How to set a Controller dead zone Enhanced Input

Development Programming & Scripting C++

I am trying to recreate the strafing movement in Spartan Assault. But I can’t get the character to go back to it’s idle pose when the character is not aiming because my controller right thumbstick does not reset to zero. Basically when I stop pressing on the right thumbstick the character should go back to the idle pose. Just like in spartan assault. My code is below I am using an if else statement. I am new to C++ and UE I have only been doing this for over a year now.

void ATestController::ControllerAim(const FInputActionValue& Value)
{
FVector2D InputValue = Value.Get();

if (InputValue.X != 0.0f)
{
	GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Blue, FString::Printf(TEXT("InputValue: X = %f"), InputValue.X));
	TestCharacter->bIsAiming = true;
	GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Green, FString::Printf(TEXT("bIsAiming: %d"), TestCharacter->bIsAiming));
	AddYawInput(InputValue.X);
}
else
{
	GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Blue, FString::Printf(TEXT("InputValue: X = %f"), InputValue.X));
	TestCharacter->bIsAiming = false;
	GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Green, FString::Printf(TEXT("bIsAiming: %s"), TestCharacter->bIsAiming ? *FString("True") : *FString("False")));
}

}

According to the on screen debug message it is not resetting. I my animation blueprint I have the character going from Idle to strafe if IsAiming is true and from strafe to Idle if IsAiming is false.

Here is my SetupInputComponent

void ATestController::SetupInputComponent()
{
Super::SetupInputComponent();

UEnhancedInputComponent* EnhancedInputComponent = Cast<UEnhancedInputComponent>(InputComponent);
if(EnhancedInputComponent)
{
	UEnhancedInputLocalPlayerSubsystem* EnhancedSubsystem = ULocalPlayer::GetSubsystem<UEnhancedInputLocalPlayerSubsystem>(GetLocalPlayer());
	if(EnhancedSubsystem)
	{
		EnhancedSubsystem->AddMappingContext(IC_Character, 0);
	}
	EnhancedInputComponent->BindAction(MoveAction, ETriggerEvent::Triggered, this, &ATestController::Move);
	EnhancedInputComponent->BindAction(ControllerAimAction, ETriggerEvent::Triggered, this, &ATestController::ControllerAim);
}

}

here is a clip

Any help would be appreciated.

You may need to also create a binding for ETriggerEvent::Completed where you return to the idle state. See Enhanced Input Thumbstick doesn't give data back to 0 for the Blueprint variant.

Set a Dead Zone modifier in the Input Mapping context:

Thank you I appreciate it. It wasn’t the dead zone it was my programming. I messed up on an if statement I am still learning how to debug in Rider. Embarrassing!!!
