I’ve added a pause, press P or PAUSE to pause the game. I had some problems with PAUSE-key in Windows, thus P also works. The player light toggle is now behind O-key. 
Oh, no need to worry about the FPS dropping down when paused, as the game starts sleeping so the FPS drop is normal.
This time I compiled the sources using javac instead of Eclipse compiler.
Kevin: Could you try again? It’s highly unlikely it works any better, though…
Sorry but I can’t find the log file, where did you save it?
APPDATA\platformer\engine.log on Windows, HOME\.platformer\engine.log on Linux and others (HOME is your home directory, like /home/username/ in Linux).
I did a search for .platformer
and I got nothing 
it runs slower now though.
Note that on Windows the dir doesn’t have a dot in its name…
Windows 7 Beta

abirmingham: Thanks.
You didn’t post the whole log, so I have to guess, but do you happen to have Ati GPU? A friend of mine tested a much older version of this engine, and got that same OpenGL error on Radeon 9600 Pro. He had pretty old drivers, updating did wonders in that case: the crash didn’t happen anymore and driver support provided FBOs and PBuffers, both of which were not supported in the old drivers. Perhaps you could update yours, if it isn’t too much trouble.

It works but I have no sound
sorry logs was quite huge I should have post both start & end …
I got an ATI X800, I ll try to update drivers but I did it recently.
You mean the music doesn’t play when you press M? There is not actually any sounds yet, apart from the music test piece…

Finally someone with a Mac, thank you! 8) Seems that the window icon code fails, I’ll have to investigate.
Performance seems to vary a lot between different Intel GMA models. On my laptop the game runs mostly at 60 fps (except the shaders don’t work, so it only does lighting). If you disable the bloom (press B), you should get a nice speed increase - judging from the profiler results almost 60% of rendering time was spent on the bloom shader…
Edit: Ok, seems that Display.setIcon() always returns 0 on Mac OS X… No icons for Mac then.

That’s entirely possible, since Mac windows never have icons You should supply an application icon though, you can set it either in the Application Bundle when you distribute your stuff (search Apple’s site) or in the command line add -Xdock:icon=
And after I pressed B the framerate went up to about 58-59.
Yep, I’ll keep this in mind for later. Thanks again!
I’m on my notebook right now.

I get this error, while starting up the game:
“An error occured and the game will exit:
Exception: org.lwjgl.opengl.OpenGLException: Invalid value (1281)”
I may have solved this problem… Could you try this version, it has some debug traces to help me narrow down the problem – and it doesn’t take the whole game down when the error occurs. It would help if you’d post the engine.log to me after you’ve tried it.
Actually it seems to work just fine now, everything
But I can’t find the engine.log =P
It’s in APPDATA\platformer\engine.log on Windows, HOME.platformer\engine.log on Linux and others (HOME is your home directory, like /home/username/ in Linux).
