AI Learns to Play SUIKA GAME 

In the original Suika game, two watermelons annihilate each other allowing for the possibility of an infinite score. Seems a little like making the game too easy, but making two watermelons is actually insanely hard for humans. I would love to see how far the AI can go with this new rule.

"It's like children, you gotta kill a couple to make an omelet" -Code Bullet, 2023

Realistically redeveloping suika isnt hard, but it's still impressive to do it so casually.

I love how code bullet invented nuclear bombs in a game about combining fruit

What code bullet doesn't realize @ 5:30 is he's literally modeled critical mass for nuclear explosions with fruit.

Plenty of people have identified the double watermelon effect wasn't right. The one that bothered me was the lose condition. It's not when a fallen fruit touches the held fruit, it's when any fallen fruit leaves the play area at all.

At 2:30 you were hoping you saved recently, but unity actually creates a temp save file each time you press play (located in temp file. Have to change file type to a .unity file). HOWEVER, unity also stupidly deletes this when you reopen the project. I always go and grab this file before reopening a crashed project. Can save a ton of time Also, really liked the video! I remade suika myself for a personal project, and it's really cool seeing you do it too ^^

4:05 I've never laughed so much at such a human reaction to computers being computers

5:35 Only Code Bullet could manage to program nuclear fission into Suika Game

So many people have pointed out that 2 watermelons annihilate each other, which would allow his AI to get an even better score. HOWEVER, in the actual game there are a few complications he didn't include. For one thing, the fruit hit boxes are NOT all circles. Grapes in particular have a very irregular hit box that causes them to be very annoying. Secondly, the fruits have different and odd weight values that can make them push other fruits around. Thirdly, it's actually impossible to drop larger fruit on the far sides, because they hit the lip of the cup and bounce inward. Finally, and most importantly, is Fruit SpaceX. In the actual game, when two fruit combine, they merge into each other, very rapidly. So rapidly that if a light fruit is sitting above the fusion in just the wrong way, that fruit can get launched out of the jar at escape velocity and it's game over. This kills so many runs, and all of these factors would make reaching that AI 2 watermelon goal a lot harder. All in all, though, really good job with the programming, and your usual awesome level of comedy in the video.

When CodeBullet accidentally codes nuclear fission simulation into a fruit matching game…

3:07 he clicked so fast that the first fruit spawned itself twice in the same space, fusing on the spot to make a strawberry

Waiting for the day that Code Bullet reveals he’s actually not coding anything and is just insanely good at video games

Also idk if anyone said this yet, but fun fact, in the actual Suika game, when two watermelons touch, they disappear. It's kind of weird but it will probably allow for your AI to get an infinite score, which would be cool to watch.

i absolutely love the editing style, i don’t remember the last time i was this invested in a video and the jokes are perfectly cut and i am in disbelief. I am sure the coding isn’t that easy but the editing is absolutely amazing and idk how you do this

no way code bullet accidentally created a perfect representation of a nuclear detonation using fruits and berries

5:40 That is surprising close to how a nuclear weapon works.

6:04 “if going to explode dont” 💀

dude i used to watch you as a little kid and i cant believe i found you again im so happy i love your videos so much the fact ur still using the same sprites of ur character i just love it so much thank you so much for a slice of my childhood

9:54 you just achieved the power that everyone wants

Surprisingly, nobody has mentioned the most important difference between this and the real game, which is that in the real game you can see which fruit is next in your queue. This is the sole factor that makes the game significantly skill based.

One thing to consider is that a person playing the game can wait for the fruit to settle, you don't have to drop the next fruit right away. This AI seems to only be able to drop the fruit at a set interval.

7:42 for the best edit, i want that screen as a music eq visualization now. CB you are getting so dang good at this! You edits have always felt fun to watch, ll yhe way back, just genuinely funny timing and enjoyable transitions that felt abrupt but meaningful. Now its one long deep fried brain rollercoaster of the gosh darn best gaming related content i enjoy on RU-vid lol.

I just love the consistency of these videos and the quality! Thank you so much for your hard work!

Can you do more in depth code breakdowns in your 2nd channel? Like not too much into the nitty gritty, but explain stuff like your general coding process, what things worked and didn’t work, and what how you specifically implemented the genetic algorithm for this game?

