We can do more nuanced things too! For this, I set up Pixie's goal so it was to make the player move around a lot, but not make the game much harder in the process. It created this spawned of very slow-moving obstacles, so they're easy to dodge but make you run around a lot more.

This can result in quite... unusual suggestions. Part of the fun with working with Pixie was seeing this kind of thing. All the examples in the paper are run on games I didn't write, so it's all new codebases Pixie wasn't designed for!

So for example, here's an implementation of Breakout. We'd like to make a powerup to make it easier for the player to win. After a while, Pixie came up with this - the ball gets bigger on each bounce. Watch what happens... a very broken idea, but one that's kind of fun and unexpected.

Pixie requires just a little bit of guidance to get going: some annotations on your code, an example game scene it can load to test, and a goal to aim for (we express this as a numeric goal, like maximising the player's score). Then it tries lots of ideas to see what works!

New Paper: Pixie: Code-Level Mechanic Generation for Game Designers. How do you connect automatic game design to real games? Pixie is a mechanic generation system for Unity games, as an example framework for how to build AGD systems into real game platforms.

This paper includes, among other things, an attempt to define a subset of procedural generation work: "procedural gameplay systems" (not my best term-coining, I'll admit). I report on a survey of players and developers on what we mean when we talk about "games with procedural generation in".

New Paper: Game Design is Generative Design. Designing a procedural generator and designing a game share a lot of skills, problems and philosophies, even if we think of them as distinct. I try to connect them here, for good!

What is speedrunning? Why is it interesting for AI researchers? What fun, silly, playful things could we make together?

AIIDE has a “test of time” paper award now - for papers from the past that has a long impact. I really love this, it’s something a few other conferences do and I think it’s an excellent way to reflect on the past.

The last EXAG talk is about writing a neural network that runs on an original NES. This is a perfect way to finish the workshop. Incredible.

I'm having such a lovely time at #aiide and it's such a well-run conference so far, in a great location. It made it feel all the more nice to talk about community, with a community that means so much to me. Here's to EXAG 2035!

Bitterly ironic quote here from a 2023 article about the Future Class situation by Younès, whose name is absent from the both the articles I've seen today and the viral social media posturing by people who should know better.

I found an old photo of one of the first Feral Vector event schedules today while rifling through old backups. I believe this is from before the renaming?

You can get it in a bundle with Unfair Flips right now and it’s basically this joke but for game design school

Trying to imagine the definition of center-left you’d need for this to be true, very funny tweet though, good work.
