So, here is what I am trying to do: I need to create a custom file using the File class within java. Trouble is, I can't figure out how to get the resource directory of Minecraft. Here is my code:

public static void createJSON() throws IOException {
	Gson json = new GsonBuilder().setPrettyPrinting().create();

	File jsonFile = new File(whatdoIputhere + "WeightLimit.json");

	if(!jsonFile.exists()) {
		jsonFile.createNewFile();
	}else {
		Writer jsonFileWriter = new FileWriter("/assets/utils/WeightLimit.json");

		FMLControlledNamespacedRegistry<Item> itemRegistry = GameData.getItemRegistry();

		for(Item item : itemRegistry.typeSafeIterable()) {
			String name = itemRegistry.getNameForObject(item).toString();

			json.toJson(name, jsonFileWriter);

			//System.out.println(json.toJson(name).toString());
		}

		jsonFileWriter.close();
	}
}

 

Mainly take a look at where I'm trying to create the file (third line in the method). All I need is the resource directory so I can create the file, but also create it on the server if present. Any help would be appreciated!

THere is no resource directory, they are resource packs.

What YOU want is a config.

Which you're passed the directory in one of the FML init events.

I do know where the config directory method is (the preInit). But, I run through the ItemRegistry to add every item of every mod loaded to this json file. In order to do this, I believe I'd have to create it in postInit, or risk missing some of the items.

So? Store the config folder somewhere until you need it later.

My God, I am so sorry for being this idiotic! Thank you Lex.
