Hey, maybe you could add a counter how many seeds are fround, so that you can see at least some progress entering more and more coords.

Hello, is there any detailed explanation or tutorial video on how to use the program?
do i just need to go to the nether, mine till find bedrock and insert it on the app?

thanks before.

When i run this program it generates tons of seeds , like this , found world seed (world_seed) . Am i supposed to check all of them whether they work or not ? It is not practical.

I downloaded executable from latest release, but after running it nothing happened. Then I built exe from source, but now only blank console showed up for a second.

The program doesn't seem to find some seeds....
For example, if you use data from the seed -9098865772979074265 the program only finds the followings ones:
-3190143061868983513, 2749823371655990055, 9094800062677759692, -3411977577506818356

I am not 100% sure about this, but what I think is happening is that the nether only uses the bottom 48 bits of the seed to generate...
So every nether has 2^16 (65,536) different overworlds that lead to it.
You can check that if you compare two of the found seeds with the one I entered, they indeed have same 48 or more lower bits.

-9098865772979074265 = 1000000110111010010101011100100110001110100111110100101100100111
-3190143061868983513 = 1101001110111010010101011100100110001110100111110100101100100111
2749823371655990055 ..= 0010011000101001010101011100100110001110100111110100101100100111

the fact the program only found two of those 65 thousand-ish seeds means, it probably doesn't work for most nether seeds...
(it finds a seed that has the same nether as the entered one, but the overworld is different)

how do you use it in linux?

Hello,
I was thinking about making a mod in Java with the same functionality...
If you don't mind, I would just like to ask what is the general idea behind the algorithm to get the "main seed" of the generator for the bedrock? I have looked at the Minecraft's code, to see how it generates the bedrock in the nether and I think I have at least surface level understanding on how it works... If I understood it correctly, the only information you are given is that
(((mainSeed ^ MathHelper.hashCode(x,y,z)) * MULTIPLY + ADD & MASK) >> 24) * (1f/(1<<24)) < HEIGHT_VALUE
where HEIGHT_VALUE is calculated based on the y coordinate and the range where the bedrock generates. And mainSeed is unknown...
The naive approach I thought of was just to go trough all 2^48 possibilities and calculate if it fits the bedrock pattern for each one, but I feel like there must be some better approach to this.
I tried to look at the source code of this repository, but I don't really understand Rust😅... I ended up going through the lib.rs and layer.rs files and it almost seems like you are discarding the 12 bottom bits and just calculating with the upper 36?
I completely understand it you don't want to answer...

System: Windows 11

I've tried both downloading the release and building from source.

The release file when running, doesn't show up any GUI and I had to kill the app from task manager.

The built app runs in as a command line and also doesn't show anything.

Rust was installed with the installation app for Windows. But building was done within the MSYS shell, I'm not sure if it could have affected anything.

whenever you load a config that was saved earlier, all of the blocks are set to "Bedrock", even if there were "Other"s. MacOS btw

bedrock_cracker-windows.exe : The term 'bedrock_cracker-windows.exe' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the

•   + CategoryInfo          : ObjectNotFound: (bedrock_cracker-windows.exe:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException
    
  

I got this issue in powershell when I have the binary and coords.txt in the same folder

OK so i got some questions first... is if i can use this on non paper servers/worlds/ so also crack the major world seed?
This is important beacause im trying to crack the seed of a famous modded german minecraft youtube project called ''Minecraft Feunde''.
The only idea i have right now it to hope that the mods dont change anything about world generation. Also the project is in 1.19.4 and i wanted to know if the cracker still works in the version? Also its a little complicated i sometimes get 18 seeds and sometimes get 0 seeds
idk if its an issue on my side probably i messed up some block placements but i got a very important question! Next to the coordinates i got the option to choose between bedrock and other and i wanted to know if bedrock is for the structure seed or if it is to help crack the bedrock so rule out more seeds by knowing which blocks cant be bedrock.. if not that could be a good thing to add (idk if thats possible) but you may be able to rule out seeds that have the bedrock pattern but if they have bedrock where there shouldnt be.(i dont think it will rule these bedrock blocks out bc it might rule out the real seed because you just enter some bedrock coords and not all(actually if this is actually how the program works that should be changed)) so yeah please if the other isnt to rule out seeds please add an option to choose for a not bedrock block!
Thx in advance!

Might be a good idea to have this thing take some sort of a file input. Maybe a condensed format that SeedcrackerX emits.

I don't understand what's happening when i open the main.rs, it's asking for a filename, but doesn't specify the path... where do i insert the coordinates?

i have installed latest version cracker_gui-x86_64-pc-windows-msvc.exe , when i opened it ,it opened a window with white screen and closed after 2-3 seconds

Does Nether Bedrock Cracker work on Ubuntu? I tried to run it on another Linux distribution but when I double clicked it nothing happened. Also in the properties it said it was an executable file.

Thanks in advance,

Jeffrey.

Because there's no specification inside the app, I had to assume the way to enter the coords is x/y/z, so the data will be like x/4/z or x/123/z?

i used both coords, but it says found 0 seed, even after pressing the crack button, and if i input too much it says "naive estimated results 0 seeds"

Hi MisterX,

At first i want to thank you for All your work! Your mods are the only reason that i am still playing minecraft!
Sounds a bit crazy, but its True :)

My Personal skills with mods and programming are none.

Is there any Chance that you are going to make the nether seed cracker as a ingame mod ore will you fix the Windows build?

Thanks

Meine Hochachtung

Is there any way to use the overworld bedrock formations to find the seed of the world? In case the server blocked your SeedCrackerX with a custom generation?
