Software Dev Reacts to Let's Game It Out Build a Nuclear Air Force in Hydroneer

Happy Holidays! 😁 Let's game it out keeps surprising me even when I know it's coming lol. Plus, as a software developer, it's really fun trying to figure out how he breaks the game so bad. So today, we're reacting to Let's Game It Out's video, "I Set Off So Many Nukes It Ended Reality in Hydroneer!" If you haven't seen it yet, please watch it here FIRST: • I Set Off So Many Nuke...

[@emmetmichigan8188]

For the cart, same glitch, but the cart provides velocity which allowed it to fly in control.

[@emmetmichigan8188]

And when game resets, the velocity is set to zero

[@Bingle1]

I've done a bit of game development myself and i have a couple of ideas as far as the carts flying around. I'm guessing when an object is placed on top of another object, it's made static, moves with the other object, and collision is disabled between the two objects. In this case, I think that collision is disabled between the cart and the pallet and that collision is disabled between the item on the pallet and the pallet, but not between the item on the pallet and the cart. Since the cart is dynamic and the object attached to it and constantly colliding with it is static, that produces a constant force that makes the cart go crazy.

[@Krakenfall]

Oh, that makes sense. It puts the object and cart collision boxes slightly within each other, causing the repulsive velocity. Then, the speed would be determined by the amount of collision box overlap. The cart is faster because the overlap is probably greater. Good call!

[@Karatemaster-fq5pi]

@@abiean222 idk tbh but I was just amazed I understood what they said like I wouldn’t understand the problem as code but the I guess in the “in game” way that someone like josh tests the game is how I understood it that and I actually have something else for the theory why this happens So objects in hydroneer actually have very odd hit boxes they aren’t completely flat on what is visual kind of like a carpet of spikes or something around the item which is why say when josh or the player runs into an object not “placed” or used in the build menu/ dropped the object looks like it has been kicked or something and since each item has a different shape like the pipes more or less of those “spikes” are colliding with the cart as Kracken said but instead of how much hit box there is I also think how many of those spikes though they would also cause the crazy velocity I think the spikes kind of cause direction because item like the bookcase/ shelf only flew away from the cart though it did turn when it hit another object it didn’t go absolutely ballistic when something like the nuke was being used

Good code quality just makes Josh have to do more to break it. Perfect code isn't real, Josh will find what breaks it, it might just take a lot

A tester test stuff for the purpose of finding and fixing flaws. Josh test things with the purpose of generating the maximum amount of chaos possible, and a few crimes against humanity if possible. Josh is the fifth Chaos God. Khorne, Slaneesh, Nurgle, Tzeentch and Josh.

"Not going to judge their code" Considering this velocity is only happening because of a very strange bug, I think we could forgive the code for not being able to handle what looks like hundreds of collisions a second, since it's not supposed to be happening like that in the first place.

[@jem5636]

Krakenfall, I have a horrible confession. For the very first time, I watched your video before watching Josh's. I will now make up for my crime by watching his video.

[@bluestar_kun]

8:15 he might think like a tester but as they say "curiosity killed the cat... and gave LGIO entertainment"

[@confused159]

Honestly I love your reactions to Let's Game It Outs game breaking videos

[@michaelwulfbane]

I figure Josh has some of the push the limits testing mindset but since he’s doing it for entertainment purposes, if he doesn’t get amusing results, he can just move on. Sure he’s pushing into corner cases and discovering unexpected interactions among multiple systems, but he isn’t tasked with verifying ALL possible combinations or trying to pinpoint what systems are going wrong.

[@Krakenfall]

That's a good point. I've fought some nasty bugs before that just won't die. That wasn't fun.

[@LastKnight0727]

I have a feeling if Josh was a tester he'd find the fun stuff, never report it, and just report the things that completely break the game.

[@Raida7]

Cat cam 😄 And just the right amount of analysis and fun in watching LGIO

[@LordRazer3]

10:04 it's body collision. The character, pallet, and card are always constant. If you look you will see that whenever he gets off the cart the character pops up on top of the handles...but if there's a pallet in the way the game has to make a choice on what to move and in this case it's that cart. Why it flips out is not something I wouldn't know but the easy fix would be to just add no clipping to the card handles

[@jenniferlizbeth1830]

He did the same thing (trench with explosives) in Astroneer of course he dug the trench around the entire planet.....

