so I've been trying to do some game development as a weekend project for a change.

I'm currently can't get motion controls to work properly.

Now if I understand corectly you would bind motion controls like this:

void ASImpleBallPawn::SetupPlayerInputComponent(class UInputComponent* InputComponent)
	InputComponent->BindVectorAxis("MoveVector", this, &ASImpleBallPawn::MoveVector);
void ASImpleBallPawn::MoveVector(FVector motionVector)
	GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, FString::Printf(TEXT("x: %f, y: %f, z: %f"), motionVector.X, motionVector.Y, motionVector.Z));  
However the values are always 0

If I bind "Gravity" for example to a regular Input-Axis it does work, but I only get a single Axis....

Any help?
