Gameplay Ability System

Set up the Gameplay Ability System: abilities, effects, cues, attribute sets and the ability component.

What it’s for

This area creates and connects the assets behind Unreal’s Gameplay Ability System. Your assistant builds GameplayAbility, GameplayEffect, GameplayCue notify, AttributeSet and execution calculation Blueprints. Then it sets the details that make them work together: modifiers, costs, cooldowns, duration and stacking, granted tags, targeting, instancing and replication.

Use it when you are setting up GAS or adjusting it. Ask for an attribute set and its attributes, a damage or buff effect, or an ability granted to an actor’s AbilitySystemComponent. You describe the ability or effect, and your assistant creates the assets and connects them, so you skip a dozen editor panels.

This area covers the GAS assets. For the tag list and tag queries, see Gameplay tags. For match rules, movement and replication outside GAS, see Game rules and modes, Characters and movement and Replication and networking.
