Unity 编辑器开发实战【Editor Window】- Replacer 替换器

如图所示，假如一个模型被大量的规整的摆放在场景中，当我们修改了这个模型需要替换时，需要将新模型按照如上位置进行逐个替换比较麻烦，下面介绍的工具Replacer可以很方便的进行批量替换：

在Hierarchy层级窗口选中所有需要替换的模型，然后指定用来替换的模型，点击Replace进行替换

工具代码如下：

  

   

    

     

    
    

     

      using UnityEditor;
     
    
   

    

     

    
    

     

      using UnityEngine;
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      namespace SK.Framework
     
    
   

    

     

    
    

     

      {
     
    
   

    

     

    
    

     
    /// <summary>
     
    
   

    

     

    
    

     
    /// 替换器
     
    
   

    

     

    
    

     
    /// </summary>
     
    
   

    

     

    
    

     
    public class Replacer : EditorWindow
     
    
   

    

     

    
    

     

          {
     
    
   

    

     

    
    

     

              [MenuItem("SKFramework/Replacer")]
     
    
   

    

     

    
    

     
        public static void Open()
     
    
   

    

     

    
    

     

              {
     
    
   

    

     

    
    

     
            var window = GetWindow<Replacer>("Replacer");
     
    
   

    

     

    
    

     

                  window.maxSize = new Vector2(300f, 60f);
     
    
   

    

     

    
    

     

                  window.minSize = new Vector2(300f, 60f);
     
    
   

    

     

    
    

     

                  window.Show();
     
    
   

    

     

    
    

     

              }
