Here is a bit of code that recalculates a path when you reach the end. There are no speed issues moving from one path to the next. There is sometimes just a bit of roughness in the LookAt() during the transition (and this may be solvable). Note I'm using iTween.PointPonPath() and iTween.PutOnPath() for a bit more control. To test this code:

• Create a large plane with position (0,-.5,0) and scale (100,100,100).

• Put a texture on the plane so you can see movement

• Add a cube at the origin

• Add a directional light to see the cube and the plane

• Add a Smooth Follow script to the camera with the cube as the target

• Add the following script to the cube

  ---

  pragma strict

  var angle = 20.0; // Maximum angle offset for new point var speed = 8.0; // Units per second private var pos = 0.0; private var segLength = 2.0; private var path = new Vector3[100];

  function Start () { path[path.Length-2] = Vector3.zero; path[path.Length-1] = Vector3(0,0,segLength); RecalcPath(); }

  function Update () { iTween.PutOnPath(gameObject, path, pos); var v3 = iTween.PointOnPath(path, Mathf.Clamp01(pos+.01)); transform.LookAt(v3); pos = pos + Time.deltaTime * speed / path.Length; if (pos >= 1.0) { pos -= 1.0; RecalcPath(); } }

  function RecalcPath() { var v3 = path[path.Length-1] - path[path.Length-2]; path[0] = path[path.Length-1]; for (var i = 1; i < path.Length; i++) { var q = Quaternion.AngleAxis(Random.Range(-angle, angle), Vector3.up); v3 = q * v3; path[i] = path[i-1] + v3; } }

The code walks a cube on the XZ plane. It generates the path in equal length segments and uses 'angle' to generate a random direction within an angle of the previous segment at each point.
