how to detroy an actor ( rocks ) with the characters fists ???

does anyone know how we can do for our character can destroy rocks placed on his way by hitting it ???

You just destroy the actor, with the DestroyActor node.

If the actors are static meshes, you’ll need to do some sort of trace ( line trace, sphere trace etc ) from the player, and destroy it that way.

If the actors are blueprints, you can send them a message using interfaces that they’ve been hit, and they destory themselves.
