我不斷收到錯誤CS0029

Question

我收到以下錯誤：

CS0029 Cannot implicitly convert type UnityEngine.Renderer[] to System.Collections.Generic.List<UnityEngine.Renderer>

的代碼是：

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

public class AssignShadersToChildren : MonoBehaviour 
{ 
    private new GameObject renderer; 

    public Shader shader; // This should hold the Shader you want to use 

    void Start() 
    { 
     // We create a list that will hold all the renderers(objects) 
     // so we can then assign the shader 
     List<Renderer> renderers = new List<Renderer>(); 
     renderers = GetComponentsInChildren<Renderer>(); 

     // For every Renderer in the list assign the materials shader to the shader 
     foreach (Renderer r in renderers) 
     { 
      r.material.shader = shader; 
     } 
    } 
} 

Answer 1

的錯誤是描述性的。您需要將結果轉換到一個列表：

renderers = GetComponentsInChildren<Renderer>().ToList(); 

或更改局部變量是一個數組：

Renderer[] renderers = GetComponentsInChildren<Renderer>(); 

Answer 2

爲什麼不只是列舉的項目？

void Start() 
{ 
    foreach (Renderer r in GetComponentsInChildren<Renderer>()) 
     r.material.shader = shader; 
} 

這件事是GetComponentsInChildren<Renderer>()應該返回IEnumerable<Renderer>不管它是唯一的事情（數組列表...）

Answer 3

您可以簡單地忽略類型，讓編譯器做的工作！如果您隨後將方法調用的結果分配給`renderer'變量，則不需要創建新列表。

void Start() 
{ 
    var renderers = GetComponentsInChildren<Renderer>(); 
    foreach (Renderer r in renderers) 
    { 
     r.material.shader = shader; 
    } 
}
