How do I make an instance of a class global???

Question

Hi to all! I'm a newbie to OOP, coming from C. I just made my first class, but cannot figure out how to make an instance of it globally available. Here is a much simplified version of what I am trying to do:`

 class Person{var name : String;}
 static var person1 : Person;
 person1.name = "Luke";
 static var person2 : Person;
 static person2.name = "Greg";

I know static doesn't work here. But I so wish it would! I need to list persons in a Person.js script, and access them from another script. Are singletons the answer? Help very much appreciated! G

As long as a class is public, it's global. If you have this in one script:

 class Person {  // or "public class Person"; public is default in Unityscript
     var name : String;
 }

Then in any other script you can do

 var person1 = new Person();

It's unlikely you want to make the variable static. That means there can only be one instance of it. You also probably want to make a constructor for the class, so you can do

 var person1 = new Person("Luke");

If you're talking about the variable itself being global, the same thing applies. As long as it's public, it can be accessed from another script, usually by using a reference to the other game object in combination with GetComponent. See Accessing Other Game Objects in the docs.
