AActor::CreateInputComponent

function Engine Blueprint Since 5.1

#include "GameFramework/Actor.h"

Access: public Specifiers: UFUNCTIONBlueprintCallablevirtual

Description

Creates the actor's InputComponent using the provided class. Called internally by EnableInput; override or call directly when you need to use a custom UInputComponent subclass (e.g. UEnhancedInputComponent).

Caveats & Gotchas

• This was added in UE 5.1 alongside the Enhanced Input system. In 5.0 and earlier, input component creation was handled implicitly inside EnableInput without a public override point.
• If you call EnableInput before calling CreateInputComponent with a custom class, the default UInputComponent will be created. Call CreateInputComponent first (or override it) if you need Enhanced Input bindings.

Override to use EnhancedInputComponent C++

// In actor subclass .cpp
void AMyActor::CreateInputComponent(TSubclassOf<UInputComponent> InputComponentToCreate)
{
    Super::CreateInputComponent(UEnhancedInputComponent::StaticClass());
}

// Then bind Enhanced Input actions after EnableInput:
UEnhancedInputComponent* EIC = Cast<UEnhancedInputComponent>(InputComponent);
if (EIC && InteractAction)
{
    EIC->BindAction(InteractAction, ETriggerEvent::Triggered, this, &AMyActor::Interact);
}
