Well, I bit the bulllet and got the latest CVS. After changing the CubeTest to use jsr231, all seems well. I would recommend though that you guys update your downloadable build a little more often, and maybe update the demos so that they can use different renderers "out of the box". It would lower the initial frustration somewhat. It was easy for me because I'm on Mac OS X and CVS is "built in", but Windows people might not be happy with the trouble they have to go to just to get a working build. Also, it might help if there was a more prominent link on the xith3d.org page to the CVS - on initial glance, it looks like the release is all that is there.

Hmmm. That's not really a good solution for me. I'd like to be able to keep that version of JOGL since I already have code that works with it. I'd love to try out Xith3d. Will newer versions of Xith3d support the new JOGL? When can we expect a new release? Are there developer builds that already support the new JOGL? Thanks

I already had a JOGL release installed (JSR-231 beta 03, Feb 17 2006) when I installed the Xith3D release (Aug-31-2005), but they don't seem compatible. When I try "java -cp libs/xith3d.jar com.xith3d.test.CubeTest", I get the following error: Exception in thread "main" java.lang.NoClassDefFoundError: net/java/games/jogl/GLEventListener I know JOGL works, because I've used it in other programs. Looking at the JOGL library, there is no net.java.games.jogl package. So, I'm guessing that JOGL has changed and Xith hasn't caught up? Or is there something else going on? Can someone please explain?

I never would have thought to look there .. thanks all.

Game Development / Newbie & Debugging Questions / Re: Reading an Image into an IntBuffer for textures

on: 2006-03-11 00:28:07

If you're using jogl, consider the com.sun.opengl.util.texture package. It lets you do this:

1
2
3

Texture myTexture;
URL url = new URL("data/texture.png");
myTexture = TextureIO.newTexture(url, mipmapped, null);

(you need some exception handling in there too, but you get the gist)

Then, when you want to use the texture in your rendering:

1	myTexture.bind();

Pretty simple.

6	Game Development / Newbie & Debugging Questions / "Capturing" the mouse in a Frame or JPanel	on: 2006-03-11 00:08:31
When the user puts the mouse cursor in a certain frame, I would like to make the pointer disappear and capture the mouse's movement until the button is released. However, I'd ALSO like the mouse cursor to remain where it was when the user originally started the drag. I understand how to use MouseListener, MouseMotionListener, and MouseWheelListener, and I'm also pretty sure I can make the cursor disappear. The tricky part seems to be keeping the mouse cursor from moving. How can I do that? Is there some way I can move the cursor to an arbitrary point? It seems like there is probably an interface to do that, but I can't find it... Thanks.

Yes, I believe you are correct. Thanks for replying!

well, this is just an example that I cooked up. I'm trying to pre-render some images to blit during the display process, and this was just a test to figure out how to do it. There must be something simple that I'm missing here!

Java Game APIs & Engines / Java 2D / Drawing to off-screen buffer

on: 2003-02-07 21:44:03

Can anyone tell me why this code puts a white rectangle on the screen as opposed to a red one? There is something simple that I'm missing.

Also, is my second call to getDefaultConfiguration necessary?
