cocos2d-x的CCLayer觸摸事件

cocos2d-x版本:2.1.3

編譯環境：vs2010(xp)

假如HelloWorldLayer繼承了CCLayer類，我要在HelloWorldLayer圖層裏寫多點觸摸事件。
1.首先要重寫下列三個函數

	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.然後在init函數裏添加

	setTouchEnabled(true);

3.然後實現上述三個函數

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");
}
