Compile issues

Unreal Courses Talk

#1

I have the following headers #include “Grabber.h”
#include “Engine/World.h”
#include “GameFramework/Controller.h”
#include “GameFramework/Actor.h”
#include “Engine/TriggerVolume.h”
#include “GameFramework/PlayerController.h”

I have the following code:
void UGrabber::TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
{
Super::TickComponent(DeltaTime, TickType, ThisTickFunction);
FVector PlayerViewPointLocation;
FRotator PlayerViewPointRotation;

GetWorld()->GetFirstPlayerController()->GetPlayerViewPoint(
	PlayerViewPointLocation,
	PlayerViewPointRotation
);



UE_LOG(LogTemp, Warning, TEXT("Location: %s, Rotation: %s")
	*PlayerViewPointLocation.ToString()
	*PlayerViewPointRotation.ToString()
)

// ...

}
(I skipped the define Out step to help troubleshooting)

I get the following errors:

For the life of me, I’ve tried a lot of combinations, just can’t seem to get this to compile.

#2

Follow up: It’s the %s step that seems to be the issue somewhere near there. It works fine if I just remove the %s and references after. But of course, without that I can’t complete the exercise.

#3

Well, I don’t know how to delete stuff here, but I found the issue. I kept getting issues saying it had something to do with “(” but in fact I just forgot a comma. After the TEXT(“X”) make sure you include a comma.

#4

Yup… syntax matters!
Often when you see a whole mess of errors like that its from a missing separator because the compiler has lost track of where to parse things.
(At least you didn’t blame the engine!)
