How to set a variable equal to another variable in another gameobject?

Question

What I'm trying to do is a build a system where the player can see a weapon on the ground, it clones a new weapon and carries all the set variables over to that clone (ammo etc), pick up the clone, and that should replace the other weapon they're already holding.

My other game object is called Weapon Controller, and that has the script called weaponHandler, which has all the code used to hold any weapon it's given and switch between the two of them. weaponHandler has to two variables, one for each weapon.

Any help I can get I'd appreciate :')

 #pragma strict
 
 var weapon : GameObject; //any weapon can be used here
 var currentClip : float;
 var currentAmmo : float;
 var currentWeapon : Component;
 
 function Start ()
 {
 
 }
 
 function OnTriggerEnter (other : Collider) 
 {
 
     print("Item is in range");
     var weaponClone : GameObject = Instantiate (weapon); //clone the weapon
     currentWeapon = gameObject.GetComponent(WeaponHandler); //check what weapon is in the weapon1 variable
     currentWeapon.weapon1 = weaponClone; //change that current weapon to our new cloned weapon
     //var currentSelected = currentWeapon.GetComponent(WeaponHandler).weapon1;
     //currentSelected = weapon;
     
     
 }

If you're asking the almost-question in the title:

someGameObject.GetComponent(TypeName).variable = aValue;

or

aVariable = someGameObject.GetComponent(TypeName).variable;

GetComponent is "slow", so if you're going to use it a lot it's better to cache the value as a reference:

var typeName : TypeName = someGameObject.GetComponent(TypeName);

typeName.variable = value;

Thanks I tried that out but had no success, I ended up trying something else which I thought would work.

Problem is it now says "An instance of type "WeaponHandler" is required to access non static member 'weapon1'". I changed the weapon1 variable to static, compiled, but of course changes everything, any idea for a solution around this? I'm not sure how to set the appropriate access between it all.

 #pragma strict
 
 var weapon : GameObject;
 var currentClip : float;
 var currentAmmo : float;
 var currentWeapon : GameObject;
 
 function Start ()
 {
 
 }
 
 function OnTriggerEnter (other : Collider) 
 {
     var weaponClone : GameObject = Instantiate (weapon); //clone the weapon
     print("Item is in range");
     WeaponHandler.weapon1 = weaponClone;
     WeaponHandler.weapon1 = currentWeapon;

Besides it being bad form to submit answers to your own questions, it's not much of an answer if it doesn't work, is it?

I'm just trying to figure it out, it wasn't meant as an answer, just maybe progress that I could use a hand with.

That's cool...but questions with more than one answer tend to get ignored because two is usually sufficient.

Yea that makes sense, I'm still new the forums and the layout is kinda weird to me. I guess I'll just learn my way around. Thanks for the tip though, I won't make that mistake again :')
