Unity 3d - 渲染的材質選擇

Question

我試圖在運行時更改牆壁的Material。我從Google Sketchup導入房屋模型，它在一個對象中有不同的材質（這在檢查器中顯示）。每當我點擊下一個按鈕（>>），它就會更改對象的第一個材質。我如何獲得對其他元素的引用？這是我到目前爲止有：

public class Material_GUI : MonoBehaviour { 

public Material[] mats; 
public GameObject go; 
private int index = 0; 

// Use this for initialization 
void Start() { 
    go.renderer.material= mats[index]; 
} 

// Update is called once per frame 
void Update() { 
} 

void OnGUI(){ 
    GUILayout.BeginArea(new Rect(Screen.width/2-100,Screen.height-60,200,50)); 
    GUI.Box (new Rect(10,10,190,40),""); 

    GUI.Label(new Rect(62,20,100,20),"Wall Testing"+(index +1)); 

    if(GUI.Button (new Rect(15,15,30,30),"<<")){ 
     index--; 
     if(index<0){ 
      index = mats.Length - 1; 

     } 
     go.renderer.material = mats[index]; 
    } 

    if(GUI.Button (new Rect(165,15,30,30),">>")){ 
     index++; 
     if(index > mats.Length -1){ 
      index = 0; 

     } 
     go.renderer.material = mats[index]; 
    } 
    GUILayout.EndArea(); 
} 
}

如果你想改變渲染器的其他材料，可以使用

go.renderer.materials 

http://docs.unity3d.com/Documentation/ScriptReference/Renderer-materials.html?from=MeshRenderer

例如：

go.renderer.materials[0] = mats[0]; 
go.renderer.materials[1] = mats[1];
