在 return clone; 行：

Error: Cannot implicitly convert Gameobject to RecyclingGameObject

这是我的代码：

using System.Collections; 
using System.Collections.Generic;  
public class ObjectPool : MonoBehaviour { 

public RecyclingGameObjects prefabs;    

    private List<RecyclingGameObjects> poolInstances = new List<RecyclingGameObjects();  

    private RecyclingGameObjects createInstance(Vector3 pos){   
        var clone = GameObject.Instantiate (prefabs) as GameObject  ;       
        clone.transform.position = pos;         
        clone.transform.parent = transform;  

        poolInstances.Add (clone);      

        return clone; 
    } 
}

Answer 1

替换

var clone = GameObject.Instantiate (prefabs) as GameObject  ;

和

var clone = GameObject.Instantiate (prefabs) as RecyclingGameObjects;

因为您将列表声明为 RecyclingGameObjects，并且 List<RecyclingGameObjects> poolInstances，要添加到列表中的对象类型必须是 RecyclingGameObjects 对象类型，而不是 GameObject。
