cocos2dx+KinectV2 体感游戏之微信打飞机

Cocos2dx微信打飞机体感游戏

演示视频地址：点击打开链接 （注 : 视频中两次使用炸弹，没有很好的感应，因为阈值设定有点问题，已改）

1.打飞机添加结束层   √

2.道具双排子弹    √（为了保证游戏趣味性，放50颗子弹后恢复单排子弹）

3.各类飞机的添加  √

4.数据本地化。历史最高成绩的获取 （保存为.xml文件）√

5.随着分数越高，速度越快-----设置参数改变定时器时间(单位时间产生的敌人会越多)和移动一次屏幕距离的时间即可。√

5.体感游戏实现  （一周时间，技术难点较多，主要创新点）√

这里提供一个kinectV2控制鼠标的C++版本程序，同时包含Chengaotan的C#版本程序供参考，Kinect V2 能实现手势识别，石头，箭头和布，因此可以控制鼠标响应不同的点击事件，网上有个人写的鼠标控制，抖动太厉害，我这个还不错，根据chenggaotan C# 程序改写 C++版本 vs2013  戳我打开KinectV2控制鼠标程序。

先讲讲老师们的层次设计，将. 背景 飞机子弹 小敌机 中敌机 大敌机 Food(炸弹) 分门别类的进行分层。

主要的三个场景： start   、   main  、   over

Start 场景：

   看图片，决定屏幕大小，这里在AppDelegate中设计为

pEGLView->setDesignResolutionSize(480, 800, kResolutionExactFit);

   然后预加载一些资源  声音， 图片缓存。在处理资源时候，通常将一类，放在一起。开始头文件如下，接下来只提供cpp文件，因为头文件大同小异。

#ifndef __LayerGameStart_H__#define __LayerGameStart_H__#include "cocos2d.h"USING_NS_CC;class LayerGameStart :public CCLayer{public:static CCScene * scene();CREATE_FUNC(LayerGameStart);bool init();void addStartGamePicture();//预加载游戏背景图片void addPreLoadMusic();   //预加载音乐void toMainGameCallback(); //被回调的};#endif

cpp文件也比较简单

#include "LayerGameStart.h"#include "AppMacros.h"#include "LayerGameMain.h"#include "SimpleAudioEngine.h"using namespace CocosDenshion;  //声音的外部库#define  loadMusic()  CocosDenshion::SimpleAudioEngine::sharedEngine()CCScene * LayerGameStart::scene(){CCScene * scene = CCScene::create();LayerGameStart * layer = LayerGameStart::create();scene->addChild(layer);return scene;}bool LayerGameStart::init(){CCLayer::init();addPreLoadMusic(); //预加载音乐addStartGamePicture();//预加载图片return true;}void LayerGameStart::addStartGamePicture(){// 设置安卓返回键 setKeypadEnabled(true);//加载全局图片信息CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("ui/shoot_background.plist");CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("ui/shoot.plist");//加载当前gamestart页面所需要的图片,动画CCSprite * background = CCSprite::createWithSpriteFrameName("background.png");background->setAnchorPoint(ccp(0, 0));background->setPosition(ccp(0, 0));addChild(background);CCSprite *copyright = CCSprite::createWithSpriteFrameName("shoot_copyright.png");copyright->setAnchorPoint(ccp(0.5, 0));copyright->setPosition(ccp(winSize.width / 2, winSize.height / 2));addChild(copyright);CCSprite *loading = CCSprite::createWithSpriteFrameName("game_loading1.png");loading->setPosition(ccp(winSize.width / 2, winSize.height / 2 - 40));addChild(loading);CCAnimation * animation = CCAnimation::create();animation->setDelayPerUnit(0.2f);char nameBuf[100];for (int i = 0; i < 4; i++){memset(nameBuf, 0, sizeof(nameBuf));sprintf(nameBuf, "game_loading%d.png", i + 1);animation->addSpriteFrame(CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(nameBuf));}CCAnimate *animate = CCAnimate::create(animation);CCRepeat *repeat = CCRepeat::create(animate, 4); //动画播放四次CCCallFunc * loadingDone = CCCallFunc::create(this, callfunc_selector(LayerGameStart::toMainGameCallback));//动画播放完毕回主场景CCSequence * sequence = CCSequence::create(repeat, loadingDone, NULL);loading->runAction(sequence);}void LayerGameStart::addPreLoadMusic(){//加载全局音乐信息loadMusic()->preloadBackgroundMusic("sound/game_music.wav");loadMusic()->preloadEffect("sound/achievement.wav");loadMusic()->preloadEffect("sound/big_spaceship_flying.wav");loadMusic()->preloadEffect("sound/bullet.wav");loadMusic()->preloadEffect("sound/button.wav");loadMusic()->preloadEffect("sound/enemy1_down.wav");loadMusic()->preloadEffect("sound/enemy2_down.wav");loadMusic()->preloadEffect("sound/enemy3_down.wav");loadMusic()->preloadEffect("sound/game_over.wav");loadMusic()->preloadEffect("sound/get_bomb.wav");loadMusic()->preloadEffect("sound/get_double_laser.wav");loadMusic()->preloadEffect("sound/out_porp.wav");loadMusic()->preloadEffect("sound/use_bomb.wav");}void LayerGameStart::toMainGameCallback(){CCScene * scene = LayerGameMain::scene();CCDirector::sharedDirector()->replaceScene(scene);}

