Buff Follow

Hello Unity3D.I have a question about making an object follow a player.How can i make it that i can make a object follow a character/player?For example.I have a buff for my character that it uses which is a sword and i want it that whenever my character moves the sword follows the character at the exact speed time.If anyone knows how i can do this.Can you please tell me how?I have been searching and i can't find it.

Script if anyone needs it

 var target : Transform;
 var moveSpeed = 100;
 var rotationSpeed = 0;
 var myTransform : Transform;
  
 function Awake() {
         myTransform = transform;
 }
  
 function Start() {
  
         target = GameObject.FindWithTag("Player").transform;
 }
  
 function Update () {
    
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
     Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
     myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
 }
