RE: 10:15 That doesn't improve efficiency because it only routes in the direction if it's clear, meaning it'll start getting more but that'll cause it to back up so it'll stop getting them until it catches up causing it to self balance. The original Shapez did the same thing.

[@-SaKage]

It's called a manifold btw

[@KuroroSama42]

It can only more efficient in that it improves the startup. Without the balancing there can be some time spent "filling up" tracks during which the later machines aren't working. But yeah, once it's up and running, same efficiency. And the startup is pretty insignificant in this game.

[@fuj1n]

@@balt. That's exactly what causes the farlands. At high enough coordinates, the floating point inaccuracy causes the math to break down, creating nonsensical numbers for the height map. Though it's been fixed since like beta 1.8 (not the same as the more recent 1.8).

[@monad_tcp]

21:44 that's called floating point error, the father you go, the bigger the error gets. usually games keep the camera and the map positioned at 0,0,0 so that doesn't happen.

[@anonymousperson.5528]

[@KuroroSama42]

@@anonymousperson.5528 C# doesn't check for overflow by default. You can change your project settings to enable it. Or you can explicitly have it check with the "checked(var)" function. So an integer overflow could (probably) be possible. I'm not saying it's the case here.

[@HIDDEN_ORIGIN_DnB]

An integer overflow is something completely different than floating point error. Makes me think you guys shout words out into the void, hoping to sound smart to someone... If the issue was an integer overflow, then the map wouldn't be infinite but instead, well, overflow and loop back on itself. Would also be kinda cool though. But that flicker and graphics error is 100% floating point precision error!

[@K-o-R]

You left that miner built in the Far Lands. It will forever be taking a little bit of processing power.

[@mathismt1222]

Josh for "Let's Game it out" already broke it, you don't have to, RCE. The bug near 20:00 is a floating point bug. if you go far enough in shapez 2, it will start to glitch out due to the game using 32 bits to store the number. 1 for if its positive or negative. 7 for the exponent and 24 for the number. the precision worsens by 2 times every power of 2 you go far away. this is in every game that uses floats. Roblox, Minecraft,you name it. some games do use 64 bits so it is much more precise. Minecraft still has its far lands but instead of being about 12 million blocks away, it is about 53 trillion blocks away.

[@DerSolinski]

Yeah those are floating point errors... they are the enemy in any game with vast distances. Also the underlying logic is probably fine, but the rendering of the mesh instances gets real flaky if it can't put the vertices where they belong. There are ways around it, but it needs to be build for that from the get go or it will be a GIANT PITA to patch that functionality in. At those distances physic engines are real fun, they constantly find new ways to surprise you.

[@logicalfundy]

Yeah, I seem to recall they were a major problem with Kerbal Space Program development - with the simulation trying to use realistic astronomical distances, the limits of floating point numbers was was easily reached and would affect things like the physics of all of the pieces attached to the rockets. It took them a lot of work to fix all of the associated bugs, and I think they had to transition to larger (64 bit?) floating point numbers as well. This is also why many space games do things like divide space into sectors or solar systems that need a loading screen. No Man's Sky, for example, keeps planets in a solar system relatively close together, and to hop from one solar system to another you need to go through a loading screen, which allows them to always have the planets relatively close to to origin.

[@EreaserNL]

​@@logicalfundyfor Elite Dangerous they wrote their own library to use 2 single 32 bit floats to emulate a 64 bit float. From a science point of view Elite Dangerous is a super interesting game. Their StellarForge which generated the universe is sometimes even right or very close to being right when we discover new planets IRL!

[@colecube8251]

wonder why they don't just have the logic for each grid be its own thing. Like, they have a grid system, why not use it!

[@DerSolinski]

@@colecube8251 because Unity... Floating point errors with vast map sizes are 90% of the time technical debt of the established game engines since it wasn't a thing when they were conceptualized. A lot of newer engines are capable to abstract that away without you noticing but all long-standing engines have options/tools you actively need to opt in. And if you forget that you'll have a lot of work to remedy that. The solution is quite simple and requires chunking / partitioning your world to keep floating point errors negligible but every thing else needs to be able to handle that.

[@colecube8251]

@@DerSolinski So, let's say each grid space has 200x200 squares. Would it not be possible to have each grid have data for what's inside of it. Then you could just use a 2d array to load in the grid, and use a 2d array to load in the squares of the grid... right? This wouldn't have any rounding errors since there is no need to use floating point numbers. And as for rendering, just have the camera stay at 0,0,0 and have the world move around it inversely. Is there a reason this wouldn't work? I've never used unity and am a very inexperienced programmer. If I had to guess this *is* possible but perhaps this issue was realized to late into development to be fixed easily?

@@urkerab I found it better to upgrade the belts first/more than the rest. The belts are the ultimate limit on how many resources you can mine/move. Space wasn't a huge concern for a while at least, so needing fewer machines isn't as important as getting more resources in/out. ... didn't realize the game had a "number per belt" thing though. I was just dividing the "#/m" of the belt by the "#/m" of the machine. 180/m divided by 45/m is easy: 4.

19:36 playing with paddy montage 19:49 end of montage

[@jbird_623]

The reason all the shapes at the edge of the universe are wonky is because of a little thing called "floating point imprecision". (I'm simplifying a bit here but) basically what's happening is that the computer only has so many digits it can use to represent a decimal number, so the more numbers you have *before* the decimal point, the fewer you can have *after* it. What that means practically is that the numbers stop being able to be precise enough to draw correctly after a point, and so the further out you get from the center, the harder a time the system has zooming in. Moving the camera starts changing how the decimals are being rounded and makes the details on objects start to be drawn differently depending on very small changes to the camera's position.

[@TitoRigatoni]

@@DennouNeko Protip: Just consider pins to be a separate shape. So your MAM brings in complete circles, rectangles, stars, diamonds, and pins. Then just cut and arrange them like any other shape. You'll need to make a small separate factory to make a shape with just four pins.

[@DennouNeko]

@@TitoRigatoni Uhm... You can't really make a 1-layer shape with just pins in Shapez 2 since there's no unstacker (at least at the moment). And I know the logic needed to detect a pin layer and add it under a higher layer. Even with pins that slide down to bottom layers on stacking if a piece below is missing. But with how slow the game got at this point I simply couldn't be bothered with modifying the modules...

When you go really far in most game engines, the engine still needs to know where you are. So, it uses a floating point number- like scientific notation. But, that means it has limited accuracy at long distances, because there arent enough bits to store the number in it's entirety. That's why so many games have shakey models a long way from the centre of the world - the model is so far that the computer can't accurately place each corner because their position data is so innacurate
