Getting an event from resulting actor hit result

Some insight, I’m making a tower defense game where tower components are stacked on top of foundations. I want to do a check before building the tower that the foundation can support it by checking how many tower components are already on the foundation. I’m doing a line trace from the tower builder to find the foundation

and I want to use that line trace to trigger a custom event in the foundation that performs a line trace to collect all of the current towers on top and count the total and prevent building if it is equal to the max build height.

My problem is that I can’t call the custom event because it’s returning a hit actor and not the specific foundation actor bp. Is there a way to convert the hit actor to the actor that contains the custom event or is there a different way to approach this?

Just cast it no?:

( I know the names are all wrong, but you get the idea… )

Thank you, I realized this after I posted this and I can’t believe I spaced on the cast. I had been working for so long my brain forgot how to do the simple things
