[SOLVED] [1.7.10] Saving NBT to World?

[deadrecon98]

Is there any possible way to save data to the world? I understand the basics of how it works but I can't figure out how to save it to the world. Going the rout of world.getWorldInfo().getNBTTagCompound() does not actually save it to the disc. Any help is much appreciated!

This should be the right method in the WorldInfo class for ou to use...

      /**
     * Allow access to additional mod specific world based properties
     * Used by FML to store mod list associated with a world, and maybe an id map
     * Used by Forge to store the dimensions available to a world
     * @param additionalProperties
     */
    public void setAdditionalProperties(Map<String,NBTBase> additionalProperties)

 

Edit: There is also a getAdditionalProperties method...

WorldSavedData is what you're looking for, I believe.

WorldSavedData is what you're looking for, I believe.

 

Could you give me some advice as to how this would be implemented? I have seen a tutorial using this but he wasn't using it in a static context which is what I need.

That wouldn't help me as it is uses a map.

Nevermind my last post('s). I have figured it out after a few hours of looking at the javadocs . Here is the src for anyone who is having issues!

 

World Data.java

package package;

import java.util.Iterator;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.village.Village;
import net.minecraft.world.World;
import net.minecraft.world.WorldSavedData;
import net.minecraft.world.storage.MapStorage;

public class WorldData extends WorldSavedData {

   final static String key = MODID;
   
   public static WorldData forWorld(World world) {
      MapStorage storage = world.perWorldStorage;
      WorldData result = (WorldData)storage.loadData(WorldData.class, key);
      if (result == null) {
         result = new WorldData(key);
         storage.setData(key, result);
      }
      return result;
   }
   
   private NBTTagCompound data = new NBTTagCompound();

   public WorldData(String tagName) {
       super(tagName);
   }

   @Override
   public void readFromNBT(NBTTagCompound compound) {
  	 data = compound.getCompoundTag(key);
   }

   @Override
   public void writeToNBT(NBTTagCompound compound) {
       compound.setTag(key, data);
   }

   public NBTTagCompound getData() {
       return data;
   }
}

 

How to invoke the NBTTagCompound

WorldData data = WorldData.forWorld(player.worldObj);
	NBTTagCompound tag = data.getData();
	tag.setString("5", "3");
	data.markDirty(); //Save the data to the disc. NEEDED TO WORK!
