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 ?

The problem:

SetControlRotation API 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 in one of the following ways:

1. Add a FRotator variable created from the 3 components and use it with the API:

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

or:

2. Construct a FRotator object from the 3 components directly in the API call, 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.
