Flash / Flex / ActionScript/Development/trace

The default for most objects is to display the word "object" followed by their class name.

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        trace(new Sprite()); // Displays: [object Sprite]
    }
  }
}

trace() method will automatically call toString() on each parameter passed in.

 

package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var now: Date = new Date();
        trace("Today"s date is "+ now.toString ());
        trace(new Date()); // Displays: Sat Nov 18 22:37:22 GMT-0500 2006
    }
  }
}

trace out a message: the value of a variable, or just about any other data using trace

 
package {
    import flash.display.Sprite;
    
    public class Main extends Sprite {
        public function Main(  ) {
            var userName:String = "Bill Jack";
            trace("My name is " + userName + ".");
        }
    }
}
