Mac bug? Or just his machine?

[elias4444]

Here's the output that gregorypierce was kind enough to send me. I'm not quite sure how to handle this one. It could be happening because I call the object from a Swing-based menu (the menu is where I let them setup their display options and the like). It works fine on Windows and Linux however.

Fixed (as stated in gregorys thread). Be careful with calling GL from the AWT thread.

Be careful with calling GL from the AWT thread.

It seems to make sense for creating a "pre-launch" window however (it's much easier on a system to set the resolution, vsync, etc, before the OpenGL window is created). It gets a little tricky when trying to do it "in-game" (you have to reload all your textures for the new resolution when they switch, and destroy/recreate the OpenGL window on the fly). Is there a better way you would recommend?

In the meantime however, THANK YOU for the fix!!!!  

[elias]

You don't have to reload textures, just use Display.setFullscreen() and Display.setDisplayMode() (keep the bit depth though).

- elias

[elias4444]

If you switch the displaymode (via setDisplayMode) will it automatically switch for you?

Also, if I understand you correctly, one shouldn't switch the color mode then?

[elias4444]

BTW, I tried that download link for the updates, but it comes up empty.

[elias]

Yes, you've understood it correctly. The newest link is:

I've installed the new libraries... now, on all platforms (Mac, Windows, Linux), the OpenGL window just flashes open and then immediately closes.

[elias]

And then what? Exceptions? Native crashes? Or does the program really just continue with no window open?

- elias

[elias4444]

I've been trying to find out what's going on... I'm not getting any console messages. The java process just sits there as if it's waiting for something.

Maybe I should be a good little programmer and do my menu in-game.  :?:

[elias]

Try sending it a QUIT signal to get it to dump the current threads. It sounds like a deadlock.

Under linux you send it by pressing ctrl-\ in the console)

[elias]

There are some minor API changes in the new build, so did you re-compile your game with the new lib too or did you just try an existing version with replaced libs?

- elias

[elias4444]

I just swapped out the files actually. Are these going to be changes for the next version official as well? Because it looks like it's the keyboard.enablebuffer call.

Here's the output from the QUIT:

P.S. I love how I had to use Linux to get the info for you.  

[elias]

Yes. Just remove that call, since it's done automatically for you. Same with the Keyboard.enableTranslation() call (if you use that). To be sure, recompile the whole game against the new lib.
