In 4.24.3 the declarations have to be without the const, so
in the .h:
virtual void GetAudioListenerPosition(FVector& OutLocation, FVector& OutFrontDir, FVector& OutRightDir);
and in the cpp:
void APlaneshiftPlayerControllerBase::GetAudioListenerPosition(FVector& OutLocation, FVector& OutFrontDir, FVector& OutRightDir)
The line:
Super::GetAudioListenerPosition(OutLocation, OutFrontDir, OutRightDir);
to me its unecessary as it will just execute the same code in the super class APlayerController. I removed it and it works anyway.
