How to set up projectile owner

So i did this animation that spawn’s actor “rock”, i want to launch it into other player by using another animation on it so it will apply damage to them on hit and i want to other player to do the same to me but when i spawn it and i touch it, it does damage to me and i want it to dont do damage to spawning person. I used this blueprint for now (i’m new in unreal)
