[@crthejediknightninja]

3:08 So what we are seeing here is actually what allows Mario to clip through doors with BLJs in SM64, if the square moved fast enough, it would blow right through the line because it's checking for collision frame by frame, if there isn't a frame where collision happens, then collision CAN'T happen. Again at 9:41, character reaches basically escape velocity and they move fast enough to just teleport on the other side of the collision wall.

[@arpitez]

Thanks for the explanation

[@SkeletalElite]

Happens in halo infinite as well if I remember correctly, lot of speed runners use it to OOB

[@boingboingresearcherph.d.2871]

9:41 it moved so fast that the next frame was drawn out of the supposed colission line right? 3:08 the collision line was inside the character during the refresh...?

[@nadie9058]

@@boingboingresearcherph.d.2871 It did, the whole player was suddenly at the other side of the line so no collision happened. And the collision line was inside because at first he didn't code the behavior to snap back. Many games snap back based on direction so if you change direction at the exact same frame you snap back inside the collision, this is used to clip through walls on the Super Mario from the NES. On SM64 I don't know the whole thing, but i would guess it was similar, though in that game i would say it's near impossible to turn on the same frame and it calculates the collision on four steps from the previous to the new position so you would have to be a lot faster, TAS runs manage it due to weird glitches that allow them to go several thousand times normal speed.

It's actually an evolutionary algorithm, even more interesting.

[@coreyfrank506]

@@mattiabilla it's an evolutionary algorithm that narrows down the final path by brute forcing many options until a generation succeeds better than the previous. Its an ai that doesn't learn how to play the game, only which random moves get it further. The ai isn't learning things like, what jump patters it can know, where the map exits are, efficient routing, it doesn't actually learn how to play the game. It's just brute forcing every possible option until you get the combination that gets to the end of the game. Which results in the hard parts being done perfectly, and the easy parts being done like a 2 year old. The best way to say it is. This type of AI does not learn to play games. It learns to beat them through brute force.

[@mattiabilla]

​@@coreyfrank506 well, we can say that the model has a high variance, however all the AI algorithms aim to find the optimal solution by moving through the feasible region according to a strategy, in this case optimizing a fitness function with a GA. Brute forcing is just an inefficient and different strategy.

[@RayquaSr.]

"I am on top of a mountain, and I have no idea how I got here" -some ai probably

[@TheTrienco]

Ah, the memories of doing collisions and finally accepting that looking at just a "snapshot" by checking intersections is doomed to fail eventually (low fps or fast objects). While the math is a bit more complicated, you should try to find the intersection as a function of the actual movement, find the one that happens first, respond to it, adjust your velocity and recursively repeat the process until the full movement for the frame is "used up". Considering it's about the AI and not pixel perfect collision physics, that's likely overdoing it, though.

Only understood about half of that, but that sounds cool.

[@lil_zcrazyg1917]

As someone who has spent a few years learning and writing AI and Genetic Algorithms from scratch, i'd like to point out that the reason it looks like the "AI" is brute forcing its way through, is because it is. Genetic Algorithms and AI's are not the same, they may give *initially* similar results, however there is a massive difference. An AI is actually learning, a Genetic Algorithm is memorizing. You can think of it this way, an AI is built in order to generalize a data set and label it correctly, and it should in theory be able to do this for any new data you give it. A Genetic Algorithm however, is basically an optimized random function, allowing you to find the optimal labels quick for a specific data set. However it is completely unable to label new data without another round of learning and brute forcing. I'm in no way dissing this video, I actually really like it and love this channel, however, with the way the code is functioning from my perspective, it seems like its not an AI and only a Genetic Algorithm, which is why its "brute forcing" because its literally just memorizing the game and the best moves, whereas an AI would actually generalize the game, and theoretically be able to solve new custom made levels. Note that this could be using a Neural Network that trains using a genetic algorithm, however I don't believe this is the case as the amount of error in each level is very similar, the character makes multiple bad jumps and continues to do this throughout the levels in a very repetitive fashion as if it doesn't actually understand what a level is and what it needs to do.

[@sampfalcon5128]

Came to the comments for this. An AI for this game could be shown a new level and *probably* get through it a majority of its attempts. (If it was good, haha) Not to trivialize this in any way though, I get that most people won't know the difference between "AI" and genetic algorithms in a KZbin title/thumbnail. And, great coding and teaching.

[@casbyness]

Agreed. You could literally build a physical analogue to the game, then randomly throw hollow plastic counters upwards from the bottom of each section, keep the counters that land on a higher ledge whilst discarding any that fall back down, repeat the process from the position of the highest ledge reached from the previous throw each time, and you'd achieve the exact same result. The coding aspect is completely irrelevant. You could demonstrate the same outcome using pieces of paper, dice, ball bearings, etc.

[@lil_zcrazyg1917]

That's true to a point, as some levels you have to actually go lower in height to get higher at some point, however there's an easy adjustment for that. I still think this video was educational to those wanting to learn how people actually train genetic algorithms and AI's on games. So I can understand the simplification in order to get across another important aspect of this field.

