Quaternion.Angle

static function Angle (a : Quaternion, b : Quaternion) : float

Description

Returns the angle in degrees between two rotations a and b.

JavaScript

// Calculates the angle (degrees) between
// the rotation of this transform and target.

var target : Transform;

function Update () {
    var angle : float = Quaternion.Angle(transform.rotation, target.rotation);
}
