Unity3d 如何找到游戲對象並改變其顏色

 

 

//游戲對象
private var obj:GameObject;
//渲染器
private var render:Renderer;
//貼圖
private var texture:Texture;

function Start () 
{
    //獲取游戲對象
    obj = GameObject.Find("Cube");
    //獲取該游戲對象的渲染器
    render = obj.GetComponent("Renderer");
}

 function OnGUI()
 {
     if (GUILayout.Button("Color",GUILayout.Width(100),GUILayout.Height(50)))
     {
         //改變渲染的顏色
         render.material.color = Color.green;
         //添加組件貼圖
         render.material.mainTexture = null;
     }
     
     
     if(GUILayout.Button("add",GUILayout.Width(100),GUILayout.Height(50)))
     {
         
         render.material = null;
         render.material.mainTexture = texture;
     }
 }  

 更改Shader

,如NewShader

Shader "Custom/NewShader" {
    Properties {
        _Color ("Main Color", COLOR) = (1,1,1,1)
        _AmbientColor("Ambient Color",COLOR) =(0,1,0,1)
    }
    SubShader {
        Pass {
            Material {
                Diffuse [_Color]
                Ambient [_AmbientColor]
            }
            Lighting On
        }
    }
}

在代碼中設置顏色

        CubeObj.renderer.material.shader = Shader.Find("Custom/NewShader");     //設置材質的shader
        print(CubeObj.renderer.material.GetColor("_AmbientColor"));  //獲取_AmbientColor 的顏色
        CubeObj.renderer.material.SetColor("_AmbientColor", Color.red);  //設置_AmbientColor的顏色

 

 

 

                //Renderer[] renders = obj.GetComponentsInChildren<Renderer>();

                //foreach (Renderer one in renders)
                //{
                //    one.material.shader = Shader.Find("Custom/NewShader");
                //    Color changeColor = new Color(1,0.33f,1,1);
                //    one.material.SetColor("_IlluminCol", changeColor);  //設置顏色
                //}
