Attempt to index nil with 'CFrame'

Help and Feedback Scripting Support
#1

The error showed me this

wait(1)

if script.Parent.Parent.Parent.Parent.Parent:FindFirstChild(“MainParts”) then

script.Parent.Engine.Value = script.Parent.Parent.Parent.Parent.MainParts.Engine

end

local roll = script.Parent.Engine.Value

local Engine = script.Parent.Engine.Value

while game:GetService(“RunService”).RenderStepped:wait() do

script.Parent.union.Rotation = math.deg(math.atan2(Engine.CFrame.lookVector.y,Engine.CFrame.lookVector.y))

end

#2

How are you getting ‘Engine’. If this is your full script then it is erroring because you didn’t define any Engine variable.

#3

There is no such thing as “Rotation”, You meant “Orientation”

#4

Make sure the value of script.Parent.Engine is actually set to a part.

#5

It now says [ invalid argument #3 (Vector3 expected, got number)]

#6

That’s probably from trying to set the rotation. Rotation/Orientation is a vector3, not just one number.

#7

Please format your scripts before posting them

The error is probably occurring because Engine is nil, make sure it has a value.
If you want to change the rotation of an object you would do this instead

part.CFrame = CFrame.new(part.Position) * CFrame.Angles(X, Y, Z) -- // You need to specify X, Y and Z in radians! you can do math.rad(num) to convert from degrees to radians. // --
