Answer 1

在cocos2d 3.9中，您可以使用下面解释的块来检测触摸。你可以在onEnter中写下面的代码。详情请查看cocos2d-x编程指南：http://www.cocos2d-x.org/programmersguide/8/index.html

// Create a "one by one" touch event listener 
// (processes one touch at a time) 
auto listener1 = EventListenerTouchOneByOne::create(); 

// trigger when you push down 
listener1->onTouchBegan = [](Touch* touch, Event* event){ 
    // your code 
    return true; // if you are consuming it 
}; 

// trigger when moving touch 
listener1->onTouchMoved = [](Touch* touch, Event* event){ 
    // your code 
}; 

// trigger when you let up 
listener1->onTouchEnded = [=](Touch* touch, Event* event){ 
    // your code 
}; 

// Add listener 
_eventDispatcher->addEventListenerWithSceneGraphPriority(listener1, this);
