And you probably won't until you start testing the thing you needed it for 3 phases down the line, so it'll take you extra long to find where it is. Also with the collective luck of all people involved, it's a single misplaced negative
Collision in general is stupid hard to do from scratch. Unity? Kinda hard. Unreal? Less hard, I guess. Game maker? Still kinda hard. Even in my own custom made game engine, its way easier but…. still kinda hard :| Or maybe Im just really bad as a programmer, who knows
There is nothing more terrifying than when code works the first time immediately. How can we know it really works if we don't spend hours fixing the bugs?
It happened once to me, I tested it like 10 times and it seemed to just work, it was for an assignment and honestly I just took that gift from the gods and it only had to work once more for the tutor to grade me and it did :). Honestly I don't know if I was just lucky it work 11 times in a row or it really actually just really worked first try.
I love how the second AI effectively decides to become a challenge runner by removing the part of it's brain responsible for jumping, just because it could-

@pw7225 correct, but the name of my university department is "Artificial Intelligence Engineering". i live with people who call themselves prompt engineers, soo who gives a fuck XD
Repent and believe in Jesus Christ i am just thinkin, that there is a religious programmer out there who uses all the resources he can to influence people on youtube comments without making a youtube video. He releases all these bots here expecting people to let go of their beliefs and follow Christianity. If he could give all this effort into philosophy and science, he would become an atheist
The swearing is especially accurate. I curse every single entity imaginable, mostly my computer and myself and anyone who dares to message me at the time.
I absolutely love how accurate you show the process of coding, just fail after fail until somehow it works and you’re not really completely sure why but hey it works so it’s all good
Well have seen same yt creator's that show failures more regularly and everyone is doing good but CB is the master of this discipline and his very loyal sub show us that
There’s a Russian anecdote which, in translated form, goes something like this: « Dad, why does the sun go from east to west every day? » « East to west? » « Yes » « Every day? » « Yes » « I don’t know son, but better leave it alone » It’s a stupid anecdote, but one of my favourites when it comes to programming
There's test-driven development, where you write a test for everything that should and should not happen, e.g. jumpman jumps at least once per game, and over time more tests pass. It's a lot of work, but the benefit is it will catch regressions; as we see here when Jumpman sometimes flies into the air after Code Bullet thought he'd fixed gravity issues.
@skierpage I'd love to be able to apply TDD to game development, but the number of states and the non-deterministic means of reaching those states most games have means that you end up with very, very low coverage of the code base and/or end up pointlessly testing third party code. I've seen fat too many "tutorials" where the speaker just tests engine code
When you mentioned the jumping, or absolute lack of them doing it in NEAT, I instantly had a vision of you adding points for jumping over barrels and the AI dudes going balls first sailing back and forth over the barrels instead of going to the end. Just racking up massive points for themselves over and over again.
PPO is basically strapping the AI to an N-dimensional sled and punting it down the N-dimensional hill. You need to choose how big a sled to use, how much momentum to conserve, and even how the hill looks like. And in the end when you think you reached the bottom and looking for an N-dimensional cable car to take you up for more you find out that you are in a shallow N-dimensional depression somewhere half way down the N dimensional hill. Where N is the amount of weights you are using.
@maartenbeute6742 yes but PPO is a specific algorithm describing how to leverage a neural network (actually two neural networks), so just describing how to fit the parameters of any model doesn't tell people very much. The method above could also be given as a description for how to do linear regression, for example. Or image classification. Or basically any machine learning task.
@maartenbeute6742 If you want to see how an explanation of the actual algorithm would look, this link should take you to my other comment where I explained it: ruclips.net/video/ovIykchkW5I/video.html&lc=UgxFRqioM8iaM4rJvs54AaABAg
When you jump, you apply a strong upward force. This is stronger than the constant downward force of gravity, so the player moves up. Once the jump force runs out, gravity is the only force left, pulling the player down. Gravity is always on, you just dont decrease the player's y-position if its equal to the ground level. so like in code example you would do smth like, decrease player Y unless the ground Y is lower player.y = Math.min(player.y + gravity_force, ground.y)
But the only reason you don't get pushed THROUGH the surface is because of normal reaction force, which counteracts gravity. So the net force acting on you is 0
Despite your hatred of explaining, you did an amazing job defining and explaining each AI algorithm…while not simultaneously putting me asleep in the process. Great video and always very entertaining! 🔥
@missionpupaI mean the overwatch 2 AIs will walk through walls sometimes because they have found pixel wide gaps and can spam input movement commands every tick so they can just kinda clip through the walls then shoot you from under the map it’s not really a failure of parameters as much as a failure to block exploits
