Server-side support DH fork 1.21

Official repo got updated download from there: Download

This is a work-in-progress, don't expect it to work correctly! Especially 1.21

"Open to LAN" servers don't work yet, use a dedicated server instead.

Links

Drop the matching jar into mods/ of the server and clients.
On server: open an additional TCP port. The process is same as for opening MC port. Default port is 25049, but you can change it in mod's settings & config.

How to open ports?
- How to open Minecraft port. However, this is not necessary if you don't expose MC server to the internet or use port forwarding tools like ngrok/playit.
My port forwarding tool gave me wrong port/two different IPs!
- Change connect config using these commands:
  - /dhconfig connectIpOverride <given IP>,
  - /dhconfig connectPortOverride <given port>,
- then rejoin the server.
How to check if fork is installed correctly?
- Check for connection status F3 line when on server, in between other DH status lines.
Will players with mainline DH/without the mod at all be able to connect to the server with DH fork?
- Yes, everything will function normally but they won't receive LODs from server.
Does/Will this fork support X (not related to networking/server side)?
- It supports X the same way mainline DH supports it.
How to change server side settings?
- Use /dhconfig (operator only)
How to import pre-generated LODs?
- Put them into world/, in the structure same as of singleplayer world (more info below).

Singleplayer:

Overworld: .minecraft/saves/WORLD_NAME/data/DistantHorizons.sqlite
Nether: .minecraft/saves/WORLD_NAME/DIM-1/data/DistantHorizons.sqlite
End: .minecraft/saves/WORLD_NAME/DIM1/data/DistantHorizons.sqlite
Custom Dimensions: .minecraft/saves/WORLD_NAME/DIMENSION_FOLDER/data/DistantHorizons.sqlite

Multiplayer:

Dedicated servers

Same as singleplayer, except .minecraft/saves/WORLD_NAME/ should be replaced with server_folder/world/.
