Okay I have a problem here that is probably basic for most of you. I need to know how to reference variables in other classes. I have been avoiding this by referencing variables from the Main class, where they are created. But at this point I would like to be able to have the option and it would make me a better programmer.

Say I create a movieclip in the **Main.as**

```auto

public var Enemy_mc:Enemy = new Enemy();
addChild(Enemy_mc);

```

Now in another .as file, **Background.as** I want to tell the Enemy to move to the right:

```auto

Enemy_mc.x += 5;

```

How do I do that^ without creating a variable in Main.as and having it check Background.as for variable updates?

Can I do something like “ **Main.Enemy\_mc += 5;** ” like I can do in Main.as to variables that I have created in Main in other classes?

Thanks!
