Hey, thanks, that got it to work. I made the boxes smaller. That config class sure is important.!!

Cool! Everything is organized on that page, and easy to find. (Maybe I should organize the ObjectEditor area )

No, that doesn't do anything. This is so weird. When I first run the program, like after the pc has been rebooted, it removes the canvas without any problems, but upon running it the second time: bang the error.

I ran it on a different laptop than I have been using and it runs ok.

I think I'll just use the GL renderer, instead of trying to support both. Maybe in a new version of lwjgl this will be worked out.  Thanks for the help:)

With that code, it still crashes right when I try to remove the canvas. It even crashes when I try to remove the JPanel.

BTW: What is the purpose of the new FrameBuffer instance in that code?

I forgot that to go to software rendering all I have to do is call disableRenderer(...). I was going to create a whole new FrameBuffer.  Also, I put that new FrameBuffer in the wrong spot; it should go after removing the canvas. This isn't my real code, just what my code does.

I wonder if it is something with the lwjgl, because removing a non-gl-canvas from a jpanel works fine.

Hi, I am trying to get a program to render into a Canvas with the GLRenderer, and then when the container around the Canvas becomes bigger, I need to remove the canvas from its container, create a new framebuffer, and add the new canvas from the framebuffer into the container where the old canvas was. I have everything working up to the point where the canvas is removed. Whenver I try to remove the canvas, the program crashes: no exception or anything just Windows tells me java.exe has caused an error and needs to close. I created some code that is like my real code, and creates the crash.

   public static void main(String args[]){
   final JPanel top = new JPanel();

   World w = new World();

   o.addTriangle(new SimpleVector(0,0,0),new SimpleVector(0,300,0),new SimpleVector(300,0,0));
   o.build();
   w.addObject(o);
   w.setAmbientLight(200,200,200);
   w.newCamera();
   Camera cam = w.getCamera();
   cam.moveCamera(Camera.CAMERA_MOVEOUT,100);
   
   JFrame f = new JFrame();
   f.setLayout(new GridLayout(1,1));
   f.add(top);

         System.out.println("E");
         System.out.println("l1");
            framebuffer.disableRenderer(IRenderer.RENDERER_SOFTWARE);
   System.out.println("About to crash...");
   /** Uncommenting the line below makes the program crash. */
   //top.remove(c);
   
   /**It doesn't matter is you try this. Still the same result: a crash*/
   /*
   SwingUtilities.invokeLater(new Runnable(){
      public void run(){
         top.remove(c);
      }
   });
   */
   }
}

Anybody, know why this happens?
JMan

I tried this little program on another computer, and the jre printed out this message before exiting the program, but windows didn't put up that error dialog

Maybe you have two lights in the world, and one is behind the camera? Or your light is super bright, and you need to move it very far away to see any change in brightness?

Hi,
I uploaded the latest version of the program. It isn't a lot different than the previous version except that how I have the program looking is how it is going to stay. I'm not going to change it again. If someone downloads the app, and has a question about how to do something, just post it here, and I will respond asap.

I was looking around for installers, and I ran across that one. It looks good for distributing on Window, Linux, and Unix, and I hope they will add support for Mac soon.  I don't have a mac, just windows, but since I program in java, it would be nice to deploy the app for all the major platforms. I may use that for my project when I get it done. Also, I don't know if your game will be opensource, but if it is, I found this installer that is free for open source projects.

And I was wondering if you had tried the Eclipse editor and what you thought about it.

No, I never used it;I just heard about it in a java robotics forum.
I've used JCreator, and Netbeans. JCreator is nice, NetBeans is a little slow, and the GUI builder isn't that great.