You mentioned the RNG involved with the barrels, but fun fact about the OG donkey kong. Whether a barrel goes down a ladder or not is based on where the player is and what direction they are facing so you can actually control when the barrels go down ladders, which would have been cool to see how the AI learns to manipulate it Also a huge pain in the ass to code so who knows if it would have been worth it
Also would have been interesting to see how the AI would coupe with a four way joystick. You can't turn and travel on ladders. But that's beyond the scope CB is at ... For now.
Code Bullet really is the best inspiration. He doesn't hide or gloss over his mistakes and in so doing shows that coding really is a perpetual state of learning through trial and error. And then promptly forgetting everything while we binge our next dopamine fix instead of working. Seriously though, I really appreciate that you include the struggle of being human in your videos. It makes them so much more relatable.
Not to brag or something, but.... I'm not sure that it is that hard unless you learned something. Floor not working is sort of close, but not for THAT long
Neat detail I noticed that wasn't brought up. At 2:46 you can see the player square falls all the platform a bit early, when it's only halfway off, which causes it to clip into the floor a bit. This is because the "laser" vector that detects if the floor is there is positioned in the middle of the square, and therefore doesn't detect the ground when the square is only halfway off. This is silently fixed at 2:58, where the square now only falls when it's fully off the platform. As you can see, the lasers are on either side of the square, making sure both have to be off the platform before it falls.
I love how you somehow have the most inconsistent upload schedule, it takes you hundreds of attempts just to get code right per episode, and yet somehow you also have 2.7 million subscribers. Congratz!
I couldn't believe a coding channel with nearly 3M subscribers has to deal with the exact same shit as I did when I was really into Game Maker in my free teenager time
The jokes and screwing around in the first 4 minutes got you a new sub. The "breath of fresh air" bonus is how you're not afraid to swear and genuinely enjoy what you do even when your code doesn't work.
@WingMaster562 same tbh, I was just sitting here thinking "Wouldn't just a simple AABB collision algorithm be better?" but hey, he makes games on youtube for a living so he probably knows whats best
As much as CodeBullet struggled, it was still impressive once he started driving over those ramps with relative ease near the end. Couldn't ask for better entertainment. The part where he made an AI was cool too.
I actually really like how you explained everything! Most of the time when a youtuber makes “AI plays X” or “AI learns to Y” They don’t explain in more detail how they did it, or they skip over a lot of the crucial information when it comes to it. Thanks for going the extra mile and actually going into things, even if only a little bit.
"skip over a lot of crucial information" that precisely describes his explanation. No critique towards him, explaining that shit takes ages and I understand why he doesn't do it (it would also be boring af), but he doesn't explain it well.
@EvykhaitsSchmurf-tg7gehe doesn’t explain it well or in depth to every kind of code… he explains to us neruron activation monkeys in a way we will understand and at a level deep enough to explain some nugget of inform without boring us.
I always love seeing timelapeses of bug fixing in videos where someone shows themselves coding - Being a java developer myself, I can truly appreciate that :P
24:15 There's a sentiment I can get behind! Instead of fixing the bugs, teach the AI to avoid them at all costs! Lol, this was an interesting video, thanks for comparing the three, I liked how you mentioned the strengths and weaknesses of them and how it's more like a "pick the best tool for the job" than it is "this one is the best".
At 9:39, CB states "2 extra nipples" while adding 2 nipples to a nipple-less entity, presumably a human. However, we are aware that all humans have 2 nipples by default. Therefore, we can conclude that CB canonically has 0 nipples.
After talking to people that work with AI, one of the things they mostly agree on is that not even they have any idea what is going on in the back end.
@Hypernova7777Look up how neural networks function, it’s not actually very complicated on paper. The issue is that with enough nodes, it becomes impossible for humans to possibly follow exactly what’s happening in the “brain” of the AI.
NEAT is pretty neat... (*groan*) One problem with it is that it often throws away good solutions because the mutation can often be quite aggressive and throw out long-term positive traits for short-term gains. That said: This is literally how real-world genetic evolution works too. So for this algorithm, it pays #1 to have bigger population sizes, #2 to be careful about your mutation rate, and #3 to give it enough time to run. In all experiments I did with it, it often reaches a plateau where not much happens for many generations, but after a long time, it suddenly starts improving again. I'm pretty sure it has to do with the "species" system it uses: Often, one species is so good at what it does, that even "geniuses" in other species don't have enough impact to lift their otherwise mediocre species above the king of the hill species. This can lead to situations, where species with the potential to become the new best species die out before ever getting the chance to reach their full potential. So, like I said: It works just like natural genetic evolution... A species doesn't automatically survive just because it is fitter. There also have to be the right set of random circumstances to allow them to succeed. P.S.: One interesting experiment you can do with NEAT is to have to mutation rate ALSO me a trait that can be mutated. That leads to some low-mutation species that keep SLOWLY improving their positive traits and several high-mutation species that keep trying out random stuff. This stops a typical problem in machine learning: The algorithm settling in a "just-good-enough" plateau instead of keeping to improve in the hopes of finding an "even better" plateau further down the line.
