Hey,
If your doing singleplayer only, I believe its something like this
()->GetFirstPlayerController()
Or I believe
UGameplayStatics::GetPlayerController((), 0);
With any world action you should double check its valid first so I would guess -
if (())
{
UGameplayStatics::GetPlayerController((), 0);
}
Update: Oh and just a handy tip if your new to C++. Get a copy of Unreal source code from github or just have github open on the UE page. If you want a function like getInput, run a search on github for that, and you can check how epic implement it. This is basically how I do all my coding.