Seeing Northernlions face anywhere in this video was the absolute last thing I expected lmfao

Thank you so much for uploading I cant comprehend how hard you work on these videos i love you (glazzing)

Love the energy! First video I watch of you and I'll most certainly be coming back for more.

One of the things that was drilled into my head in school was to regularly save my work. Your crash and losing everything is exactly why.

as someone who has watched streamers play this game for countless hours - one of the biggest challenges in this game is its popping mechanism. when fruits combine they kind of jump around, push and move other fruits and sometimes a fruit can pop out of the container making you Insta lose. Can you PLEASE make a part two !!! would love to see the AI struggle with the rng.

8:30 what the fuck💀

I’m under 2 minutes into this video and you’re already one of my new favorite RU-vidrs. Time to binge watch a bunch of your content 😂

Only thing missing is the combination "explosion" that happens in the original game. Makes the game way harder imo. (Apart from the 2 watermelons canceling each other out that others already mentioned.)

4:55 Bro created nuclear fission but with fruits

incredible feat, smooth and onspot music/sound, hilarious script as always, keep it going cb. one

A bit of personal sharing here. Wanted to say thank you, I have busy life and always pushed away my interest for learning how to code, yet your ridiculous videos actually motivated me to start learning. (I used your brilliant affiliate link just cause you deserve it). Who knew... an AI entity convince me to actually learn its language (I still question if you're actually human... mostly the TV head makes me skeptic). All jokes aside, great content and thanks for the strange inspiration to try this out. Any tips will be appreciated. So far my plan is to do every computer science and data lesson. (I'm pretty comfortable with math and physics... I guess an engineering degree is not entirely useless)

Each video is like a different genre of chaos, and I am _here for it_

5:15 i just realized that chain reaction is perfectly match with Oppenheimer's Nuclear Apocalypse Math

Been subscribed since 2017 love to see that you’ve come so far love you code bullet

This is great. I freaking love this channel.

Its honestly amazing to see how simple some of the games that get really popular are (suika game, vampire survivors, wordle). It really goes to show how important creativity and an idea is in game development, along with proper execution of said idea.

4:13 #justiceforHenry

Fantastic demonstration of how choice of loss/fitness, and how that’s informed by domain knowledge, is so crucial to getting machine learning to do literally anything

Wow, great video! We need part 2! I would like to know if AI can react to knowing the next predicted fruit, I would say yes, so the "hardest" part would be to implement that on your mockup game. And of course the physics and 2 Suika merging, like other viewers had said.

Oh my god the NorthernLion jumpscare at 1:00 caught me so off guard! I've been watching the egg for nearly a decade at this point, so to see another of my favorite RU-vidrs also watching his content makes me so happy

There are a couple of improvements to make the game more like the original: When 2 fruits evolve, they create a little explosion, moving the fruits that are touching them in the moment of the evolution, this kind of explosion increases strength depending on the size of the fruit (in order to understand my words better you could watch frame by frame a fruit evolution from the original game) 2 watermelons evolve to air, so the AI could get infinite score

3:41 Oh woah that actually does look really fun! I hope you release a version of it in the future 😄

2:06 lol, we've all been there dude. ctrl-alt-delete, praying you saved recently - good times.

I love the journey from “don’t worry this will be cool” to “OH GOD WHY IS EVERYTHING ON FRUITY-TASTING FIRE” to “Oh, hey! Success! On to the next part to program” that takes place in Bullet’s videos. 😆

Honestly the best programming vid I've seen in years. I really felt the failure to save down deep.

Code bullet might be one of the funniest youtuber i know, thank you for the incredible editing 😂😂

Your humor deserved a sub 😂 loved it haha

most of the game clones are missing an important mechanic... the explosion which occured when 2 fruits joined. watching people rage when cherries got catapulted due to unexpected chain is the best part IMO.

One thing not mentioned, was the weight of the fruit. I dont know how you calculated it, but it always seemed like all the fruit weighed the same and their density changed, making cherries oppressive as hell and shifting the whole board without much warning

It was very cool to see you explain that bug. Thank you.

5:25 this behavior is actually fascinatingly similar to how real atomic bombs work

Fun fact: Suika means watermelon, and the kanji used is literally water + melon.

