How to control movement while on jetpack in air?

[Mxypltk1]

I tried it this way, but it doesnt seem to work either

void AJuniorProgrammerTestCharacter::Tick(float deltaTime)
{
	if (isSpaceBarDown)
	{
		GetMovementComponent()->Velocity.Z = maxRiseSpeed;
		if (maxRiseSpeed != 0)
		{
			AddMovementInput(GetActorForwardVector(), maxRiseSpeed);
			AddMovementInput(GetActorRightVector(), maxRiseSpeed);
		}
		GetCharacterMovement()->SetMovementMode(MOVE_Falling);
	}
}
