cocos2d-x的CCLayer触摸事件

cocos2d-x版本:2.1.3

编译环境：vs2010(xp)

假如HelloWorldLayer继承了CCLayer类，我要在HelloWorldLayer图层里写多点触摸事件。
1.首先要重写下列三个函数

	virtual void ccTouchesBegan(CCSet *touches,CCEvent *pEvent);
	virtual void ccTouchesMoved(CCSet *touches,CCEvent *pEvent);
	virtual void ccTouchesEnded(CCSet *touches,CCEvent *pEvent);
	virtual void ccTouchesCancelled(CCSet *touches,CCEvent *pEvent);

2.然后在init函数里添加

	setTouchEnabled(true);

3.然后实现上述三个函数

void HelloWorld::ccTouchesBegan( CCSet *touches,CCEvent *pEvent )
{
	CCLOG("Began");
}
void HelloWorld::ccTouchesMoved( CCSet *touches,CCEvent *pEvent )
{
	CCLOG("Moved");
}
void HelloWorld::ccTouchesEnded( CCSet *touches,CCEvent *pEvent )
{
	CCLOG("Ended");
}
void HelloWorld::ccTouchesCancelled(CCSet *touches,CCEvent *pEvent)
{
	CCLOG("Cancelled");
}
