# Is there a .Magnitude for orientation?

Is there a .Magnitude for orientation?
Or how do I calculate how close a rotational degree is to another rotational degree?

Can you explain what your trying to do a bit more clearly?

Are you trying to check the length from one angle to another angle?

Take the difference between both degrees using `math.abs`(because degrees aren’t always positive `math.abs` gets the absolute value of a number which is always positive)?

Since Orientation is a `Vector3` value, you can do something like this:

``````local FirstOrientation = Vector3.new(5, 5, 5)
local SecondOrientation = Vector3.new(10, 10, 10)

local OrientationDifference = (FirstOrientation - SecondOrientation)
local OrientationMagnitude = OrientationDifference.Magnitude

print(OrientationMagnitude) -- 8.66025447845459
print(OrientationDifference.X, OrientationDifference.Y, OrientationDifference.Z) -- -5, -5, -5
``````

Don’t forget to mark this post as a solution if this helped Yes. The is a `.Magnitude` for Orientation.

``````local Part = Instance.new("Part", workspace)
Part.Parent = workspace
local Goal = Part.Orientation+Vector3.new(40, 0, 0)

while true do
if Part.Orientation.Magnitude < Goal.Magnitude then
Part.Orientation += Vector3.new(1, 0, 0)
else
Part:Destroy()
print("Part reached the goal.")
end
end
``````

Turn them into vectors and do math.acos(direction1:Dot(direction2)) ?

No, there is not. Simply because rotation resets and is clamped to 180 degrees, so moving past that resets it and will provide an inaccurate measurement. However, this doesn’t apply to unit vectors like `LookVector`, but they always have a magnitude of one, unless you meant a comparison of two.

Edit: you can also compare the rotation using the dot product, though it is only one axis.

For that you need to use the Dot Product:

``````local orientation_1 = Vector3.new(90,0,0)
local orientation_2 = Vector3.new(0,90,0)

Remember! The angle will be in radians and not degrees! You can convert to degrees using `math.deg(angle_in_radians)`
