SceneFadeInAndOut.cs
==============================================================
using UnityEngine;
using System.Collections;
public class SceneFadeInAndOut : MonoBehaviour {
public Material ma;
//初始化
void Start () {
ma = new Material(Shader.Find("Custom/SceneFadeInAndOut")); //创建一个材质
}
//这允许你使用基于shader的过滤器来处理最后的图片,
//进入的图片是source渲染纹理,结果是destination渲染纹理。
void OnRenderImage (RenderTexture source, RenderTexture destination) {
//拷贝源纹理到目的渲染纹理。这主要是用于实现图像效果。
//Blit设置dest到激活的渲染纹理,在材质上设置source作为
//_MainTex属性,并且绘制一个全屏方块。
Graphics.Blit(source, destination, ma);
}
}
