GASDocumentation
This is a documentation and sample project for learning Unreal Engine's Gameplay Ability System (GAS), focused on building networked gameplay abilities that synchronize correctly in a multiplayer environment. The project provides a step-by-step guide to implementing GAS, covering the core concepts of defining gameplay mechanics through a data-driven attribute system that separates ability logic from character state management.
The documentation explores key architectural patterns for multiplayer ability design, including a predicted-action network model that uses client-side prediction and server authority reconciliation to synchronize ability execution across players. It covers a tag-based ability filtering system for controlling activation, cooldowns, and interactions, as well as a gameplay effect stacking system for managing temporary and permanent attribute modifications with duration, magnitude, and priority rules. The project also demonstrates how to orchestrate complex ability sequences through an ability task graph that chains asynchronous tasks like delays and animations into a directed execution graph.
The sample project exposes the gameplay ability system to designers through Unreal Engine's Blueprint visual scripting, enabling rapid iteration without C++ changes, while maintaining server-authoritative replication to ensure gameplay integrity across networked players. The documentation and accompanying sample project serve as a comprehensive learning resource for implementing networked gameplay abilities, attributes, and effects in Unreal Engine.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
