清空多边形碰撞器points

烟雨

对一些不规则添加多边形碰撞器后会自动生成一堆点，还要清掉很麻烦，就写了这么个东西，直接在Inspector上右键clear即可

1. using UnityEngine;
   
2. using System.Collections;
   
3. using UnityEditor;
   
4. 
   
5. public class PolyEditor{
   
6.     [MenuItem("CONTEXT/PolygonCollider2D/Clear")]
   
7.     private static void Clear(MenuCommand mc)
   
8.     {
   
9.         PolygonCollider2D pc2D = mc.context as PolygonCollider2D;
   
10.         pc2D.pathCount = 1;
    
11.         pc2D.SetPath (0,new Vector2[]{Vector2.zero,Vector2.right,Vector2.up});
    
12. 
    
13.     }
    
14. }
