Software Dev Reacts to Let's Game It Out Steal ALL THE PIPES 

If you're just here to see the cat (Hobbes), watch until the end 😁

Let’s Game it out can be described by this sentence. “Am I going overboard? No! I’m not going overboard enough! I will go extra overboard!”

"I'm scared to see what his toaster looks like" I'd bet you Josh microwaves his bread

Josh explained on his Twitch he has macros and auto clickers to set some of these weird things up like for fishing. Then he just leaves the game running over night. But for others things like building giant Tornados that he does himself. Basically if it's a repetitive consistent task he'll automate it depending on how far he wants to go. Also he gave you a call out in that same stream, cheers!

it wasnt that the last row worked better, its that in the second test he only used the last row; to save the frame rate.

9:30 While he is explaining, I was not paying attention but doing what anyone would: watching the cute cat playing

Fun Let's Game It Out fact: His personal record RAM ever used on his computer was (I think) 38+ gigabytes. It was achieved using thousands upon thousands of fireworks in Planet Coaster, so much to the point the game didn't render them because they were out of distance.

16:45 "What is he doing, this is legitimate" 20 seconds later. "Stunned silence" How every Let's game it Out goes.

8:08 “i wanna make an art installation with objects in the air” oh well you’re in for a treat my friend 😂😂😂

The funniest episode is the one with carts, that one has the most wild physics I've ever seen

Needed to rewatch your explanation for the flying truck at 10 mins twice since the first time i was just too focused on the Cat in the back. Keep it up!😂

17:25 This is my favorite part. After a while, you build up some pretty high expectation for Josh's insanity, but he always manages to exceed them. > builds 10 machines > "I'm going to build a few more of them" I'm sure he's going to build like 200 > builds 2000

I love that while you were talking about the bug with the trucks and the pallets, you could see someone playing with the cat. Pro tip: peacock feathers are great cat toys. You can wiggle them against the ground or different things, and if the surface is hard the rib of it will make a scritching noise that grabs cats' attention.

If you were to consider the Pallets/Truck and the stuff stacked on them in a hierarchy, described as a tree such that: - The Base is at the bottom of the stack, say the first pallet on the ground or the truck - The first branches are sitting on the Base - The second branches are sitting on the first branches - etc... The bugged collisions would probably be third branches colliding with first branches (not including the first branch they are attached to) or the Base (in the case of the truck) So when you place a pallet on a pallet on a pallet, the items on the third pallet collide with the other items on the first pallet. To sort this out, you either need to recursively check for branched attachments to diable collisions, or as you suggested prevent any double-layer (or more) attaching. As for how the object moves during a bugged collision, my best guess would be that the object is trying to un-stuck itself and move outside of the colliding object. This doesn't work because the colliding object is attached and moves as well, resulting in this un-stuck movement being applied every frame.

I heard a rumor that Let's Game it Out's house heater broke and he maxes out the games to turn his computer into a space heater.

Josh's games measured in seconds per frame

the truck demon was originally far more prevalent. it was (maybe still is) caused by the tractor tires, they have collision boxes, as does the tractor body, and the suspension "simulates" being weighed down. so when enough weight presses those two collision boxes together, they can't split because the tire has hard limits on its movement but can't escape the truck collision mesh. several versions ago the truck would do this at the drop of a hat whenever you even clipped a rock or debris while driving. nowadays its actually pretty rare unless your specifically trying to glitch the truck

I've never ceased to be amazed by all the work that Josh puts into avoiding work.

The best/funniest episode of hydroneer is "I set off so many nukes it ended reality in hydroneer." For reasons not at all pertaining to nukes.

Him: explaining a complicated game mechanic. Me: Hobbs looks like he's having fun with another human back there

Can we get a "Krakenfall Reacts to Hobbs getting all the scritches?"

All of us (josh's fans) LOVE seeing other people's guttural reactions to his madness

21:25 I think it wasn't anything about the individual rows, he just needed to remove basically all drills - except for a single row - for the game to be even partially playable. Before the change, every single drill in that setup did its thing. I must say: I like a lot about Hydroneer, but for a game that's about automation, it's really poorly optimized (at least in those builds) to handle those physics-objects. Once you get past the early stage of digging and washing by hand, you'll naturally have more and more automation with physics-objects falling everywhere and if the game can't handle that, then that's a pretty fundamental flaw. :-\

I really like this channel. You've inspired me to play Satisfactory again for the first time in a year, and I haven't been able to stop.

Fun Fact: In Hydroneer, one of the towns has a sign: WANTED Let's Game It Out REWARD c1,000,000,000

Hydroneer is multiplayer except they couldn't get online multiplayer to work so instead it's split screen local with remote play.

Josh's planet zoo videos are his funniest imo, but it isn't really a similar type of game to what you've been watching so I'm not sure if you'd have quite as much to say about them.

