Knockback in given direction

Hi!

I want to launch the character based on where he was hit, but I havn’t found any way to transfer this information between blueprint. My attacker casts a multiboxtrace for object and then apply damage, and my receiver does an event AnyDamage and lose health and then do a launch character, in a single direction, that disable him.

I wanna give him a launch in the opposite direction of where he was hit.
Also, I would like to do some attack, for example combo, that doesn’t launch the character.
