Does anyone know if it is possible to change the value of Mouse Y > Invert in the default Unity Input Manager through script? There are so many things that you can change in Unity's predetermined settings that I figure that this has to be possible, no?
This is not possible with the default Unity Input Manager, you could look for a custom one like http://forum.unity3d.com/threads/53726-Custom-Inputmanager-v1.4-VERY-easy-to-use-now-!
