Unbeatable AI Ruins My Game

one hard thing to consider about ai enemies is that to keep them fun you often need to factor in human reaction times and make the ai have a 250ms input delay to counteract that. but also make it think 250ms ahead *pulls hair out

You should re-train the neural network, but start it fighting against the 'unbeatable ai'.

I think it would have be fun to include a match of the final ai playing against itself

Is it just me or is the Jonas crazy factor through the roof in this video... LOVE IT XD

It's actually really wholesome for you to get sponsored by Gamemaker!

I think the first AI approach would have worked just fine, the problem was that the game was designed so that not loosing was the only goal of the ai, and it technically didn't lose by not playing. This is a very classic senario when you work with 'real' AIs. You you might consider some form of reward/punishment system that is tied into acceleration. :)

I seriously love how you can keep making such high quality entertaining content while slowly descending into madness lmao. Huge fan of your work

I think one part of why the trained AI failed is because it trained against itself right. Because each level of bot only needed to become a little better than the previous bot, the growth stopped going so fast at some point. maybe the bots "learned by heart" a strategy that was flawed and then only improved on that because all the previous bots use it. like the bot can beat its enemy only if its a worse version of itself, which also uses the flawed method. What if you put an AI to train against your hardcoded AI, that you know is better than you?

I guess the neural network brain didn't work because it had no idea what the hell was going on! Besides self position, it should get the enemy's position as well as "distance to circle" so that it would learn how effectively it just pushed the enemy to its death. Also, "elapsed time" is another input that will help it learn about the shrinking circle much faster. Poor thing was playing with its eyes closed!

Would be interesting to see how the AI would do with some noise on it's output or if it had human limits on the input

I’m convinced that Jonas records and keeps a bunch of stock footage of him doing random silly things so that he can use it in videos when appropriate

15:01 that's frickung genius! GameMaker really chose the best man to sponsor

I absolutely love your channel. Such fun energy, useful insight and advice, great editing, and awesome shoutouts to others

Love your videos. Always excited to sit down and watch your production-level content. Keep it up, you're a bigger insperation than you know.

Jonas, I finished playing your game Will You Snail around December last year, and I just want to say that I love that game so much. I love the ending, secrets soundtrack, and so much more! - You’re game is a work of art. I even bought the soundtrack! Just wanted to say thanks for everything Jonas & keep up the good work with your video & games!

I didn't knew you could actually train AI in GameMaker. Congrats on being sponsored by them! :D

I have been waiting for your videos! finally here:)

Ohhhh yes! The jonas-style devlogs are returning! So glad

Glad you got sponsored. Hope to see more content and games！！！

Love the Intro 😂 props to your video making skills btw.!

I'm thinking of how to make the opening more interesting. Which should give you a fighting chance against the unbeatable AI. Instead of the straight vertical line, there could be - slanted, wavy, pointy criss cross, outside borders are solid with no center line, etc. also, the arena could be of different shapes as well. One last - how about a one time use power up? Like an instantaneous boost. But of course, use it wrong and you lose, still.

Best sponsor integration of any video on RU-vid, and always will be. You just plugged your sponsor _and_ made people excited to download their engine. Wow. Best sponsorship decision YoYo Games ever made.

Pretty good way to do a sponsor lol, you make a fun game, open source it but only of that engine of course

6:22 he’s evolving, just backwards.

Great video :) Only thing i missed: Final hand coded AI vs itself.

Very helpful perspectives. Thank youuuuuu!

This is such a good game😮. Make another 2-3 vids on polishing this game and release it! This is a really amazing game i am so surprised. I really wish for this to be polished to be made into a full standalone game

Awesome to see you made the game public domain, I wonder if people'll make gamemodes where there's items like bumpers you can place down, or a parry that if timed well, knocks the other back. Or a good old reverse controls. Clearly this game needs a 100 player battle royale too

I love this video. It's just a breath of fresh air to see an old AI method being used again. Also the game looks and sounds so nice I wanna play it

I've had this idea for a while but you've beat me to it, I will try to use the game files and try my best to recreate it in unity. Thanks a lot for sharing them.

Jonas is your typical weird neighbor kid... and I love it!

After your last video... I needed something like that! :) Thank you! You made a very good job with this sponsorship and actually, I'm pretty happy that your neural network created a worse AI than what you were able to code yourself haha! :Đ

video production is brilliant really enjoyable.

How big is the neural net you're using?

That reminds me of a quote I've heard, not sure where it was: "The goal isn't too create an AI that plays as well as possible, but to create something that's interesting for a human to poke at."

