【Unity】Unity Editor菜单按钮扩展_unity eiditer按钮

Unity官方教程：http://unity3d.com/cn/learn/tutorials/modules/intermediate/editor/menu-items?playlist=17090

本博客仅供自己记录要点，一切以官方文档为准。

我们可以通过

using UnityEngine;
using UnityEditor;

public class MenuItems
{
    [MenuItem("Tools/Clear PlayerPrefs")]
    private static void NewMenuOption()
    {
        PlayerPrefs.DeleteAll();
    }
}

来扩展已有/自定义菜单按钮，上述代码中的Tools可替换为Window这样的原有菜单项。

热键

• % – CTRL on Windows / CMD on OSX

• # – Shift

• & – Alt

• LEFT/RIGHT/UP/DOWN – Arrow keys

• F1…F2 – F keys

• HOME, END, PGUP, PGDN

eg.

// Add a new menu item with hotkey CTRL-SHIFT-A

[MenuItem("Tools/New Option %#a")]
private static void NewMenuOption()
{
}

// Add a new menu item with hotkey CTRL-G

[MenuItem("Tools/Item %g")]
private static void NewNestedOption()
{
}

// Add a new menu item with hotkey G
[MenuItem("Tools/Item2 _g")]
private static void NewOptionWithHotkey()
{
}

特殊路径

上面文章中讲到的按钮路径都是普通的位于菜单栏的按钮，但是Untiy是有一些特殊的路径的，比如：

• Assets – items will be available under the “Assets” menu, as well using right-click inside the project view.（我们在Unity的Project下面右击会出现的）

• Assets/Create – items will be listed when clicking on the “Create” button in the project view (useful when adding new types that can be added to the project)（Unity的Project目录下右击->Create下面）

• CONTEXT/ComponentName – items will be available by right-clicking inside the inspector of the given component.（在面板上的组件上右击会出现）

Validation/验证？

有些按钮只有在右击某类东西时才会起作用，所以我们需要验证，例子如下

[MenuItem("Assets/ProcessTexture")]
private static void DoSomethingWithTexture()
{
}

// Note that we pass the same path, and also pass "true" to the second argument.
[MenuItem("Assets/ProcessTexture", true)]
private static bool NewMenuOptionValidation()
{
    // This returns true when the selected object is a Texture2D (the menu item will be disabled otherwise).
    return Selection.activeObject.GetType() == typeof(Texture2D);
}

效果：只有在Texture2D上才会有用

按钮优先级

[MenuItem("NewMenu/Option1", false, 1)]
private static void NewMenuOption()
{
}

[MenuItem("NewMenu/Option2", false, 2)]
private static void NewMenuOption2()
{
}

[MenuItem("NewMenu/Option3", false, 3)]
private static void NewMenuOption3()
{
}

[MenuItem("NewMenu/Option4", false, 51)]
private static void NewMenuOption4()
{
}

[MenuItem("NewMenu/Option5", false, 52)]
private static void NewMenuOption5()
{
}

效果：以10为单位一组

End.除此之外还有MenuCommand、ContextMenu、ContextMenuItem等几个类，跟MenuItem差不多，看顶上的链接吧，另外有