LGIO probably hasn't made a single video that I wouldn't want a reaction to. Planet Coaster and Planet Zoo are probably my favorites, but let's say the latter might trigger some lizard doggo PTSD. If you're looking for something completely different, you might wanna watch Internet Historian's Fall of 76 or The Engoodening of No Man's Sky. They're a bit longer, but I have a feeling you'd appreciate them from a software (& bugs) perspective. Can't wait to catch your next stream.

I love your reaction videos, you talk about the technical aspect about the bug Josh exploit

The developer of hydroneer is working on a multiplayer format. He has a small video about it on steam

I can't wait to see Hobbes, and the vid of course but mainly Hobbes

wait did we have kraken the editor in front of kraken the kat skractcher, talking about stuff while having the original kraken paused? krakenception!

when you were explaining the floating truck i spaced out and focused on your cat

wait until you see pallets on carts... its magical

I feel like you have been blessed by the RU-vid Algorithmn because up until a month ago i didnt even know your channel existed and then all of a sudden i see a video of you on my recommended list. Honestly best thing that has happened to me. Love your Videos and your cat. I hope you get the recognition you deserve because i think you have a unique way of organizing stuff in Games and in general and i love it. Wish you all the best and greetings from austria :)

The cat’s cool, but I’m totally here for your brain going wtf as let’s game it out destroys the game.

I love how your significant other/roommate is playing with the cat while editor kraken was talking

When Josh puts that card up that says "11 Hours Later" he means it.

Omg I love game grumps, my favourite lets play of theirs was super metroid, every year I boot up my snes and play along side them and enjoy the nostalgia

Your videos are never boring, keep up the good work!

He always goes the extra 4 parallel universes

The truck is a buyable object, which can be attached to the pallet. The pallets can be attached to other pallets. The pipes can also be attached to pallets. Each item has collision as well, but no clips when on a single pallet. Using 2 pallets, everything is colliding and causing forced movement outside of its space

I've been hoping for more explanation since I watch for the game dev reacts part... you did awesome bro!! Love your explanations

Loving your reactions man, love the chill beats you have in the back too! Keep doing what you enjoy, we love the reactions for the personality man

Started watching about a month ago, the watching let's game it out got me, your personality and games you enjoy got me to stay, keep it up and keep being you.

I want to say thank you for linking to the video you are reacting to. Far to many reactions give credit in words but can't be bothered to provide a link to those that let them do the reaction.

Can’t wait for this vid

I love your reaction to lets game it out, also I'm a software developer in Seattle, WA . Keep up the great work

I love your reaction to the scale of Josh's insanity. That's what makes it worth watching. Welcome to "Let's Game It Out"!

I like to watch Let's game it out. His hijinks are always funny. And if you look past his shenanigans, you can see what the game is like. He's the reason I got Hydroneer, though I don't try to break the game.

8:24 man the cat is loving the scritches

Honestly the single fact that your a fan of game grumps just earned you a subscriber

So I just found justgameitout and yourself. You’re both legends. Keep up the good work

About all those shenanigans Josh experienced with flying truck and palettes filled with objects..That is not just due to Hydroneer being an early access game. In fact it has to do by which physics engine Hydroneer is using. Since Hydroneer is made with Unity game engine I'm guessing it is also using the default Physics engine that comes with unity and that is PhysX. So why is this bad? That is because PhysX is using so called single stage physics simulation. What does that mean? That means that as soon as physics engine manages to calculate forces that are acting to a specific object ti moves that object to a new position based on those forces and then proceeds calculating forces for the next object which is bad. Why is it bad? Because as soon as you have moved your first object to a new position the forces between the first object and some other object that it might have been in contact have changed. This means that the physical simulation longer follows the Newtons third law that states that if object A is acting with certain force to object B then object B is is also acting with same but opposite force to the object A. This erroneous physical calculation gets more noticeable when you have many objects interacting with each other and generally increase with the number of objects piled up. That is why you tend to see bigger piles of objects constantly jitering or spontaneously launching into air. And the thing gets a lot worse when you have multiple objects connected to each other in cyclical way. Like A connects to B, B connects to C, C connects to D and then D connects back to A. Quite often when you have objects connected in cyclical way in PhysX simulation goes haywire. Many people started calling such scenario as "Encountering the Kraken". The solution to avoid such problems is to use physical engine that uses two stage approach where in first stage it calculates all the physical forces for each object similar as single stage simulation but instead of moving the object right away it saves the future position of the object into memory. Only when forces for all objects have been calculated does the simulation actually proceeds moving these objects to new position. The main advantage of such approach is accurate physical simulation. But main disadvantage is that you are basically doubling the memory required by the simulation. And it does involves some additional processing. Sorry for long comment but it can't explain this in shorter form. And I can no longer find an old video where one of the Microsoft programmers that worked on first Forza game explained this in much greater detail.

