World Between-server Time Synchronization

DrX2345 · Jan 11, 2018

Sure, why not? It's not a big issue, but could easily be added assuming they can literally just copy and paste your code (maybe an edited version idk). It wouldn't change much either way.

I think it isn't a good idea.
I don't care of what time is it in the other worlds it's useless and it will make wynncraft more laggy for the europeans

Why would it be so? I'm also european, and i see no issue with that. This plugin is not going to affect how minecraft time works. The only thing it will affect is how the time is chosen. Usually, the time is different between words, but using this plugin, we will generate the server time based on the real life time. We won't make it so 3 pm in real-life is 3pm in mc. So you won't see a minecraft day taking a real-life day.

Yes but ur thing is U S E L E S S the time is differebt between worlds yes its normal and nobody cares

It's something minor, and not everybody cares, but it's just a small feature that builds up the satisfaction

The_Pl4nte · Jan 12, 2018

yes but for some quests we need to be at day/night do you want to break the gameplay?

how do you know if people want it? ad its something minor so nobody cares

Why would it break those quests? It simply calculates what time it should be based on the real time. It doesn't eliminate the day and night cycle, and neither does it change it. The only thing it will change is when is it night and when is it day. Day & Night size remains the same.

The time between the game servers is currently not synchronized, which leads to people switching servers in order to quickly get soul points back. Not only is this a way to abuse the system, but is also cosmetically unpleasing.
This issue can simply be fixed by synchronizing servers on the restart. The way I thought of synchronizing the server should have a minimal impact on performance, as it is only issued when necessary.

What I thought was actually using the actual in-real-life time to do it. This way, we get a very well synchronized server, with a variation that doesn't exceed a few in-game seconds.

1. Using UMT (Universal Time) as a common ground between all servers
We first need to find something that is already synchronized between the wynncraft servers. The simplest thing is the real-life time, which is already syncronized around millions of devices.

The following is a java method that gives us the current time and date in milliseconds.
Code:
System.currentTimeMillis()
2. Transform the real-life time to Minecraft time.
The first thing we need to do is to examine how the time works in Minecraft. The following observations were simply done by using /time set:

The start of the day is at 0

The end of the day is at 24000.

According to the Minecraft wiki, a Minecraft day takes 20 minutes, which means 1200 seconds. Dividing 24000 to 1200 equals 20. This many ticks pass in a second. This means that a tick passes every 50 milliseconds.

This means that in order to get the Minecraft time synchronized, we need to get the remainder when dividing by 1200000 (1 minecraft day in milliseconds). It will loop back each time a day completes. Now we simply divide it by 50 and so we get the exact tick we need to set time to.

3. Implementation
Implementing it is quite simple and efficient. Simply set the time to this value every time you restart the server, and optionally every 10 minutes.

This is the code that I used to test my algorithm:
Code:
package me.stefandeleanu.time;
import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;

public final class main extends JavaPlugin {
    @Override
    public void onEnable() {
        System.out.println("Syncronising Time!");
        long timemc = System.currentTimeMillis()%1200000/50;
        Bukkit.getWorlds().get(0).setTime(timemc);
   
    }
 
    @Override
    public void onDisable() {
    }
 
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (cmd.getName().equalsIgnoreCase("timesync")) {
            long timemc = System.currentTimeMillis()%1200000/50;
            Bukkit.getWorlds().get(0).setTime(timemc);
            sender.sendMessage("Servers were properly syncronised. " + String.valueOf(timemc));
       
            return true;
        }
        return false;
    }
}

What better way to prove the idea than to show it in action?

5.FAQ

No, it won't. The code i just posted is a very simple code that does simple math that even you can do. It will only run on restart, or once 5 minutes, wich is not going to lag the server. You can compare the performance drop to 2 more mobs (not bosses) added in the game. Allmost 0 performance inpact.

Definetly not. The server will only syncronise the time when the server starts. It will keep syncronised with the game time from then on. It could also be made so the command is ran every 10 minutes or so, wich would be even better.

The only case quests would bug out is in case there are quests that change the time of the day globally (you can also change it per player, by sending a fake packet to the player telling him the time is different. If there is a quest that changes that, this is the way it probabbly does it, in order not to disturb other players). If there was that kind of a quest, you would probabbly see the server changing time every 5 minutes or so, wich is not true.

What we do here is use a very simple math problem to transform the real-life GMT (Greenwich time) into minecraft time. Because GMT is shared between all servers, it means the minecraft time will also be shared.

I have worked at several minecraft servers, helping with system administration and optimisation. I still work at a 2000 player server, where i still improve on my knowledge

Waiting up to 10 minutes for an in-game day cycle to pass isn't game-breaking. If it is, you've got bigger issues man.

And while it is minor, it would be a nice touch overall. The lack of synchronization in time are really annoying to be honest.

So, I do support, but I don't consider fixing this issue a priority at the moment.

The_Pl4nte · Jan 14, 2018

And if you can't wait 10 min?
This idea still useless for me and if i said than it will break THE GAMEPLAY not the quests (you need to learn how to read) its for this reason

It doesn't change anything on the game aspect. If it were implemented, you wouldn't even notice. The day will still be 20 minutes (vanilla), it would still pass naturally, and everything would go smooth. The only change is that it would be syncronised between servers.

To be fair, if it was implemented, you wouldn't even notice. The transition would be too smooth to cause any alarms in your brain. Nothing would be off.

To recap, this is not going to change how the game works, or how the day & night cycle works. The only thing it does is it syncronises real time with the game time, without making 3:00 ingame be 3:00 realtime. What it does is simply dividing the day in 72 pieces, each having 20 minutes (exactly as ingame). Then it does some calculations to set the day proper.

Very simple & effective.

No, this really only serves to make the game harder to play under time constraints when paired with other features of the game.

Good idea though.

Should this idea be implemented?

Yes. I think this idea is beneficial to the server

No. I think this idea is not beneficial to the server
