Cocos2d-x Study Notes (3) menu items

The cocos2d-x provides a variety of menu items, including: CCMenuItemLable, CCMenuItemSprite, temperature, temperature, and CCMenuItemImage. They all inherit CCMenuItem, the inheritance diagram is as follows: CCMenuItemLable: mainly including labels and labels. Usage: [cpp] usage: setFontName ("Marker Felt"); CCMenuItemFont: setFontSize (34); usage * pCloseItemFont = CCMenuItemFont: create ("CloseFont", this, menu_selector (HelloWorld: menuCloseCallback); pCloseItemFont-> setPosition (ccp (CCDirector: sharedDirector ()-> getWinSize (). width-100, 20); "CloseFont" is the text menu_selector (HelloWorld: menuCloseCallback) displayed in the menu is a callback function. After clicking the menu, it will call menuCloseC. Allback () function setFontName sets the font of the displayed text setFontSize sets the font size of the displayed text CCMenuItemAtlasFont: [cpp] CCLabelAtlas * pLabelAtlas = CCLabelAtlas: create ("0123456789", "labelatlas ", 16,24 ,'. '); // CCMenuItemLabel * pAtlasFont = CCMenuItemLabel: create (pLabelAtlas, this, menu_selector (HelloWorld: menuCloseCallback) has been mentioned in the previous article )); pAtlasFont-> setPosition (ccp (CCDirector: sharedDirector ()-> getWinSize (). width/2,200); pAtlas Font-> setDisabledColor (ccc3 (32, 32, 64); // The color pAtlasFont when disabled-> setColor (ccc3 (200,200,255 )); // The display color CCMenuItemAtlasFont is used to generate a menu item through the png file, that is, the image corresponding to the configuration file can also be used with the following :: create ("HelloWorld", "dmTest. fnt "); CCMenuItemLabel * pBMFont = CCMenuItemLabel: create (pLabelBMFont, this, menu_selector (HelloWorld: menuCloseCallback); pBMFont-> setPosition (ccp (CCDire Ctor: sharedDirector ()-> getWinSize (). width/2,160); pBMFont-> setScale (0.8f); because the font size cannot be set, use the setScale function to scale CCMenuItemSprite: Image menu: including CCMenuItemImage, you can encapsulate the image to enter the menu item: [cpp] CCSprite * pSt1 = CCSprite: create ("Normal.png"); // CCSprite is the genie class CC_BREAK_IF (! PSt1); CCSprite * pSt2 = CCSprite: create ("Selected.png"); CC_BREAK_IF (! PSt2); CCSprite * pSt3 = CCSprite: create ("Disabled.png"); CC_BREAK_IF (! PSt3) vertex * pSprites = CCMenuItemSprite: create (pSt1, pSt2, pSt3, this, menu_selector (HelloWorld: menuCloseCallback); pSprites-> setPosition (ccp (CCDirector :: sharedDirector ()-> getWinSize (). width-20, 60); CCMenuItemImage: [cpp] CCMenuItemImage * pCloseItem = condition: create ("CloseNormal.png", "CloseSelected.png", this, menu_selector (HelloWorld :: menuCloseCallback); CC_BREAK_IF (! PCloseItem); pCloseItem-> setPosition (CCDirector: sharedDirector ()-> getWinSize (). width-20, 20); CCMenuItemToggle: Any CCMenuItem can be encapsulated. As a switch button, its parameters are variable, that is to say, you can encapsulate multiple [cpp] at once. // zookeeper * pToggle = secret: createWithTarget (this, menu_selector (HelloWorld: menuCloseCallback), CCMenuItemImage: create ", "testToggle2.png"), CCMenuItemImage: create ("tes TToggle2.png "," testToggle.png "), NULL); pToggle-> setPosition (ccp (CCDirector: shareddire()-> getWinSize (). width-350, 20); finally, you need to Create a menu to add all menu items to [cpp] // Create a menu with the "close" menu item, it's an auto release object. CCMenu * pMenu = CCMenu: create (pCloseItem, pCloseItemFont, pCloseItemLabel, pToggle, pSprites, pAtlasFont, NULL); pMenu-> setPosition (CCPointZero); cancel (! PMenu); // Add the menu to HelloWorld layer as a child layer. this-> addChild (pMenu, 1); [cpp] void HelloWorld: menuCloseCallback (CCObject * pSender) // The menu item callback function {// "close" menu item clicked CCDirector:: sharedDirector ()-> end ();}
