Can you be a bit more descriptive?
Do you mean independently of the player?
You can use the camera override Lua commands to do this, they are listed in global.lua:
SetCameraOverride : SetCameraOverride ( i ) where i is 0-off, 1-position only, 2-angle only, 3-position and angle
SetCameraPosition : SetCameraPosition ( c, x, y, z ) where c should be zero and XYZ are 3D coordinates
SetCameraAngle : SetCameraAngle ( c, x, y, z ) where c should be zero and XYZ are euler angles
GetCameraPositionX : V = GetCameraPositionX ( c ) where V is the X coordinate of the specified camera
GetCameraPositionY : V = GetCameraPositionY ( c ) where V is the Y coordinate of the specified camera
GetCameraPositionZ : V = GetCameraPositionZ ( c ) where V is the Z coordinate of the specified camera
GetCameraAngleX : V = GetCameraAngleX ( c ) where V is the X angle of the specified camera
GetCameraAngleY : V = GetCameraAngleY ( c ) where V is the Y angle of the specified camera
GetCameraAngleZ : V = GetCameraAngleZ ( c ) where V is the Z angle of the specified camera
Been there, done that, got all the T-Shirts!
