Qt-based games-battle against bacterial viruses

It seems that bird flu has appeared again recently. People may have experienced SARS, bird flu, and many such epidemics. People seem strange about this. Anyway, I am calm and don't worry about anything in the canteen. Well, I don't need to talk much about it. First, let's make a picture (it's not easy to write, please try it out ):

Main Interface of the bacterial virus war

There are four modes;

Single-user attack mode: Control the direction of red blood cell movement through a, S, D, W, and control the transmitting antibody through the left and right mouse keys to eliminate the flu virus;

Double Attack Mode:Through a, S, D, W and I, J, K, L, the movement direction of the two red blood cells is controlled, and then the two red blood cell transmitting antibodies are controlled through X, C, n, m, respectively;

Single and Double defense modes:Control the red blood cell to avoid viruses (hitting the virus will consume the life value );

This game has sound effects. The longest survival time in double mode is the winner.

Single-user attack mode: (artist OK)

Double Attack Mode:

In-game sound is implemented through the qsound class:

 

Public Member

• Qsound(Const qstring & filename, qobject * parent = 0, const char * name = 0)
• ~ Qsound()
• Int
  Loops() Const
• Int
  Loopsremaining() Const
• Void
  Setloops(Int l)
• Qstring
  Filename() Const
• Bool
  Isfinished() Const

Public slot

• Void
  Play()
• Void
  Stop()

Static Public Member

• Bool
  Isavailable()
• Void
  Play(Const qstring & filename)
• BoolAvailable()

For example, playing background music:

 

 

void BackGroundMusicThread::playBackGroundSound(const QString filename){    if( this->backgroudSound!=NULL )    {        this->backgroudSound->destroyed();        delete this->backgroudSound;        this->backgroudSound = new  QSound(filename);        this->backgroudSound->play();    }}

 

Playing background music, inheriting the qthread class:

 

class BackGroundMusicThread : public QThread{    Q_OBJECTpublic:    explicit BackGroundMusicThread(QObject *parent = 0);    ~BackGroundMusicThread();    void playBackGroundSound();    void playBackGroundSound(const QString fileName);    void setSoudnLoop(int lo);    void run();signals:    public slots:private:    QSound *backgroudSound;    QObject *parentWidget;};

In this way, the abstract function run () can play the desired sound at the end of the game.

 

 

void BackGroundMusicThread::run(){        qDebug() << "IN THREAD RUN...............................";        this->setSoudnLoop(2);  //   play this music 2 times        this->playBackGroundSound();        while(true)        {            if( ((Widget*)(this->parentWidget))->isGameOver() )            {                Resource *resource = new Resource();                QSound *gameoverSound = new QSound(resource->picLocation+"gameover.wav");                delete resource;                gameoverSound->play();                if( gameoverSound->isFinished())                {                    delete gameoverSound;                }            }            if( ((Widget*)(this->parentWidget))->isExit())            {                break;            }        }        qDebug() << "THREAD RUN STOP...............................";}

 

The buttons are implemented by inheriting the mouseeven In the Widget:

 

    void mouseMoveEvent(QMouseEvent *);    void mousePressEvent(QMouseEvent *);    void mouseReleaseEvent(QMouseEvent *);    void keyPressEvent(QKeyEvent *);    void keyReleaseEvent(QKeyEvent *);

Code:

 

 

void Widget::mouseMoveEvent(QMouseEvent *event){    if( Startgame )    {            world->setMousePos(event->x(),event->y());    }}void Widget::mousePressEvent(QMouseEvent *event){    qDebug() << "mouse event type :" << event->type();    if( this->world->getMode() == SINGLE_ATTACK_PLAYER)    {        if ( Startgame )        {            world->fireFlag = true;            this->world->setKeyP(event->button());        }    }}void Widget::mouseReleaseEvent(QMouseEvent *event){   qDebug() << "mouse event type :" << event->type();   if( this->world->getMode() == SINGLE_ATTACK_PLAYER)   {       if( Startgame )       {            world->fireFlag = false;            this->world->setKeyR(event->button());       }   }}

In setkeyr and setkeyp, obtain the key values of the key and the release key:

 

 

void World::setKeyP(int k){    switch(this->getMode())    {        case SINGLE_ATTACK_PLAYER:            //play one            if(k==Qt::Key_W)  //up                key['w'] =  true;            if(k==Qt::Key_S) //down                key['s'] =  true;

The main idea of this game is:

Animation effect implementation: Inherits the paint method of the widget, and calculates the location of 'Influenza virus 'and 'Red cell' during each re-painting.

The effect of virus on red blood cells:Each influenza virus has its own motion direction attribute. During each re-painting, the angle between the motion direction of each influenza virus and the coordinate line between its own coordinates and the red blood cell is calculated, then, reduce the angle by a certain percentage, and then calculate the new coordinates of the influenza virus. After re-painting multiple times, the effect of influenza virus on red blood cells can be displayed.

In the project file QT game is compiled successfully in Windows (of course, it is also possible in Linux), the tool is: qt-windows-opensource-5.0.0-msvc2010_32-x86-offline (installed by default vs2010 ), below is a click to open the link. If you cannot download the Internet, there are also a lot of links, you need to compile it again after installation:
