Cocos2d-x project 101 encounter: 3.0 Click Event, CCTouchDelegate has been disabled

• Cocos2d-x 101 encounter/directory
  1. Installation and environment setup-xcode
  2 Scenes, Director, Layers, Sprites
  3. Create an image menu
  4. Create a new scenario on HelloWorld
  5. Add a sprite.
  5.1 scale down sprite and display it completely
  6 action, mobile sprite
  3.0 Click Event, CCTouchDelegate has been disabled
  8 use the touch event mobile genie

Cocos2d-x 3.0 no longer uses the TouchDelegate method to bundle touch events to sprite.

The new method is

 
 

  
  
 auto listener = EventListenerTouchOneByOne::create();
  
  
 listener->setSwallowTouches(true);
  
  
 listener->onTouchBegan = CC_CALLBACK_2(CMyFirstScene::onTouchBegan, this);
  
  
 listener->onTouchMoved = CC_CALLBACK_2(CMyFirstScene::onTouchMoved, this);
  
  
 listener->onTouchEnded = CC_CALLBACK_2(CMyFirstScene::onTouchEnded, this);
  
  
 _eventDispatcher->addEventListenerWithSceneGraphPriority(listener, this);
 
 

This code can be stored in init in. cpp.

Header file added:

 
 

  
  
 Sprite *s;
  
  
// Initialization
  
  
 
  
  
 bool onTouchBegan(Touch* touch, Event* event);
  
  
 void onTouchMoved(Touch* touch, Event* event);
  
  
 void onTouchEnded(Touch* touch, Event* event);
  
  
 void selectSpriteForTouch(Point touchLocation);
 
 

S is the global genie.

 
 

  
  
bool CMyFirstScene::onTouchBegan(Touch* touch, Event* event)
  
  
{
  
  
 CCLOG("TouchBegan");
  
  
 Point touchLocation = this->convertTouchToNodeSpace(touch);
  
  
 this->selectSpriteForTouch(touchLocation);
  
  
 return true;
  
  
}
  
  

  
  
void CMyFirstScene::onTouchMoved(Touch* touch, Event* event)
  
  
{
  
  
 CCLOG("TouchMoved");
  
  
}
  
  

  
  
void CMyFirstScene::onTouchEnded(Touch* touch, Event* event)
  
  
{
  
  
 CCLOG("TouchEnded");
  
  
}
  
  

  
  
void CMyFirstScene::selectSpriteForTouch(Point touchLocation)
  
  
{
  
  

  
  
 if (s->getBoundingBox().containsPoint(touchLocation) )
  
  
 {
  
  
 Action* actionMove =
  
  
 MoveTo::create( 2.0,
  
  
 ccp(300, 200) );
  
  

  
  
 s->runAction(actionMove);
  
  

  
  
 }
  
  

  
  
}
 
 

In this Code, click on the genie and the genie will move.
