本文介绍如何在Cocos2d-x中设置触摸监听器，包括onTouchBegan、onTouchMoved和onTouchEnded三个回调函数的具体实现。文章通过代码示例展示了如何创建并注册触摸监听器，并解释了onTouchBegan函数返回值对后续回调的影响。

	//监听器
	auto listener = EventListenerTouchOneByOne::create();
	listener->onTouchBegan = [](Touch * t, Event * e){

		log(" --- onTouchBegan --- ");

		return true;
		//return false;	//此处返回false，则onTouchMoved，onTouchEnded 不会被触发
	};
	listener->onTouchMoved = [](Touch * t, Event * e){

		log(" --- onTouchMoved --- ");
		
		//onTouchMoved 没有返回值
	};
	listener->onTouchEnded = [](Touch * t, Event * e){

		log(" --- onTouchEnded --- ");
		
		//onTouchEnded 没有返回值
	};
	//注册监听器
	Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener, this);
