I recently started learning UE5, im following a tutorial and i have been getting errors non stop and i dont really understand why.
I created the AARollaBallPlayer script i fixed the folder creation error, but now that i have written the code i get more errors, can some one explain what im doing wrong cause working with UE5 so far has not been the best experience so far…
Edit: im using visual studio 2022.

The issue lies in the fact that the IImageWrapperModule is not included in your code, but it’s not actually used in the provided code snippet. However, I suspect that you might be using it elsewhere in your project.

To fix the identifier IImageWrapperModule is undefined error, you need to include the ImageWrapper.h file:

cpp

VerifyOpen In EditorEditCopy code

1#include "ImageWrapper.h"

This file is part of the Unreal Engine framework, so you should be able to find it in the engine’s include directory.

Regarding the incomplete type is not allowed error, it’s likely caused by a missing include file or a forward declaration. In your code, you have forward declarations for USpringArmComponent and UCameraComponent, but you’re missing the include files for these classes.

Add the following lines to your ARollaBallPlayer.h file:

cpp

VerifyOpen In EditorEditCopy code

1#include "GameFramework/SpringArmComponent.h"
2#include "Camera/CameraComponent.h"

Alternatively, you can move these includes to your ARollaBallPlayer.cpp file, if you prefer.

Here’s the updated code:

cpp

VerifyOpen In EditorEditCopy code

1// AROLLaBallPlayer.h
2#pragma once
3
4#include "CoreMinimal.h"
5#include "GameFramework/Pawn.h"
6#include "GameFramework/SpringArmComponent.h"
7#include "Camera/CameraComponent.h"
8#include "ImageWrapper.h" // Add this line if you're using IImageWrapperModule
