So i have a 1.20.4 mod that saves data and loads it using commands. but the problem is that its not saving separately for each world. so i was looking through the docs and stumbled upon (SD) but the docs arent really helpful. heres my script to save data package com.example.coordinatesmod.commands; import com.mojang.brigadier.CommandDispatcher; import com.mojang.brigadier.arguments.StringArgumentType; import net.minecraft.commands.CommandSourceStack; import net.minecraft.commands.Commands; import net.minecraft.network.chat.Component; import net.minecraft.server.level.ServerPlayer; import net.minecraft.server.MinecraftServer; import net.minecraft.world.level.storage.LevelResource; import java.io.*; import java.util.HashMap; import java.util.Map; public class SaveCoordsCommand { private static final Map<String, String> namedCoordinates = new HashMap<>(); private static File saveFile; public static void register(CommandDispatcher<CommandSourceStack> dispatcher) { dispatcher.register(Commands.literal("savecoords") .then(Commands.argument("name", StringArgumentType.string()) .executes(context -> { ServerPlayer player = context.getSource().getPlayerOrException(); String name = StringArgumentType.getString(context, "name"); String coords = String.format("X: %.1f Y: %.1f Z: %.1f", player.getX(), player.getY(), player.getZ()); namedCoordinates.put(name, coords); saveFile = getSaveFile(context.getSource().getServer()); saveCoordinatesToFile(); player.sendSystemMessage(Component.literal("Coordinates saved: " + name + " " + coords)); return 1; })) ); loadCoordinatesFromFile(); } public static Map<String, String> getNamedCoordinates() { return namedCoordinates; } private static void saveCoordinatesToFile() { try (PrintWriter writer = new PrintWriter(new FileWriter(saveFile))) { for (Map.Entry<String, String> entry : namedCoordinates.entrySet()) { writer.println(entry.getKey() + ":" + entry.getValue()); } } catch (IOException e) { e.printStackTrace(); } } private static void loadCoordinatesFromFile() { if (saveFile == null || !saveFile.exists()) { return; } try (BufferedReader reader = new BufferedReader(new FileReader(saveFile))) { String line; while ((line = reader.readLine()) != null) { String[] parts = line.split(":", 2); if (parts.length == 2) { namedCoordinates.put(parts[0], parts[1]); } } } catch (IOException e) { e.printStackTrace(); } } public static void clearCoordinates() { namedCoordinates.clear(); saveCoordinatesToFile(); } private static File getSaveFile(MinecraftServer server) { File worldDirectory = server.getWorldPath(LevelResource.ROOT).toFile(); return new File(worldDirectory, "coordinates.txt"); } }
