Android -- & gt; game framework

 

Note: we have been developing games on the j2's platform for a long time. I want to switch to android this time. I think it's okay to think about it. So I wrote this article.

 

Let's talk about the source code.

 

 

 

Package Sur. Face. Pro;

 

Import android. content. Context;

Import android. graphics. Canvas;

Import android. graphics. Color;

Import android. graphics. Paint;

Import android. util. AttributeSet;

Import android. view. SurfaceHolder;

Import android. view. SurfaceView;

Import android. view. SurfaceHolder. Callback;

 

Public class MySurfaceView extends SurfaceView implements Callback, Runnable {

Public SurfaceHolder sfh;

Public Canvas canvas;

Public Paint paint;

Public static int SC _W, SC _H;

Public MySurfaceView (Context context, AttributeSet attrs ){

Super (context, attrs );

Sfh = getHolder ();

Sfh. addCallback (this); // binding surface to surface view

Paint = new Paint ();

Paint. setAntiAlias (true );

Paint. setColor (Color. RED );

This. setKeepScreenOn (true); // keep screen light

}

 

Public void run (){

Int count = 0;

While (count ++ <20 ){

Logic ();

Paint ();

Sleep ();

}

}

 

Private void logic (){

// Do your logic

}

 

Public void sleep (){

Try {

Thread. sleep (100 );

} Catch (InterruptedException e ){

E. printStackTrace ();

}

}

 

Public void paint (){

Canvas = sfh. lockCanvas (); // obtain the class canvas. Other operations are the same as those of j2s. // do your paint

 

Sfh. unlockCanvasAndPost (canvas );

 

}

 

Public void surfaceCreated (SurfaceHolder holder ){

SC _W = getWidth ();

SC _H = getHeight ();

New Thread (this). start ();

 

}

 

Public void surfaceChanged (SurfaceHolder holder, int format, int width,

Int height ){

 

}

 

Public void surfaceDestroyed (SurfaceHolder holder ){

 

}

 

}
