Java games rock!

Pulled cvs last night...

making this call

1  
      canvas = Canvas3DWrapper.createStandalone(Canvas3DWrapper.OpenGLLayer.JOGL, Canvas3DWrapper.Resolution.RES_800X600, "Game");

public static ColorDepth getDefault()

                case JOGL:
                default:
                    return(B32);
            }
        }


why is a static lastUsedOGLLayer variable used when an explicit request for opengl was made

Thread [main] (Suspended (exception UnsatisfiedLinkError))   
   Sys.<clinit>() line: 82   
   Display.<clinit>() line: 103   
   CanvasUtilsLWJGL.getBestColorDepth() line: 22   
   Canvas3DWrapper$ColorDepth.getDefault() line: 164   
   Canvas3DWrapper.createStandalone(Canvas3DWrapper$OpenGLLayer, Canvas3DWrapper$Resolution, String) line: 680   
   Xith3DFrame.main(String[]) line: 147   

I am dying on some LWJGL thing even though I wanted opengl..

case LWJGL:
                    return(org.xith3d.render.canvas.utils.CanvasUtilsLWJGL.getBestColorDepth());

I need some more info. Do you want to use LWJGL? Or is Canvas3DWrapper choosing it by accident?

The static variable is used to define a default. The default "by default" is JOGL. But if you've once chosen LWJGL the default is switched to LWJGL. So when you create a Canvas3DWrapper without explictly selecting a specific OpenGLLayer after you created a first one, the second one is created with the new default OpenGLLayer. Is there something that annoys you with this behaviour? Maybe we can find a better one.
