How to pass a class without it being a pointer/reference?

Question

 function GiveEntityGun(ent : Entity, gunItemClass : ItemClass)
 {
     gunItemClass = new ItemClass();
     gunItemClass.exist = true;
     // ... more stuff happens ...
 }

gunItemClass is not meant to stay as a reference. I need it to keep its values, but become its own instance. Unfortunately, this code wipes all its values.

Can anyone please help me? I haven't been able to find the answer online yet.

You need to use a 'copy constructor.'

 class ItemClass {
   var myVar : float;

   function ItemClass() { myVar = 1; };
 
   function ItemClass( other : ItemClass ) {
     myVar = other.myVar;
   }
 }

Then later you can use var gic : ItemClass = new ItemClass( gunitemClass );
