Hi guys,



When trying to run an empty implementation of BaseGame or FixedFramerateGame, I get the following:

I can't understand the reason... All I can say is that I have the latest (and most stable) release of LWJGL, I got it yesterday from their website. Does jME uses an older release?

Sorry if this post is not meant for these forums :/

Well, a team member got the jme jars for our project (jme.jar, jme-ui.jar and a few others). It's all working fine with LWJGL .97.

Thanks for the help and the attention provided! Nice community, this one!

No, I just got the .jar from the jME's project page at java.net, and the LWJGL .jar separetely.

Did you compile jME from cvs source?  if so, .97 lwjgl should work fine.

5

That would be why.  The jar is from the beginning of the year, thus it is compatible with lwjgl of the same time frame.  I believe that was .94

6

Is downloading the CVS code the only means of getting the current stable jME release? Can I get an updated .jar file without having to download your java.net's code and compile it? I would like to avoid that, if possible.

I'd just like to note that older LWJGL versions are still available on:

Yes. However there is a great guide on how to do this.

But it's not quite "stable". I mean, it is the development version.

True…

That’s the reason why I didn’t want to grab it from CVS :smiley:

I’m also a java.net user, I have a small project in their game forge. So downloading the code from their CVS is no big deal, but I would like to stick to a “stable” version, compatible with LWJGL .97. I know that I might be asking for too much :D, but if anyone could provide me a more “updated” .jar of the jME (or show me where to find it), I would appreciate it. My e-mail is this one: rodrigogh@brturbo.com.br



Thanks for the help guys!
