Boss Radar
by nobody174
Boss Radar lets a player craft a radar item that shows nearby strong mobs on a color-coded ring around the crosshair, with each boss's name and distance.
What it does
Players craft a special compass that senses strong mobs lurking nearby. Held in the hand or placed in the hotbar, the radar draws a ring around the crosshair. The ring changes color as a boss gets closer, moving from a calm tint to red as danger rises, so a player can stay alert without checking the map. Each detected boss is labeled with its name and live distance.
The mod detects the vanilla bosses, the Ender Dragon, the Wither and the Warden, as well as other threats listed in its configuration. The aim is to stop a player from being ambushed by a boss that was not known to be close. Installation is required on both the client and the server, so the server and every player need the mod, and it is built for NeoForge 1.21.1 only.
Boss Radar is not open source and is released under All rights reserved. Source code and an issue tracker are public, and the files are published for 1.21.1 only.

Staying alert on multiplayer servers

Who it’s for: Players who want a warning before a strong mob comes close, and server owners who want the same warning for every player on their world.
