Problem with click-to-move script

I have this kind-of standar scrip for moving to a clicked position:

// The target we are following var target : Transform; // The distance in the x-z plane to the target var distance = 10.0; // the height we want the camera to be above the target var height = 5.0; // How much we var heightDamping = 2.0; var rotationDamping = 3.0;

// Place the script in the Camera-Control group in the component menu @script AddComponentMenu("Camera-Control/Smooth Follow")

function LateUpdate () { // Early out if we don't have a target if (!target) return; // Calculate the current rotation angles var wantedRotationAngle = target.eulerAngles.y; var wantedHeight = target.position.y + height; var currentRotationAngle = transform.eulerAngles.y; var currentHeight = transform.position.y; // Damp the rotation around the y-axis currentRotationAngle = Mathf.LerpAngle (currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime);

// Damp the height currentHeight = Mathf.Lerp (currentHeight, wantedHeight, heightDamping * Time.deltaTime);

// Convert the angle into a rotation var currentRotation = Quaternion.Euler (0, currentRotationAngle, 0); // Set the position of the camera on the x-z plane to: // distance meters behind the target transform.position = target.position; transform.position -= currentRotation Vector3.forward distance;

// Set the height of the camera transform.position.y = currentHeight; // Always look at the target transform.LookAt (target); }

The problem is that, when I click to far from the object, it moves toward the click at an insane speed, evading all the colliders in the way ¿Any idea of how to solve it? Thanks!!!!
