How I Found my Own Duplication Glitch on 2b2t

The problem with redstone dust is that is the main lag causer, specifically if it has high signal strength

[@fakestory1753]

apparently people just don't know about this , they just try to build lag machines from others peoples design without knowing what they are doing

[@ctreurniet3373]

I thought it's was also laggy cuz of lights updates

[@ouroya]

@@ctreurniet3373 the reason redstone dust causes so much lag is because it has several blockupdates per tick, if the power goes from 15-0 it will have 15 blockupdates instead of just 1, and carpetmod can be used to fix this behavior (copied from my previous comment) however, if it goes from power 15 to power 14, that's just 1 blockupdate

[@EvanOfTheDarkness]

In 1.12 it is. Apparently it sent out updates for each power lever change. So flicking a lever on sends out 15 block updates. It should be better for 1.13+, and there is a fix for it in carpet mod as well. Still, large redstone machines can generate a lot of lag, even in 1.13+.

[@Sharpman76]

@@ouroya Yeah I remember hearing from ilmango about how laggy vanilla redstone is, it's why people making large-scale vanilla farms on non-anarchy servers often avoid redstone dust

The KZbinr ilmango always tries not to use redstone dust in his contraptions, even if it's just a little, because of the lag it can cause You can see this a lot in the contraptions *HE* builds in his skyblock series

[@chrismcgarry2840]

Although on scicraft, a few shulker boxes is "a little" redstone :p

[@menacrise]

Every time the redstone is powered or empowered it causes lighting updates to every block under and adjacent to it, so all those lighting updates cause immense system strain. In addition, when the redstone powers or depowers, it goes through all of the redstone power levels. Powered rails only update once, and their update can be detected by an observer. I believe the redstone lag has been fixed in a later version though, but not 100% sure.

[@returnexitsuccess]

@@menacrise It's actually because when redstone dust goes from being unpowered (level 0) to fully powered (level 15), it actually updates 15 times to go from level 0 to level 1, level 1 to level 2, etc. He'll often use powered rails because these are just one update to turn on and off, or he'll design the circuit to use low power levels so that the redstone dust only moves between level 0 and level 1 for example.

Dupe Glitch Fun Fact: There's a dupe glitch on the New Nintendo 3DS edition of the game where if you have 3 of a stackable item, separate one of them, then hit the quick move button it will change the stack from 3 to a full stack. I've tried it myself and it's definitely one of the easiest dupe glitches in ANY version of Minecraft. The best part is that since that version doesn't get updated anymore it will never be patched, so you can use it all you want

[@MYG]

Watching pay to win servers burn is so satisfying.

[@PEK-97]

Lol I noticed this long time ago on China2B2T, where they were running this exact same plugin, this plugin's code handles the destruction of redstone dusts asynchronously and sometimes it fires before a server tick which causes destroyed redstone to be put back, hence duplicating it.

I think what causes the pag is the lighting updates. Each flick of the lever means the server need to re calculate all of the light around each Redstone dust, which is so fast too much of the server is spent on these calculations making it lag

I think I vaguely recall encountering this dupe a while back on Blockbox, but it was in the creative world and I didn't know the plugin was widely used, so it never occurred to me that the miscount was such a big deal.

[@stefanmirea5305]

A redstone dupe is not that usefull Mumbo Jumbo: say sike right now

[@winksplorer]

no

[@knighToFdemonS]

I think the reason for the duplication is because once too much redstone is detected by the plugin, the block(redstone) breaks and the item gets dropped. but while the server is still doing the redstone-calculation from the first trigger, the already broken block gets another redstone pulse which causes again the block to break and an item to drop (but the server couldnt update the breaking block meanwhile). i wonder if entity drops are have a higher priority then blockupdates in the calculation. if true, if you could trigger enough redstone to drop to limit the blockupdates in the current tick, it would duplicate even more until that chunk is unplayable due to dropped items. you could also try to break other blocks in the same chunk at the same time to duplicate them aswell but it would need multiple instant-breaks in one tick. i dont think thats possible without a mod. and the drop-bug seems to be only plugin related, probably due to its code.

[@dustypapers1850]

yeah no, shut.

[@johnfrian]

Haven't looked at the code, but here is what I think is happening. Fast flipping redstone does the following: 1: Trigger "switch redstone on/off-state" 2: Trigger "drop redstone" if the on/off state has been switched too much and too fast My guess is that sometimes the redstone drops while simutaneously switching its on/off state, leading to both happening at the same time. I.e. a synchronization problem either within the code itself or as a result of variying delay between the client-server communication.

People who watch Ilmango know that pistons, observers and rails combined are a good replacement for redstone dust to REDUCE lag. The main reason why redstone dust is so laggy is because if you depower it from a 15 it actually goes from 15 to 14, then to 13, then to 12, then to 11, and so on. Of course all of this happens in the same gametick but all of these stages get calculated. If you now have a lot of signal strength 15 redstone dust depowering and powering quickly you get a lot of lag. And yes, there are 1-game-tick-clocks in the game.
