概述1. 运动类 （1）移动，拉伸，闪烁，重复动作  MoveTo* moveTo = MoveTo::create(0.9f, Point(250,150));<span style="white-space:pre"> </span>MoveBy* moveBy = MoveBy::create(0.9f, Point(100,100)); sprite->runAction(moveTo)

1. 运动类

（1）移动，拉伸，闪烁，重复动作

	Moveto* moveto = Moveto::create(0.9f,Point(250,150));<span >	</span>MoveBy* moveBy = MoveBy::create(0.9f,Point(100,100));	sprite->runAction(moveto);

Scaleto scaleto = Scaleto::create(0.9f,0.4f,10.f);ScaleBy scaleBy = ScaleBu::create(0.9f,1.0f)

	Blink* blink = Blink::create(3.0f,5);

	JumpBy* jumpBy = JumpBy::create(3.0f,Point(50,1),100,1);	RepeatForever* RepeatForeverAction = RepeatForever::create(jumpBy);	//Repeat* RepeatAction = Repeat::create(jumpBy,5);	sprite->runAction(jumpBy);

	Action* action = Spawn::create(moveto,jumpBy,scaleto,NulL);//几个动作同时做	Action* action = Sequence::create(moveto,NulL);//一个接一个动作

2.动作监听，请看代码

	Moveto* moveHome = Moveto::create(10.0f,100));	auto callbackFunc[&]()	{		log("I fine");	};	CallFunc* callFunc = CallFunc::create(callbackFunc);	Action* actions = Sequence::create(moveHome,callFunc,NulL); 	sprite->runAction(actions);

3.屏幕触摸事件

	auto Listener = EventListenertouchOneByOne::create();	Listener->ontouchBegan = [](touch* touch,Event* event)//手指按下时	{		Point pos1 = touch->getLocation();//基于3D		Point pos2 = touch->getLocationInVIEw();//基于2D，左上角为原点		Point pos3 = Director::getInstance()->convertToGL(pos2);//右下角为原点，笛卡尔坐标，常用的就是这种方式！！！！		log("pos1 x = %f,y = %f,",pos1.x,pos1.y);		log("pos1 x = %f,pos2.x,pos2.y);		log("pos1 x = %f,pos3.x,pos3.y);		return true;	};	Listener->ontouchmoved = [](touch* touch,Event* event)//手指在屏幕拖动时会一直调用	{		log("moved");	};	Listener->ontouchended = [](touch* touch,Event* event)//手指松开时	{		log("end");	};	_eventdispatcher->addEventListenerWithSceneGraPHPriority(Listener,this);//事件管理器注册监听Listener

三个事件，另外一个ontouchCancelled 打断触摸事件，是系统级的消息，如手机来电就会被中断。

4.多点触摸

auto Listener = EventListenertouchAllAtOnce  ::create();Listener->setSwallowtouches(true);//吞没事件，当某个触摸事件回调时，截断这个事件，不让他继续往下传	Listener->ontouchBegan = [](const std::vector<touch*> &touches,Event* event){};	Listener->ontouchmoved = [](const std::vector<touch*> &touches,Event* event)	{		int num = touches.size();		for(auto &touch : touches)		{			auto location = touch->getLocation();		}	};	Listener->ontouchended = [](const std::vector<touch*> &touches,Event* event)	{		auto target = static_cast<Sprite*>(event->getCurrentTarget());//这个只有在监听事件时绑定对象才有效，将最后一句中的this改为绑定的对象。		....	};	_eventdispatcher->addEventListenerWithSceneGraPHPriority(Listener,this);
