Need help getting an angle

[KUW_Alt1 (Kuw)]

So if I had a two parts on the same z axis, then how would I get the angle from one another?
Just know this isn’t using screen gui’s, this is using parts.

Position1 = ...
Position2 = ...

Dot = Position1:Dot(Position2)
Angle = math.acos(Dot/(Position1.Magnitude * Position2.Magnitude))

Note that angle will be in radians, and may need to be subtracted from 90 or pi/2 depending on if it got the right angle or not.

@SeargentAUS

math.arccos

doesn’t exist

maybe it’s

math.acos()

I’ll check

edit: Yeah it should be math.acos(). I have corrected my previous post
