多点触摸的实现步骤与单点触摸类似，setTouchEnabled(true)开启触摸功能，注冊触摸事件，重载多点触摸函数：ccTouchesBegan(開始)、ccTouchesMoved(移动)、ccTouchesEnded(结束)、ccTouchesCancelled(系统中断取消触摸事件)，每一个多点触摸函数都能够通过遍历整个CCSet来获得全部的触点。

 

程序代码：

头文件增加触摸重载函数：

virtual void registerWithTouchDispatcher(void);	virtual void ccTouchesBegan(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent);	virtual void ccTouchesMoved(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent);	virtual void ccTouchesEnded(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent);	virtual void ccTouchesCancelled(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent);

 

cpp文件增加：

setTouchEnabled(true);

 

定义实现这些函数：

void HelloWorld::registerWithTouchDispatcher(){	CCDirector *pdir = CCDirector::sharedDirector();	pdir->getTouchDispatcher()->addStandardDelegate(this, 0);}void HelloWorld::ccTouchesBegan(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent){	CCSetIterator iter = pTouches->begin();	for (; iter != pTouches->end(); iter++)	{		CCTouch* pTouch = (CCTouch*)(*iter);				CCPoint location = pTouch->getLocation();		CCLOG("ccTouchesBegan x: %f, y: %f", location.x, location.y);			}}void HelloWorld::ccTouchesEnded(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent){	CCSetIterator iter = pTouches->begin();	for (; iter != pTouches->end(); iter++)	{		CCTouch* pTouch = (CCTouch*)(*iter);		CCPoint location = pTouch->getLocation();		CCLOG("ccTouchesEnded x: %f, y: %f", location.x, location.y);	}}void HelloWorld::ccTouchesMoved(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent){	CCSetIterator iter = pTouches->begin();	for (; iter != pTouches->end(); iter++)	{		CCTouch* pTouch = (CCTouch*)(*iter);		CCPoint location = pTouch->getLocation();		CCLOG("ccTouchesMoved x: %f, y: %f", location.x, location.y);	}}void HelloWorld::ccTouchesCancelled(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent){	CCSetIterator iter = pTouches->begin();	for (; iter != pTouches->end(); iter++)	{		CCTouch* pTouch = (CCTouch*)(*iter);		CCPoint location = pTouch->getLocation();		CCLOG("x: %f, y: %f", location.x, location.y);	}}
