Correct answer Elliot Mebane

To change your original code the least you could replace the sortio function with this. It assigns the new random number to the resultado variable then assigns resultado to the text field.

function sorteio():Number

{

  resultado = Math.round(Math.random() *500);

  sorteio_txt.text = resultado.toString();

  return resultado;

}

kglad's solution is also great and works.

In your example you want a string version of the random number. A good design would keep your resultado variable saved as a number and convert it to a string only when you need to display it in a text field. In this version you have resultado saved as a number variable and each method does its thing. Everything is a little more decoupled.

var resultado:Number;

 

sorteio();

displayResultado();

my_btn.addEventListener(MouseEvent.CLICK, onClick);

 

function sorteio():void

{

  resultado = Math.round(Math.random() *500);

}

function displayResultado():void

{

  sorteio_txt.text = resultado.toString();

}

function onClick(e:MouseEvent):void

{

  sorteio();

  displayResultado();

}

use:

function sorteio():String

{

return Math.round(Math.random() *500).toString();

}

sorteio_txt.text = sorteio();

my_btn.addEventListener(MouseEvent.CLICK, onClick);

function onClick(e:MouseEvent):void

{

  sorteio_txt.text = sorteio();

}
