accessing variables

yeah good one ... I think that if the imported class is an extension of Display Object, then yeah. If not, you'll have to pass in a reference to the stage. Ideally this would be through the constructor. lets just make a worst case scenario here:

package
{
public class Basic
{
private var global;

public function Basic(theStage:Stage)
{
global = theStage.getChildAt(0);
// ok so now everything in this class can use the global property to get at these global variables
}

public function method1()
{
trace(global.count);
++global.count;
trace(global.count);
}
}
}


Alright now lets say we're at some timeline somewhere. I just instatiate Basic and pass in the stage. Like this:

var bsc;
bsc = new Basic(this.stage); // the "this" is optional because it is implied i just have it shown for clarity
bsc.method1();


And that should do it. If Basic were to be an extension of say, the Sprite class, anywhere in the class definition you could say "this.stage.getChildAt(0)" and it will work. However if you were to reference ".stage" in a display object class definition before it was added to the display list, it might be "undefined." Hope thats what you were after.

Yep. Then you can read it, and write to it, from anywhere.
