OpenJK licencing question


Recommended Posts

Hello, I'm new to forum. I love playing Jedi Knight games. I'm also 3d artist, I have my own story ideas and I want to create own game and release on Steam. But I'm not programmer so I was looking for ready engine with good fight system.

If OpenJK is open-source, can I use engine for my game (replace models, textures, sounds etc.)?

I read that engine was open-sourced by Lucasfilm, but I read also that they deleted code, and engine is available because fans save it.

PS. Sorry for bad English.

The only real answer is: talk to your lawyer if/when you're serious about releasing anything, especially commercially. No one on the internet can really give you the legal advice you need.
That being said, my advice is steer clear.

My other advice is start with ioquake3 (same engine JK2+JKA are built on) and work from there, to avoid "Star Wars" (read: Disney and their infinite financial + legal resources) coming to bite you. I'd also steer clear of "laser swords" and "magic" which could be reasonably argued by lawyers to no end.
You'll need a lot of coding experience either way you go.

JKA is specifically a legal grey area, given the source was pulled and a gag order given by Our Great Overlords specifically over licensing/legality concerns.

There are a few other threads discussing this and similar ideas. Quick search showed these will be of interest:

from my understanding the engine is open source but part of the code wasn't i don't know which part since i'm no coder and that was the reason of the tookdown since the coder complained,the problematic code was the bink video decoder from rad game tools which was on the source.

Just remember one thing even if open sourced problem is textures and models aren't and since most mods are derivative works you see the problem.

Normally accepted making everything from scratch from maps to player models not using something as base and changing it accordign to what you want sadly most mods start with a derivative of X model and use the skeleton as base and animations.

I was also wondering about the same thing. I've started work on a project to make an original game based on JKA's framework, using assets made by me and some royalty free models. However, I'm unsure on the legality of this whole thing.

you would need to remove everything from video decoding to anything that uses rad game tools in the source of OpenJK sadly requires coding and isn't as simple

Well to know more about this read the reason of why was removed https://www.kotaku.com.au/2013/04/just-like-that-jedi-knight-code-has-been-removed-from-sourceforge/

Also lucasfilm don't exist anyomore so there is no worry about them.

The answer @Raz0r gave is the only answer, really. Even though OpenJK is open source, it was a result of the source code being released without Lucasfilm's approval, so it's risky.

You're better off making it a mod of JKA, use OpenJK as a base, and doing as much work as you can to make it seem like a new game while still requiring JKA's assets to be installed/purchased. The game is cheap nowadays anyway, and anyone interested in your game will probably already have it in their Steam library anyway.

Nobody here can stop you though, if you want to risk it, go for it. But the moment your game gets any traction and articles are written on it, the moment Lucasfilm will catch wind and possibly do something about it.
