script on monster checks if bool on attacking player = true?

I'm creating a melee system that works but I need to redo it so I can use it online if it ever gets there. What I think I need to do is, on the monster, on triggerenter, get the player thats doing the attack and check a variable on him. Say, isAttacking = true. Then if its true do the rest. I'm wondering is this possible? Heres my example code atm that i'm trying to convert to that idea.

---Attached to enemy---

static var swordReady : boolean = false;

function Start () {

}

function Update () {

}

 function OnTriggerEnter (col : Collider)
 
 {
     if(swordReady == true)
     {
     if(col.tag == "Weapon")
     {
     EnemyLogic.Enemy_Health -= 25;
     print(EnemyLogic.Enemy_Health);
     swordReady = false;
     }
 }

}

 ---Attached to Player---

 #pragma strict
 function Start () {
  
 }
  
 function Update ()
 {
     if (Input.GetButtonDown("Fire1"))
     {
         Enemy_Attacked.swordReady = true;
         animation.Play("Attack");
         animation["Attack"].wrapMode = WrapMode.Once;
     }
 }
