Selection.GetFiltered

Selection

Selection是编辑器类，需要放在在Assets/Editor目录下。

SelectionMode

(摘自：https://docs.unity3d.com/412/Documentation/ScriptReference/SelectionMode.html）

 [MenuItem("Assets/SelectionMode/SelectionMode.Unfiltered")]    public static void SelectUnfiltered()    {        UnityEngine.Object[] arr = Selection.GetFiltered(typeof(UnityEngine.Object), SelectionMode.Unfiltered);        for (int index = 0; index < arr.Length; index++)        {            string filePath = AssetDatabase.GetAssetPath(arr[index]);            Debug.Log("filePath=" + filePath);        }    }

对该目录做操作：

• SelectionMode.Unfiltered
  执行后打印：
  

获得整个选中的对象的路径。但是不遍历。
当选中多个物体（文件夹或者预制件）的时候，打印如下：

• SelectionMode.TopLevel
  当选中一个：跟SelectionMode.Unfiltered结果一致
  当一次选中多个：跟SelectionMode.Unfiltered结果一致
• SelectionMode.Deep
  -能返回所有包括文件夹和预制件的集合
• SelectionMode.ExcludePrefab
  
  选中文件夹和预制件
  打印结果是：
  
  忽略了预制件项！
• SelectionMode.Editable
  This will filter generated prefabs from an imported fbx file but not user created prefabs.
• SelectionMode.Assets
• SelectionMode.DeepAssets
  收集所有包括文件夹，Assets，子文件夹。
  

Selection.GetFiltered

static function GetFiltered (type : Type, mode : SelectionMode) : Object[]

if type is a subclass of Component or GameObject the full SelectionMode is supported.
if type does not subclass from Component or GameObject (eg. Mesh or ScriptableObject) only SelectionMode.ExcludePrefab and SelectionMode.Editable are supported.

如果Type是Component或者GameObject的子类，全部selectionMode都可以支持；
否则SelectionMode.ExcludePrefab and SelectionMode.Editable 类型才支持；
默认是：SelectionMode.TopLevel | SelectionMode.ExcludePrefab | SelectionMode.Editable.
