Having trouble with simple Blueprint communication

I’m trying to have my first BP to ask the 2nd to do something though a “Get Actors of Class” cast. When using the breakpoint, I can see that the Cast is being called, but fails to execute the function on the other BP. But the cast apparently isn’t failing because I attached a quit game node to it and it didn’t quit.

Your cast it gonna fail for sure coz you don’t have any thing to connect to object pin of Cast, and for fail i don’t know what node u use but maybe u make a print string to check instead.

Oh I see. It doesn’t look like I can connect anything to it though. When I drag the squares to the object, it says that I can’t do this. What could I connect to it?

that is array you need a for each loop to do that

It worked. Thank you!
