G.A.S. Handlers

Accessing the Ability System Component

Input Handlers related to the Gameplay Ability System can retrieve the owner's Ability System Component from the Input Manager, which is a valid implementation of AbilitySystemInterface.

void UInputHandler_SampleActivation::HandleTriggeredEvent_Implementation(UNinjaInputManagerComponent* Manager, const FInputActionValue& Value, const UInputAction* InputAction, float ElapsedTime) const { UAbilitySystemComponent* ASC = Manager->GetAbilitySystemComponent(); ASC->TryActivateAbilitiesByTag(AbilityTags, true); }

Activate Abilities

You can activate and interrupt Gameplay Abilities using any methods currently supported by the Gameplay Ability System: Class, Ability Tags and Input IDs, each one with its respective Input Handler. However, all these Input Handlers operate in the same way.

• By default, they react to the Triggered event, usually from a Pressed Input Trigger. That Activates the ability.

• If set to Toggle, on a second successful Pressed event, the Input Handler will check if an Ability is active and, if so, cancel it. -Alternatively, adding a Released Input Trigger also will cancel the ability.

Certain Event Triggers like Tap and Double Tap need a special check to determine if the actuation truly happened.

For that purpose, the NinjaInputAbilityActivationCheck, which handles these specific cases. You can extend this class to handle other specific scenarios.

These Input Handlers can also send a Gameplay Event to an ability that already has been activated. This is useful to handle scenarios such as a combo, as implemented by the Combat System.

This option is enabled by the SendEventIfActive property. If enabled, the following properties will become available.

The Event Payload will be configured like the one send from the Send Gameplay Event Input Handler.

Cancel Abilities
