About Bossbar
From ModrinthCreate health bars for bosses or entities: easy, performance-friendly, feature-rich.
Bossbar
Enhancing Minecraft's bossbar functionality by properly extending it to entities. No more complicated command block setup, lag-inducing detection logic, and cheap attempts at recreating the real deal. This is the real deal now.
✅ Features
- Entity bossbars take the name, health and max health of its entity.
- Range can be specified for entity bossbars, meaning it's only visible to local players.
- Default bossbars can be configured (see Configuration)
- Thicken fog & darken skies with the extended functionality given to entity bossbars.
- Server-side, meaning clients don't need to download it to connect.
- Easy to use with the ``
/bossbar`` command, swap out a bossbar id with a target selector, and done! - Optimized to a lagless extend, compared to Minecraft's bulky command code.
⚙️ Configuration
Configuration can be found in ``config\bossbar.json``.
