My Part's Orientation sets to 0, when I CFrame it??

Basically, when you click the script, the Part is supossed to Go on a position, after 5 seconds to come back, however when it comes back, the Orientation sets to 0, how can I fix this?

local part = script.Parent


local click = script.Parent.ClickDetector

click.MouseClick:Connect(function(click)
    print("I got clicked")
part.Orientation = part.Orientation + CFrame.new(0, 90, 180)
    script.Parent.CFrame = CFrame.new(1304.292, 235.142, -665.739) 
    wait(5)
part.Orientation = part.Orientation + CFrame.new(0, 90, 180)
    script.Parent.CFrame = CFrame.new(1284.227, 237.592, -668.21)
end)

Hello.

Solution:

Use CFrames.Angles instead of orientation as CFrames cannot be added to Orientation (Vector3). Also, CFrames are rotation and position, so you don't need to use orientation.

Fixed code:

local part = script.Parent


local click = script.Parent.ClickDetector

click.MouseClick:Connect(function(click)
    print("I got clicked")
	part.CFrame = part.CFrame * CFrame.Angles(0, math.rad(90), math.rad(180))
    script.Parent.CFrame = CFrame.new(1304.292, 235.142, -665.739)  * CFrame.Angles(0, math.rad(90), math.rad(180))
    wait(5)
part.CFrame = part.CFrame * CFrame.Angles(0, math.rad(90), math,rad(180))
    script.Parent.CFrame = CFrame.new(1284.227, 237.592, -668.21) * CFrame.Angles(0, math.rad(90), math,rad(180))
end)

Someone on Discord Helped me: This is the way how to Rotate and CFrame at the same time, and it works fine!

part.CFrame = CFrame.new(1300, 237.6, -665.8) * CFrame.Angles(0, math.rad(90), math.rad(180))