Code Bullet always delivers!!! Also for me, I loved the explanations and the glimpse behind the scenes. I know if the video gets too technical viewer retention kind of takes a hit, but this time, I thought there was a healthy amount of "nerd-talk". Ty!
21:30 "As soon as some letter start wearing little hats..." The funniest part about that is that it is called a hat. The A is A hat. At least in stats and I assume tin this context as well.
Your video editing gets better and better with time. I believe this one is the best so far for various reasons. Just want to say I recognize and appreciate your efforts. Well done.
@ki0w0-lordofwatersheep The animations were great, but it's other little things that have improved as well. The Dialogue, the tempo,, The video overall feels more cohesive while retaining all of the wonderful chaotic energy of previous vids.
I like to imagine the time between episodes is actually spent making more poses for codebullet's vtuber sona, and he hammers this code out like a legend over the course of an afternoon.
(23:00) You should preferably also set the distance to the nearest ladder upwards and nearest ladder downwards. Since you can add a lot of inputs, the nearest ladder upward can also have the inputs for the next barrel to that ladder that might fall down it.
1:50 "I'm scared" Man I relate so much, that's so true. The worst in programming is not "It doesn't work and I don't know why", it's "It WORKS and I don't know why!"
Awesome video! Your combination of code and tons of humor cracks me up. As for your AI? I will only say the following: Still less cheating involved than Billy Mitchell's runs. (And still a better love story than Twilight.)
Next time you want ChatGPT to explain something, ask it to explain it in the style of Code Bullet. I really want to see you react to it trying to imitate you. I checked, and it absolutely knows about you.
ChatGPT doesn't really know what it's talking about with games and stuff in general. It told me that Ghost type is super effective against Fairy type in Pokemon, which is just entirely wrong
I think that you need to add a zone that will eventually rise from the bottom, and you need to divide it into levels, and if the AI touches the highest level, then one point will be taken from it, if it touches the level below two points will be taken away from it, etc. This provokes the AI to climb faster rather than stay still.
I made a really crude, crappy AI that learned Super Mario Bros (the first level...) and it helped to reward them for moving, penalize for stopping too long, and immediately kill if they don't move within the first second.
I loved that you went more in depth this time! I can imagine a lot of us here watch and enjoy your videos because we're programmers ourselves, so getting more details is always interesting (in my opinion). Loved the video!
i love even coding experts go through a ton of challenges when it comes to coding. also the thing of just “moving a red square across the screen”. like bro, that’s a big step when it comes to coding😂. like all u have to do now is get a character and then change it from the square to ur character of choice and then now u have a person that moves instead of a square
As a wise man once said: “if your code works perfectly first try, it didn’t, you just haven’t noticed what’s broken yet”
I have never heard so much wisdom in a single sentence.
Truly inspiring
And you probably won't until you start testing the thing you needed it for 3 phases down the line, so it'll take you extra long to find where it is. Also with the collective luck of all people involved, it's a single misplaced negative
As a wise man once said: we don't talk about the last video
I once coded for 2 weeks without access to testing it, and had it working perfectly in 5 minutes. In my entire career this was my proudest moment.
That whole "Ground? No." bit was painfully accurate to the game dev experience.
this 100%
No fucking way 345+ game devs are watching this...
Very relatable to my experience with "gamemaker5&6" in the early 00s.
And that program should've made that whole process way easier.... 🤣
Collision in general is stupid hard to do from scratch. Unity? Kinda hard. Unreal? Less hard, I guess. Game maker? Still kinda hard. Even in my own custom made game engine, its way easier but…. still kinda hard :|
Or maybe Im just really bad as a programmer, who knows
@@syntex3664 Because that's the thing with programming, if you somehow made something work the first time, you should probably visit an exorcist.
There is nothing more terrifying than when code works the first time immediately. How can we know it really works if we don't spend hours fixing the bugs?
"The code works flawlessly first try" is what happens to programmers when the world turns upside down.
Spoken like a true unit-test averse programmer!
Learn test-driven development. Then you will be surprised if it doesn't work immediately.
@jimmyhirr5773 believe it or not. Tests are also written with code. Which can also have bugs!
It happened once to me, I tested it like 10 times and it seemed to just work, it was for an assignment and honestly I just took that gift from the gods and it only had to work once more for the tutor to grade me and it did :). Honestly I don't know if I was just lucky it work 11 times in a row or it really actually just really worked first try.
Now make a Donkey Kong AI that learns the best barrel throwing strategies and pit them against each other for eternity
But that was the first version of Donkey Kong he made, it threw infinity barrels.
@dreemurrdelm7865 just give the ai a reload time so it can't spam
give the barrels ai so they know when to climb and not climb arrows to fuck up with the mario/player ai
ladders not arrows*
Go full GAN. 2 AIs, DK and Jumpman trapped in never ending combat with eachother.