The hit new game “Will You Ball?”

Jonas: *makes game public domain* Viewers: ooh free game idea!

Sehr cooles Video. Wie immer sehr lustig. Ich habe mich die ganze Zeit gewundert warum die AI so schlecht performt und dann hast du erwähnt, dass du nur 20 neuronen genutzt hast 😬. Nein aber ernsthaft, nicht böse gemeint, aber für ein Spiel dieser Art solltest du deutlich mehr Neuronen Nutzen. Mit modernen Methoden braucht man auch nicht mehr so sehr vor overfitting auf der Hut sein, zumindest wenn man beim Training auf viel Varianz achtet. Für Spiele solcher Art eignet sich aber Reinforcement Learning meist tatsächlich am besten.

Nice editing bro

Great attempt and video. I've dabbled in GameMaker AI and my approach was to establish different 'moods' for the bots; i.e. aggressive, passive and mix of the two. I then set randomised alarms to alternate between the different moods. I had 5 bots V 1 human. It made for some decent results. ...needs work though 😀

Random potential ideas: A dash mechanic randomly spawning powerups a gun cheering into your mic to power up your ball mines make the map a bowl (gravity towards the center) multiple maps jumping burst meter hitstun slime! control point/zone capture the flag mode soccer a giant unstoppable angry moon that is going to crash into your home and obliterate everything hats!

I really want to see another video on the king builds a kingdom game... plz :)

Fantastic! Game maker having machine learning is wild to me because last time I used it was probably 2013. 😂

This is a certified Jonas moment

Best part of Hardcoded AI is that, they can be made impossible to win, except for some specific game mechanics like chess and GO.

Please do a showcase of other people's take on this game! Adding fixed obstacles or bumpers to this game would be cool. Like competitive pinball.

Really cool game! I assume the sounds are allowed to be used in other engines?

Man, this video takes me back to when I was a kid also and also using Game Maker. Back then it was a Game maker 6.1. Used to make some little games etc., mostly using just the blocks and occasional pre-made script for specific purpose. I also tried making some small games with students at the middle school I work at. Wow that must have been maybe 10 years ago already.

Good game, you made beyblade! but in the spirit of user friendliness the black can be a bit hard to see on the dark green

Interesting video Jonas. I think the problem may be rather than making the AI sort of smart and defensive you could have the AI move in a random direction with stipulations such as it will move randomly but if you are in a radius near by the percentage increases that it will move towards you and then back to random. The same method could be used when the AI fails and goes off the edge by it's self and that happens a lot more at first but the more you play the less often that happens while still a very slow increase of it's agression towards you and have it know it's during the edge at times so it can start to evade more often and progressively. At some point adding obstacles that do funny or interesting things to avoid or just barriers might be a good change so you won't require the temporary barrier. And theoretically if the AI moves faster than you but hits you with a bit less force due to you having a lower mass than it then it's easier to trick at first.

I don't think the ai ruined it, i think you add a timer and now it is a survival game 👍

The game itself reminds me of bumper balls from Mario party. That was my favorite minigame out of the bunch. It's like your game, except with 4 players, characters standing on balls bumping into each other. 4 playes introduces a lot of chaos that makes it much more fun, like you can get speed off of one person bumping you to launch into another player to knock them off. It often ended with 2 players going until time ends (it used a timer instead of shrinking the arena -- shrinking is better, because it always determines a winner). The unbeatable AI ruining a game reminds my of the seventh guest. It was a game where you explore a mansion and complete a bunch of puzzles. Except one was a game you played against the computer. It was turn based, I forget the rules exactly, you eventually filled the board, could flip each others pieces, and whoever had the most at the end wins. I spend hours trying to beat it, felt like I massively improved my strategy, but never stood a chance. Every time I thought I had a sure winning strategy, the computer ALWAYS countered perfectly, and I'm not sure if it was even possible.

Sorry a part of me ruined your game Jonas

Help plz! How can do parallax my dots background in Filter/Effect Layer ?

Wow, I did this exact thing in GMS1.4 back in 2020! I planned to make it a boss rush where each opponent has different weights/abilities/etc so that they're forced to occasionally deviate from the unbeatable state machine

i think i saw a mouth harp in sfx making, tbh, that's sick

this felt like the amoungus potion video but with AI

What's kinda missing in the video is a basic outline of the strategies you implemented for the final ai.

Jonas voices are something else.

Hi Jonas! Can i ask what microphone were you using to capture the sound effects?

