Find noisy redstone clocks before they lag your server
Paper 1.21+ · Auto-detect · Score actions · Staff-friendly
⚠ ALPHA — early build. Features can change, please report bugs on Discord.
✦ Overview
PulseRadar watches live redstone activity, spots circuits that pulse way too hard, and helps you shut them down before TPS tanks.
Designed for survival / skyblock / creative servers where players love clocks — and staff need a clean way to find them.
- Live auto-detect — chat / action-bar alerts when a hotspot gets noisy
- Score system — warnings stack into DISABLE, then BREAK (configurable)
- Manual scans — /pr 30 style timed searches with clickable list & teleport
- BREAK markers — remove the circuit piece, optional item drop, floating hologram players can dismiss
- Config migrations — updates add missing keys automatically (no more “delete your config”)
- Update checker — notifies on server start, on interval, and when ops / staff join
▲ Noisy pulse alert
✦ Features
Toggle exactly what counts: wire, repeaters, comparators, observers, pistons, sculk, hoppers, and more.
Ignore worlds, blacklist materials (e.g. redstone ore), merge nearby pulses into one hotspot.
Score & actions
Score rises mainly per alert (~1–3), not every redstone tick — so values stay readable.
Then apply graduated responses:
- NONE — observe only
- DISABLE — briefly interrupt the block (soft)
- BREAK — remove the piece; place AIR / water / sign / … ; optional hologram + item drop
▲ DISABLE — soft interrupt
▲ BREAK — block removed
BREAK holograms auto-despawn, show “Click to remove”, and can be cleared by normal players nearby (/pr clearholo).
▲ BREAK hologram + highlight
