problem with mouseclicke movement

Question

I have a code which I also got from the internet. Here is the code:

var smooth:int; // Determines how quickly object moves towards position

private var targetPosition:Vector3;

function Update () { if(Input.GetKeyDown(KeyCode.Mouse0)) { var playerPlane = new Plane(Vector3.up, transform.position); var ray = Camera.main.ScreenPointToRay (Input.mousePosition); var hitdist = 0.0;

     if (playerPlane.Raycast (ray, hitdist)) {
         var targetPoint = ray.GetPoint(hitdist);
         targetPosition = ray.GetPoint(hitdist);
         var targetRotation = Quaternion.LookRotation(targetPoint - transform.position);
         transform.rotation = targetRotation;
     }
 }
 transform.position = Vector3.Lerp (transform.position, targetPosition, Time.deltaTime * smooth);

}

the problem with this code is that when I click to one place. my character is only facing to the place where I clicked and does not move there. do you know whats missing in this program? and also how will I be able to put the animation walk that after the character moved to the position it wil return to idle animation.. thanks

The only weird thing in your code is smooth being an int - it should be a float. But as far as I know, int float* results in a float, thus this should not kill the movement. Declare smooth as float and assign a reasonable value (5 takes about 1 second).
Another suggestion: the movement above will start fast and slow down near to the destination. If you want a constant speed, use Vector3.MoveTowards:

   transform.position = Vector3.MoveTowards(transform.position, targetPosition, speed * Time.deltaTime);

Where speed is in meters per second. As occurs with Lerp, the object will never pass the targetPosition.

yes @berting01
var smooth : float = 2 ;
or var smooth : float = 23.0434 ;
... or whatever so long as its a numeric value ;
Don't forget to mark aldo's answer as the accepted if it helped you out.
