Maxscript: finds the angle between two vectors

Finding Angle Between Two Vectors | .ms

-- Option 1
fn GetVectorsAngle v1 v2 =
(
	theAngle = acos(dot (normalize v1) (normalize v2))
)
vA = obj2.pos - obj1.pos -- vector between two objects
vA = obj3.pos - obj1.pos -- vector between two objects
GetVectorsAngle vA vB


-- Option 2
v1 = [4,3,0] - [0,3,10]
v2 = [3,0,0] - [0,2,10]

v1 = [4,0]
v2 = [3,-2]

nv1 = normalize v1
nv2 = normalize v2

dotProduct = (nv1.x * nv2.x) + (nv1.y * nv2.y)
