A lag spike every time glass was updated would be really inconvenient, so it's offloaded to a different thread Why it ends up forcing the main game itself to split threads, that's probably just a really weird bug that nobody could be expected to notice since it's such an edge case that it would never be tested

so the way you get creative items in survival minecraft is *literally* alchemy. Transmute lava into water by adding some anvil while doing some ritual with a massive amounts of observers and beacons, then add something else to that while doing stuff with a piston and presto.

This is like a Minecraft research team, seeing how in depth this goes into the structure of the game itself

"The server didn't crash, that's a weird result, but i'll accept it"

I highly recommend you all watch Myren Eario’s entire series on the falling block project. Despite the implication of this server tour explanation being the ‘simplified’ one, the explanation on Myrens channel is 1000 times simpler and more coherent than this one. There is a proper full script and it builds up each concept right from the most basic level of minecraft understanding, unlike the bombardment of specialised vocab in this video.

Wow, yesterday I have just finished reading Inheritance and now there is a video with Christopher Paolini himself 😅

So let me see if I understood you correctly about how you got the command blocks initially. You created an observer line that blinked faster than the time required for one block to programmatically be converted to another block so that instead of returning the block designated in the code, it returns a spliced bitmap that turns out to equal a command block? That must have taken an insane amount of experimentation to dial in that observer line. What's your method for that?

Myrens mic is legend old as scicraft itself…

That’s an awesome explanation of multithreaded processing, I’ll go a little bit more in detail. Most computer CPU’s these days have multiple cores, and what this means is that it essentially has multiple CPU’s in one. The motherboard connects to it in the same way but under the hood there are multiple single core processors that can all do things separately at the same time. Classically, code is executed line by line in a linear fashion. The computer executes line one, then line two, then three, etc. always in linear order. With multithreaded programming, you can actually specify a chunk of code or “function” to be handled by a separate thread. While the main thread is doing it’s own thing, the other thread can run at the same time on a different core. If your computer can’t process the necessary number of threads then it’ll sorta pause some of them for a bit, run a few lines on the first threads, then switch to processing the paused ones, and go back and forth. In well written multithreaded code, we set up locks on certain pieces of information that multiple threads might want to access. If two threads want to access the same piece of information simultaneously, there’s a chance they don’t work together correctly and we get an incorrect end state. For example, we have some number x=0 and each thread is supposed to take that number and add 1 to it. If we have 2 threads, naturally we’d expect the end to be x=2, but if both threads work at the same time then they both see x=0 and both change it to x=1 at the same time, so we don’t get x=2. By “locking” that value when one thread is using it and forcing the other threads to wait for it to “unlock” we get a more linear style of code. In the case of Minecraft, it wasn’t coded to be multithreaded so shouldn’t be facing this issue of two threads changing data at the same time, but they’ve found a way to force the computer to handle the game in multiple threads thus causing an error because there was no locking system put in place.

The single vs multi thread explanation was great!

Next video: elrichmc in scicraft

Omg ElRichMC is there

This was actually something I always wanted somebody to do for a while

these guys are so epic, they even get lag to do work for them

I actually half understand the block corruption part 😁 only thing is If water is 000000 And Anvil is 111111 And command block is 110000 Then you need to select the first two bits from the anvil and append the last four bits from the water, it seems. That's quite specific. What stops the bits from being randomly selected? E.g. I could do the thing but the resulting bits would be anything but 110000 101101, 111000.. basically any of the other 2^n-1 values that could exist.

The number writes are "atomic", meaning they can't be interrupted. But in some cases, the block id is split between two numbers. Those two numbers are not necessarily written in the correct order. So you only get a *single* split in your block id.

Well that does happen. In the process of making command blocks they get other blocks too, such as wood. Then again, sometimes the corruption doesn't work and doesn't make anything, and they'll have to replace the anvil. The chance that they get the command block is low, but not impossible. That's why they said the process usually takes anywhere from 5 minutes to an hour and a half. It's a complicated process, but as long as you don't reload the chunks and cause the game to crash, the process is simple.

"What stops the bits from being randomly selected?" It depends on the relative position within the subchunk. If you replace water by anvil at x=9,z=12 while having async observers blinking next to it in +x direction you get command block. If you do the same thing at x=8, z=13 you get quartz ore instead. Also with this bug if you combine 000000 and 111111 there are only five possible outcomes: 000001, 000011, 000111, 001111 and 011111. There is no position where any other combination would happen.

My very humble guess is that the thread that reads which block there should be, does so bit by bit from left to right. So the thread starts reading it will pick up 11, but then on another thread the replacement of the water with the anvil gets resolved, during which time the reading thread is paused (if I understood multithreading correctly it doesn't actually run all threads at once, but rather executes a small portion of one thread, then running a small portion of the next thread and so on, until all threads are resolved. This way if the task of one thread can be computed quickly, it will be completed without having to wait for the completion of all the tasks in all threads). So then in another thread the replacement of the water with the anvil is executed and then the reading thread continues by reading the 0000 of the anvil and resolves in the output 110000. As I said, this is just a hypothesis at best. Not even that, it's a blind guess.

Honey a new scicraft video dropped , no shopping

Christopher Paolini?? I absolutely loved his books, but never knew he would be a guest in a Scicraft video. A surprise certainly, but a welcome one :)

This is interesting, it feels like I am in my Embedded System course in my uni again lmao

I'm a beginning game developer and just seeing how you guys figure out ways to use 'flaws' in the code of a game like Minecraft scares me 😆 There will never be a way to make a game without any glitches or flaws but on the otherhand its also inspiring how people get so commited to finding and abusing these flaws

To be fair, few games give the players as much control as minecraft does, as well as the amount of interactions that are possible in this game just probably won’t happen in most games, lol. Doesn’t mean they can’t be completely broken, still, hahaha

Now they have another indestructible block

"/fill a perimeter" has to be one of my favourite commands

I’d like to think that there is a group of friends in a type 3 civ, and they are doing this type of stuff with their own solar system. Creating mini black holes, zero point energy, quark foam, anti gravity. They’ve figured out the source code
