🎮 UltimateHealthDisplay - Complete Plugin Description

📋 **Overview**

**UltimateHealthDisplay** is a premium-quality, highly optimized health display plugin for Minecraft Paper servers (1.21-1.21.11). It elegantly shows the health of any entity (mob or player) you're looking at directly in your action bar, featuring multiple beautiful display styles, extensive plugin compatibility, and performance-first design.

Unlike basic health display plugins, UltimateHealthDisplay seamlessly integrates with popular custom mob plugins (MythicMobs, LevelledMobs), respects region protection (WorldGuard), and intelligently avoids conflicts with other action bar plugins.

❓ **Frequently Asked Questions**

**Q: Does this work with modded entities?**
**A:** Yes! It works with any entity that extends `LivingEntity`, including modded mobs.

**Q: Can I disable it for specific players?**

**Q: Does it conflict with boss bars?**
**A:** No, boss bars and action bars are separate systems.

**Q: Can I use multiple styles at once?**
**A:** One global style at a time, but you can quickly switch with `/uhd reload`.

**Q: Does it work with 1.20.x?**
**A:** Designed for 1.21+, but may work on 1.20.6 with minor issues.

**Q: How do I create my own style?**
**A:** Copy any existing style in `config.yml`, rename it, modify the icons/message, set `current-style` to your new name.

🐛 **Troubleshooting**

**Health not showing:**
1. Check you have `uhd.use` permission
2. Verify `show-mob-health`/`show-player-health` are `true`
3. Ensure you're not in a blacklisted WorldGuard region
4. Check console for errors

**Wrong health values:**
1. Make sure custom mob plugins are installed (MythicMobs, etc.)
2. Verify plugin hooks initialized (check console on startup)
3. Report the specific entity type on GitHub issues

**Flickering display:**
1. Set `override-action-bar: false` in config
2. Disable conflicting action bar plugins
3. Increase `update-interval-ticks` to reduce update frequency

**Performance issues:**
1. Increase `update-interval-ticks` to 15-20
2. Reduce `max-raytrace-distance` to 30-40
3. Increase `camera-movement-threshold` to 0.05-0.1
