player camera rotation property?

Its not a rotation property but Its the CFrame called CoordinateFrame you can use it like

camera.CoordinateFrame = CFrame.new(0, 0, 0)--x pox, y pos, z pos

CFrame have more than three numbers(position), they have others numbers used for the rotation You can set the rotation by using this function:

camera.CoordinateFrame = CFrame.new(0, 0, 0) *CFrame.Angles(math.pi, 0, 0)--math.pi is 180 degree

You can also use math.rad a function in the math library

camera.CoordinateFrame = CFrame.new(0, 0, 0) *CFrame.Angles(math.rad(180), 0, 0)

Don't forgot to put your cameratype at Scripting for make it work

camera.CameraType = Enum.CameraType.Scripting

If you need to know more about CFrame or on the Camera you can use roblox wiki

Code:

--Make sure to put it in a local script in your player to make it work
local camera = game.Workspace.CurrentCamera
wait(1)
camera.CameraType = Enum.CameraType.Scripting
camera.CoordinateFrame = CFrame.new(5, 2, 1) *CFrame.Angles(0, math.pi, 0)
