After some initial experimentation, I’ve made a few “interface” classes, which are operating as I expect them to. (I had a hard time finding reference material, but some answerhub searching turned up this, which was helpful).
I want my own interface classes to provide some mix-and-match style features to my AActor and APawn classes, and that part’s working fine. But it seems you cannot use a UPROPERTY in an interface class, so if I want the interface to hold any state of its own, I have to manage the serialization myself. I don’t want my interface class to be a first class AActor or even UObject, because class size is a concern.
Am I correct that I must manage the serialization myself for such classes? It’s not hard, but if there’s a better approach, I’d sooner avoid my own serialization if I can.
Also, is there any way to pass values into the constructors of interface classes, such as:
AMyPawn::AMyPawn() : IInterface_Whatever(4.0f, "hi", etc) { ... }
I tried this and the generated content tool became quite unhappy :).
