Anyone want to help test my Voxel Editor?

I made a voxel editor so that my friend could create models for a game I’m making. It works fine on my Windows 7 64 bit machine, and my Ubuntu 32 bit, but it doesn’t work on my friends computer. It just shows a blank applet, and he doesn’t know how to get a stack trace. Could someone see if they get the same screen, and if so, give me a stack trace? Thanks!

You can’t save yet, and there’s only 9 colors (It’s just a test version.)
Controls:
W,A,S,D - Move cursor around horizontally.
Q - Move cursor down.
E - Move cursor up.
R - Place voxel at cursor
F - Delete voxel at cursor
1 through 9 - Change cursor color

Your program worked fine for me. I’m on Windows XP-Home, Java 6.

Maybe you or your friend already know about this, but on Windows machines, one can go to the Control Panel and open the Java utility, and go to the Advanced tab. That has the spot to make the Java Console visible, to get stack traces.

Thanks, philfrei. I told my friend that, but he said he didn’t want to mess with it. He’s always afraid he’s going to break his computer. Otherwise, I would’ve gone over and figured out the problem myself (He lives next door.)

works for me. win7, 64 bit. what OS is your friend using?

it works fine for me, windows xp, java 1.6.0_23 .

About the editor itself, I suggest placing the keys for adding/removing voxel on the right side of the keyboard, since most people have at least two hands and the left one is already busy moving the cursor.

Works fine here with Ubuntu 10.10, however you failed to mention that arrow keys moves and rotates the camera.
