Unity 编辑器开发实战【Editor Window】- BlendShape调试工具

Skin Mesh Renderer组件编辑器本身包含BlendShape的调试滑动条，但是当数量较多想要重置时较为麻烦，下面介绍的工具添加了这些调试滑动条的同时，增加了一键重置的功能：

代码如下：

  

   

    

     

    
    

     

      using UnityEngine;
     
    
   

    

     

    
    

     

      using UnityEditor;
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      namespace SK.Framework
     
    
   

    

     

    
    

     

      {
     
    
   

    

     

    
    

     
    /// <summary>
     
    
   

    

     

    
    

     
    /// BlendShape调试工具
     
    
   

    

     

    
    

     
    /// </summary>
     
    
   

    

     

    
    

     
    public class BlendShapesPreviewer : EditorWindow
     
    
   

    

     

    
    

     

          {
     
    
   

    

     

    
    

     
        //菜单
     
    
   

    

     

    
    

     

              [MenuItem("SKFramework/Tools/BlendShapes Previewer")]
     
    
   

    

     

    
    

     
        private static void Open()
     
    
   

    

     

    
    

     

              {
     
    
   

    

     

    
    

     

                  GetWindow<BlendShapesPreviewer>("BlendShapes Previewer").Show();
     
    
   

    

     

    
    

     

              }
