AI & Games Jam: 2021
It’s time for the first ever AI & Games Jam. Every word in the title is something near and dear to me, AI, Games, and Jam. This post is going to be updated a few times as I work my way through the weeklong jam. I’ll begin with the cursory ideas, some prototypes, and eventually will clean up the whole thing and make it into a coherent narrative.
First, let’s ideate:
The Jam is judged on three principle areas, originality, presentation, and fun. There is a theme: “Breaking the Rules”.
- Initial impulse was a cliche: a detective that doesn’t play by the rules and wants to solve some kind of case by interviewing subjects. Lets me work in chatbots, which I know and love, and would probably score highly on originality, but probably wouldn’t be too much fun.
- Maybe a Smash-TV knockoff where you play against an ever-evolving AI army that’s trained with reinforcement learning or NEAT. Gameplay wouldn’t be super original — shooter arenas are a dime a dozen, but how many actually evolve their AI as a difficulty mechanic.
- You are an ant in a colony tasked with finding resources, as ants do. While all the others are happily gathering their materials as directed by pheromones and swarm behaviors, you’re left to your own devices. Can you emulate an ant well enough to avoid being rejected by the colony?
- Papers, Please! but the Turing Test. You play a malware detector sitting on the edge of a network and need to talk to applications as they move past you: the firewall. Possibly really hard, but not impossible. Would be original, but perhaps not fun. High risk, because the core gameplay mechanic would revolve around an untested, possibly bad, chatbot system.
- Dream Explorer: move though a latent space trying to find someone’s dream. Fancy GAN — steer through 3D or 4D latent space to find a matching image. Low theme adherence.
- Crazy Self-Driving Taxi: Driving Sim where you break the rules of the road to get your pedestrian to their destination.
Day 1:
Most of this is predicated on chatbot systems. Those are fairly tricky, and integrating Torch with C# can be a mess. Even training a decent model in the given time could prove impossible. That means tonight, goal one has to be getting a steerable language model to run end-to-end. If I can’t do that in the next two hours, I have to fall back to the Smash-TV knockoff. Let’s get started.
End of Day 1 status:
Tried chat bots for an hour, decided it was too high risk, and went with the SmashTV approach. Movement and shooting:
Day 2:
I have from now (10:00AM) until 6:00 PM tonight to get my stuff done. After that I’ve got social and work obligations for the rest of the week, plus whatever time I can squeak out between 10:00PM and 11:00PM next week.
My initial impulse is that I’m not really liking the interaction between the theme and the game idea. There has to be a way to make the theme a _core_ of the mechanic and not just an afterthought. I’m thinking back to a game I tried making a while back, Terminus. The big hook of that game was the CPU and being able to program robots oneself. Hacking systems is pretty within the idea of breaking the rules, and the gameplay will be more novel. Going to take everything I have and just try to apply it here.
End of Day 2:
Well I’m pretty sure I focused on the wrong thing. I find it personally fun to program these tiny robots in assembly but once again I’m not sure how much anyone else is going to want to do this, and if we need a variety of creatures in the game then this may be time prohibitive. Really was hoping to have something more substantive by EOD today, but that’s life.
Day 3:
Didn’t get home until a little later. Worked on things for about an hour or so. Added some camera follow with smoothing and lookahead. Threw in a tileset that has collision. Need to get back to focusing on gameplay. At least I need to figure out a win and lose condition or something that resembles a mechanic. In hindsight, I really didn’t plan enough there.
Day 4:
A bit of a pivot. Again. I have a less nebulous idea about finishing. Didn’t even realize that I was forgetting about an end state until I started thinking about the “why” of the player’s actions. The new goal is to find your lost dog. That’s simple enough and lets me iteratively improve the game while always keeping a complete build.
Steps: first you just find the dog on the map. Add a win condition when the player is within range.
Bonus: add a ‘restricted’ area that the player needs to enter to find their dog. Open it using the hacking technique above OR finding a keycard in the map.
Bonus: chat bots to ask where the dog is.
Bonus: more curated level.
Bonus: random levels.
Bonus: dog moves around depending on hunger and thirst.
Day 5:
Had an unexpected opening in the evening to work on things. Made a bunch of procedurally generated people and gave them a bunch of waypoints around the map that they’d move between. There’s a bug in the pathfinding, though, and all of them seem to move to strange places. I also have the trigger for win, but haven’t done a screen with winning on it yet.
Day 7:
Didn’t have time to work on day six. Day seven was a bit of a frantic wrap up. Mostly wanted to get the game packaged and uploaded. Added the title screen and the final page, fixed the nav bug (relative position for movement target). I also had to draw the nav mesh separately and clear out all the navigations added to the tilemap because characters were getting stuck on the wall.
Closing Thoughts:
That was okay. In hindsight, I should have done something with more options to demo some fancy AI. If I could do it again I’d make a chess game were you can break a single rule (and have a piece move like a queen) once per game.
