Cocos2d-x Touch Screen Response (single touch) cctouchbegan,cctouchmove,cctouchend

COCOS2DX Touch Cctouch A single touch of the class has four functions Cctouchbegan,cctouchmove,cctouchend, Cctouchcancalled.

The functions of these touches do not necessarily respond to each other, but Cctouchbegan must have a return value of bool, and the return value of the other function is void

Below we look at how to touch:

First we create a new project Hello.

1. Hello.h declaration function in source file

1 voidRegisterwithtouchdispatcher (void);//Register Touch2 BOOLCctouchbegan (Cctouch *ptouch, ccevent *pevent);//Touch Start, note the return type, if return false, do not write the following three functions3 voidCctouchmoved (Cctouch *ptouch, ccevent *pevent);//Touch Slide4 voidcctouchended (Cctouch *ptouch, ccevent *pevent);//Touch End5 voidCctouchcancelled (Cctouch *ptouch, ccevent *pevent);//touch cancel such as halfway call

2. Turn on Touch

Join the line where you need to turn on the touch, such as Init

1 BOOL Hello::init () {     settouchenabled (true);     return true; }

3. Implement the Registration function

1 void hello::registerwithtouchdispatcher ()            2 {3     Ccdirector::shareddirector ()->gettouchdispatcher ()->addtargeteddelegate (this0True ); 4 }

4. Realize Cctouchbegan

 1  bool  Hello::cctouchbegan ( Cctouch *ptouch, ccevent *pevent)  2  { 3  ccpoint touchpoint = Ptouch->getlocation (); //  get touch coordinates  4  cclog ( " touch began, Touchpoint is%f   "  5  return       true ; // true indicates that the continuation response Cctouchmove,cctouchend,cctouchcancalled,false is not responding.  6 } 

5. Realize Cctouchmove

1 void Hello::cctouchbegan (Cctouch *ptouch, ccevent *pevent)2{    3     ccpoint touchpoint = Ptouch->getlocation ();         // Get Touch coordinates 4     Cclog ("touch Move, touchpoint is%f", touchpoint); 5 }

6. Realize cctouchended

1 void hello::cctouchended (Cctouch *ptouch, ccevent *pevent)2{3     //   4     cclog ("touch End, touchpoint is%f", touchpoint); 5 }

7. Realize cctouchcancalled

1 void Hello::cctouchcancalled (Cctouch *ptouch, ccevent *pevent)2{    3     ccpoint touchpoint = Ptouch->getlocation ();         // Get Touch coordinates 4     Cclog ("touch End, touchpoint is%f", touchpoint); 5 }
