AS3 class for a Flash Symbol

Question

I am new to Flash, I am trying to create a class for a symbol.

I created a new Flash file, drop a DynamicText, convert this DynamicText to a Symbol called "TextBox1"

Then I created TextBox1.as in the same directory as the .fla I just created.

package
{
    import flash.display.*;

    public class TextBox1 extends MovieClip
    {

        public function TextBox1() 
        {
            trace("TextBox constructor");
        }

    }

}

I ran the Flash file but it doesn't display the message. Did I miss anything?

Answer 1

Did you associate the class with the symbol? Right click the symbol. Tick export for ActionScript and put TextBox1 in the class field.

Answer 2

You don't need to create a blank class definition to use assets. Simply type in a class you want it to be called in Class under Linkage, and make sure the bass class is flash.display.MovieClip. When you press OK, Flash will come up with a box saying it will create a default definition for you, which is great. Now you can create instances of the class.
