Unusual Errors

Development Programming & Scripting C++

I’m new to the Unreal 5 engine C++ API.
I’m receiving an unusual syntax error where one minute I was able to compile and the next minute it returns Live Coding errors.
It’s indicating I need to terminate before the pointer. Any insight would be grateful. Thank you.

MyPawn.h

UCLASS()
class PAWN_API AMyPawn : public APawn
{
	GENERATED_BODY()

public:
	// Sets default values for this pawn's properties
	AMyPawn();

	UPROPERTY(EditAnywhere)
	UStaticMeshComponent* CubeMesh;  

	UPROPERTY(EditAnywhere)
	UCameraComponent* Camera;

Paste in the complete MyPawn.h file.

Try #include "Camera/CameraComponent.h". If you use Rider you can just Alt-Enter on the UCameraComponent identifier and it will offer to do this for you. It will also show the UCameraComponent identifier in red to let you know there is a problem.

In your header you need to forward declare UStaticMeshComponent and UCameraComponent by addling class before the type. Then in your C++ you need to include their respective header.

UPROPERTY(EditAnywhere)
class UStaticMeshComponent* CubeMesh;  

UPROPERTY(EditAnywhere)
class UCameraComponent* Camera;

in your C++ add

#include "Camera/CameraComponent.h"
#include "Components/StaticMeshComponent.h"
