UAbilitySystemComponent

class GameplayAbilities Blueprint Since unknown

Inherits: UObject › UActorComponent › UGameplayTasksComponent › UAbilitySystemComponent

#include "AbilitySystemComponent.h"

Description

The core component of the Gameplay Ability System (GAS). Manages a character's granted abilities, active gameplay effects, and attribute sets. Must be added to any actor that participates in GAS.

Caveats & Gotchas

• GiveAbility and most effect-application functions require server authority. On clients, only call functions marked BlueprintCallable without BlueprintAuthorityOnly.
• The component implements IAbilitySystemInterface on the owning actor — implement that interface to allow other GAS helpers to find it.
• Ability activation is asynchronous on clients using prediction; never assume an ability is active immediately after calling TryActivateAbility on a client.

Example

Add the component in a Character constructor C++

AbilitySystemComponent = CreateDefaultSubobject<UAbilitySystemComponent>(TEXT("AbilitySystemComponent"));
AbilitySystemComponent->SetIsReplicated(true);
AbilitySystemComponent->SetReplicationMode(EGameplayEffectReplicationMode::Minimal);
