【新手】cocos2d-x监听不到触屏动作，求救！

[luo4188]

不知道为什么监听不到触屏，是按照教程写的代码。
用的是
ccTouchesBegan(CCTouch *pTouch, CCEvent *pEvent);

开发环境：
VS2013，cocos2d-x v2.2.3

求助好心人帮忙，代码如下；

HelloWorldScene.h

//HelloWorldScene.h

    virtual bool init();  

    // there's no 'id' in cpp, so we recommend returning the class instance pointer
    static cocos2d::CCScene* scene();
    
    // a selector callback
    void menuCloseCallback(CCObject* pSender);
    
    // implement the "static node()" method manually
    CREATE_FUNC(HelloWorld);

求大神们帮忙！多谢！！

[luo4188]

难道说与开发环境有关？只有XCODE能这样写，VS不行吗？ 如果是这样的话，要怎么改呢？多谢大神们！

触摸开始响应函数写错了： virtual void ccTouchesBegan(CCSet *pTouches, CCEvent *pEvent); 你重写下这个函数： virtual void registerWithTouchDispatcher(); 试试

[是卖萌的大叔啊]

函数参数改一下 在试试 virtual void ccTouchesBegan(CCSet *pTouches, CCEvent *pEvent);

[allenhiman]

很久没用cc2d了 记得需要开启touch功能 有个什么函数 你是否忘记了呢

[木头呆但不傻]

virtual bool ccTouchBegan(CCTouch* touch, CCEvent* event);

[a87489813]

auto listener = EventListenerTouchOneByOne::create(); 创建一个触摸监听 listener->ccTouchesBegan （重写下） listener->ccTouchesEnd （重写下） _eventDispatcher->addEventListenerWithSceneGraphPriority(listener,对象); //将触摸监听添加到eventDispacher中去

[I'm Daniel Du]

引用 5 楼 Daiwood 的回复:

virtual bool ccTouchBegan(CCTouch* touch, CCEvent* event);

+1，还有触摸相关的几个虚函数都要实现，否则会有奇怪的Bug

[huminghan]

我最近也刚学cocos，5楼说的是 单点触摸，所以是bool型的。 但是lz好像要写多点触摸。 大概看了一下，看你在onEnter() 里面写了注册多点触摸 ，但是为什么给注释掉了？ 我一般是在init里 就把 注册触摸写了 （）。

[香蕉裤衩]

兄弟，我也刚遇到，呵呵。 你看下cocos里TOUCHES的例子就知道了， 现在 需要进行注册监听了。 另外你需要重写下onEnter,onExit.

void Player::onEnter()
{
    Node::onEnter();
    
    // Register Touch Event
    auto listener = EventListenerTouchOneByOne::create();
    listener->setSwallowTouches(true);
    
    listener->onTouchBegan = CC_CALLBACK_2(Player::onTouchBegan, this);
    listener->onTouchMoved = CC_CALLBACK_2(Player::onTouchMoved, this);
    listener->onTouchEnded = CC_CALLBACK_2(Player::onTouchEnded, this);
    
    _eventDispatcher->addEventListenerWithSceneGraphPriority(listener, this);
    
}

2.0和3.0对于触摸的代码不同。 如果是函数重载，函数名就需要写对。

[bianfuba]

建议重载的函数加上override
