MJCoordinates

A lightweight, accurate actionbar coordinate display datapack for Minecraft.

---

📖 Overview

MJCoordinates is a clean, performance-friendly Minecraft datapack that displays your real-time X, Y, Z coordinates, the current world day count, and your cardinal facing direction directly on the action bar.

Unlike basic data get setups, MJCoordinates includes smart negative coordinate rounding corrections so your actionbar coordinates perfectly match the F3 debug screen across all dimensions.

✨ Features

• 📍 Real-time Actionbar HUD: Shows X, Y, Z coordinates, world day count, and facing direction without cluttering your screen.
• 🛠️ Negative Coordinate Truncation Fix: Corrects the standard Java integer truncation bug where negative coordinates are off by +1.
• 🧭 Full 360° Compass: Accurately maps player yaw angles (-180° to 180°) across all 8 cardinal directions (N, NE, E, SE, S, SW, W, NW).
• ⚡ Optimized Performance: Runs efficiently every tick with minimal score calculations and single-tick tag initialization.
• 🔄 Multi-Version Support: Built natively using Datapack Overlays to support Minecraft versions 1.19 through 26.2 in a single file.

🎯 Supported Versions

• Minecraft Java Edition: 1.19 – 26.2
• Note on Incompatibility Warning: When loading on versions higher than 1.19, Minecraft may show a warning saying the pack is "Made for an older/newer version of Minecraft". You can safely ignore this warning—the native overlays system automatically loads the correct syntax and folders for your game version!
