MCA Reborn x Vampirism Compat

MCA Reborn x Vampirism Compat is a compatibility addon for Minecraft 1.20.1 Forge that integrates Minecraft Comes Alive Reborn villagers with Vampirism, Werewolves, Vampirism Integrations and Easy Villagers.

The main goal of this mod is simple:
MCA villagers should remain real MCA villagers.

Instead of replacing them with vanilla villagers, converted villagers, aggressive villagers or full werewolf/vampire entities, this addon keeps MCA villagers as VillagerEntityMCA while adding faction-aware behavior, curing, combat, trade, social interactions and compatibility rules.

This means villagers can become vampires, hunters or werewolves while keeping their MCA identity, appearance, family data, relationships and social systems intact.

Main Features

• MCA villagers can become vampires without being replaced.
• MCA villagers can become hunter-aligned through hunter village logic or faction state.
• MCA villagers can become werewolf-aligned while keeping their MCA model and identity.
• Vampire and werewolf villagers can be cured.
• Faction-aware trade and social interactions.
• Faction-aware pickup permissions for Easy Villagers.
• MCA command permissions based on faction.
• Special AI respects MCA Follow and Stay commands.
• Prevents unsafe aggressive villager replacement for MCA villagers.
• Special villagers can ignore common monsters and avoid inappropriate panic behavior.
• Balanced and configurable attributes, movement and combat behavior.
• Easy Villagers integration through mca-ev-compat.

Vampire, Hunter and Werewolf Villagers

MCA villagers can become vampire-aligned, hunter-aligned or werewolf-aligned through compatibility-controlled systems.

Each faction adds its own behavior: vampire villagers can use configurable vampire mechanics such as biting valid targets, hunter villagers can use hunter-aligned behavior such as poisonous blood against vampire biters, and werewolf villagers can use werewolf-aligned behavior with partial visual features such as ears and claws.

All three faction types support faction-aware trade, social rules, AI behavior and configuration options. Vampire and werewolf villagers can also be cured back into normal villagers, while hunter alignment can be removed when it is no longer valid.

Curing

Converted MCA vampire and werewolf villagers can be cured using a ritual inspired by vanilla zombie villager curing.

The cure requires:

• Weakness
• Golden Apple
• Vampirism Garlic Injection (vampirism:injection_garlic)

Curing removes the faction state and related visuals without replacing the MCA entity.

Faction-Aware Trade and Social Interactions

Trade and social behavior can change depending on the faction of both the player and the villager.

The mod supports:

• vampire, hunter and werewolf faction logic;
• vampire disguise handling;
• transformed and non-transformed werewolf distinction;
• faction-based trade blocking or price changes;
• social interaction blocking or penalties;
• compatibility with existing discounts such as zombie-cure or reputation discounts.

Easy Villagers Compatibility

Easy Villagers support is handled together with mca-ev-compat.

This mod does not replace the base MCA pickup, restore, NBT preservation or rendering logic from mca-ev-compat. Instead, it adds faction-aware rules around that system.

Implemented Easy Villagers support includes:

• pickup permissions by faction;
• blocking pickup while a villager is being cured;
• read-only stored villager faction detection;
• faction-aware Trader block behavior where stored MCA data can be resolved safely.

Stored Easy Villagers NBT is inspected read-only and is not modified by this mod.

MCA Commands and Faction Permissions

Special villagers respect MCA commands.

The mod also adds faction-based command permissions. By default, special villagers only accept direct MCA commands from compatible or allied factions.

For example:

• vampire players can command vampire villagers;
• hunter players can command hunter villagers;
• werewolf players can command werewolf villagers;
• enemy factions cannot command each other by default;
• vampire disguise does not bypass command permission checks.

Configuration

A Forge common config is generated at:

config/mca_vamp_compat-common.toml

Debug options are disabled by default.

Known Notes

This mod is a compatibility addon that interacts with several complex mods at once. While many systems have been tested, bugs may still happen, especially in large modpacks or unusual edge cases.

Some internal identifiers may still use legacy names for compatibility with existing saved villager data. This is intentional and helps avoid breaking worlds or stored MCA villagers.

Bug Reports and Feedback

Feedback is very welcome.

If you find a bug, please include as much information as possible

Suggestions, balance feedback and compatibility ideas are also welcome. I’ll try to respond as quickly as I can.

Please keep in mind that this mod may still contain bugs, especially because it connects MCA Reborn with several large faction and villager systems.
