I try to create a function to automatically get the first Actor with a specific Interface in the scene but I don’t know how to set the parameter type to “Interface” class.
The “Interface” type seems to exists but it does not show up in the context menu.
( Create with drag & drop from “Get All Actors With Interface” → Promote to variable… )
How I set the parameter type of my function to this “Interface” class type ?
Just drag here, and it will make the correct type
( drag into a blank area, not onto the existing pin )
Ohh! Haha! Nice, thank you!
Neat trick.
Also useful is right clicking on a pin and choosing ‘promote to variable’ 
Yes, indeed. That is how I created the “New Local Var 1” of class type Interface. Without this I wouldn’t even know that this Interface type can be used inside Blueprints.
