How can I get the directory of the world save folder to save my custom xxx.dat files? I can't find a variable that holds this information. NEI did it properly.

The important part is :

 

 

  File part1 = MinecraftServer.getServer().getFile("");

  String part2 = MinecraftServer.getServer().getFolderName();     

  String filePart2 = part1+"/saves/"+part2;

  if((MinecraftServer.getServer() instanceof DedicatedServer))

    {

    //override the previous statement if it is run on dedicated server

    filePart2 = part1+"/"+part2;

    }

 

 

Took me a bit to track it all down, but it correctly saves to world-save folder on both integrated and dedicated servers.

 

 

public void onWorldLoad(WorldServer worldServer)
  {   
  this.loadedWorlds++;
  
  /**
   * load stats file, populate globalTag
   */  
  File part1 = MinecraftServer.getServer().getFile("");
  String part2 = MinecraftServer.getServer().getFolderName();      
  String filePart2 = part1+"/saves/"+part2;
  if((MinecraftServer.getServer() instanceof DedicatedServer))
    {
    filePart2 = part1+"/"+part2;
    }
  
  if(!filePart2.equals(filePath))
    {
    this.filePath = filePart2;
    this.resetAllTrackedData();
    }
  
  File rawFile = new File(filePart2,"catModGlobalStats.dat");
  NBTTagCompound tempTagData = null;
  try
    {
    tempTagData = CompressedStreamTools.read(rawFile);
    }
  catch (IOException e)
    {
    System.out.println("could not load globalStats, no such file, or improper format");
    return;
    }
  if(tempTagData!=null)
    {
    
    if(this.isTagLoaded)
      {
      /**
       * compare timestamps...if the just read one is OLDER than the existing copy....do nothing
       */
      long time = tempTagData.getLong("tS");
      if(!this.compareDates(globalTag.getLong("tS"), time))
        {
        return;
        }
      }   
    
    globalTag = tempTagData;
    PlayerTracker.instance().loadFromNBT(this.getPlayerTrackingData());
    CatapultMod.serverTeamTracker.loadFromNBT(this.getTeamData());
    this.isTagLoaded = true;
    }  
  }

/**
* compare two long dates as timestamps, returns true if the second is newer than the first, false if first
* is newer
* @return
*/
public boolean compareDates(long first, long second)
  {
  Timestamp t1 = new Timestamp(first);
  Timestamp t2 = new Timestamp(second);
  return t2.after(t1);
  }

public String filePath = "";

public void onWorldSave(WorldServer worldServer)
  {  
  /**
   * save system time into tag
   */
  globalTag.setLong("tS", System.currentTimeMillis());
  File part1 = MinecraftServer.getServer().getFile("");
  String part2 = MinecraftServer.getServer().getFolderName();      
  String filePart2 = part1+"/saves/"+part2;
  if((MinecraftServer.getServer() instanceof DedicatedServer))
    {
    filePart2 = part1+"/"+part2;
    }
  File rawFile = new File(filePart2,"catModGlobalStats.dat");  
  try
    {
    this.filePath = filePart2;
    this.updatePlayerTrackingData(PlayerTracker.instance().saveToNBT());  
    this.updateTeamData(CatapultMod.serverTeamTracker.getTagToSaveToNBT());
    CompressedStreamTools.write(globalTag, rawFile);
    }
  catch (IOException e)
    {
    System.out.println("error writing stats to file, wtf");
    return;
    }