:0 This game is the exact game I made on scratch ages ago! I even made an AI for it and everything!

Dammnnnn the ai was really just bullying you at the 😂😂

inputs I see relevant - position & current velocity for both balls - match time (or how long until the gate opens) - table size outputs - applied force vector which leaves me curious how big the neural network was - how many layers and neurons? might also be worth pitting it against the hand coded, non-trivial AI, so that it has to work against something at least somewhat more capable then "standing still" and "move directly at" for base AIs and only things that could defeat those. or even adding something like "move to the middle and circle around it" as an AI... as you said, you may have hit a local minima as there wasn't enough variety in the strategies it had to defeat.

"I'm evolving in the wrong direction" xD

This criteria fits a game jam that took place around when you made this video, was it for that?

Crazy idea: make a hard coded op AI And then train AI against it 😂❤

Hmm it seems like your AI is basically a live-TAS. Thing is that it does things with unrealistic inputs, ergo it doesn't have the same capability set a human has since it can completely change the input direction every single frame. It would be interesting to see if it was modified so that it can only do so as fast as a human realistically could in real time.

ideas to make AI better: -train separate populations of the AI, like how different types of life come from being separated/isolated, then occasionally make them fight against each other -more nodes. more layers. more everything -more inputs. Even if they are redundant, they may help the AI in unexpected ways. -short-term memory. If an AI can remember what it's doing, it can possibly create more advanced strategies.

5 vs 4 was a battle for the ages 8:46

Mario Party bumper balls

I think reinforcement learning would be the best way to do it meaning the AI has to train based off of limits that you set it, but that would require a stupid load of matrix multiplication, and if you manage to do that in GameMaker, hats off to you. Personally though I would've just tried to write some compute shader in unity to handle the matrix multiplication. There's the unity mlagents package as well, which can do the reinforcement learning, but that's probably too large of a project to be feasible.

reminds me of the game "spellsworn" (which is based on the wc3 map "warlock")

wouldn't it work to have the nueral network play against the final hardcoded ai in its training?

One of those ML models that learns to mimic an expert (aka you) might work to make a standard to evolve against, or even to directly play against

this gets me thinking, if you put an ALMOST unbeatable AI as a final boss in a souls-lite with only one weakness that's an oversight in it's hitboxes, meaning you need to just survive until you can get to the weak spot, and the hard mode randomizes the weak spot each time you attack.

wait i remember that game, it was called sumo balls and was up to 3 players and 3 AI

can you make a build for it?

Squid lives throughout the games

I would buy this on steam if it would have online multiplayer

What if you removed fitness for every second the trained ai takes to win? Maybe that'll make it not wait in the center

I like how you trained the balls to become a team. You may want to reward the AI with more points when it wins faster, also you AI found a spot where it no longer needed to grow according to the rules you gave it. You may want to try mutations in some generations.

this is a great example of why not to just rely on a 'magical AI black box' and how actual algorithms, where you know what they'll do, and can easily tweak them are often better, and more reliable

The game reminds me of one of my favorite mini-games in the first Mario Party. There it was a lot of fun also because there were 4 players, making it hard to track everything

Why ? You will zee why! : ) Love your content !!!!

Jonas you are a great guy.

I have a multiplayer idea for will you snAIl: one controlls the snail and the other player controlls squid the snake has to dodge spikes that the opponent. the opponent trys to prevemt that the player goes to the goal!

Congratulations! You just made Bumper balls from Mario Party with a Master AI level!

The last time Jonas tried to make a hit game with an ai it did not go well.

would love to see this game made with an AI that learns from your play type and evolves to match the opposite play type for example: if your aggressive, it will play defensively and lure you to your own fall if your defensive and attempt to lure the AI to the edge, it will start to play aggressively The tricky part is. that when you first play the AI it should be very bad, and only get better over time. so if you change your strategy, you can beat it for another 2 - 3 games, this way the AI would encourage you to find new strategies and play types, since its NOT unbeatable

Distracting squid to kill her

jonas next indie game? xD

Jonas recreates Fusion Frenzy's Sumo mode (and Hard AI) ;)

Am I crazy or did the final AI just ignore the lose condition? You knocked it out twice and then it hovered outside of the circle at the end...

i love your vids!

A new Jonas video to watch instead of working on my game!? Don't mind if I do!

This is literally a Mario party NDS minigame

please release as a playable version on itch or something 🙏

higher-end chess bots be like:

Damn, I would love to play it but don't wanna build it myself. Could you release a version that I could just download and play?
