CameraDirectionX() and the other two vectors:
Documentation says
Return value

Returns the 'x' direction vector of the camera. This value is always between -1.0 and 1.0.

Since a direction vector cannot be specified with a scalar this should return 3 components specifying the vector.

Also there should be a function to set the direction for the X axis of the camera like SetCameraXDirection(x,y,z).
Using CameraLookAt the Z axis can be specified. Then there is no need to specify the Y direction when the X and Z have already been specified. Instead of X we should have the option to set the Y axis of the camera. Mostly this would be directed parallel to the world Z axis, or upward ( if you use Z coordinate of the World perpendicular to the ground).

Thanks

This sounds more like a feature-request.
So moved to this sub-forum for further investigation by the programmers.

This looks more like a mistake in the helps files to me.
I think it would be better if the help files said something like CameraDirectionX() returns the X value of the Camera's directional view vector. The same thing could be said for CameraDirectionY() and CameraDirectionZ().

It seems to me like you want the ability to manually adjust the Camera's View, Right, and Up vectors.
Not sure if I agree with adding those commands though. It can be risky because if you incorrectly calculate the vectors the scene will be distorted.

To be investigated by Fred or comtois...
