I have a couple questions about best c++ practices:

I’m having trouble getting help on the discord server because of my time zone, so here’s a couple questions regarding c++:

  1. If I’m trying to store and pass
    around an object that I know
    implements an interface, but I don’t
    know anything else about, should I
    set the variable type to be
    IInterfaceName , TScriptInterface,
    UObject*, or something else? How
    should I call BlueprintNativeEvent
    functions and other functions in the
    object using the given variable
    type?
  2. If I want an optional argument for a
    UFUNCTION that will default to a
    value if un-specified, what should I
    do?
  3. Does Tick() run before or after
    BeginPlay()?

If you know the answer to any of these, help would be much appreciated. Thanks.

  1. I would store it as a UObject*. But inorder to call non interface functions on it you are going to need a reference of the correct type.

  2. Assign the default value to the argument inside argument list.

  3. After. This would be easy to test by putting a ue log in both and seeing what gets printed first.

I hope this helps!

In the argument list of the header or cpp?

Header. You could also add it to cpp if you want.
