Gradually changes an angle given in degrees towards a desired goal angle over time.
The value is smoothed by some spring-damper like function. The function can be used to smooth any kind of value, positions, colors, scalars. The most common use is for smoothing a follow camera.
// A simple smooth follow camera, // that follows the targets forward direction var target : Transform; var smooth = 0.3; var distance = 5.0; private var yVelocity = 0.0; function Update () { // Damp angle from current y-angle towards target y-angle var yAngle : float = Mathf.SmoothDampAngle(transform.eulerAngles.y, target.eulerAngles.y, yVelocity, smooth); // Position at the target var position : Vector3 = target.position; // Then offset by distance behind the new angle position += Quaternion.Euler(0, yAngle, 0) * Vector3 (0, 0, -distance); // Apply the position transform.position = position; // Look at the target transform.LookAt(target); }
