Unity 编辑器扩展之 MenuItem

MenuItem菜单项

说明：创建一个菜单项，并调用其后面的静态函数

1.API和参数

public MenuItem(string itemName, bool isValidateFunction, int priority);

例子:

public class RunGame : MonoBehaviour
  {
    [MenuItem("XRL/Run", priority = 0)]
    static void Run()
    {
      var scenes = EditorBuildSettings.scenes;
      if (scenes.Length > 0)
      {
        var mainScene = scenes[0];
        var isGo = GoToScene(mainScene.path);
        if (isGo)
        {
          EditorApplication.isPlaying = true;
        }
      }
    }

    [MenuItem("XRL/Run", true, priority = 0)]
    static bool IsRun()
    {
      return !Application.isPlaying;
    }

    static bool GoToScene(string path)
    {
      var activeScene = EditorSceneManager.GetActiveScene();
      if (!activeScene.path.Equals(path))
      {
        if (activeScene.isDirty)
        {
          int opration = EditorUtility.DisplayDialogComplex("Scene Have Been Modified", "Do you want to save the change", "Save", "Don't Save", "Cancel");
          switch (opration)
          {
            case 0:
              if (EditorSceneManager.SaveScene(activeScene) == false)
                return false;
              break;
            case 1:
              break;
            case 2:
              return false;
          }
        }

        EditorSceneManager.OpenScene(path);
      }
      return true;
    }
  }

上面代码的作用是运行游戏的第0个场景，注意：当Unity的模式为运行状态时，菜单栏不可点。

isValidateFunction == true

2.设置快捷键

ItemName为菜单路径名称，可以添加菜单快捷键

_w 单一快捷键；

3. 给菜单栏添加菜单

[MenuItem("XRL/AssetBundle/Build")]

给菜单栏添加菜单

4.给 Hierarchy 添加菜单

[MenuItem("GameObject/XRL/TableView", false, 11)]

给 Hierarchy 添加菜单

5. 给 Project 添加菜单

[MenuItem("Assets/AssetBundle/Set AssetBundle By Path")]

给 Project 添加菜单

6. 给组件添加菜单

//[MenuItem("CONTEXT/组件名/方法名")]
