About this project
What does Tick Sync add?
https://github.com/LogGamja/tick-sync-1.21.5
This mod reduces the delay between server packets and client ticks.
This mod also works in Singleplayer, as the client and server are still separated.
이 모드는 서버로부터 도착한 패킷과 틱의 차이를 최적으로 줄여 딜레이를 개선합니다.
싱글플레이에서도 서버와 클라이언트가 분리되어 있기 때문에 이 모드의 효과가 있습니다.
Principle / 작동원리
The Problem
Minecraft works on 20TPS system, with each tick lasting 50ms.
Until 1.20.2 it worked differently, but from 1.20.3 onward, the client waits until the current tick ends before applying a received packet.
Suppose that a packet arrived at 2ms, the client would have to wait 48ms.
If the packet arrived at 40ms, the client would only need to wait 10ms.
This random delays and lag can disrupt your work, if you like using command blocks or block_display to make something.
This mod simply shifts ticks forward or backward to reduce the delay with packets and minimize waiting time.
This feature does not work all the time, and it only works once when there is a problem with sync.

마인크래프트는 1초에 틱 연산을 20번 밖에 하지 않으며 1틱의 간격은 50ms입니다. 1.20.2까지는 그렇지 않았으나 1.20.3부터 서버로부터 패킷을 받으면 해당 틱이 '끝날 때까지 기다리고' 결과를 적용합니다.
만약 패킷이 2ms 시점에 도착했다면 48ms나 기다려야 결과가 반영됩니다. 반면 40ms시점에 도착했다면 10ms만 기다려도 됩니다. 커맨드나 디스플레이 엔티티를 사용해 작품을 만들 때 이 현상이 당신을 괴롭힐 것입니다.
이 모드는 단순히 틱을 밀거나 당겨 패킷과의 시간 차이를 줄이고, 기다리는 시간을 최소화합니다.
이 기능은 상시 작동하지 않으며 동기화에 문제가 생겼을 때 단 한 번만 작동합니다.
