Having error on arena join.
https://pastebin.com/NKstp7fE

Hi,
At the start of a game, players' exp/levels are set to 0 and do not get restored at the end of the game. For a survival server, this creates a huge issue of players losing progress if they play the minigame. Is this a bug or intended design?
(1.20.4, Spigot)
Thanks

Hello, I have a small request.
The idea is to create a break system if players logout off during a game, or e.g. kicks them from the server due to a connection outage.

The pause would last several dozen seconds (To be set in the config). During this period, the game would be temporarily stopped until the player reconnects to the server and the game. If a player disconnects again, the timer would start counting from where he last stopped counting in that match. If the timer runs out, the player will be kicked out of the game and lose. In this way, a temporary lack of internet will not cause problems during the game. This would be important for organizing chess tournaments.

Any chance to add this feature?

Hello - I have server on 1.20.1 version and 1.15.1 MineChess

I have 2 arenas for Chess minigame - and 1 joining sign for each

1 of the signs works properly
but the second one starts being edited (because of the new 1.20+ mechanic to edit placed signs)

I don't know why one sign works proeprly but the other does not...
My arena's names are:
"szachownica1" (works good)
and
"szachownica2" (starts being edited as a sign)

My signs:

example of coding sing:

How it looks when you press the broken sign:

Console warn while clicking the broken sign:
[05:26:52 WARN]: Player tester321 just tried to change non-editable sign

Plugin teleports the player correctly and starts the game correctly but the editing sign annoys the players

Hey, I've been really enjoying your plugin.
Is there a possibility for you to add a player wins leaderboard aswell as support for custom heads support for chess pieces?

Thanks!

Everything worked fine when I set up the arena for the first time. However, after the server restart when I try to join an arena it drops an error, and the chess game won't start. Here are some screenshots.
(I use the 1.18.2 version - Purpur)

This log happened after using the exit door in the inventory, the player was in a 'waiting arena', his items just vanished.

It is possible to put the king in an illegal move while castling.
By chess rules, the king is not allowed to castle if by doing so he is put in danger, however the plugin allows it.

How to replicate:
Set it up so when the king tries to castle, the position he will be after he castles is in sight of an enemy piece. The plugin will allow it, even though this is an illegal move in chess

I noticed when somesone play with this game it spam this

Can you add maven or gradle files to this repo?

I need this, for easiest build plugin from source.

When i join an arena then i can't fly. I know that this is because the arena is in another world than the lobby because when i went to the arena world and then joined the arena i was able to fly. And i have a feeling i know what the problem is: When im right then you are using this code to let the player join your arena:

https://management.azrasoul.de/s/k7QLS5KAgNGfRQf

You first set the player flying and then teleport the player to the arena. Since 1.18 this doesn't work because minecraft disables the flight on any world change.

Because of that i would be really happy if you could change this so the player is first teleported to the arena and then set to flight.
