Unity3D将物体的所有子物体设置为半透明

第一步:

添加一个类,挂到物体的父物体上.如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class BaseWallControl : MonoBehaviour {

    // Use this for initialization
    void Start () {
        for(int i=0;i         {
            Transform wallTransform = gameObject.transform.GetChild(i);
            Color mcolor = wallTransform.gameObject.GetComponent().material.color;
            mcolor.a = 0.4f;
            YPTools.SetMaterialRenderingMode(wallTransform.gameObject.GetComponent().material, YPTools.RenderingMode.Transparent);
            wallTransform.gameObject.GetComponent().material.color = mcolor;
        }
    }
 
    // Update is called once per frame
    void Update () {
        
    }
}
 

第二步,添加上面类中需要的一个工具类的方法.

public static class YPTools {

   ///

    /// 设置Rendering Mode
    ///

    ///
    ///
    public static 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;
        }
    }

}
