How can I add an interface type input pin?

How can I make the function input parameter as an interface?

It does not appear in the pin type tab, how can I add it?

I can’t do it at all.

You can’t pass pointers to functions in blueprint, as far as I’m aware :melting_face:

I saw it in another project and I want to add it to the function I created in this way. The one in the photo is a special function and it works.

It’s a very small picture ( can’t read it ), but from the color, I’d say the type of that pin is ‘class’.

What sort of class, I have no idea, but it’s not a function pointer

it’s an actor component class reference, but it really could be anything.
