Making projectiles move to a tapped object- Mobile

Hey guys,

I’m currently writing a script in which a projectile is shot each time an asteroid is tapped. My only problem is that I want the projectile to shoot toward the asteroid by looking at it. I’ve tried to make the origin of the projectile (named Shooter) look at the asteroid but haven’t had any luck. I’m unsure of where to go from here and could really use a nudge in the right direction. My code is below, thank you for your help.

var Shooter : Transform;
var Asteroid : Transform;
var projectile : Rigidbody;

function Update()
    //check for touches
    if (Input.touchCount > 0)
        //grab touch
        var t = Input.touches[0];   

        //check if it's the beginning of a touch
        if (t.phase == TouchPhase.Began)
            //shoot a ray from the touch position into the scene
            var ray = Camera.main.ScreenPointToRay(t.position);
            var hit : RaycastHit;
            if (Physics.Raycast(ray, hit)) //check if the ray is hitting something
        var clone : Rigidbody;
        clone = Instantiate(projectile, transform.position, Asteroid.rotation);
        clone.velocity = transform.TransformDirection (Vector3.up * 45);

You aren’t setting the asteroid to anything. I’m guessing you need to do this:

Asteroid = hit.collider.gameObject;

Then tell Shooter to look at the asteroid.

Also; pre-empting another possible problem; I’m pretty sure you want to use your transform.forward in the velocity set. E.g. clone.velocity = transform.forward * 45;