Well, he is training a neural net...
Its called learning over time
now he just needs to code in some better jokes
This is hilarious 😂
Every code bullet video is an event that should be treated with utmost respect.
Which is why none existed in 2021.

as an Artificial Intelligence Engineer, I can confirm we tickle the balls of the reinforcement learning agents as a reward function. Its one of the best ones out there.
No ML engineer would call himself AI engineer.

It’s a stupid anecdote, but one of my favourites when it comes to programming

@skierpage I'd love to be able to apply TDD to game development, but the number of states and the non-deterministic means of reaching those states most games have means that you end up with very, very low coverage of the code base and/or end up pointlessly testing third party code. I've seen fat too many "tutorials" where the speaker just tests engine code
and then it suddenly doesnt

PPO is basically strapping the AI to an N-dimensional sled and punting it down the N-dimensional hill. You need to choose how big a sled to use, how much momentum to conserve, and even how the hill looks like. And in the end when you think you reached the bottom and looking for an N-dimensional cable car to take you up for more you find out that you are in a shallow N-dimensional depression somewhere half way down the N dimensional hill. Where N is the amount of weights you are using.
That's just gradient descent mostly, not really specific to PPO
I love 150 dimensional sleds on 150 dimensional hills, but it seems like a pretty good anecdote
@MaxLennon but the gradient descent is used to find the most optimal values for a neutral netwerk
@maartenbeute6742 yes but PPO is a specific algorithm describing how to leverage a neural network (actually two neural networks), so just describing how to fit the parameters of any model doesn't tell people very much.

