创建3D模型/添加屏幕监听，点击屏幕时，精灵带有旋转的移动



3D模型创建 //3D models
   
     auto model = Sprite3D::create("Sprite3DTest/boss1.obj");
   
     model->setScale(4);
   
     model->setTexture("Sprite3DTest/boss.png");
   
     model->setPosition3D(Vec3(s.width/2, s.height/2, 0));
   
     addChild(model);

EventListenerTouchOneByOne 监听
 EventListenerTouchOneByOne* _lis = EventListenerTouchOneByOne::create();
 _lis->onTouchBegan = [this](Touch* t,Event* e){
  CCLOG("onTouchBegan");
  return true; 
 };
 _lis->onTouchMoved = [this](Touch* t,Event* e){
  CCLOG("onTouchMoved");
  float dx = t->getDelta().x;
  Vec3 rot = _camControlMode->getRotation3D();
  rot.y += dx;
  _camControlMode->setRotation3D(rot);
  Vec3 woldPos;
  _camNode ->getNodeToWorldTransform().getTranslation(&woldPos);
  Camera::getDefaultCamera()->setPosition3D(woldPos);
  Camera::getDefaultCamera()->lookAt(_camControlMode->getPosition3D());
 };
 Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(_lis,this);

添加屏幕监听，点击屏幕时，精灵带有旋转的移动
