How do I add impulse to an actor?

I want to apply an impulse to all the actors within a box trigger but I am not sure how to get a static mesh or primitive from the array of actors.

I found out the cast I need to do! Casting to staticMeshActor lets you get the static mesh component which you can apply an impulse to!

Thanx you helped me :slight_smile:

Didn’t work for me since it was a custom actor class from which Static Mesh Component didn’t inherit from.
