Java games rock!

« Posted 2004-07-13 19:38:50 »

I just started playing around with jogl.  And I wrote this example code which ran on my brothers computer, but when I put it on mine, it was giving me this swap buffer error.  How do I fix that?  Now, it runs but doesn't rotate, and then when I try to run it a second time the display is empty.  Also, I inputed this example I got from my professor last semester and his code runs but it is flickering, what causes the flickering?  Here is the code that I wrote if anybody has any suggestions.

import javax.swing.*;

import java.awt.*;   //contains graphicsdevice info

public class Example1 extends JFrame implements GLEventListener
     GLCanvas canvas=null;
     private float m_angle=(float)0.0;
     int width=500;
     int height=500;
     GraphicsEnvironment ge=null;
     GraphicsDevice gd=null;
     GraphicsConfiguration gc=null;
     public Example1()  

           ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
            gd = ge.getDefaultScreenDevice();
             gc = gd.getDefaultConfiguration();

            setTitle("Simple Object");

           GLCapabilities capabilities = new GLCapabilities();

           if( gd.isFullScreenSupported() )


           Animator animator=new Animator(canvas);


     public void init (GLDrawable drawable)

           GL gl = drawable.getGL();
           GLU glu=drawable.getGLU();



     public void display (GLDrawable drawable)
           GL gl=drawable.getGL();

Please move this to the JOGL forums.
