I have a class that extends WorldSavedData in my mod. This class saves data to the NBT telling my mod which components of it to load for each specific world.

 

When I create a world initially, the components that need to load will load. Upon restarting the world, but not Minecraft, the components load again. However, upon a Minecraft restart, the components no longer work.

 

The code for my WorldSavedData class is below:

 

package tk.cephlab.ea.internal;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.WorldSavedData;
import tk.cephlab.ea.EALoader;
import tk.cephlab.ea.api.EAPlugin;

public class EAWorldData extends WorldSavedData
{
public EAWorldData() 
{
	super("EAWorldData");
}

@Override
public void readFromNBT(NBTTagCompound nbt) 
{	
	EAPlugin.day = nbt.getInteger("eaDays");

	for(EAPlugin plugin : EALoader.instance().getPluginList())
	{
		if(nbt.getString("loadedPlugin" + EALoader.instance().getPluginList().indexOf(plugin)) == null) continue;

		if(nbt.getString("loadedPlugin" + EALoader.instance().getPluginList().indexOf(plugin)) == plugin.getIdentifier())
		{
			System.out.println("Loaded");
			EALoader.instance().initPlugin(plugin);
		}
	}

	for(EAPlugin plugin : EALoader.instance().loadedPlugins)
	{
		plugin.phase = nbt.getInteger(plugin.getIdentifier() + "_phase");
	}
}

@Override
public void writeToNBT(NBTTagCompound nbt) 
{
	nbt.setInteger("eaDays", EAPlugin.day);

	for(EAPlugin plugin : EALoader.instance().loadedPlugins)
	{
		nbt.setInteger(plugin.getIdentifier() + "_phase", plugin.phase);
		nbt.setString("loadedPlugin" + EALoader.instance().loadedPlugins.indexOf(plugin), plugin.getIdentifier());
	}
}
}

 

Any and all help is appreciated.

Switching to using modId is still not working.

 

package tk.cephlab.ea.internal;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.World;
import net.minecraft.world.WorldSavedData;
import net.minecraft.world.storage.MapStorage;
import tk.cephlab.ea.EALoader;
import tk.cephlab.ea.api.EAPlugin;

public class EAWorldData extends WorldSavedData
{
public EAWorldData(String s)
{
	super(s);
}

public EAWorldData() 
{
	super("EAWorldData");
}

public static EAWorldData forWorld(World world)
{
	MapStorage storage = world.getPerWorldStorage();
	EAWorldData returnable = (EAWorldData)storage.loadData(EAWorldData.class, "EAWorldData");
	if(returnable == null)
	{
		returnable = new EAWorldData();
		storage.setData("EAWorldData", returnable);
	}
	return returnable;
}

@Override
public void readFromNBT(NBTTagCompound nbt) 
{	
	EAPlugin.day = nbt.getInteger("eaDays");
	System.out.println("READ");

	for(EAPluginContainer plugin : EALoader.instance().getPluginList())
	{
		if(nbt.getString("loadedPlugin" + EALoader.instance().getPluginList().indexOf(plugin)) == null) continue;

		if(nbt.getString("loadedPlugin" + plugin.container.getModId()) == plugin.container.getModId())
		{
			System.out.println("Loaded");
			EALoader.instance().initPlugin(plugin);
		}
	}

	for(EAPluginContainer plugin : EALoader.instance().loadedPlugins)
	{
		plugin.plugin.phase = nbt.getInteger(plugin.plugin.getIdentifier() + "_phase");
	}
}

@Override
public void writeToNBT(NBTTagCompound nbt) 
{
	nbt.setInteger("eaDays", EAPlugin.day);
	System.out.println("WRITE");

	for(EAPluginContainer plugin : EALoader.instance().loadedPlugins)
	{
		nbt.setInteger(plugin.plugin.getIdentifier() + "_phase", plugin.plugin.phase);
		nbt.setString("loadedPlugin" + plugin.container.getModId(), plugin.container.getModId());
	}
}
}

if(nbt.getString("loadedPlugin" + EALoader.instance().getPluginList().indexOf(plugin)) == null) continue;

You need to use the modID here too.
