Easy Ability Set System for Gameplay Ability System

Quick Links

FabFab

The Easy Ability Set System is a Lyra-inspired, lightweight plugin that extends Unreal Engine’s Gameplay Ability System (GAS). It lets you easily define, grant, clear, and manage groups of abilities at runtime—no more assigning abilities one by one!

New to GAS?
The Gameplay Ability System is powerful but advanced. If you’re new, check out this GAS Tutorial.

With this plugin, you can bundle abilities into Ability Sets and apply them to any actor using the Ability System Set Manager—all with a designer-friendly workflow.

🔹 What Does This Plugin Provide?​

  • Ability Sets:
    Create groups of abilities and grant or remove them at runtime using the Ability System Set Manager component.

  • Input Bindings:
    Use Data Assets to manage input bindings for both players and NPCs. Add or remove bindings at runtime—no code required!

  • Data-Oriented Design:
    Designers can create modular gameplay by mixing and matching Ability Sets and input mappings for different game modes or features.

  • Networking Support:
    All features work seamlessly in multiplayer.
