Mathf.LerpAngle

static function LerpAngle (a : float, b : float, t : float) : float

Description

Same as Lerp but makes sure the values interpolate correctly when they wrap around 360 degrees.

Variables a and b are assumed to be in degrees.

var minAngle = 0.0;
var maxAngle = 90.0;
// Fades from minimum to maximum in one second
function Update () {
var angle = Mathf.LerpAngle(minAngle, maxAngle, Time.time);
transform.eulerAngles = Vector3(0, angle, 0);
}