As a hobbyist game developer, the issue is more likely simply that the palette's hitbox and the truck's hitbox overlapped, and the items placed in the truck are parented to it, think of it like glued to each other. So the physics engine is trying to push the objects away from each other but can't, causing a constant impulse force. I don't think it has much to do with multiple palettes specifically, just that the palettes are large and are relatively easy to have clip into the truck's hitbox. The time the three palettes went flying on their own was likely for the same reason, the hitboxes of them probably were overlapping. The truck probably has it's rigidbody velocity locked when the player isn't inside of it to prevent it from being moved. In most game engines you can parent an object to another object, this effectively makes their position relative to that other object, so when the parent object moves the child object does as well. If in addition you lock the position then you stick the object to the other object at a fixed position and rotation. It's very common for this bug to occur in games, and especially during development. When parenting objects it's recommended to disable the collision or preferably the physics entirely for the child objects, if the engine supports it the parent object should instead use a composite collider which will make the parent object act as if its hitbox is the sum of itself and all it's children, but the child objects themselves have no physics by themselves. But this can be very easy to forget to do. The number of times I've had my player character pickup an item that I then set to show in the character's hands, only to have it cause the player to gain the ability of flight, is more than I can count.

Ok but the part where your explaining the pallets and truck all I was paying attention too was the kitty in the background getting love

I am loving the background battle around the 9-10 minute mark. =]

You were really nice in the intro, you have gotten my subscription🎉

Very good video. Much good cat. Much good reactions and speculation about glitches.

the disclaimer man he actually sounds like one of those people who says the fine print super fast at the end of these medicine commercials

I love hearing the insight into why you think the truck was floating!

After watching LGIO's series of Hydroneer vids, I finally decided to pick the game up a few weeks ago. It's definitely the sort of thing I enjoy, similar to Satisfactory, Stationeers, Factorio, etc. However, while I like Hydroneer, and look forward to where they take it, right now it felt a little lacking in something. Not sure what, but I think it needs more content and things to do, and more motivation for the work involved in setting processes up. In Stationeers and Satisfactory, you always seem to have some new project to pursue or thing to explore. Hydroneer doesn't seem to have that level of depth (YET). But, I think it will get there one day! Also, yes, all of the tummy rubs and chin scritches to Hobbes!

I think it was Hydroneer and similar to his truck god and pallet demon, Josh sent what seemed like hundreds of wagons loaded with pallets and items flying thru the air and i mean FLYING fast, think any kind of sci-fi movies flying traffic, it was so entertaining lol.

I It just me or when he was talking about the floating truck. All I was paying attention to was the adorable day in the background. Also I love your videos.

I suggest reacting to 'Real Civil Engineer'. He has hilarious commentary, and like josh as a... tendency... in his building projects. He like bridges. Anything, a ship, a building, a vehicle, will eventually be sued to make a bridge. And yes, he also did some Hydroneer videos

I love the petting the cat in the background during editing the video 😍

8:35 bonus points for fitting in a Hobbes petting.

given what i've seen in other hydroneer vids, the glitching truck issue is when you stack a pallet so that the items on it poke into the truck's collision mesh. it can happen without a pallet. sometimes it even happens when you hit a wall wrong. it seems worse when pallets are involved, my guess it's because the pallet keeps pulling the item into the collision mesh, meaning the truck reacts to constant small collisions, that the physics can only resolve as coming from inside the truck, pushing it in a random direction, which can make for some interesting pinball physics

Josh always find his own way to get in the closed bar and blow it up with fried rice

Great video and I love the reactions, two great channels/ creators I like

if you think him having the patience to put down that many drills is impressive then you should really see the things that he builds in planet zoo and planet coaster

this is amazing, more devs should do this, also watching this while playing hydroneer

love the reactions keep it up!

Great videos! They make my day when I see them

Dude, I don't really like reviews or reactions, but this dude makes it worth while to watch, really fun

krakenfall: complexly explaining why the truck was gliching in the backround: random person playing with his cat.

9:00 Who is this silly person petting Mr. Hobbes🥰 in the back round 🤔

Don't you just love how much automation Josh sets up? With Josh, there's no such thing as overkill because he's very much aware that there *IS* such a thing as underkill.

Want to know how he does it, for most of us we just kinda feel like he plays the game sleep deprived slowly sinking into insanity while finding ways to break the game or frame rate in the many creative ways that he can find :3

9:10 peep the adorable kitty getting loves ❤️

If josh's computer (64gb ram) dies this much, i believe my pc can become a tactical warhead if i do this

9:00 I couldn’t focus on anything other than the cat

I absolutely love Lets Game It Out and the Hydroneer series is one of my favorites. This is great.

the cat in the background at 10:00 is adorable.

