Light.spotAngle

Description

The angle of the light's spotlight cone in degrees.

This is used primarily for Spot lights and has no effect for Point lights See Also: Light component.

// Change spot angle randomly between 'minAngle' and 'maxAngle'
// each 'interval' seconds.

var interval : float = 0.3;
var minAngle : float = 10;
var maxAngle : float = 90;
var timeLeft : float;


var lt: Light;


function Start() {
	lt = GetComponent.<Light>();
	lt.type = LightType.Spot;
	
	timeLeft = interval;
}


function Update () {
	timeLeft -= Time.deltaTime;
	
	if (timeLeft < 0.0) {
		// time to change!
		timeLeft = interval;
		lt.spotAngle = Random.Range(minAngle, maxAngle);
	}
