编辑器扩展

菜单项

MenuItem

常用的菜单那位置

1. 整个Unity编辑器顶头的菜单栏；

2. Inspector挂Component的；

3. Hierarchy游戏物体节点树的；

4. Project游戏资源文件的。

验证菜单栏

为某个菜单项写一个bool方法。 第二个参数表示，是否为验证函数

class Program
{
    static void Main(string[] args)
    {
        dynamic dyn = 1;
        object obj = 1;
        dyn = dyn + 3;
        //obj = obj + 3; 报错

        // Rest the mouse pointer over dyn and obj to see their
        // types at compile time.
        System.Console.WriteLine(dyn.GetType());
        System.Console.WriteLine(obj.GetType());
    }
}

自定义快捷键

菜单名称+空格+快捷键 _g 按下字母g 修饰符: % Ctrl; # Shift; & Alt LEFT、RIGHT、UP、DOWN、F1..F12、HOME、END、PGUP、PGDN

class Program
{
    static void Main(string[] args)
    {
        dynamic dyn = 1;
        object obj = 1;
        dyn = dyn + 3;
        //obj = obj + 3; 报错

        // Rest the mouse pointer over dyn and obj to see their
        // types at compile time.
        System.Console.WriteLine(dyn.GetType());
        System.Console.WriteLine(obj.GetType());
    }
}

优先级

默认为1000 差距为11以上分组

给组件或脚本添加右键方法（Inspector）

传入参数 MenuCommand command.context : 被右键点击的脚本对象

class Program
{
    static void Main(string[] args)
    {
        dynamic dyn = 1;
        object obj = 1;
        dyn = dyn + 3;
        //obj = obj + 3; 报错

        // Rest the mouse pointer over dyn and obj to see their
        // types at compile time.
        System.Console.WriteLine(dyn.GetType());
        System.Console.WriteLine(obj.GetType());
    }
}

其他位置

class Program
{
    static void Main(string[] args)
    {
        dynamic dyn = 1;
        object obj = 1;
        dyn = dyn + 3;
        //obj = obj + 3; 报错

        // Rest the mouse pointer over dyn and obj to see their
        // types at compile time.
        System.Console.WriteLine(dyn.GetType());
        System.Console.WriteLine(obj.GetType());
    }
}

ContextMenu & ContextMenuItem

• 写在本身Component脚本中，隶属于UnityEngine命名空间，会被打包。

• 功能和参数与MenuItem完全一致

• 非静态

ContextMenuItem: 给你在右键变量名称时添加菜单 参数:1.菜单的名称；2.菜单执行的方法，要求脚本中必须有；3.按钮的先后顺序。

class Program
{
    static void Main(string[] args)
    {
        dynamic dyn = 1;
        object obj = 1;
        dyn = dyn + 3;
        //obj = obj + 3; 报错

        // Rest the mouse pointer over dyn and obj to see their
        // types at compile time.
        System.Console.WriteLine(dyn.GetType());
        System.Console.WriteLine(obj.GetType());
    }
}
