I have a trigger box with an overlap begin event and i want to add a upward impulse against gravity to my current player character which is (other actor), but i cannot connect this actor to the “add impulse” or “set linear velocity” 
I tried “get player controller” and “get player character” without any success… the impulse is fired, but nothing happens.
I think my general question is, how do i properly retrieve components from actors??
So that i can use the physic methods to do stuff or change the location whatever.
