[1.16.4] Multiple worlds

[Forix]

Hi,

There is a way to create multiple worlds from a dimension? Like when a player connect to server, i have to create a new world from my custom dimension. What is common within these worlds is the dimension which is the same. I actually have my custom dimension with the new json system

I would say don't do that and just register multiple dimensions. Each 'world' is a dimension, so having multiple 'world' with the same dimension qualifier will make it problematic to handle when saving or loading data. However, you can have two JSONs holding the same information under different dimension names.

Ok so, it's possible to dynamically register new dimensions by creating new json dimension file while the server is running?

You cannot dynamically register new dimension within JSON. I think I'm going to need a clearer goal of the task at hand. What are you trying to accomplish on the user end?

i'm actually creating a skyblock mod. the user have to type in the tchat a command to create his island. Each player have is own island, and the thing what i want to do is that each island is in his own dimension

Ah ok. Well, that would be quite complicated. You would need to create a new key for every dimension you create and store them somewhere for easy access. You would also need to construct the ServerWorld, add a world border listener, update the world cache, and send a packet to the player with the required information. This also requires ejecting players from broken worlds or proper teleportation when needed. There are about a hundred other checks that are also necessary. Although, a question I might ask is that why make this a mod? This seems like more a server plugin.

i'm doing this mod for a modded minecraft server. I know that there is things which can support both mods and plugin like magma, but we want to use only mods without plugins.

You know in 1.15 it was so much easier with the DimensionManager class

Well, yes. Now there's a bunch of new caveats. If you really want to attempt this, a similar mod named Hyperbox by Commoble accomplished this. That's probably the best I can do as the process of actually handling is quite complicated and problematic at times.

Thanks you i'm going to check this
