I am trying to get a edge physics boundary box working however when I touch the node and push it up it then disappears off the screen. Not sure why this is happening when using the following code. Is nodespace the wrong one to use for this. Any help would be greatly appreciated...

bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !Layer::init() )
    {
        return false;
    }
    
    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();
    Size size = Director::getInstance()->getVisibleSize();

    // Physics edge body

    auto edgeBody = PhysicsBody::createEdgeBox( visibleSize  , PhysicsMaterial( 3, 1, 0 ), 3 );
    auto edgeNode = Node::create();
    edgeNode ->setPosition( Point( visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y ) );
    edgeNode->setPhysicsBody( edgeBody );

    
    this->addChild( edgeNode );

    // Test Sprite

    sprite2 = Sprite::create( "CloseNormal.png" );
    sprite2->setPosition( Point( visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y + 200 ) );
        
    auto spriteBody = PhysicsBody::createBox( sprite2->getContentSize( ), PhysicsMaterial( 0, 1, 0 ) );
    spriteBody->setCollisionBitmask(555);
    spriteBody->setContactTestBitmask(true);
        
    sprite2->setPhysicsBody( spriteBody );
        
    this->addChild( sprite2 );

    auto listener1 = EventListenerTouchOneByOne::create();
    // When "swallow touches" is true, then returning 'true' from the onTouchBegan method will "swallow" the touch event, preventing other listeners from using it.
    listener1->setSwallowTouches(true);

    
    listener1->onTouchBegan = CC_CALLBACK_2(HelloWorld::onTouchBegan, this);
    listener1->onTouchMoved = CC_CALLBACK_2(HelloWorld::onTouchMoved, this);
    listener1->onTouchEnded = CC_CALLBACK_2(HelloWorld::onTouchEnded, this);

    _eventDispatcher->addEventListenerWithSceneGraphPriority(listener1, sprite2);

}

bool HelloWorld::onTouchBegan(cocos2d::Touch* touch, cocos2d::Event* event)
{

    auto target = static_cast<Sprite*>(event->getCurrentTarget());
    
    Point locationInNode = target->convertToNodeSpace(touch->getLocation());
    Size s = target->getContentSize();
    Rect rect = Rect(0, 0, s.width, s.height);
    
    
    if (rect.containsPoint(locationInNode) && target == sprite2)
    {
        
        // log("getContentSize... x = %f, y = %f", s., s.height);
        log("sprite two has been touched up");
        log("sprite began... x = %f, y = %f", locationInNode.x, locationInNode.y);
        target->setOpacity(80);
        return true;
    }
    
    
    return false;

};

void HelloWorld::onTouchMoved(cocos2d::Touch* touch, cocos2d::Event* event)
{
    
    auto target = static_cast<Sprite*>(event->getCurrentTarget());
    target->setPosition(target->getPosition() + touch->getDelta());
    
};
