I have some NBT data I want to save to .minecraft/saves/<world>/data/myfile.dat.  How would I do that?  I couldn't find out with google or the forge javadocs.  Do I just open a binary file and write the nbt in binary or does Forge have a function I should call?

 

Thanks,

electrodude

 

EDIT:  Also, how can I make it so this data gets loaded and saved automatically (i.e. by calling my object's readFromNBT and writeToNBT methods) on world load and save/quit?

here is the information that I found useful when I made my implementation of saving to world save folder....

and... my implementation..with load/save stuff

(hint...load/save are handled mostly automatically whenever the world loads/saves, you just need to make sure you keep the data up-to-date)

 

Oh hey...Hi diesieben07     hope you don't mind I used your previous example(s)

Thanks!  I looked at your code and that's exactly what I want!  The only question I have left (that I know of atm) is, how is your tracker told to load data (by making a new AWGameData()) on world load?  When is GameDataTracker.handleWorldLoad(World world) called?

That method is called from my event handler, from the worldLoad event:

 

@ForgeSubscribe
public void onWorldLoad(WorldEvent.Load evt)
  {
  if(evt.world instanceof WorldServer)
    {
    GameDataTracker.instance().handleWorldLoad(evt.world);
    }  
  }
