RedstoneHud

RedstoneHud is a clean look-at info layer for redstone builders. Point your crosshair at a repeater or comparator and a small readout appears in the top-left of your screen.

Repeater

• Delay: X ticks (Y.Zs) – the configured tick delay (1-4) and its real time in seconds
• Locked – shown when the repeater is currently locked by a side repeater/comparator
• Output: on / off – whether it is passing a signal

Comparator

• Mode: Compare / Subtract – which mode the comparator is in
• Output: on / off – whether it is outputting a signal

Why

Vanilla gives you no way to read a repeater’s delay setting or a comparator’s mode at a glance – you have to break the block or right-click and count the steps, which is slow and easy to get wrong on a tight circuit. RedstoneHud just tells you, the moment you look at it. No more guessing whether that repeater is on 2 or 3 ticks, or whether the comparator is in subtract mode.

Details

• Pure client-side info HUD – reads only vanilla block state (delay, locked, mode, powered). No mixins, no block entities, no gameplay changes.
• Reads properties generically by their stable names, so it stays accurate across versions even as mappings change.
• Toggle the HUD on/off with G.
• Works on Minecraft 1.21.8 – 1.21.11 (Fabric).
