Exciting to announce that the second edition of the PCGML textbook by Sam Snodgrass, Adam Summerville and myself is online! This version is a major update of the first, with a new chapter on GenAI and updates on the last two years of research.

Be sure to chat with @sebastianberns about this super cool work if you're at CHI this week! Had a lot of fun with this team looking into how human perceptions align (or don't) with common similarity measures used in PCG and other domains.

[Sebastian @sebastianberns]

This week, I am at #CHI2024 to present our latest paper. “Not All the Same: Understanding and Informing Similarity Estimation in Tile-Based Video Games” https://t.co/xSH6Vwupd9. Co-authors: @CIGbalance, Laurissa Tokarchuk, @SamPSnodgrass and @creativeEndvs.

[Sam Snodgrass @SamPSnodgrass]

@MatthewGuz @sgware Ah, you beat me to it :)

[Sam Snodgrass @SamPSnodgrass]

@sgware I would recommend checking out @KenneyNL's sprite packs. I think they mentioned they'll be moving some things to other non-Unity engines (Godot, Pico-8) in the future as well.

Tired of AI hype but interested in reading about how machine learning (generative AI if you like) can be used to generate content in games? Well do I have the book for you!

[Sam Snodgrass @SamPSnodgrass]

@JoINrbs I think there are a number of AI researchers who'd be happy to test this empirically (myself included)

[Matthew Guzdial @MatthewGuz]

New paper on Procedural Content Generation via Knowledge Transformation (PCG-KT) from @riffsircar, me, @SamPSnodgrass, @Autumnsburg, Tiago Machado, and @gillianmsmith. We propose a framework for transforming knowledge between domains, allowing for generation for unseen games!

Reminder that *today* is the last day to submit to the @ieee_cog call for Competitions.

The full call for competition proposals can be found here: https://t.co/PffiTZB7uN

Looking forward to seeing what everyone sends in!

[Sam Snodgrass @SamPSnodgrass]

From subtweet to published book in ~2 years? That's not a bad turnaround. A PCGML textbook now exists! I had a great time writing this with @MatthewGuz and @Autumnsburg And I'm really hoping this book helps bring more people into the field!

[Matthew Guzdial @MatthewGuz]

I’ve had to explain to a few students recently that there isn’t a PCGML textbook because the topic only coalesced ~4 years ago. But if any academic publishers want to pay @Autumnsburg, @SamPSnodgrass, and I to write a textbook I certainly wouldn’t say no.

@GalaxyKate Life lessons with Uramichi Oniisan is solid comedy about a 30ish year old who works on a kids television show and is just generally struggling with his life.

[Sam Snodgrass @SamPSnodgrass]

Well, well, well. Look who got a title bump. I'll still be bringing PCGML to game devs, and exploring new ways that PCGML can impact game design, and improve bots and testing. Now with some seniority sprinkled in! Looking forward to growing alongside @modl_ai in my new role

Last month we tried our first Twitter spaces and we are ready for round2 with @holmgard @risi1979 and @AIandGames
Listen to the experts argue about behavioural learning and it’s implication for Player bots in Video games.

Should have used this as the abstract to my dissertation.

[Sam Snodgrass @SamPSnodgrass]

@MatthewGuz @D_M_Gregory @mtrc Awh, thanks friend

[Sam Snodgrass @SamPSnodgrass]

@D_M_Gregory @mtrc A while back I also worked on level gen conditioned on path info (https://t.co/8EWG9OKzMh, https://t.co/UowJOlGiO0) We trained a Markov chain-based model on level details+paths then used paths as a condition while generating. @MatthewGuz's work compares against this approach too

[Sam Snodgrass @SamPSnodgrass]

@sysnet_ai Personally, I'm hoping for a Fast X, which they use for a major crossover event to finally bridge the DCU (Diesel cinematic universe). Show me Dom racing Riddick in spaceship you cowards!

[Sam Snodgrass @SamPSnodgrass]

@gillianmsmith That's amazing! Congratulations!
