Any tricks for determining what parameter a node takes.


I was trying to get play sound attached node to work the other day. I was suppose to have used another node to play a sound, my bad. But one thing that I had trouble with is determining what parameter goes with Attached to Component. I tried dragging a wire from that location hoping that it can give me some helpful hints but it gave me hints that were not compileable. Any suggestions that I can use so that I wont ever get stuck trying to figure out what parameter to use? This is the link:

I didn’t help me in determining what parameter goes there. I did take a look at USceneComponent class, but I seen a bunch of functions and variables and that is about it.

Thanks in advance for any useful advice.
