10.COCOS2DX C + + adds touch event listener to Sprite

1. First header file defines function prototypes for event handling

1 Private : 2     bool Ontouchbegan (touch* ttouch,event* eevent); // Finger Press the event 3     void ontouchmoved (touch* ttouch,event* eevent); // Finger Move Event 4     void ontouchended (touch* ttouch,event* eevent); // Finger Leave event

2. Implementing prototypes

1 BOOLShopitem::ontouchbegan (touch* ttouch,event*eevent) {2  　 if(Sprite->getboundingbox (). Containspoint (Ttouch->getlocation ())) {//determine if the touch point is within the target range3  4  　　　　 /** Here is the event content **/5  　　　　 return true;6}Else7  　　　　 return false;8 }9 }Ten   One voidShopitem::ontouchmoved (touch* ttouch,event*eevent) { A     /** Here is the event content **/ - } -   the voidshopitem::ontouchended (touch* ttouch,event*eevent) { -     /** Here is the event content **/ -}

3. Binding Events

1     Auto Listener = eventlistenertouchonebyone::create (); 2      This ); 3      This ); 4      This ); 5     This->geteventdispatcher ()->addeventlistenerwithscenegraphpriority (Listener, Sprite);
