扩展Hierarchy之后的效果：
我们调试战斗的时候，需要在Hierarchy界面选中对应的武将，然后操作快捷键控制武将。由于多个操作我觉得比较麻烦，就在网上查找了一下扩展Hierarchy菜单的方法。
代码如下：
[InitializeOnLoadMethod]private static void StartInitializeOnLoadMethod(){EditorApplication.hierarchyWindowItemOnGUI += OnHierarchyGUI;}private static void OnHierarchyGUI(int instanceID, Rect selectionRect){if (!Application.isPlaying)return;var data = Selection.activeGameObject;if (data == null){return;}if (Event.current != null&& selectionRect.Contains(Event.current.mousePosition)&& Event.current.button == 1&& Event.current.type <= EventType.MouseUp&& CheckShow()){Vector2 mousePosition = Event.current.mousePosition;EditorUtility.DisplayPopupMenu(new Rect(mousePosition.x, mousePosition.y, 0, 0), "Tools/战斗脚本控制", null);Event.current.Use();}}[MenuItem("Tools/战斗脚本控制/控制该武将")]public static void SelectGameObject1(){if (Application.isPlaying){var data = Selection.activeGameObject;if (data != null){var roleControll = data.GetComponent<RoleController>();if (roleControll != null){roleControll.PlayerControl = !roleControll.PlayerControl;}}}}private static bool CheckShow(){var data = Selection.activeGameObject;if (data != null){var roleControll = data.GetComponent<RoleController>();if (roleControll != null){return true;}}return false;}
注意一定要添加自己的条件，不然会把Unity原生的菜单覆盖掉。