Life: gravity pushes you against the surface below you
Code: gravity shuts off if you're touching the ground
I mean the correct way to make gravity function is to keep it running all time, it just cant decrease your Y position further than the ground
@sshw_t
saw a RUclips short about this once, wouldn’t that mean that the downwards acceleration would build up or something?
When you jump, you apply a strong upward force. This is stronger than the constant downward force of gravity, so the player moves up. Once the jump force runs out, gravity is the only force left, pulling the player down. Gravity is always on, you just dont decrease the player's y-position if its equal to the ground level.
so like in code example you would do smth like, decrease player Y unless the ground Y is lower
player.y = Math.min(player.y + gravity_force, ground.y)
But the only reason you don't get pushed THROUGH the surface is because of normal reaction force, which counteracts gravity. So the net force acting on you is 0
DONKEY KONG?
You surprise us with the most varied yet entertaining video games to let an AI learn.
Thank you
I didn't expect him to make a donkey kong AI tbh.
Less than a minute in and he's already killing clones, and he's also learned and used a silenced gun too, this is definitely gonna be good

I agree, I leanred more from code bullet than high school
Code bullet explains his coding better than my lecturers does and that’s saying something
he takes your understanding of it seriously.
it's the dick jokes, they help

Well he is paid to so makes sense. Oh wait…
one of the best things about these is when your AI finds out a trick to your programming and starts exploiting you. funny as hell
Is it exploiting or failure to limit parameters? I mean the Ai just does what you asked it to do, it has no concept of cheating or exploitation.

CodeBullet still having to watch tutorials on the most simple thing start to become more relatable the further I get in my software studies
I was half expecting your "AI learns to run" videos to be the only two videos in one year.
Good for you to have another one. And us.
I love the extremely 2020’s approach of using raycasting for floor detection. The original Donkey Kong programmer would have lost their mind. 😂
I too lost my mind for a bit
@WingMaster562 same tbh, I was just sitting here thinking "Wouldn't just a simple AABB collision algorithm be better?" but hey, he makes games on youtube for a living so he probably knows whats best
@MythicTF2 trust him, he doesn't
@treeck3724 such an unwieldy way to code, it's fun to watch though
Its resource heavy and unnecessary. If OG DK used ray casting EVERY FRAME TO SEE THE GROUND it would crash the game.
11:55 I love watching the singular mario suddenly replicating like a bacteria
The fact that he has the Honest Trailers epic voice guy read the AI explanation made it so much better.
Was that a cameo or some text to speech generator we should all be aware of? 😄

There's a certain irony in Code Bullet disliking an AI's explanation of AI techniques and preferring his own human explanation

As much as CodeBullet struggled, it was still impressive once he started driving over those ramps with relative ease near the end. Couldn't ask for better entertainment. The part where he made an AI was cool too.
Honestly, the whole part of debugging the gameplay and code was the most accurate representation of game development.
I actually really like how you explained everything!

They don’t explain in more detail how they did it, or they skip over a lot of the crucial information when it comes to it.

we love code bullet
Code Bullet actually shoots the relevant knowledge into your brain. Hence the name.
"So as to how this thing works, -- your guess is as good as mine, I have no f*cking idea but at least it works"
"skip over a lot of crucial information" that precisely describes his explanation. No critique towards him, explaining that shit takes ages and I understand why he doesn't do it (it would also be boring af), but he doesn't explain it well.
@EvykhaitsSchmurf-tg7gehe doesn’t explain it well or in depth to every kind of code… he explains to us neruron activation monkeys in a way we will understand and at a level deep enough to explain some nugget of inform without boring us.
26:20, it always takes the shortest path, but the safest path would be for them to climb the far right ladder from 5th girder to 6th.
Instead of fixing the ladder glitch in PPO algo Code Bullet punishing the AI for falling off is such a good parent move
I always love seeing timelapeses of bug fixing in videos where someone shows themselves coding - Being a java developer myself, I can truly appreciate that :P
This is honestly one of the best, if not the best Code Bullet video there is. It was an absolute blast to watch
My favourite is the Tetris video
Yeah so funny ong
21:52 is that... The Skyrim U.i. font?
The chaotic energy in these videos just keeps growing and I'm absolutely on board.
I love watching a successful programming channel that doesn't understand letters with hats on them either just like me! So quirky and relatable
24:15 There's a sentiment I can get behind! Instead of fixing the bugs, teach the AI to avoid them at all costs! Lol, this was an interesting video, thanks for comparing the three, I liked how you mentioned the strengths and weaknesses of them and how it's more like a "pick the best tool for the job" than it is "this one is the best".

