ReachHUD

ReachHUD is a tiny client-side overlay that reads the two attributes that actually control how far you can reach — player.block_interaction_range and player.entity_interaction_range — and prints them, live, in the corner of your screen.

What it does

• Two small lines in the bottom-right of the HUD:
• Block: 4.5m — how far you can break or place blocks.
• Entity: 3.0m — how far you can hit mobs and players.
• Each line shows the delta vs. the vanilla survival baseline in parentheses, e.g. Block: 5.0m (+0.5) in creative, or Block: 8.5m (+4.0) if you have an attribute modifier from gear/effects.
• Colour-coded: green when you have a bonus, red when reduced, white when standard.
• Numbers update every frame, so anything that changes your reach is reflected instantly.

Why

• PvP. Crystal-clear feedback on the reach you are actually working with.
• Precise building. Block reach in creative is 5.0 m by default; ReachHUD shows the real number so you don’t overshoot.
• Sanity-check modifiers. Any datapack, server plugin, or mod that touches reach attributes shows up here immediately.

Controls

• K — toggle the HUD on/off (default: ON).

Notes

• Pure client-side. Works on any Fabric server, vanilla-compatible.
• No config file. No HUD when chat/inventory/pause is open, and respects F1.
• Requires Fabric API. One JAR covers 1.21.8, 1.21.9, 1.21.10, and 1.21.11.
