Java game development-a few simple lines of code have completed the programming of the driver genie

Today, I wrote a driver genie, and a few lines of code are complete. Although simple, it is very useful, many games developed using java and android use more or less the simple code.

Packagecom. csdn. code;

 

Importjava. awt. Color;

Importjava. awt. Frame;

Importjava. awt. Graphics;

Importjava. awt. event. WindowAdapter;

Importjava. awt. event. javaswevent;

Public classDriveElf extends Frame {

Private int x = 40; // the initial position of the genie on the canvas-abscissa

Private int y = 40; // the initial position of the genie on the canvas-ordinate

Private int arc = 320; // angle of combination of Sprite mouth

Public DriveElf (){

SetBounds (200,200,600,500 );

SetVisible (true );

SetBackground (Color. cyan );

AddWindowListener (new WindowAdapter (){

Public voidwindowClosing (WindowEvent e ){

System. exit (0 );

}

});

New Thread (){

Public void run (){

While (true ){

// Two for loops are used to move the genie on the canvas.

For (inti = 0; I <40; I ++ ){

Arc + = 1;

X + = 10;

Y + = 3;

}

Try {

Thread. sleep (50 );

} Catch (effectione ){

E. printStackTrace ();

}

Repaint ();

For (inti = 0; I <40; I ++ ){

Arc-= 1;

X-= 8;

Y-= 1;

Try {

Thread. sleep (100 );

} Catch (effectione ){

E. printStackTrace ();

}

Repaint ();

}

}

}

}. Start ();

}

// Spray the painting method for drawing on the drawing board

Public void paint (Graphics g ){

G. setColor (Color. red );

G. fillArc (x, y, 90, 90, 0, arc); // draw the sprite body

G. setColor (Color. gray );

G. fillArc (x + 50, y + 10, 20, 20, 0,360); // draw the sprite

G. setColor (Color. black );

G. fillArc (x + 56, y + 15, 10, 10, 0,360); // draw an eye ball

}

Public static void main (String [] args ){

New DriveElf ();

 

}

 

}