Instead of paying money to fix the hole in the floor teach the baby not to fall in it
12:28 i already have this video popped out and in the corner of my game while i grind 😭
At 9:39, CB states "2 extra nipples" while adding 2 nipples to a nipple-less entity, presumably a human. However, we are aware that all humans have 2 nipples by default. Therefore, we can conclude that CB canonically has 0 nipples.
After talking to people that work with AI, one of the things they mostly agree on is that not even they have any idea what is going on in the back end.
What IS going on in the back end?
That question is harder to answer than physics probably
@Hypernova7777Look up how neural networks function, it’s not actually very complicated on paper. The issue is that with enough nodes, it becomes impossible for humans to possibly follow exactly what’s happening in the “brain” of the AI.
@IAmUnderscore That's what I meant...
I know the base stuff about nodes.
@Hypernova7777 Ooookkayyy….
@IAmUnderscore I took a class on this
As a person who has no idea how to code, I can say that your videos are very entertaining
18:25 I can’t unsee that one google ad when I hear this music
13:33 The AI finding a glitch and taking advantage of it is freaking awesome 🤣
Even spiffing brit isn't safe from ai
@Alucard-gt1zf The Genetic Algorithm is a perfectly balanced game with no exploits
NEAT is pretty neat... (*groan*) One problem with it is that it often throws away good solutions because the mutation can often be quite aggressive and throw out long-term positive traits for short-term gains. That said: This is literally how real-world genetic evolution works too. So for this algorithm, it pays #1 to have bigger population sizes, #2 to be careful about your mutation rate, and #3 to give it enough time to run. In all experiments I did with it, it often reaches a plateau where not much happens for many generations, but after a long time, it suddenly starts improving again. I'm pretty sure it has to do with the "species" system it uses: Often, one species is so good at what it does, that even "geniuses" in other species don't have enough impact to lift their otherwise mediocre species above the king of the hill species. This can lead to situations, where species with the potential to become the new best species die out before ever getting the chance to reach their full potential. So, like I said: It works just like natural genetic evolution... A species doesn't automatically survive just because it is fitter. There also have to be the right set of random circumstances to allow them to succeed.
P.S.: One interesting experiment you can do with NEAT is to have to mutation rate ALSO me a trait that can be mutated. That leads to some low-mutation species that keep SLOWLY improving their positive traits and several high-mutation species that keep trying out random stuff. This stops a typical problem in machine learning: The algorithm settling in a "just-good-enough" plateau instead of keeping to improve in the hopes of finding an "even better" plateau further down the line.

It's nice to know that even simulated evolution suffers carcination.

@CalvinArt nft pfp lookin mf
you can implement speciation to fix the "aggressive" problem
12:45 thank god for the car video, I lost interest 0.0000004 seconds into the timelapse and I really needed it to help with focus
24:08 ah yes, giving someone a punishment for allowing a problem to occur instead of actually fixing said problem, _where have i seen that before_
I love the chaos of the process. It really gives you a sense of how many times it truly takes programmers to get stuff done 😂
This man has the most elite upload schedule 😂
it took me the same time it took him to upload 15 of his videos (provided he doesn't upload for two months... which is guaranteed) to get a cs deegree
@thomask2133 provided you actually get the degree 😏
18:22 where's our car??????????? my gen z brain cant function without gtav gameplay covering half of the screen D:
block going straight up at @4:20 lmaooooo
I like how nobody really forgets about the Enigma machine even after 5 years
Evan is such a nice guy, always keeps his promises, especially Enigma Machine Part 2
@nubbyboi6523 Yeah, he'll probably make it in the next...millennia.
@GooberInternet Better than his normal upload schedule 💀
@nubbyboi6523Wait until it’s 2068
TemmiePlays any chance you would do it for us? 👀
Code Bullet always delivers!!!
Also for me, I loved the explanations and the glimpse behind the scenes.
I know if the video gets too technical viewer retention kind of takes a hit, but this time, I thought there was a healthy amount of "nerd-talk". Ty!
I too feel that excitement when testing basic movements. People got no idea how tedious it is to implement those perfectly…
The Jon Bailey cameo is the crossover I didn't know I needed.

