var keysDown:Array=[];
stage.focus=stage;
stage.addEventListener(KeyboardEvent.KEY_DOWN,addKey);
stage.addEventListener(KeyboardEvent.KEY_UP,removeKey);
function addKey(event:KeyboardEvent):void {
    keysDown[event.keyCode]=true;
function removeKey(event:KeyboardEvent):void {
    keysDown[event.keyCode]=false;
var timer:Timer=new Timer(25);
timer.addEventListener(TimerEvent.TIMER, tick);
function tick(event:Event):void {
    if (keysDown[Keyboard.RIGHT]) {
        trace("right key is down!");
//create horizontal acceleration
var xspeed:Number=0;
var accelleration:Number=2;
var friction:Number=0.5;
var maxspeed:Number=15;
var backmaxspeed:Number=-15;
addEventListener(Event.ENTER_FRAME, accelerate);
function accelerate(e:Event):void {
    character_mc.x+=xspeed;
if(character_mc.x>stage.stageWidth-100){
// tween stage mc to left
} else if(character_mc.x<100){
// tween stage mc to right
    if ((keysDown[Keyboard.RIGHT])&&(xspeed < maxspeed)) {
        xspeed+=accelleration;
    if ((keysDown[Keyboard.LEFT])&&(xspeed > backmaxspeed)) {
        xspeed-=accelleration;
    if (xspeed>0) {
        xspeed-=friction;
    if (xspeed<0) {
        xspeed+=friction;
//create gravity for jumping
var vy:Number=0;
var jumped:Boolean=false;
var gv:Number=1.5;
addEventListener(Event.ENTER_FRAME,ctrl_hero);
stage.addEventListener(KeyboardEvent.KEY_UP, jump);
function ctrl_hero(e:Event) {
    if ((keysDown[Keyboard.UP])&&(character_mc.y == character_mc.y)) {
        jumped=true;
         vy+=gv;
     if (! stage_mc.hitTestPoint(character_mc.x,character_mc.y,true)) {
          character_mc.y+=vy;
     if (vy>10) {
         vy=10;
    for (var i:int = 0; i<10; i++) {
        if (stage_mc.hitTestPoint(character_mc.x,character_mc.y,true)) {
            character_mc.y--;
