How to attach a UCameraComponent to a capsule?

[Kal213]

Hello all. I'm very new to Unreal, but decently familiar with C++, so I've been following the FPS tutorial over in the docs (found here, in particular the step I'm struggling with.)

My compiler is not very happy with the line

FPSCameraComponent->SetupAttachment(GetCapsuleComponent());

saying that it cannot convert a UCapsuleComponent* to a USceneComponent*.

I'm running Unreal 4.23, and I know that this tutorial is out of date, but it's been working so far. Has Unreal changed the way this is handled? How can I attach a camera to a capsule component? Is there a way to convert it into a scene component?

I can't really find anything online to help me, so any help would be appreciated!

The issue is that it doesn't know what a UCapsuleComponent is.

Add this to the CPP file:

#include "Components/CapsuleComponent.h"

That was it, thank you for the help!
