How do I make an object move towards another object and then keep that direction

Question

I want to instantiate a Projectile and making it move towards Enemy but not change direction (so if enemy is straight above the object that instantiates it at frame its instantiated the Projectile will start moving straight above the player toward the enemy, but if the enemy moves the Projectile will not change direction). Effectively I want a MoveToward but it doesn't change direction and keeps going past the area where it was initially shot toward (basically just keeps flying until its destroyed, which I might do with a timer if it doesn't hit anything in time)

EDIT: Also I want so I can choose at which speed the object flies, maybe with a serialized float?

Assuming the script is on the player, you can get the direction from player to target in this way:

 Vector3 direction = (target.transform.position - transform.position).normalized;

You can get a serialized field using [serializedfield] float speed;

Now you can move the projectile in the direction where the enemy was to start with, not where the enemy has moved to. how you move depends on whether you are using transform.Translate or Physics to move the projectile. If you're using transform.Translate, you would code something like:

 void Update()
 {
    Vector3 distance = direction * speed * Time.DeltaTime;
    projectile.transform.Translate(distance);
 }

Did I do something wrong, and if not do you know how to fix the error? Also the MoveToward should be in Update() right (just double checking)? I somewhat understand the error but I don't want a max distance on the object alt text

I've added a bit to my original posting to clarify. You don't need MoveToward at all. The thing about MoveToward is that it will stop when it gets to its destination, which is probably not what you want your projectile to do. It should go on until it hits something or until you destroy it.

Your answer works exactly like I want it, although took me a bit to make it work because I messed up some stuff and didn't realize. Thank you! Also may I know what normalize does? I read it a bit but didn't really understand what it's for.
