Unreal Engine 4 -- Casting

Question

I am currently developing my first classes in Unreal Engine 4. Coming from using UScript extensively, I'm getting a little bit confused by how typecasting works in pure C++. More specifically, class/object casting.

I am currently putting together a switch statement in MyCustomGameMode which calls upon MyCustomPlayerController for MyCustomPlayerControllerVariable.

The function in question that I am overriding is this one: virtual UClass* GetDefaultPawnClassForController(AController* InController);

Currently I'm trying to call the variable with the following line of code, which I know is incorrect, but I'm not sure why:

Cast<MyCustomPlayerController>(InController).MyCustomPlayerControllerVariable

I am interested in casting the "InController" to MyCustomPlayerController but Cast<MyCustomPlayerController>(InController) doesn't seem to work, what am I doing wrong here?

I flagged this as normal programming question, but i was wrong. It is related to game programming as this is UScript. — Katu, Jul 01 '14 at 06:08
@Katu it’s definitely not UScript; the author just said he/she was used to UScript from UE3. — sam hocevar, Jul 01 '14 at 07:06
So is it supposed to be 100% true C++ or some dialect with almost identical syntax? — Mario, Jul 01 '14 at 07:12
@SamHocevar Yeah, yeah. Should not come here before morning coffee. — Katu, Jul 01 '14 at 07:12
@Mario it’s 100% C++ (with some build-time generation of headers). — sam hocevar, Jul 01 '14 at 07:15
@Guest102 “is incorrect”, or “doesn’t seem to work” is not a helpful description of your problem. Be more specific. — sam hocevar, Jul 01 '14 at 07:17

Cast<Foo> returns a Foo *. So the proper way to access your variable should be:

Cast<MyCustomPlayerController>(InController)->MyCustomPlayerControllerVariable
