I've been messing around with an idea for a mod that basically makes Minecraft RNG fully deterministic for reliability testing.

The problem with testing farms or other long running builds right now is that Minecraft's RNG isn't reproducible like it is with world gen. It pulls from things like system time and other state, so if you tick sprint a farm until it breaks, you can't just reload the world and expect the exact same failure to happen again anytime soon.

The idea is to change that.

While tick sprinting, the mod could periodically save snapshots of the world. If something breaks 300 hours into a test, you load the latest snapshot and hit play. The exact same RNG sequence happens again, and the farm fails in the exact same way. I'm sure you know that the RNG system influences everything from mob spawning positions and timings to angles that droppers shoot out items.

Everything is saved in a snapshot from scheduled ticks, subticks, subtick ordering, etc which all get restored when you load that up. Except now you're in the actual world instead of digging through a very big and long Flashback recording. You can pause before the failure, inspect anything you want, run commands, change things, test fixes, etc.

You could even send the snapshot to someone else and they'd be able to reproduce the exact same failure on their machine.

I've played around with this and had some small success, but I'm not sure how far I want to take it. Making everything deterministic would be a pretty huge undertaking for what is probably a very niche tool, especially since this is only mostly useful for long-running farm tests.

Still, being able to turn a "1 in 200 hours" farm failure into a 100% reproducible thing seems nice.

Would any of you actually use something like this?

in my server there are sort of factions (some people group others don’t) but since I’m not in one I’ve gotten my base raided several times. But because I’m the only PC player with a decently strong PC I came up with an idea using hundreds of pistons to move hundreds of blocks over and over again very fast to create lag, enough lag that if any of them got to close to my base or attempted to raid it they would crash due to being on a console. Would this work if I made many machines into a wall so no one could ever raid me again.

A long time ago, ZipKrowd's members were a reference when it came to technical Minecraft. Then came ilmango with SciCraft.

I just came back to Minecraft after years away, and it seems like all the creators I used to follow have stopped playing.

Nowadays, who are the references when it comes to technical innovations in Minecraft?

Let me start by saying I know very little about storage tech. So after following this community for a little bit, I've become genuinely curious, what is currently the most popular shulker loader design? Like what design should I be comparing to all of worm's designs as like a baseline to see if they are actually an improvement?

I haven't really dived into sculk sensors or vibration mechanics so I want to get some more exposure with them.

What are some good applications to incorporate sculk sensors in a survival world?

I'm looking for something that is actually useful or complex, I'm not really interested things like wireless piston doors.

Also what are some pros and cons when using the vibrations mechanic or even just general information to keep in mind?

Hey guys, my names Beja. Some might know me from my time as a Lunar dev or as a dev at Meteor client and various other projects.

For serveral months I’ve been developing my own Minecraft client, with the help of SK1er, the founder of Essential mod.

I’m looking for people who wanna be part of my journey.

our Minecraft client has the purpose as every other client, with the exception to shape it with the help of the communety.

So please let me know under this post if yall have idea s what we should implement.

If you need more info just check my GitHub Bejameja.

Hiya, so every time I try to search for information about enchantment "order" it always refers to the optimal levels and order of anvil operations. That's helpful but it's not what I want to try to find out.

As someone who definitely has some kind of combination of Autism/OCD (not gone for official diagnosis) I really want there to be a set structure to my items once enchanted I.e descending order of highest enchant level (sharpness V above unbreaking III above mending)

For a decent number of items in the game ive managed to achieve something like this, for some reason my brain is even okay and satisfied when ascending order with mending at the end since mending only has 1 level and no roman numeral (I.e unbreaking III then sharpness V below and finally mending)

I've been trying to enchant an axe currently and it is frustrating me that it keeps trying to put unbreaking III between efficiency V and sharpness V. I'm not sure if this is something I can even avoid but it's driving me crazy so much so that I'm currently going around with a pickaxe which has a similar issue thinking every moment that I can't wait to enchant a new one and cast this one into lava.

Tl;dr does anyone know how or what plays a part in the convention of labelling enchanted items? Is there a way to manipulate the results so that the enchantments on an item are listed in a certain order even if it costs more levels to do so?

If I was on PC/Java I imagine this would be so much less of an issue since I could look for a mod for this kind of thing.

Edit: I think LimestoneBuilder might have the correct information regarding my issue... in which case its a shame there is no solution to changing the order of enchantment labels.

What is the recommended width of a diagonal ice boat road, as to not bump into the edges? I am building one which is 5 diagonal ice blocks wide and practicing I am bumping much less into the walls than before, but I am not sure if it's possible to never bump the edges unfortunately, at least it's very hard. I think 7 would be much easier to prevent this problem, but would require a lot of changes to my nether highway.

Why is Worm not banned? Can any mod give us a reason? He spams the subreddit, spreads misinformation about the game, defames people with allegations that they have threatened his life, put him in jail, caused his wife to have a miscarriage (all with NO EVIDENCE), says that he is in the process of suing people for pointing out his misinformation, claims that people (such as myself) are alts with no evidence, ignores all the work others have done in the past and slanders them, and brings nothing positive to this subreddit. Can anyone give 1 good reason why this community lets him spread his slop in here?

Look at his most recent post as an example (assuming he hasn’t deleted it, but I have the video saved even if he does). There is 0 tech in this post, 0 explanations, 0 technical Minecraft. Just music playing in the background while he uses litematica to delete all his ‘dead’ designs. What purpose does this serve outside of bloating this sub and stoking Worm’s ego and need for attention? Is this what this sub has come to? And this isn’t an isolated incident, half of Worm’s posts are tiny modifications from previous posts that probably took 5 minutes to change. What if everyone started posting videos of every 5 minutes of their design process as individual. separate. posts? And then the other half of the posts are conspiracy theories about some ST mafia who’s supposedly persecuting him for ‘spreading the truth’

Let me ask this: how many people have him blocked? At what point does it become clear where the problem is? Is that how the mods expect members to deal with spammers and conspiracy crackpots? Just block them? Why even have rules then if that’s the intended path? What will new people think?

If Worm has proof of his claims, that people are lying about game mechanics to coalesce power and ad revenue in Storage Tech, that people from this community SWATted him and sent him to jail, that the Storage Tech discord with 6 years of lossless working designs that predate his doesn’t actually have lossless working designs that predate his, that I and others are alt accounts (this is just straight-up impossible because I know who I am lol), then let him show this proof. And if he does not trust us, let him show a trusted mod who can confirm or deny it once and for all. I’m sick and tired of these baseless lies and the neverending spam

Mods, please step in and moderate your community. This is one of your primary purposes: to keep bad actors out. Worm isn’t just annoying, his conspiracies and lies represent a genuine danger to the community. I hope you at least look into this and consider my (and I’m sure others’) concerns. Cheers
