Try doing a linepick downwards, a short distance. If the picked distance is greater than the player collision sphere, he's not touching the ground, so apply gravity to him :)
This is a linepick example.
USE arrow keys to move, and spacebar to jump. Line pick used to see if the cone is still 'jumping'
