Client-side server world info

[Abattoir]

Hello.

 

I would like to create an 1.16.4 client-side mod which can store per-world info but I don’t know how can I get any unique info about a world in a server?

I only found the dimension but I would like to add multiworld support so I have to distinguish the worlds.

Thanks for your answer.

I don’t find that method.

Can you please explain it more how can I get the server world seed from my client-side mod?

Thanks!

I found that on some servers (like Hypixel) the seed is 0.

What can cause this? Is there any other way to identify the world?

 

Code:

@SubscribeEvent
public static void onPlayerJoin(EntityJoinWorldEvent event) {
    if (Minecraft.getInstance().player == null || event.getEntity() != Minecraft.getInstance().player) {
        return;
    }

    BiomeManager biomeManager = Minecraft.getInstance().player.getEntityWorld().getBiomeManager();
    Long seed = ObfuscationReflectionHelper.getPrivateValue(BiomeManager.class, biomeManager, "field_226833_b_");

    if (seed == null) {
        return;
    }

    System.out.println("SEED: " + seed); // DEBUG
}

I found a mod called Xaero's Minimap which can store waypoints per world.

 

 

Do you know how can it recognise the server worlds or it uses a custom method?

Okay.

And what can I do with singleplayer worlds?

They have any unique thing I can get?
