GameTime
GameTime rotates a directional light to match the appropriate direction of the sun for the system time of day.
TODO: It doesn't change the length of the day for seasons nor the angle of the sun. It also doesn't turn off the light at night, as would be accurate.
Code
import System; var date = DateTime.Now; var timeDisplay : GUIText; function Start() { InvokeRepeating("Increment", 1.0, 1.0); } function Update () { var seconds : float = date.TimeOfDay.Ticks / 10000000; transform.rotation = Quaternion.LookRotation(Vector3.up); transform.rotation *= Quaternion.AngleAxis(seconds/86400*360,Vector3.down); if (timeDisplay) timeDisplay.text = date.ToString("f"); } function Increment() { date += TimeSpan(0,0,0, 1); }
