How to use BP to calculate 2 actors link like Parent/Child Effect?
I know can use attach or parent socket to make Parent/Child Effect.
I can just use get forward vector to so 1 parent direction

If you want to rotate one actor to another, use vectors.

actor1location - actor2location -＞ normalize. this will be direction.

then -＞ MakeRotFromX(direction)
