IntruderAlerts

A client-side Fabric mod that notifies you whenever an untrusted player enters your render distance. Stay aware of who's approaching you on any multiplayer server — no server-side installation required.

Features

• Instant alerts — Get notified through three channels at once: a bold chat message, a toast popup, and an Ender Dragon growl sound
• Trust list — Mark players as trusted so they never trigger alerts. Saved by UUID, so name changes won't break it
• Safe zones — Define locations where alerts are suppressed (e.g. spawn areas, trading hubs). Zones are dimension-aware and persist across sessions
• Toggle on/off — Quickly enable or disable the mod without restarting
• Fully client-side — Works on any server. No server-side mod or permissions needed
• Persistent config — Your trust list and zones are saved to JSON files and survive restarts

Commands

All commands use the /intruder prefix:

Command	Description
/intruder trust <player>	Add a player to your trust list (with tab-completion)
/intruder untrust <player>	Remove a player from your trust list
/intruder list	Show all trusted players
/intruder toggle	Enable or disable alerts
/intruder zone add <name>	Create a safe zone at your current location
/intruder zone remove <name>	Delete a safe zone
/intruder zone list	Show all safe zones

How It Works

The mod scans nearby players once per second. When an untrusted player first appears within your render distance, you'll receive:

1. A chat message: [IntruderAlerts] PlayerName entered your render distance!
2. A toast notification in the top-right corner
3. An Ender Dragon growl sound effect

You'll only be alerted once per player — they won't trigger repeated alerts until they leave and re-enter your range. If you're inside a safe zone, all alerts are paused.
