Change Matirials Shader —— 改变材质着色状态

一个简单的小例子，没什么可说的

可以很简便的完成一个物体材质 Shader 的动态更改

using UnityEngine;/// <summary>/// 枚举Shader4种状态类型/// </summary>public enum RenderingMode{    Opaque,    Cutout,    Fade,    Transparent,}/// <summary>/// 测试类：用于动态修改Shader/// </summary>public class Chinar : MonoBehaviour{    public Game  CubeGame ; //需要改变Shader的物体    public float      Speed = 15f;    //时间插值    void Update()    {        transform.Rotate(Vector3.up, Speed * Time.deltaTime);    }    /// <summary>    /// 绑定按钮：改变Shader状态    /// </summary>    public void ChangeShader()    {        //设置材质的颜色为半透明的颜色/材质有贴图，那么贴图也必须是半透明的才能看到效果        CubeGame .GetComponent<MeshRenderer>().material.color = RandomColor();        SetMaterialRenderingMode(CubeGame .GetComponent<MeshRenderer>().material, RenderingMode.Transparent);    }    /// <summary>    /// 随机颜色    /// </summary>    /// <returns> Color </returns>    private Color RandomColor()    {        float r     = Random.Range(0f, 1f);        float g     = Random.Range(0f, 1f);        float b     = Random.Range(0f, 1f);        float a     = Random.Range(0f, 0.5f); //这里随机透明度        Color color = new Color(r, g, b, a);        return color;    }    /// <summary>    /// 具体处理材质Shader函数    /// </summary>    /// <param name="material"></param>    /// <param name="renderingMode"></param>    public void SetMaterialRenderingMode(Material material, RenderingMode renderingMode)    {        switch (renderingMode)        {            case RenderingMode.Opaque:                material.SetInt("_SrcBlend", (int) UnityEngine.Rendering.BlendMode.One);                material.SetInt("_DstBlend", (int) UnityEngine.Rendering.BlendMode.Zero);                material.SetInt("_ZWrite",   1);                material.DisableKeyword("_ALPHATEST_ON");                material.DisableKeyword("_ALPHABLEND_ON");                material.DisableKeyword("_ALPHAPREMULTIPLY_ON");                material.renderQueue = -1;                break;            case RenderingMode.Cutout:                material.SetInt("_SrcBlend", (int) UnityEngine.Rendering.BlendMode.One);                material.SetInt("_DstBlend", (int) UnityEngine.Rendering.BlendMode.Zero);                material.SetInt("_ZWrite",   1);                material.EnableKeyword("_ALPHATEST_ON");                material.DisableKeyword("_ALPHABLEND_ON");                material.DisableKeyword("_ALPHAPREMULTIPLY_ON");                material.renderQueue = 2450;                break;            case RenderingMode.Fade:                material.SetInt("_SrcBlend", (int) UnityEngine.Rendering.BlendMode.SrcAlpha);                material.SetInt("_DstBlend", (int) UnityEngine.Rendering.BlendMode.OneMinusSrcAlpha);                material.SetInt("_ZWrite",   0);                material.DisableKeyword("_ALPHATEST_ON");                material.EnableKeyword("_ALPHABLEND_ON");                material.DisableKeyword("_ALPHAPREMULTIPLY_ON");                material.renderQueue = 3000;                break;            case RenderingMode.Transparent:                material.SetInt("_SrcBlend", (int) UnityEngine.Rendering.BlendMode.One);                material.SetInt("_DstBlend", (int) UnityEngine.Rendering.BlendMode.OneMinusSrcAlpha);                material.SetInt("_ZWrite",   0);                material.DisableKeyword("_ALPHATEST_ON");                material.DisableKeyword("_ALPHABLEND_ON");                material.EnableKeyword("_ALPHAPREMULTIPLY_ON");                material.renderQueue = 3000;                break;        }    }}
