MenuItem 菜单项
Inherits from System.Attribute
The MenuItem attribute allows you to add menu items to the main menu and inspector context menus.
MenuItem属性允许你添加菜单项到主菜单和检视面板上下文菜单。
Note: This is an editor class. To use it you have to place your script in Assets/Editor inside your project folder. Editor classes are in the UnityEditor namespace so for C# scripts you need to add "using UnityEditor;" at the beginning of the script.
注意：这是一个编辑器类，如果想使用它你需要把它放到工程目录下的Assets/Editor文件夹下。编辑器类在UnityEditor命名空间下。所以当使用C#脚本时，你需要在脚本前面加上 "using UnityEditor"引用。
The MenuItem attribute turns any static function into a menu command. Only static functions can use the MenuItem attribute.
MenuItem属性把任意静态函数变成为一个菜单命令。仅静态函数能使用这个MenuItem属性。
To create a hotkey you can use the following special characters: % (ctrl on Windows, cmd on OS X), # (shift), & (alt), _ (no key modifiers). For example to create a menu with hotkey shift-alt-g use "GameObject/Do Something #&g". To create a menu with hotkey g and no key modifiers pressed use "GameObject/Do Something _g". A hotkey text must be preceded with a space character ("GameObject/Do_g" won't be interpreted as hotkey, while "GameObject/Do _g" will).
可以使用一下指定字符创建热键：% (Windows上为ctrl, OS X上为cmd), # (shift), & (alt), _ (无修改键)。例如创建一个菜单热键为shift-alt-g使用GameObject/Do Something #&g。创建一个菜单热键g并没有修改键（组合键），使用GameObject/Do Something _g。热键文本必须在前面加一个空格字符（GameObject/Do_g不会被解释为热键，而是GameObject/Do _g这样，注意_g前面有空格）。
// C# example:
using UnityEditor;
using UnityEngine;
class MenuTest : MonoBehaviour {
// Add menu named "Do Something" to the main menu
//添加菜单名为Do Something 到主菜单
[MenuItem ("GameObject/Do Something")]
static void DoSomething () {
Debug.Log ("Perform operation");
}
// Validate the menu item.
//验证菜单项。
// The item will be disabled if no transform is selected.
//如果没有变换被选择，该项将是禁用的。
[MenuItem ("GameObject/Do Something", true)]
static bool ValidateDoSomething () {
return Selection.activeTransform != null;
}
// Add menu named "Do Something" to the main menu
//添加菜单名为Do Something 到主菜单
// and give it a shortcut (ctrl-o on Windows, cmd-o on OS X).
//并且指定快捷键（windows为ctrl-o，OS X为cmd-o）
[MenuItem ("GameObject/Do Something %o")]
static void DoSomething () {
Debug.Log ("Perform operation");
}
// Add context menu named "Do Something" to rigid body's context menu
//添加上下文菜单名为Do Something 到刚体的上下文菜单
[MenuItem ("CONTEXT/Rigidbody/Do Something")]
static void DoSomething (MenuCommand command) {
Rigidbody body = (Rigidbody)command.context;
body.mass = 5;
}
}// JavaScript example:
// Add menu named "Do Something" to the main menu
//添加菜单名为Do Something 到主菜单
@MenuItem ("GameObject/Do Something")
static function Something () {
Debug.Log ("Perform operation");
}
// Validate the menu item.
//验证菜单项。
// The item will be disabled if no transform is selected.
//如果没有变换被选择，该项将是禁用的。
@MenuItem ("GameObject/Do Something", true)
static function ValidateDoSomething () {
return Selection.activeTransform != null;
}
// Add menu named "Do Something" to the main menu
//添加菜单名为Do Something 到主菜单
// and give it a shortcut (ctrl-o on Windows, cmd-o on OS X).
//并且指定快捷键（windows为ctrl-o，OS X为cmd-o）
@MenuItem ("GameObject/Do Something %o")
static function SomethingAgain () {
Debug.Log ("Perform operation");
}
// Add context menu named "Do Something" to rigid body's context menu
//添加上下文菜单名为Do Something 到刚体的上下文菜单
@MenuItem ("CONTEXT/Rigidbody/Something")
static function Something (command : MenuCommand) {
var body : Rigidbody = command.context;
body.mass = 5;
