I need to get a rotation from two transform position
let's say I have two objects a and b and I know their transform. I need to instantiate an object that'll face the same direction as the direction from object a to b .How do I get that rotation? In my game(it's 3d ) y is the upwards direction. I have tried but I can't seem to wrap my head around quaternions.
So if object A is facing object B, just set the rotation of the new instantiated object to equal the rotation of object A.

GameObject go = Instantiate( ... ) ;
Vector3 aPosition = a.GetComponent<Transform>().position ;
Vector3 bPosition = b.GetComponent<Transform>().position ;
Vector3 direction = bPosition - aPosition ;
go.GetComponent<Transform>().rotation = Quaternion.LookRotation(direction, Vector3.up);
