Addendum

Also I'd like to point out that the abyss after the third screen is intentional, and represents the emptiness of life. You're slightly confused, none of it makes sense, and then you fall off a cliff. I don't like to reward players, I like to make them think and feel.

Ha, I'm looking forward to playing it! :)

Your packaging has a couple of issues on Linux. There's no python file to launch the game from. You've got run_game.exe but no run_game.py. I added "main()" to the end of main.py and then ran it with python src/main.py.

Also in your animation.py module you have data_path = "data\\char\\", which doesn't work on systems where the directory separator is not a backslash. Prefer os.path.join("data", "char", "")

The game crashes for me when it tries to unpickle your model. Here's what I get when I try it manually:

Looks like there is some trick to Squirtle as well. Tips appreciated, the screenshot is really attractive!

The game crashes for me as well.

Any help would be greatly appreciated!

Cosmologicon: If you "from animation import Keyframe, Joint" in main.py, you can get past that.

I had to edit settings.py and turn on fullscreen to get a usable display, though.

cyhawk, hidas: I didn't get your errors, so I can't help there. Sorry.

Here's a patch that fixes most of the above (you may have to apply it by hand because of the CRLF line-endings in the source, a "sed -ie 's/\r//' src/*.py" beforehand will help):

cyhawk: The problem was that GLints are int, not long, but int == long on i386, which is probably why the author didn't notice.

hidas: I also get your issue on my desktop (which uses the nouveau driver, and thus doesn't have great 3D support). I can work around it by not requesting multisample buffers, but that results in pretty broken graphics. It's totally unusable on my laptop with Intel graphics.

Thanks Stefanor, Jerith! After applying your fixes I got these exceptions:

I wonder how you didn't get them — these look like something that would never work on any system. Maybe your version of pyglet.gl leaks ctypes.cast and ctypes.pointer.
Anyway it works now. I can roll to the right and down the rabbit's hole!

Strangely I didn't have any trouble running this game.
