Where can I get the directory of the save file for the current world the player is playing on. I want to save my own custom data file there.

I tried (DimensionManager.getCurrentSaveRootDirectory(), but it is saying, "DimensionManager cannot be resolved". Also, the reason I want to save the data in my own data system is because the current implementation of saving data to the world data would be  a bit complex to use for my mod, so it would be easier for me to use my own data saving system, I harvested it from another game I made, non minecraft related, and all I needed was a directory to save the file to. Sorry if my answer was a bit difficult to understand, its hard to explain and English is not my first language.

Sometimes Eclipse can't find the class. Do

DimensionManager d; 

and it should allow you to import just fine.

Not to forget, the saved game is different on an integrated server than on the dedicated server.

 

I used this in 1.7.10.  It's probably similar in 1.8.

 

In my proxy classes:

 

DedicatedServer::
  /**
   * Obtains the folder that world save backups should be stored in.
   * For Integrated Server, this is the saves folder
   * For Dedicated Server, a new 'backupsaves' folder is created in the same folder that contains the world save directory
   *
   * @return the folder where backup saves should be created
   */
  @Override
  public Path getOrCreateSaveBackupsFolder() throws IOException {
    Path universeFolder = FMLServerHandler.instance().getSavesDirectory().toPath();
    Path backupsFolder = universeFolder.resolve(SpeedyToolsOptions.nameForSavesBackupFolder());
    if (!Files.exists(backupsFolder)) {
      Files.createDirectory(backupsFolder);
    }
    return backupsFolder;
  }

IntegratedServer (ClientProxy)::
  /**
   * Obtains the folder that world save backups should be stored in.
   * For Integrated Server, this is the saves folder
   * For Dedicated Server, a new 'backupsaves' folder is created in the same folder that contains the world save directory
   *
   * @return the folder where backup saves should be created
   */
  @Override
  public Path getOrCreateSaveBackupsFolder() throws IOException {
    return new File(Minecraft.getMinecraft().mcDataDir, "saves").toPath();
  }
