Mobbility [Addon: Spell Engine]

by UtherHel

Mobbility, an addon for Spell Engine, lets mobs cast spells with animations and cooldowns the way players do.

FabricForgeClient and serverMIT License1.20.1

What it does

Once installed, mobs that carry Spell Engine items gain casting abilities when they spawn, and their combat behavior is chosen from the item tags they hold. An item tagged as a wizard tool switches a mob to a spell-based combat AI that keeps its distance and strafes, while mobs without such items fight with their basic AI.

Class presets assign pre-configured loadouts at spawn. Custom item tags from other mods can be added to the check, so mobs with those items can also be detected.

Mobbility requires Architectury API, Sinytra Connector and Spell Engine. It is published for Fabric and Forge, with files for 1.20.1 only, and runs on client and server. The code is licensed under the MIT License, but the project is not open source.

Key features

  1. Player-like spell casting

    Mobs cast spells with the same animations and cooldowns that Spell Engine gives players.

  2. Automatic ability detection

    Mobs holding Spell Engine items gain casting abilities at spawn without manual setup.

  3. Tag-based AI selection

    Item tags decide whether a mob uses the wizard AI, which keeps distance and strafes, or the basic combat AI.

  4. Class presets

    Pre-configured loadouts such as Archer, Rogue, Tundra Hunter and Plaguebringer spawn automatically.

  5. Custom tag support

    Item tags from other mods can be added to the detection check, so their staffs and spellbooks also trigger wizard behavior.

Questions

Yes. Spell Engine is a required dependency, and Architectury API and Sinytra Connector are required as well.

Which loaders does Mobbility support?

Mobbility is published for Fabric and Forge. Both Fabric and Forge files target 1.20.1.

Does Mobbility have to be installed on both sides?

A server running it needs every connecting player to have it too.