Let’s game it out has sent a bunch of in the sky and just let it fly around

I discovered Josh shortly after his partner went off to do something else. I've shared some of them with My Favorite Daughter and we both get a LOT of laughs out of his videos. I'm glad you've discovered them. Also, was fun seeing kitty getting scritches in the background. You might want to explore DarkViperAU's videos for GTAv where he does things like no hit runs and passivist runs. Those are some interesting challenges and he finds fun ways to break the game.

9:20 - I think it's the pallet trying to get stuck into the vehicle then it collides, tries to move away but it's fixed at the truck so it collides again and jitter happens

Ooh it’s so cool that you’ve got a plausible theory of what happened with the pallet to make the sleep paralysis demon!

I'm not a game designer but I am a software engineer. What I think is happening with the pallet(s) is that when things are placed in the truck or on pallets, their collision physics is "turned off". Which is to say, their acceleration is set to 0 or their position relative to their container is fixed. But the actual collision isn't disabled. So even though the components don't move, they keep having tiny collisions with the truck and each other. All those "0 speed" collisions keep accumulating every physics tick and the rounding errors accumulate creating motion. Also the n^2 collisions from all of these overlapping items in the back of the truck overload the physics engine, so it probably starts doing coarser time steps to compensate. This also causes those tiny nudges from colliding objects to be exaggerated. We see them stay in place, but what the physics engine sees is them bumping each other, moving, bumping the truck and then having their position snapped back to the truck's reference frame. I've pointed this out in other places, but the software engineer(s?) for this game doesn't fix problems at their root cause. They see a problem, they apply a patch to fix the symptom. Like when Josh stole items by putting them on the truck. The sensible strategy would be to add meta data that persists through saves, and marks the item as not owned. But in this game, the item is just deleted if it's placed on a truck or if the player, rather than the item, is outside of the store boundary. In a good game, each entity would be part of a different physics category: Items that have full collision. Items that only collide with X. Items locked to a container. Items locked to a belt. Etc. Then the physics loop would go through each of those lists and check them accordingly. But in this game everything is treated the same and then exceptions are applied later. It might be a limit of trying to work with Unreal engine without overhauling the physics. But I think for a game with such specialised physics, an overhaul is appropriate. There can be literally millions of entities being simulated at a time. They can't all be generic physics objects.

Dude I subbed 30 seconds into the video you just seem so nice keep it up

11:00 As a game developer, let me explain. The game is created using the Unreal Engine, which includes a built-in physics engine that calculates collisions and more. In the game, you can interact with objects by pushing them around. To achieve this, you typically place a "Rigid Body" component on the object. This component provides the object with standard collision and physics properties. I believe that all objects loaded onto the pallet become one with the pallet object which has no effect. However, when another pallet is placed in the pallet, the Rigid Bodies of both objects collide and push against each other. At this moment, the physics engine attempts to separate the objects due to the collision, which causes the glitching. The same goes for the truck it also has a Rigid body or something comparable.

The floating/spinning/flying truck/pallets is caused by hit box collisions not resolving. The physics of the game says: if pipe A collides with pipe B, move pipes. But game says, if pipe is placed on pallet, pipe sticks to pallet and doesn't move. Now insert pallet into pallet, which is what happens when he managed to shove the pallet into the stack pipes on the pallet that was already there. Now pipe A collides with pipe B and the game tries to move them apart.... but pipe A and pipe B are attached to pallets that themselves are locking them in place and any movement just results in more collisions. The game keeps trying to resolve the collisions but they are really unable to resolve, so the game just keeps trying to move them, but any movement is just back into a collision. Rinse repeat ad infinitum and you get wild and crazy stuff. You can do this is Space Engineers to some really great and sometimes catastrophic effects by causing objects to collide in ways that the collision can not be resolved.

we got you on the subs!

Josh previously played with a friend who he also ran the channel with. They parted ways. Said friend was the only thing keeping Josh's inner demon at bay, but now that he is gone, Josh can do whatever he wants for however long, which is why most of his Videos now are so chaotic

As far as the truck/player connection is concerned. I'm betting the truck may just be a modified player object which would make sense as to why items can no longer interact with the truck outside of the store if they haven't been purchased. Would also explain why you can't pallet a truck/player. Definitely possible some other logic is handling those interactions. That's just the simplest explanation I could come up with. Also, Josh makes the most hilarious videos(I've watched all of them). As a Software Developer this man is my worst nightmare.

"OH!" And there it is folks.

Extra mile? No. Extra lightyear? I think that may be approaching Josh's mentality.

He went from 600 drills to maybe 60 running at the same time. Not to mention every conveyer is water powered, so all those rows of conveyer belts were shut off as well as any collision/movement of rocks

"To much work josh are you ok" Those are the exact words when i saw this video on his channel

Awesome we needed this
