you basically just need to have a way to reference the actor your overlapping so that you can damage them. below is a little example i threw together that should work in your situation, though im sure theres a better way to go about it. what i did is when the input is pressed i got all actors of the class that can be damaged then for each one i checked to see if i was overlapping their damage box. if true then i apply damage. the cast should be superfluous but my editor was being weird about it so i added it in.
