[1.15.2] get World variable from save

[foreverstranded]

Hi, is there any way to create world variable from save file?

Something like this:

World currentWorld = new World("pathToDirectory");

[foreverstranded]

I wanted to create World variable with already set parametres like WorldInfo, Seed. I need this to use create ChunkGeneratorOverworld at my client while I'm on server.

What are you trying to achieve? Are you trying to load the world?

Why?

[foreverstranded]

I figured out how to get current loaded world via Minecraft class but it still probably won't work because, I suppose, you can't get full WorldInfo from server.

to generate chunk at my client and then compare it with one that is on the server.

for example too see what blocks got changed from natural generation.

That won't work on servers unless you are OP, because only OPs can get the world seed.

I understand, but if I know the seed and know that generation settings are default can I somehow create World object?

You'd have to create a ServerWorld, because client worlds don't generate anything. And those rely on a MinecraftServer instance that is started... This is a big can of worms you are opening here.

I see... But do you know in which class Minecraft creates MinecraftServer? Can't find

EDIT: I realized it is in New instance creation

Nope, I was wrong. There is no New instace creation for MinecraftServer.java. Only instanceof in Snooper class. Is this what I need to create instance of MinecraftServer?

[foreverstranded]

or I better ask: how can I create instance of MinecraftServer?

[foreverstranded]

or is there any open projects that involves MinecraftServer?

You can look at Minecraft#launchIntegratedServer.

You will most likely have to adjust it considerably, as that method shuts down everything else and prepares to join a single player game.

Thanks!

Yep, this will be tough

You should really just make the mod server side and send whatever information you need from there to the client.
