About this Mod
🧟 Undead Alliance
A Minecraft Mod that lets you turn zombies into loyal companions instead of enemies.
Survive the apocalypse with your own undead allies, each featuring personality, trust, and evolving behavior systems.
⚙️ FEATURES
🤝 Zombie Recruitment
Sneak + right-click on a zombie to attempt recruitment with a base success chance of 40%, modified by personality traits.
🧠 Trust System
Each zombie has a dynamic trust level (0–100):
- 0–19 → Hostile (breaks alliance)
- 20–49 → Suspicious (may retaliate)
- 50–79 → Friendly (follows & protects)
- 80–100 → Loyal (best behavior)
🎭 Personalities
Each zombie has unique behavior traits:
- Loyal – easier recruitment, more forgiving
- Brave – aggressive combat style
- Coward – prioritizes survival
- Protective – stays close to owner
- Lazy – slower movement
- Grumpy – harder to recruit
🪖 Helmet Protection
Helmets prevent zombies from burning in sunlight and slightly increase trust.
🍖 Feeding System
Feed rotten flesh to heal zombies and increase trust (only when needed).
🏕️ Smart AI
Allied zombies will:
- Seek shade or water when burning
- Follow or stay based on commands
- Protect the owner from attackers
- Request food when low on health
💾 Persistence
All alliance data (trust, personality, ownership, states) is saved using NBT storage.
