Any Object implementing an Interface as parameter

[RelaX92]

@Jambax

Given the example code you showed, you cannot just call that function on any random object. You can only call it on an object which implements the interface, and therefore you already have to know whether it implements it or not, and already have a reference to it. It’s no different in Blueprint.

Either way, both of these functions compiled fine for me - and gave me a node with an interface pin on the return. Obviously in this example the interface is null, in reality you would have to populate it with something.

I didn’t asked to call it on any object, I want to call it on any object implementing the interface. My only problem was that I coudln’t get it to compile.

Hi Relax,

I’ve rewritten your code slightly so that it does (what I think you want?)

Yeah, that’s pretty much why I also wanted to return it, but I think I will use a different approach, more like a state machine. But I still need to pass the interface and returning it might still be useful.

So, thanks for the correct syntax TheJamsh and Gossy, I also tried to add ‘&’ after I looked into the generated gen.cpp and at the TScriptInterface constructor, but really wasn’t sure about it.
