I figured it out, cool man. It sets the delay time b4 the camera follows you. Setting it to 0 makes the camera stay in one fixed place while you run around until the camera loses line of sight, then it resets to a new position where it can see you again, as in the Tomb Raider games. Anything between 0 & 1 will allow the camera to follow after a certain distance or time delay. 1 must be the default, or at least that's where I'm going to leave it from now on.
Very cool Egg!
