Custom Boss Template

# Custom Boss Template **A ready-to-use datapack template for creating your own custom boss in Minecraft 1.21+** This is not a finished boss — it’s a **well-commented and easy-to-edit template** that allows you to create **any custom boss** you want, from a simple mob to an epic raid boss. Everything can be customized without deep knowledge of commands. ### Key Features - Boss with **1000 HP** and a beautiful bossbar (easily changeable) - **10 fight phases** that automatically switch based on remaining health - Smart movement AI — the boss always faces the nearest player and slowly walks toward them - Timer system for regular attacks and summoning minions - Particles, sounds, effects on players and the boss itself - Clean victory screen with particles, sound, and custom reward - Works on pure vanilla Minecraft (no mods required) ### What You Can Easily Customize All main files are located in `data/boss/functions/`. Here’s exactly **what you can change and where**: 1. **spawn.mcfunction** — Main file for spawning the boss - Boss display name (`CustomName`) - Entity tag (`muzhlan_boss` — you can change it to your own) - Maximum health (`generic.max_health`) - Attack damage (`generic.attack_damage`) - Knockback resistance - Items in main hand and offhand (with `custom_model_data`) - Starting phase - Spawn title and sound 2. **setup.mcfunction** — Runs once when the world loads - Bossbar title, color, and style 3. **stages.mcfunction** — **The most important file** (controls all phases) - All 10 phases (from 1000 HP down to 100 HP) - When each phase activates based on health - Boss messages in chat (`tellraw`) - Effects on players (slowness, levitation, darkness, etc.) - Effects on the boss (regeneration, strength, speed, etc.) - Minion spawning (zombies, etc.) - Particles - You can freely add, remove, or modify any phase 4. **tick_logic.mcfunction** — Boss attacks - Attack frequency (currently every 3 seconds) - Attack radius - Damage type given to players (`instant_damage`) - Attack sound 5. **victory.mcfunction** — What happens when the boss is defeated - Victory messages - Particles and sounds - Reward given to players (item, name, enchantments, etc.) - Bossbar removal 6. **loop.mcfunction** — Main game loop (recommended not to edit unless you know what you're doing) ### How to Get Started Quickly 1. Download and install the datapack into your world's `datapacks` folder 2. Run `/reload` 3. Use the command `/function boss:spawn` — the boss will appear at your location 4. Open the folder `data/boss/functions` in any text editor (Notepad++, VS Code, etc.) 5. Edit the files according to the instructions above 6. Run `/reload` again and test your boss ### Who Is This Template For? - Adventure map creators - Server owners who want a unique boss - Beginners learning datapacks (everything is well commented) - Experienced creators who want to expand the logic further The datapack is designed so you can change almost everything in **10–15 minutes**, even if you’ve never worked with functions before. **Want to make the boss stronger/weaker, change its appearance, add new phases, or completely different rewards?** Just follow the comments inside the files — everything is clearly explained.
