SetControlRotation doesn't work for some reason with Unreal engine

My code:

APlayerController* controller = UGameplayStatics::GetPlayerController(this->GetWorld(), 0);
FRotator Rotation = Controller->GetControlRotation();
Controller->SetControlRotation(Rotation.Pitch + amount*5, Rotation.Yaw, Rotation.Roll);

The error I get:

error C2660, function doesnt accept 3 arguments

What is the reason for that ?

>Solution :

SetControlRotation requires 1 argument of type FRotator, not 3 separate ones for the rotation components (pitch, yaw, roll).

This is the meaning of the error you get (error C2660, function doesnt accept 3 arguments).

You can fix it by constructing a FRotator object from the 3 components, like this:

Controller->SetControlRotation(
//--------------------vvvvvvvv--------------------------
                      FRotator(Rotation.Pitch + amount*5, 
                               Rotation.Yaw, 
                               Rotation.Roll));

Note that although FRotator is composed of the 3 components, it is not the same (from the C++ point of view) as the 3 components given separatly.
