How to call function from another script ?

Question

Hello

i have a player script with damage simulation :

 private var ennemy : Ennemy ;
 
 function Update ()
 {
 if(Input.GetKeyUp(KeyCode.R))
 {
 ennemy = GameObject.Find("Ennemy").GetComponent(Ennemy) ;
 ennemy.ApplyDamage = 10 ;
 }

i have a ennemy script with life,armor,and function apply damage :

 var lifeEnnemy : int ;
 var armorEnnemy : int ;
 
 function ApplyDamage (damage : int){
 
    if(armorEnnemy <= 0)
    {
    lifeEnnemy -= damage ;
    }
 
    else if(armorEnnemy < damage )
    {
       var diff : int ;
       diff = damage - armorEnnemy ;
       armorEnnemy -= armorEnnemy ;
       lifeEnnemy -= diff ;
    }
    else
    {
    armorEnnemy -= damage ;
    }
    }

But i want creat a new script : "global" with lifeEnnemy and armorEnnemy and function applydamage.And modify my ennemy script in :

 private var ennemy : GlobalVar ;
 
 function Start ()
 {
 ennemy = GameObject.Find("Player").GetComponent(GlobalVar) ; 
 ennemy.lifeEnnemy = 50 ;
 
 ennemy = GameObject.Find("Player").GetComponent(GlobalVar) ; 
 ennemy.armorEnnemy = 50 ;
 }

+ my function apply damage

So i could make diferent ennemy with different life and armor.

i know how to call a variable with get component but i don't know how call a function ?

Hope it s clear ?

Thank s !

I could be mistaken but i believe at the beginning you would do something like the following:

 //if the script with applydmage is called ScriptWithDamage.cs
 private ScriptWithDamage damageScript;
 
 //in awake
 void Awake()
 {
 damagescript = GetComponent<ScriptWithDamage>();
 }
 
 //Then when you want to call it
 damagescript.ApplyDamage(10);
