Raycast Shooting Help

http://docs.unity3d.com/Documentation/ScriptReference/Physics.Raycast.html

Think of it this way...

 var hit : RaycastHit      // This will store the thing we hit with our Raycast
 if(Physics.Raycast        // If we hit something
 (transform.position,      // Start the ray from this transform's position
 transform.forward,        // Fire it forward
 hit,                      // Save the thing we hit in the the variable we created
 100)                      // This is the length of the ray we fire

If the ray we fire hits something then we now have the RaycastHit variable hit. We can now use this to access the object.

 hit.collider.transform    // This is the transform of the object we hit. Do with this as you will!
