cocos2d-x学习（1）-------捕鱼达人的界面实现

时间：2023-02-08 10:50:25

首先做一些说明：

(1)开发工具：

vc2008      cocos2d-2.0-x-2.0.4

(2)实现的效果图(气泡的实际效果，比我做的图片要好许多的，这个要把代码运行起来就知道了)

cocos2d-x学习（1）-------捕鱼达人的界面实现


(3)用到的知识点：

1.CCSprite：   创建图片

2.CCMenuItemImage    CCMenu：创建目录

3.schedule： 定时器

4.CocosDenshion::SimpleAudioEngine::sharedEngine()：播放音乐

5.CocosDenshion::SimpleAudioEngine::sharedEngine()：播放音效

6.CCLog：Log：日志

7.CCRANDOM_0_1():随机数

8.CCMoveTo：移动动画

9.runAction：播放动画方法

10.开启触摸功能：

//set tounch funtion enable
this->setTouchEnabled(true);

void HelloWorld::registerWithTouchDispatcher()
{
    CCDirector* pDirector = CCDirector::sharedDirector();
    pDirector->getTouchDispatcher()->addTargetedDelegate(this, kCCMenuHandlerPriority + 1, true);
}

bool HelloWorld::ccTouchBegan(CCTouch* touch, CCEvent* event)
{
    CCPoint touchLocation = touch->getLocation();
   // updateSize(touchLocation);
	CCLog("ccTouchBegan:touchLocation: touchLocation.x=%.2f ,touchLocation.y:=%.2f",touchLocation.x,touchLocation.y);
    return true;
}

void HelloWorld::ccTouchMoved(CCTouch* touch, CCEvent* event)
{
    CCPoint touchLocation = touch->getLocation();
    //updateSize(touchLocation);
	CCLog("ccTouchMoved:touchLocation: touchLocation.x=%.2f ,touchLocation.y:=%.2f",touchLocation.x,touchLocation.y);
}

void HelloWorld::ccTouchEnded(CCTouch* touch, CCEvent* event)
{
    CCPoint touchLocation = touch->getLocation();
    //updateSize(touchLocation);
	CCLog("ccTouchEnded:touchLocation: touchLocation.x=%.2f ,touchLocation.y=%.2f",touchLocation.x,touchLocation.y);
}


(4)关键代码：

1.HelloWorldScene.h

class HelloWorld : public cocos2d::CCLayer
{
public:

	float locaitonH;
	float maxH;
	float maxW;

    // Here's a difference. Method 'init' in cocos2d-x returns bool, instead of returning 'id' in cocos2d-iphone
    virtual bool init();  

    // there's no 'id' in cpp, so we recommand to return the exactly class pointer
    static cocos2d::CCScene* scene();

	virtual void onEnter();
    
    // a selector callback

	void startGame(CCObject* pSender);
	void selectGame(CCObject* pSender);

	void helpGame(CCObject* pSender);
	void settingGame(CCObject* pSender);

	void updateBubble(float dt);

	//Touch function
	virtual void registerWithTouchDispatcher();

	virtual bool ccTouchBegan(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    virtual void ccTouchMoved(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    virtual void ccTouchEnded(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);

    // implement the "static node()" method manually
    CREATE_FUNC(HelloWorld);
};

2.HelloWorldScene.cpp 

#include "HelloWorldScene.h"

using namespace cocos2d;

    CCScene * scene = NULL;
    do 
    {

        scene = CCScene::create();
        CC_BREAK_IF(! scene);

        // 'layer' is an autorelease object
        HelloWorld *layer = HelloWorld::create();
        CC_BREAK_IF(! layer);

        // add layer as a child to scene
        scene->addChild(layer);
    } while (0);

    // return the scene
    return scene;
}


void HelloWorld::onEnter() 
{ 
    CCLayer::onEnter(); 
}

        pSpriteBg->setPosition(ccp(size.width/2, size.height/2));

        // Add the sprite to HelloWorld layer as a child layer.
        this->addChild(pSpriteBg, 0);

		menu->setPosition(ccp(size.width/2,0));//设置菜单的位置，若不设置则为屏幕的正中间

		//play music
		CocosDenshion::SimpleAudioEngine::sharedEngine()->playBackgroundMusic("background-music.mp3", true);

		//play effect
		//CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect(EFFECT_FILE);
