Eye Driver

I’m using a Eye Driver for movements for the eye and eye lids and was wondering is there a way to get this in the Blender In Game feature rather than a Render would this require some extra coding? Also would it be possible to code a night and day cylcle that works in game? Any help or replys would be appreciated.

What do you mean by a night and day cycle?

If you mean a animation key for a night face distortion and day, then yes you can mix action keys to get an squint etc
