Cocos2d-x 多点触摸



首先，我们要在.h文件中注册触摸事件的回调方法：

//声明多点触摸的回调方法 void ccTouchesBegan(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent); void ccTouchesMoved(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent); void ccTouchesEnded(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent);



在.cpp文件中的boolHelloWorld::init()函数中添加：

//多点触摸只接受两个参数，不接收是否吞噬触摸事件的参数。 CCDirector::sharedDirector()->getTouchDispatcher()->addStandardDelegate(this, 0);



//触摸开始的回调方法void HelloWorld::ccTouchesBegan(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent){ CCTouch* touch = (CCTouch*)pTouches->anyObject(); CCPoint p = touch->getLocation(); CCLog("触摸开始");}



//触摸移动的回调方法void HelloWorld::ccTouchesMoved(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent){ CCLog("触摸点移动");}



//触摸结束的回调方法void HelloWorld::ccTouchesEnded(cocos2d::CCSet *pTouches, cocos2d::CCEvent *pEvent){ CCLog("触摸结束");}
