Coco2dx 3.0 Beta Touch Events

cocos2d-x C++
#1

This is what I have been doing in a Class that extends Layer to capture touches (One by one). I have no clue if this is correct, I’ve pieced this together from IRC, google searches, and some blog posts.

In my header Private:

	virtual bool onTouchBegan(Touch *pTouches, Event *pEvent);
	virtual void onTouchMoved(Touch *pTouches, Event *pEvent);
	virtual void onTouchCancelled(Touch *pTouch, Event *pEvent);
	virtual void onTouchEnded(Touch *pTouches, Event *pEvent);
	
	//...... .cpp init
	this->setTouchEnabled(true);
	this->setTouchMode(Touch::DispatchMode::ONE_BY_ONE); 
	
	
	touchListener->onTouchBegan = CC_CALLBACK_2(HelloWorld::onTouchBegan, this);
	touchListener->onTouchMoved = CC_CALLBACK_2(HelloWorld::onTouchMoved, this);
	touchListener->onTouchEnded = CC_CALLBACK_2(HelloWorld::onTouchEnded, this);
	touchListener->onTouchCancelled = touchListener->onTouchEnded;
	auto touchListener = EventListenerTouchOneByOne::create();
	Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(touchListener, this);
	
	
	//.........In my .cpp methods
	
	bool HelloWorld::onTouchBegan( Touch *pTouches, Event *pEvent )
	{
		Point point = pTouches->getLocationInView();
		point = convertCoordinate(point);
		
		if(isPointInCircle(point,kCenter,JOYSTICK_RADIUS)){
		isPressed = true;
		this->updateVelocity(point);
	}
	
	return true;
	}
	
	void HelloWorld::onTouchMoved( Touch *pTouches, Event *pEvent )
	{
		if(isPressed){
		//Touch *touch = (Touch*)pTouches->anyObject();
		Point point = pTouches->getLocationInView();
		//Point point = touch->getLocationInView(touch->view());
		point = convertCoordinate(point);
		this->updateVelocity(point);
	}
	}
	
	void HelloWorld::onTouchCancelled( Touch *pTouch, Event *pEvent )
	{
		this->handleLastTouch();
	}
	
	void HelloWorld::onTouchEnded( Touch *pTouches, Event *pEvent )
	{
		this->handleLastTouch();
	}

Thanks!

there is a variable in Node,
_eventDispatcher,
touch event is charged by it, not director, the code is following as:

auto listener = EventListenerTouchOneByOne::create();
listener->onTouchBegan = CC_CALLBACK_2(Miner::touchBegan, this);
listener->onTouchMoved = CC_CALLBACK_2(Miner::touchMoved, this);
listener->onTouchEnded = CC_CALLBACK_2(Miner::touchEnded, this);
listener->setSwallowTouches(false);
_eventDispatcher->addEventListenerWithFixedPriority(listener, -1);

modify:
//… .cpp init
//this->setTouchEnabled(true); --V3 DEPRECATED
//this->setTouchMode(Touch::DispatchMode::ONE_BY_ONE);

auto touchListener = EventListenerTouchOneByOne::create();
touchListener->setSwallowTouches(true);
touchListener->onTouchBegan = CC_CALLBACK_2(HelloWorld::onTouchBegan, this);
touchListener->onTouchMoved = CC_CALLBACK_2(HelloWorld::onTouchMoved, this);
touchListener->onTouchEnded = CC_CALLBACK_2(HelloWorld::onTouchEnded, this);
touchListener->onTouchCancelled = touchListener->onTouchEnded;

_eventDispatcher()->addEventListenerWithSceneGraphPriority(touchListener, this);

//…In my .cpp methods

bool HelloWorld::onTouchBegan( Touch *pTouches, Event *pEvent )
{
//Point point = pTouches->getLocationInView();
//point = convertCoordinate(point);
Point point = pTouches->getLocationInView();

if(isPointInCircle(point,kCenter,JOYSTICK_RADIUS)){
isPressed = true;
this->updateVelocity(point);

}

return true;
}

void HelloWorld::onTouchMoved( Touch *pTouches, Event *pEvent )
{
if(isPressed){
//Touch touch = (Touch)pTouches->anyObject();
Point point = pTouches->getLocation();
//Point point = touch->getLocationInView(touch->view());
//point = convertCoordinate(point);
this->updateVelocity(point);
}
}

void HelloWorld::onTouchCancelled( Touch *pTouch, Event *pEvent )
{
this->handleLastTouch();
}

void HelloWorld::onTouchEnded( Touch *pTouches, Event *pEvent )
{
this->handleLastTouch();
}
