Weapons Range Projectile script

So i'm trying to make it so when my enemy ship is within a certain range of the Tag "Player" that it fires a projectile at the player tag, but at the moment it's just firing at any range

 var projectile:Rigidbody;
 var TorpedoSpeed:float = 0.0;
 var shotDelay:float = 3;
 var lastshot:float = Time.time;
 
 private var launchLocation:Vector3;
 launchLocation = Vector3(transform.position.x,transform.position.y,transform.position.z);
 
 function Update()
 {
     if ((Time.time - lastshot) > shotDelay) {
         TargetObj = GameObject.FindGameObjectWithTag("Player");
         lastshot = Time.time;
         var dist = Vector3.Distance(TargetObj.transform.position, TargetObj.transform.position) < 10;
         GetLaunchLocation();
         var instantiatedProjectile:Rigidbody = Instantiate(projectile,launchLocation,transform.rotation);
         instantiatedProjectile.transform.Rotate(Vector3(0,0,0));
         instantiatedProjectile.velocity = transform.forward * TorpedoSpeed;
         Physics.IgnoreCollision(instantiatedProjectile.collider,transform.root.collider);
 }
 }
 
 function GetLaunchLocation()
 {
 launchLocation = Vector3(transform.position.x,transform.position.y,transform.position.z);
 }

Also this is my first time using Unity Answers so please forgive me if i formatted my code wrong.
