Unity用代码实现Remove Missing Script

 1 [MenuItem("Edit/Cleanup Missing Scripts")]
 2  static void CleanupMissingScripts ()
 3  {
 4      for(int i = 0; i < Selection.gameObjects.Length; i++)
 5      {
 6          var gameObject = Selection.gameObjects[i];
 7 
 8          // We must use the GetComponents array to actually detect missing components
 9          var components = gameObject.GetComponents<Component>();
10 
11          // Create a serialized object so that we can edit the component list
12          var serializedObject = new SerializedObject(gameObject);
13          // Find the component list property
14          var prop = serializedObject.FindProperty("m_Component");
15 
16          // Track how many components we‘ve removed
17          int r = 0;
18 
19          // Iterate over all components
20          for(int j = 0; j < components.Length; j++)
21          {
22              // Check if the ref is null
23              if(components[j] == null)
24              {
25                  // If so, remove from the serialized component array
26                  prop.DeleteArrayElementAtIndex(j-r);
27                  // Increment removed count
28                  r++;
29              }
30          }
31 
32          // Apply our changes to the game object
33          serializedObject.ApplyModifiedProperties();
34      }
