The Gameplay Ability System is a framework for building attributes, abilities, and interactions that an Actor can own and trigger. The system is designed to be adapted to a wide variety of Gameplay-Driven projects such as Role-Playing Games(RPGs), Action-Adventure games, and Multiplayer Online Battle Arenas games(MOBA).
With the Gameplay Ability System, you can:
-
Use the Ability System Component. The Ability System Component includes all the base functionality that an Actor Component implements.
-
The Ability System Component implements its own Interface to access and interact with the framework of the Gameplay Ability System.
-
Create active or passive Gameplay Abilities, for Actors that coordinate with your project's gameplay mechanics, visual effects,animations, sounds, and other data-driven elements.
-
Use Attributes and Attribute Sets that store, calculate, and modify your gameplay-related values as they interact with the Gameplay Ability System.
-
Change Attributes with Gameplay Effects that provide a method to directly modify attribute values with your project's design. Gameplay Effects contain Gameplay Effect Components that determine how a Gameplay Effect behaves.
-
Ability Tasks(
UAbilityTask) are a specialized form of a Gameplay Task class that work with Gameplay Abilities. Games that use the Gameplay Ability System usually include a variety of custom Ability Tasks which implement their unique gameplay features. They perform asynchronous work during a Gameplay Ability's execution, and have the capability to affect execution flow by calling Delegates in native C++ code or moving through one or more output execution pins like Blueprints.
Using this system, you can create abilities like a single attack, or add more complexity like a spell that triggers many status effects depending on data from the user and the targets.
