Mob Radar shows you where nearby mobs are while you can't see them.
Like in shooters: an arc lights up at the edge of your screen, pointing toward the mob. The closer it is, the brighter and thicker the arc gets. The moment the mob comes into view, the arc fades away.
Nothing to squint at in a corner, nothing to take your eyes off the game. The information reaches you through peripheral vision, exactly when something is actually behind you.
Features
- Arcs appear only for mobs you can't see. If a mob is on screen, the radar stays quiet
- Brightness and thickness scale with distance
- Every vanilla mob gets its own colour: creepers light green, endermen purple, skeletons white, the warden bright teal. Bosses get deliberately unnatural colours so you can't mistake them for anything else
- Choose what to track: hostile mobs, players, animals, other living entities — plus per-entity include and exclude lists, which also work for modded mobs
- Arcs fade in and out smoothly instead of flickering
Configuration
Everything lives in config/mobradar.json, created on first launch: radar range, colours, arc thickness and length, margin from the screen edge, opacity, fade speed.
There is a hotkey that reloads the config without restarting the game — edit the file, press the key, see the change immediately.
Hotkeys are unbound by default. Bind them in Options → Controls:
- Mob Radar: toggle — turns the radar off and remembers it in the config
- Mob Radar: reload config — picks up your edits to
mobradar.json
Modded mobs
No mod lists involved. A mob is picked up if the game itself considers it hostile, so mobs from other mods work out of the box — they just get the fallback red colour. Give them their own colour by entity id:
"byEntity": {
"twilightforest:naga": "#5FBF3F"
}
Compatibility
Client-side only. Works on vanilla servers, nothing to install server-side. Requires Fabric API.
