Cocos2d-X touch events

Cocos2d-x version 2.1.3

Three steps required to complete a touch event

1. Override the registerWithTouchDispatcher event Method of the parent class.

VirtualvoidregisterWithTouchDispatcher ();

The content is, meaning to re-register in the director class

VoidHelloWorld: registerWithTouchDispatcher () {CCDirector: sharedDirector ()-> getTouchDispatcher ()-> addTargetedDelegate (this, 0, true );}

2. Allow touch. By default, CCLayer does not allow touch. Therefore, you must initialize the init method.

Write

SetTouchEnabled (true );

3. Override the touch method of the parent class

VirtualboolccTouchBegan (CCTouch * touch, CCEvent * event); virtualvoidccTouchMoved (CCTouch * touch, CCEvent * event); virtualvoidccTouchEnded (CCTouch * pTouch, CCEvent * pEvent );

In the first method, a return value is required to indicate whether to accept the touch event. If this parameter is set to true, the message event is not transmitted.
