Unreal Engine –GAS Companion UE293

It includes the necessary initial C++ setup, helpers and additional features to get started on a new project that aims to use Epic’s GAS plugin (used namely in Fortnite and Paragon, and showcased in Action RPG project)

It enables non C++ developers to work with GAS using only Blueprints. Even non BP friendly, c++ required parts of GAS like Gameplay Attributes can be handled with a custom C++ generation Wizard for Attribute Sets.

Similarly, GAS Companion can help existing projects that are considering the use of GAS and accelerate the implementation, or provide guidance.
