【Cocosd2d-x CCMenu菜单之二】

 

 

菜单项CCMenuItem是一个基类, 子类CCMenuItemFont、CCMenuItemLabel、CCMenuItemSprite、CCMenuItemToggle可加入CCMenu中形成菜单。

程序代码:

bool HelloWorld::init(){    if ( !CCLayer::init() )    {        return false;    }        CCSize visibleSize = CCDirector::sharedDirector()->getVisibleSize();    CCPoint origin = CCDirector::sharedDirector()->getVisibleOrigin();    CCMenuItemImage *pCloseItem = CCMenuItemImage::create(                                        "CloseNormal.png",                                        "CloseSelected.png",                                        this,                                        menu_selector(HelloWorld::menuCloseCallback));    	pCloseItem->setPosition(ccp(origin.x + visibleSize.width - pCloseItem->getContentSize().width/2 ,                                origin.y + pCloseItem->getContentSize().height/2));    // create menu, it‘s an autorelease object    CCMenu* pMenu = CCMenu::create(pCloseItem, NULL);    pMenu->setPosition(CCPointZero);    this->addChild(pMenu, 1);	//add your code...	//使用字体定义菜单项,包括 CCMenuItemAtlasFont, CCMenuItemFont 两种方式,CCMenuItemFont通过设置字体名称来设置字体。   	CCMenuItemFont::setFontSize(30); //字号  	CCMenuItemFont::setFontName("Courier New");//字体  	CCMenuItemFont *item = CCMenuItemFont::create("--- Go Back ---", this, menu_selector(HelloWorld::menuItemFontcall));//参数1:文字内容,参数2:执行回调函数的目标类,参数3:按下触发的回调函数  	//item->setPosition(ccp(visibleSize.width/2,100));  	//通过字体配置PNG文件的 CCLabelAtlas  	CCLabelAtlas *atlasfont =  CCLabelAtlas::create("0123456789", "labelatlas.png", 16, 24, ‘.‘);//参数顺序:文字内容,图片,单个文字宽,单个文字高,默认显示字符   	CCMenuItemLabel *item1 = CCMenuItemLabel::create(atlasfont, this, menu_selector(HelloWorld::menuItemFontcall2));//参数顺序:文字渲染类,执行回调函数的目标类,按下触发的回调函数    	//item1->setPosition(ccp(visibleSize.width/2,400));  	//精灵菜单项  	CCSprite *spriteNormal   = CCSprite::create("menuitemsprite.png",  CCRectMake(0,23*2,115,23));  	CCSprite *spriteSelected = CCSprite::create("menuitemsprite.png",  CCRectMake(0,23*1,115,23));  	CCSprite *spriteDisabled = CCSprite::create("menuitemsprite.png",  CCRectMake(0,23*0,115,23));  	CCMenuItemSprite* item3 = CCMenuItemSprite::create(spriteNormal, spriteSelected, spriteDisabled, this, menu_selector(HelloWorld::menuCallback3));//参数:3种菜单状态及回调函数  	//item3->setPosition(ccp(visibleSize.width/2,300));  	//通过字体配置FNT类型文件的CCLabelBMFont  	CCLabelBMFont* label = CCLabelBMFont::create("Enable AtlasItem", "bitmapFontTest3.fnt");  	CCMenuItemLabel* item4 = CCMenuItemLabel::create(label, this, menu_selector(HelloWorld::menuCallback4) );  	//item4->setPosition(ccp(visibleSize.width/2+50,250));  	//触发器菜单项,可以将任何菜单项传递进去  	CCMenuItemToggle *toggle = CCMenuItemToggle::createWithTarget(  this,  		menu_selector(HelloWorld::menuCallback5),   		CCMenuItemFont::create("On"),  		CCMenuItemFont::create("Off"),   		NULL);  	//toggle->setPosition(ccp(visibleSize.width/2+100, 150));  	CCMenu *menu = CCMenu::create(item, item1, item3, item4, toggle, NULL); 	menu->alignItemsVertically();		CCSize s = CCDirector::sharedDirector()->getWinSize();	int i=0;	CCNode* child;	CCArray * pArray = menu->getChildren(); //获取menu所有节点(菜单项)	CCObject* pObject = NULL;	CCARRAY_FOREACH(pArray, pObject)	{		if(pObject == NULL)			break;		child = (CCNode*)pObject;		CCPoint dstPoint = child->getPosition();//获取每个节点位置		int offset = (int) (s.width/2 + 50);		if( i % 2 == 0)			offset = -offset;		child->setPosition( ccp( dstPoint.x + offset, dstPoint.y) );//设置菜单项初始位置		child->runAction( 			CCEaseElasticOut::create(CCMoveBy::create(2, ccp(dstPoint.x - offset,0)), 0.35f) //从初始位置移动新的位置,有振幅效果			);		i++;	}	menu->setPosition(ccp(s.width/2, s.height/2));	this->addChild(menu);	return true; }void HelloWorld::menuItemFontcall(CCObject* pSender){	CCLOG("menuItemFontcall...");}void HelloWorld::menuItemFontcall2(CCObject* pSender){	CCLOG("menuItemFontcall2...");}void HelloWorld::menuCallback3(CCObject* pSender){	CCLOG("menuCallback3...");}void HelloWorld::menuCallback4(CCObject* pSender){	CCLOG("menuCallback4...");}void HelloWorld::menuCallback5(CCObject* pSender){	CCLOG("menuCallback5...");}
