unity3d鼠标经过物体时变颜色，离开时恢复

using UnityEngine;
using System.Collections;

public class MouseEvent_Color : MonoBehaviour {

    //物体初始颜色
    private Color CubeColor;

    private Texture CubeTexture;

    private GameObject ObjCube;

	// Use this for initialization
	void Start () {

        ObjCube = GameObject.Find("Cube");
        ObjCube.renderer.material.shader = Shader.Find("Diffuse");
        CubeColor = ObjCube.renderer.material.GetColor("_Color");
        Debug.LogError("材质球颜色："+CubeColor);

        CubeTexture = renderer.material.GetTexture("Cube");

	}

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

	}

    /// <summary>
    /// 鼠标经过
    /// </summary>

    //void OnMouseOver()
    //{

    //    // cubeobj.renderer.material.color = Color.red;
    //    renderer.material.color = Color.red;

    //}

    /// <summary>
    /// 鼠标进入
    /// </summary>
    void OnMouseEnter()
    {

        renderer.material.color = Color.red;

    }

    //鼠标离开

    void OnMouseExit()
    {
       // renderer.material.SetTexture("Cube",CubeTexture);
        renderer.material.color = CubeColor;

    }
}

　　Shader：材质球-点击“Edit”-“OPen compiled shader”

Shader "Diffuse" {
Properties {
	_Color ("Main Color", Color) = (1,1,1,1)
	_MainTex ("Base (RGB)", 2D) = "white" {}
}
SubShader {
	Tags { "RenderType"="Opaque" }
	LOD 200

	Pass {
		Name "FORWARD"
		Tags { "LightMode" = "ForwardBase" }
Program "vp" {

Color CubeColor = ObjCube.renderer.material.GetColor("Object名称");　//这样写无法获取物体真实颜色，得到的是（0,0,0,0）　，正确方法是，ObjCube.renderer.material.shader = Shader.Find("Diffuse");        CubeColor = ObjCube.renderer.material.GetColor("_Color");
