Get an Object to Face/Move to RayCast Hit.point?

Hey! I was wondering how to get an object to move where the raycast ends or hits a collider. What I want to do is instantiate a bullet that always goes where the player shoots (so to check where that is, using RayCast). Anybody know how to do that? A script example would be much appreciated!

This could be the bullet script:

Vector3 endPoint = Vector3.zero;
float      speed = 50f;

void SetEndPoint(Vector3 p)
{
    endPoint = p;
}

void Update()
{
    if(endPoint != Vector3.zero)
        transform.position = Vector3.MoveTowards(transform.position, endPoint, Time.deltaTime * speed);
}

Where you create the bullet you get a reference to it and send it the SetEndPoint function:

Transform bullet = Instantiate(...);
bullet.SendMessage("SetEndPoint", hit.point);

Furthure more if you are shooting at objects that might get destroyed, you could also send that object’s reference to the bullet too, by adding a variable and a function for it:

Transform enemy;

void SetEnemy(Transform e)
{
    enemy = e;
}

Then you should add a direction variable for the enemy direction, so if the enemy is dead before the bullet hits him, it continues in the same direction:

Vector3 enemyDirection;

void Start()
{
    enemyDirection = (enemy.position - transform.position).normalized;
}

And you would add to the Update:

void Update()
{
    if(endPoint != Vector3.zero)
        transform.position = Vector3.MoveTowards(transform.position, endPoint, Time.deltaTime * speed);
    if(enemy)
        transform.position = Vector3.MoveTowards(transform.position, enemy.position, Time.deltaTime * speed);
    else
        transform.position += enemyDirection * Time.deltaTime * speed;
}
