cocos2dx3.1 触摸没有调用触摸函数

Cocos2d-x
#1

代码：

auto touchListener = EventListenerTouchOneByOne::create();

touchListener->onTouchBegan = &](Touch* t,Event* e){

	log("Begin!!!");

	auto touchLocation = t->getLocation();

	s->setPosition(touchLocation);

	return true;

};

touchListener->onTouchMoved = &](Touch* t,Event* e){

	log("Moved!!!!!!");
};

_eventDispatcher->addEventListenerWithSceneGraphPriority(touchListener,this);



<p> </p>
点击之后没有log输出。<p></p>
<p>而去创建时的menu菜单也无法点击，刚开始能点击  之后就不能点击了，代码是没有问题的 ，重新建一个项目用同样的代码   就能用了，不过我不可能每次都这样吧？</p>
<p>下面是Physics的碰撞检测   也是一点没有log输出</p>
<p></p>
<pre class="""""brush:cpp;"""" toolbar:="""""""" true;="""""""" auto-links:="""""""" false;"="""""""">auto contact = EventListenerPhysicsContact::create();

	contact->onContactBegin = &](const PhysicsContact& contact){

		log(">>>>>>>>>>>>>");

		auto spriteA =(Sprite*) contact.getShapeA()->getBody()->getNode();

		auto spriteB =(Sprite*) contact.getShapeB()->getBody()->getNode();

		if(spriteA->getTag() == 1){

			spriteA->removeFromParentAndCleanup(true);

		}else if(spriteB->getTag() == 1)

		{

			spriteB->removeFromParentAndCleanup(true);

		}

		return false;

	};

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