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：

@H_874_22@this->setTouchMode(Touch::DispatchMode::ONE_BY_ONE);
1. @H_874_22@autooneTouch=EventListenerTouchOneByOne::create();
2. @H_874_22@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"> @H_874_22@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);

@H_874_22@//设置多点触控
1. @H_874_22@this->setTouchMode(Touch::DispatchMode::all_AT_ONCE);
2. @H_874_22@autolisten=EventListenerTouchAllAtOnce::create();
3. @H_874_22@eventDispatcher-:rgb(153,this);

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。
