The Stellar Game Engine ("SGE") is a free 2-D game engine for Python. It is designed to make game development easier and faster, and it accomplishes this by doing a number of things for you, including window resizing, split-screen, collision detection, delta timing, and more.

 

The SGE is free/libre software, released under the GNU Lesser General Public License. The documentation has been released to the public domain via CC0.

 

The SGE is currently in beta, meaning it's basically done, but hasn't been thoroughly tested. Please help me push it out of the beta phase by using it and reporting any bugs you find. smile.png

 

SGE homepage: http://stellarengine.nongnu.org

 

All comments are welcome. smile.png

Is this engine the same as this? If not this could lead to confusion. happy.png (I guess yes by the way because it seems really a lot like GameMaker.)

 

One hint is maybe to post the source on Github, this allows for easier collaboration and people can easily look through the code like they're used too. smile.png

 

The engine looks pretty good. I haven't done a lot with Python myself, but I liked GameMaker. GameMaker has, however, a lot of shortcomings. Some of them are speed and choice of language, this really looks like it's going to be an improved version. Nice!

"Alternative implementations using Pyglet and/or PySDL2 as a backend will be developed in the future"

I think it will be interesting. Also well would have a simple level editor.

Yes, that's an old page related to it. The SGE started out as something for Stellar, but Emilio, the developer of Stellar, stopped developing it, so I've continued with the SGE as its own separate project.

I used to develop it on GitHub (actually, the old repository still exists here), but I gradually moved to Savannah for philosophical reasons (Savannah is closer to me philosophically) and technical reasons (Savannah has more stuff than GitHub).

 

Looking through the code is really not much different with Savannah; just go here and you can see everything.

 

 

Also well would have a simple level editor.

 

Just to point out: I stopped writing a level editor a couple releases ago. It was too slow and unenjoyable for me, and I couldn't tell if it was even worth it (mostly because I wasn't planning on using it, and ENIGMA seems to be doing well these days). However, if someone wants to step up and make a level editor or even a full IDE, it would certainly be appreciated, and I would be glad to help with it.

Savannah looks older... huh.png (Probably my generation...)

 

But I wonder what you mean with more stuff than GitHub? GitHub allows for easy pull requests and a lot of other features.

Maybe it would be better if he, or somebody else, changes that page? Especially since it comes up third on Google when you search for Stellar Game Engine. wink.png

Mostly the more advanced bug tracker, the web hosting, and the file hosting. I think GitHub has basically closed the gap now, but the main reason I use Savannah instead of GitHub is the philosophical one.

 

I would commit to both the Savannah repo and a GitHub repo if I thought it beneficial, but there were never many contributions even when GitHub was the main repo (and the few there were mostly just corrected small typos). Besides, the main thing I could use help with is testing (people putting the engine to use and reporting bugs), not development.

Huh, that's odd. I guess I'll have to do something about that, then...

 

EDIT: That page now points to the SGE homepage. That should fix the problem.

I haven't started on that and won't start on it for a while (if at all; given the rate of development Pyglet seems to have, it seems PySDL2 has more of a future). Is there any particular reason you want to wait for a version of the SGE that uses Pyglet? Keep in mind that it would be compatible with the Pygame SGE; it's the same API.

wrote in a personal, please check your incoming

 

PS

as alternative may be Allegro backend?

It's possible. I probably won't do an Allegro one (unless I become interested in it at some point), but if you want to make an Allegro version, you can do so. In the releases directory, there's a download called "sge-spec". This is basically the template I used to develop the Pygame SGE, containing the basic structure and docstrings that explain all the functionality. All that needs to be done is for the functionality to be added and for a license to be chosen and applied.
