Rotation prints 0

I have tried several methods of printing the rotation of a part or model, none of them have worked

now heres an example:

local x, y, z = workspace.Car.WorldPivot.Rotation:ToOrientation()
print(math.deg(x), math.deg(y), math.deg(z))

it just returns 0

and here too:

local x = workspace.musicPart.CFrame.XVector.X
local z = workspace.musicPart.CFrame.XVector.Z
print(x,z)

they print some long numbers but its always 1 or 0 idk
and here:

local x = workspace.musicPart.CFrame.X
local z = workspace.musicPart.CFrame.Z
print(x,z)

and here i get 0 too:

local x = workspace.musicPart.Rotation.X
local z = workspace.musicPart.Rotation.Z
print(x,z)

same as here:

local x = workspace.musicPart.Orientation.X
local z = workspace.musicPart.Orientation.Z
print(x,z)

they all don’t print the rotation, ive been struggling for around 2 hours and i can’t figure it out, but they do work if i rotate them before test playing, but if i rotate them in the game nothing happens. please i need help!

When you test, by default you are a Client, so changing the rotation of something will not be visible to a server script. Could that be it?

no, i dont know but im trying to make like a system if the car is flipped that it rotates but ignore that, im focusing on how i could print the rotation of the car, but they print 0

Do you actually need 3 rotation angles or just whether the top of the car is facing up?

I need the rotation angles so i can flip the car if the angle is above 45 or under -45
if theres a different method than rotation so the car gets back up with bodygyro tell me

you could always do this to check if the car is upside down:

local orientation_angle = math.acos(workspace.Car.WorldPivot.UpVector:Dot(Vector3.yAxis))

if (orientation_angle > math.pi/4) then
    --flip car
end

it doesnt do anything, not even printing

#8

print orientation angle outside of the if statement. Make sure that the part your checking has the upvector actually facing up

#9

i did and its still printing 0

Actually the issue might be world pivot. I’m not sure if it actually takes rotations of the parts within the model into account. If you have a primary part inside the model, it may be better to use GetPrimaryPartCFrame instead for reading the models cframe

#11

this kind of works:

workspace.Car:GetPrimaryPartCFrame(Vector3.xAxis)

but it gives me these numbers:
-16.3778706, 3.92321491, 167.306717, 0.999997079, 0.0016545197, 0.00172889291, -0.00165881298, 0.99999553, 0.0024848457, -0.00172479253, -0.00248770649, 0.99999541

the numbers -16.3778706, 3.92321491, 167.306717 is the position of the part it printed that out but how do i print the rotation?

(I don’t know if im using it right)

#12

do this

local orientation_angle = math.acos(workspace.Car:GetPrimaryPartCFrame().UpVector:Dot(Vector3.yAxis))

if (orientation_angle > math.pi/4) then
    --flip car
end

The WorldPivot property will be relative to the PVInstance, not to the world. What you’re looking for is model:GetPivot():ToOrientation()
