cocos2d-x 3.x 触摸事件

HelloWorldScene.h

   bool touchBegan(cocos2d::Touch*touch, cocos2d::Event*event);//触摸开始,返回bool类型
    void touchMoved(cocos2d::Touch*touch, cocos2d::Event*event);
    void touchEnded(cocos2d::Touch*touch, cocos2d::Event*event);
    void touchCancelled(cocos2d::Touch*touch, cocos2d::Event*event);

HelloWorldScene.cpp

   EventListenerTouchOneByOne*listener=EventListenerTouchOneByOne::create();
    listener->onTouchBegan=CC_CALLBACK_2(HelloWorld::touchBegan,this);//触摸开始,必须添加,不使用也要添加,否则运行不通过
    listener->onTouchMoved=CC_CALLBACK_2(HelloWorld::touchMoved,this);//触摸移动
    listener->onTouchEnded=CC_CALLBACK_2(HelloWorld::touchEnded,this);//触摸中断,一般是系统层级的消息,如来电话,触摸事件就会被打断 
    listener->onTouchCancelled=CC_CALLBACK_2(HelloWorld::touchCancelled,this);
    _eventDispatcher->addEventListenerWithSceneGraphPriority(listener,this);

}
