Click Event Detection

Directly Add code

Auto dispatcher = Director: getinstance ()-> Geteventdispatcher (); Auto listener = Eventlistenertouchonebyone: Create (); listener -> Ontouchbegan = cc_callback_2 (gamelayer: ontouchbegan, This  ); Listener -> Ontouchmoved = cc_callback_2 (gamelayer: ontouchmoved, This  ); Listener -> Ontouchended = cc_callback_2 (gamelayer: ontouchended,This  ); Dispatcher -> Addeventlistenerwithscenegraphpriority (listener, This  );  Bool Gamelayer: ontouchbegan (touch * touch, event * Event  ){  Return   True  ;}  Void Gamelayer: ontouchmoved (touch * touch, event * Event  ){}  Void Gamelayer: ontouchended (touch * touch, event * Event  ){} 

 

Sprite Detected

 

BoolGamelayer: checktouchali (touch *Touch ){//Converts the click point to the coordinates in the coordinate system, that is, the origin point relative to alisprite (a sprite ).Vec2 Pt = alisprite->Converttouchtonodespace (touch );IntNw = alisprite->Getrect (). Size. width;IntNH = alisprite->Getrect (). Size. height; rect RC (0,0, NW, NH );ReturnRC. containspoint (PT );}
 

Sprite and drag

VoidGamelayer: setalipostotouchpos (touch *Touch) {vec2 PT= Alisprite->Converttouchtonodespace (touch );IntNw = alisprite->Getrect (). Size. width;IntNH = alisprite->Getrect (). Size. height; vec2 touchpos= Vec2 (alisprite-> getpositionx ()-NW *0.5+PT. X, alisprite-> Getpositiony ()-NH *0.5+PT. Y); alisprite->Setposition (touchpos );}