Jesus christ, when did your production value go through the roof! God damn. Nice work!

solid-ass video this time around, nice job dude

4:48 - Code Bullet created Suika game, but... Oppenheimer edition.

In the real Suika game, sometimes merging fruits causes the fruits above them to launch into space making you lose. There were times when it looked like that could have happened when your AI was playing.

I’d love to see a longer version of your process developing the game

I'm amazed by how quick you made this video with a nice quality, totally surpassed your past

Instead of doing the chain thing (which sounds expensive to calculate), you could've just calculated an inverted 'fruit score' based on their distance from the bottom and their size, so a fruit of size 1 at position 0 == decent, a fruit of size 15 at position 15 == 225, which is bad. This would mean that the larger a fruit gets, the more it's punished by being at the top. That plus a 'average weight of fruit times total number of fruit' on screen (i.e. 2x 1 + 1x 16 = 6, but 1x 2 + 1x 16 = 9) would give you a good indicator of efficiency at very low calculation cost

CB: "It's like children you gotta kill a couple to make an omelette" 8:35

I find there to be something deeply funny that Suika Game got a steam port two days before the video came out and Im only now learning about it F that you had to remake it for this but was an interesting part of the vid seeing it be made

Yay this years code bullet video

To be honest that’s not far of nuclear fission ☢️ 5:45

I think something that makes a big difference on how the game plays that isn't included in this version is that when two fruits join, they explode, shoving the fruit around them. if there's a cherry on top of a peach or pineapple, there's a decent chance it gets shot outside of the play zone

I was waiting so long for this.

First time watcher, and gotta say love the energy ❤

6:53 was the PTSD necessary?

8:58 Generation 93 Sample 5 had a melon I believe, and he deserves more respect Mr “Bullet”, if that’s even your real name

Great video, had fun watching it!

First video from this dude ive seen. How did i not find this dude sooner hes awesome 😂

I actually cant be bothered to care how coding and game design works for the most part. Your humor is 90% of why i watch. The interesting struggles you go through and the game choice is the other 10%.

1:42 before something clipped out of bounds, I was getting concerned I wasn't watching code bullet.

Kay, legit had never seen a video of yours but now I'm obsessed with Suika but bounce. Pleaseee release the code!!!

Oh holy- I have never seen this channel before but I’m laughing and NMSMSMSM ughhh this kind of content is right up my alley :D

Frames like this, make me question how much ram you have (7:00)

5:55 Please give in depth answers to some bugs in future videos! Love seeing the little things that can go wrong and I can avoid in my own code. This explanation of the exploding glitch was awesome!

I would love to see a Sudoku AI. I’m no programmer, but it seems like it would be slightly challenging and Bullet could make it hilarious.

Why did I just discover this channel I love you

Oppenheimer would be proud. 5:23

5:10 Fruit Oppenheimer

I love watching you go insane

Damn this is the most entertaining coding video I’ve seen in a long time. Love it.

now just imagine if code bullet found out that you can run genetic algorithms without rendering the game and calculating physics frame by frame. Edit: For clarification, what I meant was that you can progress the AI via an unrendered simulation of the game with approximated physics, saving significant computation, and then you can render one version from each generation to show progression in a video.

I think the fruit bounce a bit more when they combine in the actual game. That's actually a hard and unpredictable part of Suika game.

Yeeeeee Code Bullet is back!!!!! Finally the handsomeman let him of the leash ! Btw Your Animator is a King!

The THX sound system meme (for some reason) got me rolling. Great video!

As soon as I saw this game, I knew you would make an AI to beat it lol Hyped to watch :)

2:22 remember: unused ram is wasted ram

Not into coding or anything but your videos are pretty informative and intriguing nonetheless. Thank you for the content you produce.

Breh u is too funny maan thanks for the video😂❤

I’m pretty sure Code Bullet just explained nuclear fission

This video was awesome! I'm not even really a fan of the Suika game but the editing in the beginning had me laughing out loud multiple times. I really liked your strategy for the algorithm of "Fruit Chains" because it does seem to be a good strategy to look for, rather than just brute forcing with the score as the determining factor. Overall great video! Very interesting, funny, and well put together.

love this channel

Great video mate!!

Can we just talk about how CB just described nuclear fission and a nuclear meltdown in this video @5:00
