Accessing variables

[0gani]

how do I access a variable that was created in a function? For example

function create()

{

  var myvariable:string='hello world';

}

trace myvariable

does anyone have a solution for this?

You don't. Variables created in function are local to that function scope and cannot be accessed outside of that.

Your options are: use a class variable (where your function is a method of that class and that variable is accessible from an instance of that class), pass an accessible object into the function where the variable is a property of that object, or have the function return the value you wish to obtain.

I am sorry. I just do not understand that. Could someone give me a simple example.

public var myvariable:string='hello world';

function create(){
  myvariable="modified by create"; //modifies the variable
}

trace(myvariable); //read it outside the function too
