[1.15] Save data to world using WorldSavedData

Recommended Posts

Hi,

I'm looking to save ArrayLists, in the WorldSavedData class. I already have the following:

 
 
0
 Advanced issue found
 
 
Spoiler

package net.kidkoder.allergies.data;

import net.minecraft.nbt.CompoundNBT;
import net.minecraft.world.storage.WorldSavedData;

public class DataPlayerAllergies extends WorldSavedData {
    private boolean dirty;

    public DataPlayerAllergies() {
        super("playerDataAllergies");
    }

    @Override
    public void read(CompoundNBT nbt) {

    }

    @Override
    public CompoundNBT write(CompoundNBT compound) {
        return null;
    }

    @Override
    public boolean isDirty() {
        return dirty;
    }
}

 

How do I save an ArrayList in to the class in a diffrent class, then retrive it when I need it?

 

 

Thanks in advance,

Kid Koder

Wait what? The ArrayList should be in your WorldSavedData class.

Use a ListNBT to store a "list" of Items.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I have a class that has the logic to decide what does into the ArrayList, and I want to save that ArrayList to data in the world, Then, when the World is loaded again, to read the data and use it. I am using WorldSavedData because it seemed like it would work. If you know any other way to do this, please tell me(Please avoid from file stuff such as creating a file for each world).

Put the logic into the WorldSavedData class?

The whole mod is based upon the logic and requires the logic to be in that class.

Why? It's your code you can manipulate it any way you want.

But, I have thought to create a "config" file for each world, would that work/how would I do that?

You can't do that using the forge config system.

Can't you? I believe the SERVER config type will do exactly what is desired, unless the javadocs are misleading me.

 

I'm eager to learn and am prone to mistakes. Don't hesitate to tell me how I can improve.

I mean't create a new "config file" in the world folder, then can be read back.

Honestly it might, but I'm not sure that's something worth testing. Maybe the OP can enlighten us when/if they try it.

Good point, it might be easier to go with the WorldSavedData, especially since that was what OP wanted in the first place.

It's at least still valuable to learn about Forge's config system in general I guess.
