Problems running Env3d with Bluej

Hi all,

 

So I just recently discovered Env3d and thought I'd give it a try. I downloaded the most recent versions of BlueJ and Env3d. However, despite following the simple instructions provided with the lessons on this site, I can't get Env3d to run. I loaded the project in BlueJ, created the class, created a new object, but when I go to the Tools menu and click "Start Env3d", absolutely nothing happens. Env3d is listed as one of the extensions and the directory seems right. Both BlueJ and Env3d are up to date as far as I'm aware, so I'm not sure what the issue would be. If it were a graphics driver, I would assume it would at least attempt to start up and then either give me a black screen or lock up. I have a Sony Vaio with Windows 7 and to my knowledge the drivers are all up to date.

 

Any help would be much appreciated! 

Thanks!

Hi there, welcome to the site!

 

A couple of things you can try:

1)  If you haven't tried it already, try the "stable" version of env3d -- it is currently more compatible with older hardware.

2) Take a look at the BlueJ debug log file.  You can find the file location under "About" dialog box in BlueJ.  Post the content of the file here so I can help you debug it.

 

Thanks

Thanks!

Thanks Jason!

 

As it turns out, your tip on the BlueJ debug log was clutch, thanks. I really didn't think it was a hardware issue, and sure enough, when I checked the log I discovered the problem. I should have known to check that right away...rookie mistake I suppose, lol. BlueJ couldn't find lwjgl.dll, which was an easy fix. It all seems to be running just fine now, thanks.

 

I appreciate the tips, thanks,

Glad it's working now. I'm wondering what your solution was in-case someone else has the issue and checks back here.

 

Was lwjgl missing from the +libs folder and did you just extract the env3d_template folder again?

My apologies for the slow reply, I didn't check this for a while.

 

I suppose by default BlueJ didn't know where to look for the lwjgl.dll so it was trying to find it in its own program folder, which is what I discovered when I checked the log. The path I chose was to simply copy/paste the lwjgl.dll from the Env3D folder into my BlueJ folder, so when BlueJ looked for it, it was right there. Easy fix for me, although I'm sure there are other ways to go about that.

No worries.   Hmm, I wonder

No worries.

 

Hmm, I wonder why it wasn't reading from the env folder. Typically env3d's used by extracting the env_template folder and creating a project using that. BlueJ automatically sees the folder as a being a BlueJ project and, behind the scenes, env3d works its magic and integrates itself with the IDE (giving you options like Run env3d).
