move gameobject into a random position and the spawn an enemy

hello, this is the script that I did.

void Start () 
{
	posFinale = new Vector3(Random.Range (-17.0f,18.0f),Random.Range (-10.0f,11.0f),0);
}

void Update () 
{
	transform.Translate ((posFinale - transform.position)* speed * Time.deltaTime);

	if ((transform.position == posFinale) && !(fatto))
	{
		fatto = true;
		Instantiate(add,transform.position, Quaternion.identity);
		Destroy (gameObject);
	}
	Debug.Log (posFinale);
}

But I have a problem, when it comes to the location is not that precise so do not spawn the enemy.

I also tried with vector3.lerp but does the exact same thing

Is there another way to do this?

As @iwaldrop suggests, Vector3.MoveTowards() will work. Lerp() will work if you in a linear fashion (i.e. the final parameter be an increasing fraction between 0 and 1. You can also make your existing code work. The problem is this check:

 if ((transform.position == posFinale) && !(fatto))

The chance of transform.position being exactly equal to posFinal is small. So you can instead do the check this way:

if (Vector3.Distance(transform.position, posFinale) < threshold && !(fatto))

‘threshold’ is either a variable you define or some constant. It is a small value that defines close enough.
