How generate touch event?

cocos2d-x C++
#1

I have draggable SpriteA. I start drag when touch began on it, move if touch moving and place on field when touch is ended. Also i have a button SpriteB if touch began on it:

  1. SpriteB hided
  2. SpriteA crated in touch location
  3. SpriteA start draggin
    But SpriteA dont dragging because dont receive touch event. How can i pass touch event on it?

PS. Simple calling ccTouchBegan on SpriteA dont work.

PSS. Sorry for my terrible English.

Hi, Serg Merg,
Try my solution below.

class HelloWorld : public cocos2d::CCLayer
{
public:
    virtual ~HelloWorld();
    // Here's a difference. Method 'init' in cocos2d-x returns bool, instead of returning 'id' in cocos2d-iphone
    virtual bool init();  

    // there's no 'id' in cpp, so we recommand to return the exactly class pointer
    static cocos2d::CCScene* scene();

    // a selector callback
    virtual void menuCloseCallback(cocos2d::CCObject* pSender);

    // implement the "static node()" method manually
    LAYER_NODE_FUNC(HelloWorld);
    virtual void registerWithTouchDispatcher();
    virtual bool ccTouchBegan(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    virtual void ccTouchEnded(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    virtual void ccTouchCancelled(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    virtual void ccTouchMoved(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    cocos2d::CCSprite* m_pSpriteA;
    cocos2d::CCSprite* m_pSpriteB;
    bool m_bSpriteBPressed;
};

void HelloWorld::registerWithTouchDispatcher()
{
    CCTouchDispatcher::sharedDispatcher()->addTargetedDelegate(this, 0, true);
}

bool HelloWorld::ccTouchBegan(CCTouch* touch, CCEvent* event)
{
    CCPoint touchLocation = touch->locationInView( touch->view() ); 
    touchLocation = CCDirector::sharedDirector()->convertToGL( touchLocation );

    if (CCRect::CCRectContainsPoint(m_pSpriteB->boundingBox(), touchLocation))
    {// touch b sprite
        m_pSpriteB->setIsVisible(false);
        m_bSpriteBPressed = true;
    }

    return true;
}

void HelloWorld::ccTouchEnded(CCTouch* touch, CCEvent* event)
{
    if (m_bSpriteBPressed)
    {
        CCPoint touchLocation = touch->locationInView( touch->view() ); 
        touchLocation = CCDirector::sharedDirector()->convertToGL( touchLocation );
        m_bSpriteBPressed = false;
        m_pSpriteB->setIsVisible(true);
        m_pSpriteA->setPosition(touchLocation);
    } 
}

void HelloWorld::ccTouchCancelled(CCTouch* touch, CCEvent* event)
{
}

void HelloWorld::ccTouchMoved(CCTouch* touch, CCEvent* event)
{
    if (!m_bSpriteBPressed)
    {
        return;
    }
    CCPoint touchLocation = touch->locationInView( touch->view() ); 
    CCPoint prevLocation = touch->previousLocationInView( touch->view() );  

    touchLocation = CCDirector::sharedDirector()->convertToGL( touchLocation );
    prevLocation = CCDirector::sharedDirector()->convertToGL( prevLocation );

    m_pSpriteA->setPosition(touchLocation);
}
