Cocos2d-x 多点触摸

标签：class   blog   c   code   a   int   

多点触摸的实现步骤与单点触摸类似，setTouchEnabled(true)开启触摸功能，注册触摸事件，重载多点触摸函数：ccTouchesBegan(开始)、ccTouchesMoved(移动)、ccTouchesEnded(结束)、ccTouchesCancelled(系统中断取消触摸事件)，每个多点触摸函数都可以通过遍历整个CCSet来获得所有的触点。

程序代码：

头文件加入触摸重载函数：

              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文件加入：

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);


	}
}
