AActor::InputComponent

property Engine Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: UPROPERTYDuplicateTransient

Description

The UInputComponent that handles input bindings for this actor when input is enabled. Null until EnableInput() is called, which creates and registers it.

Caveats & Gotchas

• This is null by default and only populated after EnableInput() is called for this actor. Attempting to bind inputs before EnableInput() will crash.
• Marked DuplicateTransient, so it is not copied when the actor is duplicated (e.g. via Duplicate In Editor). Each actor instance must have EnableInput() called independently.

Signature

UPROPERTY(DuplicateTransient)
TObjectPtr<class UInputComponent> InputComponent

Example

Bind an action after enabling input C++

void AMyActor::EnablePlayerInput(APlayerController* PC)
{
    EnableInput(PC);
    // InputComponent is now valid
    InputComponent->BindAction("Interact", IE_Pressed, this, &AMyActor::OnInteract);
}
