Unity 3D Developer Interview Question:

Consider the following code snippet below:

class Mover : MonoBehaviour
{
Vector3 target;
float speed;

void Update()
{

}
}
Finish this code so the GameObject containing this script moves with constant speed towards target, and stop moving once it reaches 1.0, or less, units of distance?

class Mover : MonoBehaviour
{

Vector3 target;
float speed;

void Update()
{
float distance = Vector3.Distance(target,transform.position);

// will only move while the distance is bigger than 1.0 units
if(distance > 1.0f)
{
Vector3 dir = target - transform.position;
dir.Normalize(); // normalization is obligatory
transform.position += dir * speed * Time.deltaTime; // using deltaTime and speed is obligatory
}
}
}
