cocos2d-js cc.MenuItem创建菜单项​

cc.MenuItem.create(callback, target)

创建一个空的菜单项，参数说明：

callback  回调函数，用于响应菜单

target  标记项

ctor(callback, target)

构造函数

initWithCallback(callback, target)

初始化一个带回调的菜单项

返回 boolean

isEnabled()

返回菜单是否有效

返回 boolean

isOpacityModifyRGB() setOpacityModifyRGB(value)

只用于jsb

isSelected()

返回菜单是否被选中

返回 boolean

rect()

返回菜单大小（cc.Rect）

selected()

设置菜单选中属性，等同setIsSelected(true)

unselected()

等同setIsSelected(true)

setCallback(callback, target)

设置菜单回调

setEnabled(enable)

设置菜单有效

setTarget(selector, rec)

设置菜单选择器

一. cc.MenuItemLabel

var menuitemLabel = new cc.MenuItemLabel(label,selector,target); cc.MenuItemAtlasFont.create(value, charMapFile, itemWidth, itemHeight, startCharMap, callback, target) // Example var item = cc.MenuItemAtlasFont.create( 'text to display' , 'font.fnt' , 12, 32, ' ' ) //OR var item = cc.MenuItemAtlasFont.create( 'text to display' , 'font.fnt' , 12, 32, ' ' , game.run, game) cc.MenuItemFont(value, callback, target) cc.MenuItemFont.fontName() //getFontName()

获取菜单字体名称

cc.MenuItemFont.fontSize() //getFontSize()

获取菜单字体大小

initWithString(value, callback, target)

初始化菜单

cc.MenuItemFont.setFontName(name)

设置字体

cc.MenuItemFont.setFontSize(fontSize)

设置大小

// Example var item = cc.MenuItemFont.create( "Game start" , 'start' , Game) //创建一个"Game start"菜单, 点击菜单, 运行Game.start() var item = cc.MenuItemFont.create( "Game start" , game.start, Game) //同上 var item = cc.MenuItemFont.create( "i do nothing" ) //创建一个文本菜单，不做任何动作 //还可以设置菜单字体和大小 cc.MenuItemFont.setFontName( 'my Fancy Font' ); cc.MenuItemFont.setFontSize(62);

二 cc.MenuItemSprite

cc.MenuItemSprite.create(normalSprite, selectedSprite, three, four, five) var item = new cc.MenuItemSprite(normalImage) //使用sprite创建一个空menu,无响应函数 var item = new cc.MenuItemSprite(normalImage, selectedImage) //创建一个空menu，点击无反应 var item = new cc.MenuItemSprite(normalImage, SelectedImage, disabledImage) //效果同上, 但会切换到disableImage var item = new cc.MenuItemSprite(normalImage, SelectedImage, 'callback' , targetNode) //创建菜单，回调函数 getNode.callback() var item = new cc.MenuItemSprite(normalImage, SelectedImage, disabledImage, targetNode.callback, targetNode) //效果同上, but with disabled image, and passing in callback function

cc.MenuItemImage.create(normalImage, selectedImage, three, four, five) // Example //create a dom menu item with normal and selected state, when clicked it will run the run function from gameScene object var item = cc.MenuItemImage.create( 'normal.png' , 'selected.png' , 'run' , gameScene) //same as above, but pass in the actual function and disabled image var item = cc.MenuItemImage.create( 'normal.png' , 'selected.png' , 'disabled.png' , gameScene.run, gameScene)

cc.MenuItemToggle() // Example //create a toggle item with 2 menu items (which you can then toggle between them later) var toggler = new cc.MenuItemToggle( cc.MenuItemFont.create( "On" ), cc.MenuItemFont.create( "Off" ), this .callback, this ) //Note: the first param is the target, the second is the callback function, afterwards, you can pass in any number of menuitems //if you pass only 1 variable, then it must be a cc.MenuItem var notYetToggler = new cc.MenuItemToggle(cc.MenuItemFont.create( "On" )); //it is useless right now, until you add more stuff to it notYetToggler.addSubItem(cc.MenuItemFont.create( "Off" )); //this is useful for constructing a toggler without a callback function (you wish to control the behavior from somewhere else)
