Need some help with Spawn Actors' transform

In my BP I tried to use FP_Gun as startpoint. But as you know this mesh has custom rotation, so at first I change rotation, and then make transform with its location. But have a problem. I need send my projectile from a custom vector. From FP_GUN to another location in space. And I not fully understand how it must be done…

P.S. As can you see, I wanna send my projectile along traced line… this line must be as waypoint, but I can’t do it itself. I’m very newbie with UE… So you can help me… thx a lot.

How about Get Forward Vector between the start and end Locations you used to make the trace and GetRotationFromVectorX (or whatever it’s called) and set you projectile’s direction with that?

I not fully understand what I do, but did it yet
