TrapGuard is a client-side Fabric mod for Minecraft 1.21.11 that monitors saved redstone builds and traps for unwanted changes using block-state snapshots... This mod is mostly meant for Private SMPs
Monitoring Modes
- Structural Mode: Ignores transient states such as redstone power while still detecting meaningful structural and configuration changes.
- Exact Mode: Compares the complete saved block state for stricter, more precise monitoring.
Area Selection & Organization
- Select monitoring areas using a configurable selection tool.
- Add individual blocks outside the main selection.
- Organize saved traps into folders.
- Enable or disable monitoring for individual traps (or all of them).
- Display monitored areas using overlays.
Change Detection & Alerts
When a monitored area changes, TrapGuard provides:
- A movable HUD alert.
- Visual highlighting of detected differences.
- Configurable per-trap alert cooldowns.
- A Difference Viewer showing what changed + the coords of it
Exporting
Saved monitoring areas can be exported as .schem (sponge v2) files.
Additional Protection
- TrapGuard accounts for unloaded chunks when checking monitored areas and includes a warning about the special behavior of face-to-face Observer clocks when using Exact Mode.
- This makes TrapGuard suitable for monitoring complex redstone systems and traps while avoiding false positives from normal redstone activity.