[@solidzack]

Deep Learning is only a subset of machine learning and machine learning is only a subset of artificial intelligence. There are many more branches regarding AI like natural language processing for example. It's not easy to answer what's a true AI and what not. Some only consider it an AI of it learns, others believe you don't necessarily need to learn to show up intelligent behavior. Some believe an AI should generalize as much as possible, while others think an AI could also simply deal with a specific scenario in an intelligent way. It's hard to draw the line. Obviously you couldn't call a sorting algorithm an AI for example. But can you really say you need to "learn" to do a task in an intelligent way? Essentially machine learning methods are also simply algorithms. Though on that regard I don't have enough experience to form an accurate opinion.

[@joope125]

I think the part where the AI is learning is fascinating. It makes me curious about how this would have gone with that type of AI exemplified by the race car that learns to recognize the walls and avoid them. It seems like this AI is always randomly guessing 500 times. Is it possible for the iterations to get smarter jumps each generation as well as rewarding them for simply getting higher?

[@FiltyIncognito]

This AI isn't really learning anything except a single route to get as high as possible. It's actual intelligence is fixed, and dumb as a rock. It has no idea what it's doing. It's basically button mashing and the single best route of each iteration gets immortalized and copy/pasted over the other 499 routes. It's possible to make AI's that actually get smarter, but it's far more difficult. Stuff worthy of science papers. edit: I forgot the part where he made it favor going higher or getting 'tokens' when it has to go down to advance. The AI isn't dumb as rocks. More like...an amoeba? Also, I should point out that this doesn't mean CodeBullet's AI is bad. If you've got a nail, a hammer is perfectly fine tool. Renting a 50ton excavator to nail your birdhouse together is all kinds of absurd. So long as the results are acceptable who cares how jank your tools are?

@@LucasPossatti I was also wondering about that, but I actually suspect the only thing this one takes as input is the current level and current "score".

Another possible solution: Treat it as a pathfinding problem, and just draw up a map/graph/tree that records for each position and move which position it leads to.

[@lordfelidae4505]

…all the pixels? MANAGABLE?

[@XNinjaBladesXx]

Instead of all the possible positions you could generate a smaller map with random moves. Can’t remember the name but you can do say 5 random moves, then 5 another 5 from each of those and keep going as far as you want. Slap an A* search on the path options and it would probably be pretty quick.

[@tvorryn]

If you wanted to design a TAS, then you would have the costs of the edges be the number of frames it takes to walk/jump between those pixels. Then do a breadth first search (the smallest cost path gets extended next), but mark each pixel once it's reached and prune the exploration candidates that reach an already reached pixel. Also prune all search paths that have not reached the next screen, once every pixel on the next screen has been reached. Eventually a winning pixel will be reached and that path is an optimal Speedrun. (There may be more than 1)

[@nilskrumnack8699]

It also makes me feel bad about myself, even after doing this professionally for over a decade 🤣

Writing a game and designing one from scratch are two different things. Its like comparing a construction worker with an architect.

[@doufmech4323]

To be honest though this is a very very simple 2d game with simple physics. The only complex thing with this game is the art

Whoa, didn’t quite expect jumping into super fast build mode at 10:05, but I’m digging it 😂 Kinda fits the theme 😁

Well hello there my fellow jumpers and coders.

It's actually the super fast grind mode song, but they're very similar songs from the same artist :)

Watching the final run with the winning AI is REALLY cool. Because as the game progresses it gets more and more competent as it goes. Towards the end it starts to look deliberate rather than just random guessing.

[@yaemz123]

The reason the AI looks more competent at the end is because there are less viable pathways. In the easier early levels, there are viable pathways including stupid looking maneuvers, so it has to "look" smarter at the end, even though the attempts made to get there were as random as the earlier ones.

[@vaperjoker2326]

Dude the fact that when one AI gets to the next spot, that next generation or so swarm that spot like ants makes it so satisfyingly cool.

[@Trench_Thumb]

Seeing so many Code Bullets’ jump to one point in existence is nightmare fuel, but watching the evolution process and seeing the AI learn is fascinating. As always, a deadeye on ingenuity.

[@hotcupofchoco5529]

It looks like a swarm of frogs just jumping around it’s terrifying

[@DajuSar]

It really doesn't 'learn' just brute force its way to the top, the generation that clear the 44th floor isn't any better that the generation that clear the floor 1. If you were to put the last generation in the first floor it will fail miserably. But still an amazing video :D

[@djalexander968]

youtube unsubscribed me from when i last watched you like 2 years ago but now that im back into cellular automata i resubscribed and am probably gonna marathon every video in your channel

[@marlettohemmingsen2828]

Honestly, I kinda like this "unoptimized" approach to the AI - it plays a lot like a human, making mistakes and trying again.

[@SpydersByte]

not really, this AI is making an entirely random guess every time it takes a move, that's definitely not how humans play cuz we can actually SEE the stage, know where the platforms are, can see the exit. We're not just jumping in random directions, we're trying to reach a goal we can see. They're entirely different methods.

[@CrystalStearOfTheCas]

This is not an AI, as when presented with a new level the best "ai" will be the same as the "worst". It's a bruteforce, better-than-random, non optimized way of finding a valid sequence of inputs that will get you to the end

@@CrystalStearOfTheCas Exactly, this is not much more than a pre-recorded input sequence. It would actually be much faster to just record the player inputs and repeat.

@@CrystalStearOfTheCas MCTS or another tree search would probably be more efficient but evolutionary algorithms are still a valid AI technique