此场景会跳到主场景中去，也就是主游戏场景。

上面是主要部分，数据本地化，保存历史最高成绩实现如下：

void LayerGameOver::showScore(){ int score = LayerGameMain::score;//----------------显示最终得分------------------------------//CCString *strScore = CCString::createWithFormat("%d", score);scoreFinalItem = CCLabelBMFont::create(strScore->getCString(), "font/font.fnt");scoreFinalItem->setColor(ccc3(10, 250, 10));scoreFinalItem->setAnchorPoint(ccp(0, 0));scoreFinalItem->setPosition(ccp(winSize.width / 2 - 30, winSize.height / 2));addChild(scoreFinalItem);//----------------------历史最佳成绩显示---------------------//int  BestScore= CCUserDefault::sharedUserDefault()->getIntegerForKey("HistoryHighScore", 0);if (BestScore < score){SimpleAudioEngine::sharedEngine()->playBackgroundMusic("sound/achievement.wav", true);CCUserDefault::sharedUserDefault()->setIntegerForKey("HistoryHighScore", score);CCUserDefault::sharedUserDefault()->flush(); //下次读取前先从内存写入硬盘BestScore = score;}CCString *strHistoryHighScore = CCString::createWithFormat("%d", BestScore);scoreBestItem = CCLabelBMFont::create(strHistoryHighScore->getCString() , "font/font.fnt");scoreBestItem->setColor(ccc3(160, 160, 164));scoreBestItem->setAnchorPoint(ccp(0, 0));scoreBestItem->setPosition(ccp(winSize.width / 2 - 50, winSize.height -70));addChild(scoreBestItem);}

随着游戏得分越高，速度变快和小敌机中敌机大敌机参数设置，用了一个parameter的结构体变量，同时随机化保证飞机间隔不定时间出场，设定一个计数值smallEnemyFrameCount 达到计数值后清零；

void LayerEnemy::reSetframeCount(int degree){switch (degree){case SMALL:{curSmallFramCount = 0;smallEnemyFrameCount = rand() % 8 +  (6 - parameter.smallParameter);break;}case MID:{curMidFrameCount = 0;midEnemyFrameCount = rand() % 15 + (10 - parameter.midParameter);break;}case BIG:{curBigFrameCount = 0;bigEnemyFrameCount = rand() % 25+ (35 - parameter.bigParameter);break;}default:break;}}void LayerEnemy::updateParameter(){int score = LayerControl::getScore();if (score > 1000){int degree =(int ) ((score - 1000) / 500) + 1 ;parameter.smallParameter = degree;if (parameter.smallParameter > 6)  parameter.smallParameter = 6; parameter.midParameter = degree; if (parameter.midParameter > 8) parameter.midParameter = 8;parameter.bigParameter = degree;if (parameter.bigParameter > 12) parameter.bigParameter = 12;}}

这里的体感控制，也就是手势区控制鼠标完成单击，确定，以及拖动飞机

 1 kinect 单例设计  if(!m_Kinect)

{ 

                  m_Kinect = new KinectControl;

                  if (m_Kinect &&m_Kinect->init()){}

                              }

         return m_Kinect;  //模仿cocos2dx设计风格

   2 获取运行窗体相对于整个屏幕坐标 

HWND h =cocos2d::CCEGLView::sharedOpenGLView()->getHWnd(); //获得cocos2dx窗口的句柄

          RECTrt = { 0 };

          ::GetWindowRect(h,&rt);  //得到的既是相对于屏幕左上角的窗口矩形区域

   3 关键两行代码参考chengaotan GitHub 的C#程序，还好C#和MFC大致差不多，勉强看懂。也有用指尖识别的，抖动太剧烈，不过改改采集间隔和加阈值判断应该可以。3个与鼠标操作有关的API  ClipCursor；SetCursorPos；   GetCursorPos

 https://github.com/TangoChen/KinectV2MouseControl

下下来是不能运行了，改了一回才弄好，原来wpf和mfc也类似嘛，不然就GG了。

int  xNow = (int)(curPos.x + (x*mouseSensitivity*lWidth -( curPos.x - rt.left))*smoothing);

int  yNow = (int)(curPos.y + ((y + 0.25f) *mouseSensitivity *lHeight - (curPos.y-rt.top)) * smoothing);

schedule(schedule_selector(LayerControl::kinectUpdate), 0.02f);   //定时器进行鼠标控制

   4 实现KinectV2对鼠标控制后，一开始要让鼠标指向飞机，不同手势代表不同操作。共有三种不同的手势。这里用open代表飞机移动，拳头表示使用bomb（前提是你吃到了bomb），Lasso表示确定，用来返回游戏和退出游戏。

  

这里放一个没有和游戏交互的自己改进的Kinect控制鼠标的代码，和游戏交互，为了一开始就能使鼠标在飞机上，获取了游戏运行窗口在整个屏幕上的坐标，然后将鼠标固定到飞机上

HWND h = cocos2d::CCEGLView::sharedOpenGLView()->getHWnd(); //获得cocos2dx窗口的句柄rt = { 0 };::GetWindowRect(h, &rt);  //得到的既是相对于屏幕左上角的窗口矩形区域Plane * plane = Plane::getInstance();rtNew.left = rt.left + plane->boundingBox().size.width / 3 ;rtNew.right = rt.right - plane->boundingBox().size.width / 2;rtNew.top = rt.top + 30; //加上30为菜单栏的大小rtNew.bottom = rt.bottom - plane->boundingBox().size.height / 2 - 5;TopLeftCorner = { rtNew.left, rtNew.top };  //屏幕左上角lWidth = rtNew.right - rtNew.left;lHeight = rtNew.bottom - rtNew.top;SetCurPositonInPlane();ClipCursor(&rtNew);          //限制光标在矩形区域内

游戏结束场景，可以通过手势剪刀表示确定：

游戏结束代码如下：
