1. 屏幕触摸事件

EventListenerTouchOneByOne ：单点触控

void(conststd::vectorTouch*>&,0); background-color:inherit; font-weight:bold">>onTouchesBegan;//触摸开始事件
1. >onTouchesMoved;//触摸移动事件
2. >onTouchesEnded;//触摸结束事件
3. >onTouchesCancelled;//触摸中断事件

boolTouchTest::init()
1. {
2. if(!Layer::init())
3. returnfalse;
4. }
5. EventDispatcher*eventDispatcher=Director::getInstance()->getEventDispatcher();
6. autolisten=EventListenerTouchAllAtOnce::create();
7. listen->onTouchesBegan=CC_CALLBACK_2(TouchTest::onTouchesBegan,this);
8. listen->onTouchesMoved=CC_CALLBACK_2(TouchTest::onTouchesMoved,this);
9. >onTouchesEnded=CC_CALLBACK_2(TouchTest::onTouchesEnded,0); background-color:inherit; font-weight:bold">>onTouchesCancelled=CC_CALLBACK_2(TouchTest::onTouchesCancelled,108); list-style:decimal-leading-zero outside; color:inherit; line-height:18px"> eventDispatcher->addEventListenerWithSceneGraphPriority(listen,108); list-style:decimal-leading-zero outside; line-height:18px; margin:0px!important; padding:0px 3px 0px 10px!important">
10. returntrue;
11. }
13. //触摸事件开始，手指按下时
14. voidTouchTest::onTouchesBegan(conststd::vector>&touches,cocos2d::Event*event)
15. for(auto&item:touches)
16. autotouch=item;
17. autopos1=touch->getLocation();
18. autopos2=touch->getLocationInView();
19. autopos3=Director::getInstance()->convertToUI(pos2);
20. log("pos1x:%f,y:%f",pos1.x,pos1.y);
21. log("pos2x:%f,pos2.x,pos2.y);
22. log("pos2x:%f,pos3.x,pos3.y);
23. }
24. //触摸移动事件，也就是手指在屏幕滑动的过程
25. voidTouchTest::onTouchesMoved(conststd::vector {
26. log("TouchTestonTouchesMoved");
27. //触摸事件结束，也就是手指松开时
28. voidTouchTest::onTouchesEnded(conststd::vector log("TouchTestonTouchesEnded");
29. //打断触摸事件，一般是系统层级的消息，如来电话，触摸事件就会被打断
30. voidTouchTest::onTouchesCancelled(conststd::vector log("TouchTestonTouchesCancelled");
31. }

获取单击屏幕时的坐标方式：

（1）touch->getLocation(); 获得单击坐标，基于3D

（2）touch->getLocationInView(); 获取单击坐标，是屏幕坐标系的坐标

（3）Director::getInstance()->convertToUI(pos2); //将屏幕坐标系的坐标，转为cocos2dx的坐标

坐标系：cocos2d-x是基于openGLES的，所以遵循openGL的坐标系，也就是说是以屏幕的左下角为坐标原点。屏幕坐标系一般是以左下角为坐标原点。

2. 修改触控方式

//设置多点触控

this->setTouchMode(Touch::DispatchMode::ALL_AT_ONCE);

//设置单点触控

//this->setTouchMode(Touch::DispatchMode::ONE_BY_ONE);

单点触控触摸监听代码：

this->setTouchMode(Touch::DispatchMode::ONE_BY_ONE);
1. autooneTouch=EventListenerTouchOneByOne::create();
2. oneTouch->onTouchBegan=CC_CALLBACK_2(TouchTest::onTouchBegan,108); list-style:decimal-leading-zero outside; line-height:18px; margin:0px!important; padding:0px 3px 0px 10px!important"> oneTouch->onTouchMoved=CC_CALLBACK_2(TouchTest::onTouchMoved,0); background-color:inherit; font-weight:bold">>onTouchEnded=CC_CALLBACK_2(TouchTest::onTouchEnded,0); background-color:inherit; font-weight:bold">>onTouchCancelled=CC_CALLBACK_2(TouchTest::onTouchCancelled,0); background-color:inherit; font-weight:bold">>addEventListenerWithSceneGraphPriority(oneTouch,this);

//设置多点触控
1. this->setTouchMode(Touch::DispatchMode::ALL_AT_ONCE);
2. autolisten=EventListenerTouchAllAtOnce::create();
3. eventDispatcher-3. 屏蔽触摸向下传递

   listen->setSwallowTouches(true);

   setSwallowTouches用于设置是否吞没事件，也就是当某个触摸事件回调的时，截断该事件，让它不能继续传递给其他人。
