[1.15.2] Event for Creating Single Player World

[PulseBeat_02]

Hi, I was looking around for an event which would could be used while the user is creating a single player world. (For example, methods with this event would be called when the user is creating a single player world). Does anyone know a possible event which exists? If there isn't an event, please tell me a way to do this without using the event.

Ah. Thank you for the event. I was thinking of if there was more specific events, such as something like onWorldCreate, onWorldLoad, onExitWorld, something like that.

Ah. I see. Thank you for helping me find what the other events are that I needed to use. That means that if I want to check if a user is creating a fresh world, I would have to make a new class which extends WorldSavedData (which would contain a constructor that would be invoked if the player is creating a new world). Here is my code, (and the method used to determine if a world is newly created is inside the class):
 

import org.kingmammoth.kmcutscenes.KingMammothCutScenes;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.storage.WorldSavedData;
import net.minecraftforge.fml.client.FMLClientHandler;

public class FreshWorldCreation extends WorldSavedData {

	private static final String DATA_NAME = KingMammothCutScenes.MODID + "_CUTSCENEDATA";

	public FreshWorldCreation() {
		super(DATA_NAME);
	}

	@Override
	public void readFromNBT(NBTTagCompound nbt) {

	}

	@Override
	public NBTTagCompound writeToNBT(NBTTagCompound compound) {
		return null;
	}

	public static boolean isFreshlyCreated() {

		FreshWorldCreation instance = (FreshWorldCreation) FMLClientHandler.instance().getWorldClient().getMapStorage()
				.getOrLoadData(FreshWorldCreation.class, DATA_NAME);

		return instance == null ? true : false;

	}

}

 

Is that correct?

No, you cannot use the client world. The client world does not store data at all.

 

Oh yeah, I forgot lol. If I recall properly, I would need to use the MinecraftServer.getServer().worldServers method (Unless it was changed in the recent versions of forge). This would return an array of all loaded Worlds. I would then change the method to a loop which would run through all of the loaded worlds.

That makes way more sense now. I was a bit confused originally because that method return an array of worlds, and I wouldn't know which world that would be currently loading in. Ah. Thank you for your help.