21:30 "As soon as some letter start wearing little hats..."
The funniest part about that is that it is called a hat. The A is A hat. At least in stats and I assume tin this context as well.
12:24 *NOOOOOOO, KEEP THIS IN THE TICK-TOCK QUARANTINE ZONE*
I feel like I'm being spoiled with so much Code Bullet content in such a small span of time.
This is halfway between a bad trip and a good day. Like a train wreck I can’t look away until it’s all straightened out.
13:38 Code Bullet is so good at coding, the AI felt necessary to learn speedrunning!
Honestly... I love your editing style and your content. I continue to admire your effort and sacrifice!
I like the balance between random entertainment and coding/AI a lot more in this video than the last. Always love the uploads!
5:06 "but because im a good boy and nintendo has lawyers" yeah i tought about that
it's hard to describe the fear of something working the first time when you know it SHOULDN'T HAVE WORKED THE FIRST TIME
I now see why it takes you so long to upload. Creating a bug every single time you add a new feature is a genuine gift. Never change
6:29 when you set the difficulty on Dark Souls
Yeah lol
19:10
"Sigh"
*checks comments*
Your video editing gets better and better with time. I believe this one is the best so far for various reasons. Just want to say I recognize and appreciate your efforts. Well done.
The ✨animations✨
@ki0w0-lordofwatersheep The animations were great, but it's other little things that have improved as well. The Dialogue, the tempo,, The video overall feels more cohesive while retaining all of the wonderful chaotic energy of previous vids.
I like to imagine the time between episodes is actually spent making more poses for codebullet's vtuber sona, and he hammers this code out like a legend over the course of an afternoon.
(23:00) You should preferably also set the distance to the nearest ladder upwards and nearest ladder downwards. Since you can add a lot of inputs, the nearest ladder upward can also have the inputs for the next barrel to that ladder that might fall down it.
22:05 I was rolling in my bed after this bit 💀💀💀😭😭😭🙏
1:50 "I'm scared"
Man I relate so much, that's so true.
The worst in programming is not "It doesn't work and I don't know why", it's "It WORKS and I don't know why!"
Awesome video! Your combination of code and tons of humor cracks me up.
As for your AI?
I will only say the following:
Still less cheating involved than Billy Mitchell's runs.
(And still a better love story than Twilight.)
Careful, you might get a lawsuit
@CaitlinTheTransOtter Would love to help him towards his next loss ;)
Completely forgot you were planning to make an ai. It was so intriguing to watch you just rebuild the game. 2 awesome subjects in one video
I have never seen someone make it all the way down the ramp like that in GTA. I was HOOKED on that omg.
Next time you want ChatGPT to explain something, ask it to explain it in the style of Code Bullet. I really want to see you react to it trying to imitate you. I checked, and it absolutely knows about you.
That's genius, I need to try it now
ChatGPT doesn't really know what it's talking about with games and stuff in general. It told me that Ghost type is super effective against Fairy type in Pokemon, which is just entirely wrong
Gotta love to watch another 30 minutes of talking TV with a bullet on it! Jokes aside, great content!
I think that you need to add a zone that will eventually rise from the bottom, and you need to divide it into levels, and if the AI touches the highest level, then one point will be taken from it, if it touches the level below two points will be taken away from it, etc. This provokes the AI to climb faster rather than stay still.
I made a really crude, crappy AI that learned Super Mario Bros (the first level...) and it helped to reward them for moving, penalize for stopping too long, and immediately kill if they don't move within the first second.
I think the ai liked to hide behind donkey kong because it counted as them "missing barrels" and gave extra points
16:52 that broke me
3 AIs competing was really interesting. It laid out a lot of pros and cons of each while showing actual results. Nice 👍
I loved that you went more in depth this time! I can imagine a lot of us here watch and enjoy your videos because we're programmers ourselves, so getting more details is always interesting (in my opinion). Loved the video!
8:33 is that Honest Game Trailers lol
i love even coding experts go through a ton of challenges when it comes to coding. also the thing of just “moving a red square across the screen”. like bro, that’s a big step when it comes to coding😂. like all u have to do now is get a character and then change it from the square to ur character of choice and then now u have a person that moves instead of a square
"Man, this insomnia sucks. I should atleast try to get to sleep though."
*Code Bullet uploads
"What's 30 more minutes?"
1:56 that panic when your code works without needing to debug🤣🤣🤣
I like when car syncs in timelapse