[@GamerXenith]

This is one of my favorite videos of his 😂 The flying carts and Josh's reactions are so hilarious

[@skittycat213]

When you were talking about the problems of high velocity in games that reminded me of one of the things I encountered in the Forza Motorsport franchise where certain parts of the track wouldn’t be able to load/render in fast enough by the time you were driving over them, resulting in you driving over an invisible track

[@jiggermole]

Like you I like watching Josh because he seems to genuinely have fun doing this stuff. Not just a little fun, genuine glee based on the fun he has.

[@AreeyaKKC]

He just released a new hydroneer yesterday. It's hilarious

[@krispyking2450]

[@ca.b.92]

What you are telling about ticks and calculations, with going through a wall sounds like the youtuber DocM77 did on the HErmitcraft server: Accelerationg an arrow to about 1000 blocks per tick, then shot it in the direction of an enderman, to make it fly through almost 1000 blocks of solid minecraft world, because the calculation already did one colision test in that tick.

[@willylestupid4440]

6:50 The best explaination i got is, The Pallet is trying to Grab the cart, And the cart is trying to grab the pallet so since it will always change the position it will glitch and make it fly

[@maxaquino1971]

Consider the "subscribe button" licked. Unrelated sidebar: I'm no longer allowed in this library.

[@travislapham3479]

What is really happening is that the pallet bug still hasn't been fixed and whenever something hits something else really hard and fast it'll create a hole for a few seconds and then fixes itself and then continues until the game slows down to a point where the game crashes

[@annakaro9081]

I love the cat cam 😂

[@MoreZ0K.1]

I remember this stream, the ending qas so oddly satisfying

[@pyroman7550]

First video I have ever watched from this guy, and he has a cat cam, for when he is petting his cat, W man

[@WolfRose11]

It looks like the pallet is attaching to the cart which is attaching to the pallet. So each time the pallet updates position it updates the cart position which updates the pallet in an endless cycle.

[@Suthriel]

Regarding those fast moving objects and collision checks, wasn´t there a way to prevent those skipped collisions? I once read something about objects checking not only if they collide at their current position, but if there would be a collision in their path from the position from the last frame to their position in the current frame. So if there was an object in that path because the object moved to fast, then the game would set it back to that position, where it should have happened between those frames.

[@nikkiofthevalley]

Yes, that is possible, but intensive to do, as raycast-mesh collisions happening every frame for every single moving object is not something the CPU likes.

[@Oshroth]

Yes, there are two ways of doing collision handling: Discrete and Continuous collision detection. Discrete collision detection checks on each frame to see if an object is intersecting with another object at its position, but if an object is moving fast enough (as shown in this video) it's possible for it to move through other objects. The other method is Continuous collision detection, which involves casting rays for each object as it moves to prevent it from passing through another object. However the downside is that this physics system requires way more calculations and a more powerful system to run effectively, so most games use Discrete as it is usually good enough for 99% of cases. I've also seen some games use a Stepped Discrete system to provide more accurate collisions without needing full Continuous detection. e.g. Super Mario 64 uses a 4 step Discrete collision detection for Mario. The game will check each quarter step of Mario's movement for collisions

[@Shasta--1]

[@samdavies2069]

Beautiful migration of a murder of carts

[@zxuiji]

the fix for the group collision is as simple as attaching another part to the carts etc that gets reconstructed each time items are added/removed, then the items themselves are partially deleted, just their details like weight etc is recorded in a list attached the carts etc, that way only the collision for the carts etc and their reconstructed static parts are processed. As for the explosions, the simplest performance solution is to just set a limit to the chain reaction, beyond that just treat it all as one big explosion

[@Dragongaga]

The fast moving carts inside the box wouldn't slow the game down, because the rate at which the collisions register is still the same, but as far as I know from my experience with vertex handling and collision detection (Clonk Rage, look it up) there's no way for a game engine to know if two objects collide with each other multiple times per tick, unless the developer specifically gave it the ability to, so there's a limited amount of collisions per tick that can happen inside the box (and that btw is the difference between a quantized universe with finite precision and a continuous universe with infinite precision. We live in the former and so do game engines). I'm guessing that the game crashed the second time due to a floating point or overflow error, like the collisions in confined space caused the carts to move faster than the engine can mathematically resolve and it crashed. The first crash with the nuke was probably a null pointer exception, as in, a cart tried to collide with a tile that blew up during the same tick or the one before, the collision handler tried to grab data that was no longer available and the devs didn't account for that to happen (because it's a weird, unlikely precedent, so I don't blame them) I could be completely wrong, but that's my take on this.
