// and half of the original one

var duration : float = 3.0; var originalRange : float;

var lt: Light;

function Start() { lt = GetComponent.<Light>(); originalRange = lt.range; }

function Update() { var amplitude : float = Mathf.PingPong(Time.time, duration);

// Transform from 0..duration to 0.5..1 range. amplitude = amplitude / duration * 0.5 + 0.5;

// Set light range. lt.range = originalRange * amplitude; }
