Datapack – Overworld / Nether Coordinate Conversion

This Minecraft datapack allows players to display the equivalent coordinates between the Overworld and the Nether, following the official Minecraft conversion rule:

• Overworld → Nether: divide by 8
• Nether → Overworld: multiply by 8

All calculations are handled using scoreboards, ensuring reliability and full compatibility with vanilla Minecraft mechanics.

Features

• Displays converted player coordinates

• Two separate functions:

• nether.mcfunction → Overworld coordinates ÷ 8

• overworld.mcfunction → Nether coordinates × 8

• Preserved precision using a scaling factor

• Works in singleplayer and multiplayer

• No mods required

Installation

1. Download or clone this repository
2. Copy the day_counter folder into: .minecraft/saves/<your_world>/datapacks/
3. Launch the world
4. Run the following command if the datapack is not loaded: /reload
