        x += vx
        y += vy
    public function onKeyDown(event:KeyboardEvent){
        if (event.keyCode == Keyboard.LEFT){
            gotoAndStop(2)
            vx = -5
                if (event.keyCode == Keyboard.RIGHT){
                    gotoAndStop(1)
                                vx = 5
        if (event.keyCode == Keyboard.DOWN){
            vy = +5
            gotoAndStop(6)
if (event.keyCode == Keyboard.UP){
            vy = -5
public function onKeyUp(event:KeyboardEvent){
            if (event.keyCode == Keyboard.LEFT ||event.keyCode == Keyboard.RIGHT ){
                vx= 0;
if (event.keyCode == Keyboard.UP ||event.keyCode == Keyboard.DOWN ){
                vy= 0;
THE DOCUMENT CLASS (Main)
package  {
    import flash.system.System;
import flash.system.fscommand;

    import flash.events.Event;
    import flash.events.MouseEvent;
    import flash.display.Stage;
    public class Main extends MovieClip {
        var mainmap1:MAINMAP1 = new MAINMAP1;
        public function Main() {
            addChild(mainmap1);
i hope you guys can help because i tried to move the hero but i couldn.t the whole problem from the HERO class (i guess)
thank you

Answer 1

I don't see the HERO class in any code you show, and if there is no instance of it on the stage, then you have no HERO object to move.  Nothing is creating one and there is none to begin with otherwise.
What you might try to help you understand and get this working is to create a new fla file and create a movieclip on the stage and assign it the class name HERO via its linkage.  Then, with the HERO class file in the same folder as that fla, run the fla.  YOu should see the HERO object moving with your keyboard controls.
Then, remove that object from the stage and in the first frame use... var hero:HERO = new HERO();  addChild(hero);   ... and you should see the same result of being able to move a dynamically created instance of HERO around with the keyboard.
Then see how to work this into the other file you are wroking on.
