cocos2d.x单点触摸事件

今天在调简单的单点触摸出发人物发子弹的时候，发现教程里面的代码不能使用。

#include "HelloWorldScene.h"

USING_NS_CC;

Scene* HelloWorld::createScene()
{
    // 'scene' is an autorelease object
    auto scene = Scene::create();
    
    // 'layer' is an autorelease object
    auto layer = HelloWorld::create();

    // add layer as a child to scene
    scene->addChild(layer);

    // return the scene
    return scene;
}

// on "init" you need to initialize your instance
bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
	if ( !LayerColor::initWithColor(ccc4(255,255,255)) )//红 绿 蓝 alpha（透明度）
    {
        return false;
    }
#if 0
    
    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();

    /////////////////////////////
    // 2. add a menu item with "X" image,which is clicked to quit the program
    //    you may modify it.

    // add a "close" icon to exit the progress. it's an autorelease object
    auto closeItem = MenuItemImage::create(
                                           "CloseNormal.png","CloseSelected.png",CC_CALLBACK_1(HelloWorld::menuCloseCallback,this));
    
	closeItem->setPosition(Vec2(origin.x + visibleSize.width - closeItem->getContentSize().width/2,origin.y + closeItem->getContentSize().height/2));

    // create menu,it's an autorelease object
    auto menu = Menu::create(closeItem,NULL);
    menu->setPosition(Vec2::ZERO);
    this->addChild(menu,1);

    /////////////////////////////
    // 3. add your codes below...

    // add a label shows "Hello World"
    // create and initialize a label
    
    auto label = Label::createWithTTF("Hello World","fonts/Marker Felt.ttf",24);
    
    // position the label on the center of the screen
    label->setPosition(Vec2(origin.x + visibleSize.width/2,origin.y + visibleSize.height - label->getContentSize().height));

    // add the label as a child to this layer
    this->addChild(label,1);

    // add "HelloWorld" splash screen"
    auto sprite = Sprite::create("HelloWorld.png");

    // position the sprite on the center of the screen
    sprite->setPosition(Vec2(visibleSize.width/2 + origin.x,visibleSize.height/2 + origin.y));

    // add the sprite as a child to this layer
    this->addChild(sprite,0);
 #endif  

	CCSize screenSize=CCDirector::sharedDirector()->getVisibleSize();//在导演类中获取屏幕高度
    CCSprite* player=CCSprite::create("Player.png");
	player->setPosition(ccp(0+20,screenSize.height/2)); 
	this->addChild(player);
	
#if 0
	CCMenuItemImage* item=CCMenuItemImage::create("button2.png","button2.png",this,menu_selector(HelloWorld::responseFunc));

	item->setPosition(ccp(30,30));
	CCMenu* menu=CCMenu::create(item,NULL);
	this->addChild(menu);
#endif
	this->schedule(schedule_selector(HelloWorld::gameLogic),2);
	this->setTouchEnabled(true);
	setTouchMode(Touch::DispatchMode::ONE_BY_ONE);//原本这一部分是没有的
	return true;

}

bool HelloWorld::onTouchBegan(Touch *pTouches,CCEvent *pEvent)//教程里面使用的是void HelloWorld::ccTouchesEnded这个函数，不过我在使用的时候

//发现该ccTouchesEnded已经是Layer类里面已经定义的了，然后我就直接把他改成void Layer::ccTouchesEnded,但是发现他出现的错误是说ccTouchesEnded已经

//有主体，所以我又翻了一下书，发现可以直接先使用<pre name="code" class="cpp">//setTouchMode(Touch::DispatchMode::ONE_BY_ONE);

//然后利用函数onTouchBagan（<span style="font-family: Arial,Helvetica,sans-serif;">Touch *pTouches,CCEvent *pEvent)</span>

<span style="font-family: Arial,sans-serif;">//利用getLocation（）获取触摸点的坐标。</span>
