Autumn Lisp Game Jam 2025 Starts in 8 Days

[pixel...@gmail.com]

Looks like the Autumn Lisp Game Jam is coming up shortly in 8 days.
I used the Spring Lisp Game Jam as an excuse to get some recognition for Medley back in '23. I had good intentions but my packaging and understanding was still very limited at the time. I feel I've got a stronger command now. 

I don't know if anyone else is interested in this kind of thing, but it is a low pressure celebration rather than a competition. A game can be as simple as something like a word search or sudoku generator. Or a full fledged action game like some of the Medley games like Pacman, Missile Command, etc. Or course, novel concepts are most appreciated.

I might try again this year.
It'd be excellent exposure for Medley.
A couple of InterLisp entries by us might raise and eyebrow or two. :)

I'll pass on this as I'm too slow a coder for the jam's timeline, I expect a busy-isher schedule around that time, and I've never been into gaming. But I'll support your Team Medley entry any way I can.

That said, last year I entered the RetroChallenge with a Medley project.

I have a Rubik cube solver program implemented in lisp.

Unfortunately the lisp implements a rule-based language

and the solver is written in rules in that language so it is

quite a tower; building a bulldozer to level an anthill :-)

This is a hangover from my work in Expert Systems which,

as we all know, was destined to take over the AI world :-)

Given the flow of AI history perhaps the next great AI release

should be named Ozymandias :-)

Tim

I met a traveller from an antique land
Who said: Two vast and trunkless legs of stone
Stand in the desart.^[d] Near them, on the sand,
Half sunk, a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them and the heart that fed:
And on the pedestal these words appear:
"My name is Ozymandias, King of Kings:
Look on my works, ye Mighty, and despair!"
No thing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.

— Percy Shelley, "Ozymandias", 1819 edition

Paolo, that's perfectly understandable. Nice contribution on your blog!

Tim, they *do* allow prior libraries and "engines" which is a nice option.

They have a rule about no AI generated code but the spirit of that rule is to prevent ChatGPT making games. That sounds very impressive though and would definitely be cool to show off in any context! The world needs more education in classic AI.

So I think really anybody can use prior frameworks but the core game or amusement itself just needs to be built at the time of the jam.

I think the slam dunk we really have though with Medley is that we can give them a source code file and they can run those on the online VM (I think there's an option to upload Source if I remember correctly). Its a sneaky way to get people ON the machine. :) One of the biggest stumbling blocks I've had in the past is people having to get an install correct for something like Guile or SBCL.

I have a simple idea for mine that is probably suitable... 

[Paolo Amoroso]

If one has a Medley Online account, uploading a file involves clicking on the IMPORT/EXPORT button, then clicking on the up arrow icon (Upload) in the sidebar at the top right of the file manager.

From an accountless guest session one needs to click on the Open File Manager icon of the noVNC's sidebar (second icon from the top), then do as described above for uploading to the file manager.

Find a set of differential equations in 3D that have only one solution.

Make each diffeq mean something, e.g. how must wheat is grown.

Make another diffeq mean population growth, etc.

Now you have the makings of Hammurabi, a text-based video game

Tim, 

There have been some textual games in the past but that sounds like something unique! I'd say give it a go if you find it interesting. I think you can even enter up until the last day so it's very low risk.

I'm going to probably do a smaller puzzle game based on the Hungarian Rings. The nice thing about that is once I get the movement programmed in, shuffling the puzzle for the player becomes randomly jumping between the rings and triggering action N many times until shuffled-enough-p is reached. I had wanted to try that puzzle for some time.

Right now I have to do a little ground work and learn the best way to get a mouse click relative to the window's display stream (DSP) and not do oddball hacks like I did last time subtracting off the window borders and such.

Loading /external/ images would be nice too.

They can then be saved in the internal image format and bundled.

If that's not easily feasible I have some procedural alternatives in mind that can be written to a bitmap.

Thankfully, I've got an 8 day buffer before it kicks off.

I spent a good chunk of today just kind of thinking up the data structures needed.

I think there's also a card deck somewhere in there. A card game could be made from the blackjack(?) demo In LispUsers. Perhaps the original aithor owns those card graphics... As somebody who's an artist, I'm very careful about art ownership.
