package  { import flash.display.movieclip; import flash.events.event; import flash.events.mouseevent; import flash.events.timerevent; import flash.utils.timer; import flash.ui.mouse; import flash.media.sound; import flash.media.soundchannel; import flash.text.textformat; import flash.text.textfield; import flash.display.loader; import flash.net.urlrequest; import flash.net.urlloader; import flash.system.loadercontext;  public class main extends movieclip {  public var gametime:int; public var levelduration:int;      public var crosshair:crosshair_mc; static var score:number;  var enemyshiptimer:timer; var enemyshiptimermed:timer; var enemyshiptimersmall:timer; var menu:menumain = new menumain;  static var scoreheader:textfield = new textfield(); static var scoretext:textfield = new textfield(); static var timeheader:textfield = new textfield(); static var timetext:textfield = new textfield();  public function main() {     levelduration = 30;     gametime = levelduration;     var gametimer:timer = new timer(1000,levelduration);     gametimer.addeventlistener(timerevent.timer, updatetime);     gametimer.addeventlistener(timerevent.timer_complete, timeexpired)     gametimer.start();       scoreheader = new textfield();     scoreheader.x = 5;     scoreheader.text = string("score: ");     addchild(scoreheader);      scoretext = new textfield();     scoretext.x = 75;     scoretext.y = 0;     scoretext.text = string(0);     addchild(scoretext);      timeheader = new textfield();     timeheader.x = 490;     timeheader.y = 0;     timeheader.text = string("time: ");     addchild(timeheader);      timetext = new textfield();     timetext.x = 550;     timetext.y = 0;     timetext.text = gametime.tostring();     addchild(timetext);      var scoreformat = new textformat("arial rounded mt bold", 20, 0xffffff);     scoreheader.settextformat(scoreformat);     scoretext.settextformat(scoreformat);     timeheader.settextformat(scoreformat);     timetext.settextformat(scoreformat);      enemyshiptimer = new timer(2000);     enemyshiptimer.addeventlistener("timer", sendenemy);     enemyshiptimer.start();      enemyshiptimermed = new timer(2500);     enemyshiptimermed.addeventlistener("timer", sendenemymed);     enemyshiptimermed.start();      enemyshiptimersmall = new timer(2750);     enemyshiptimersmall.addeventlistener("timer", sendenemysmall);     enemyshiptimersmall.start();      crosshair = new crosshair_mc();     addchild(crosshair);      crosshair.mouseenabled = crosshair.mousechildren = false;      mouse.hide();      stage.addeventlistener(event.enter_frame, movecursor);     resetscore();     showmenu(); }  function showmenu() {     stage.addchild(menu);     mouse.show();     enemyshiptimer.stop();     enemyshiptimermed.stop();     enemyshiptimersmall.stop(); }  function sendenemy(e:event) {     var enemy = new enemyship();     stage.addchild(enemy);     stage.addchild(crosshair); }  function sendenemymed(e:event) {     var enemymed = new enemyshipmed();     stage.addchild(enemymed);     stage.addchild(crosshair); }  function sendenemysmall(e:event) {     var enemysmall = new enemyshipsmall();     stage.addchild(enemysmall);     stage.addchild(crosshair); }  static function updatescore(points) {     score += points;     scoretext.text = string(score);     var scoreformat = new textformat("arial rounded mt bold", 20, 0xffffff);     scoreheader.settextformat(scoreformat);     scoretext.settextformat(scoreformat); }  static function resetscore() {     score = 0;     scoretext.text = string(score); }  function updatetime(e:timerevent):void {     trace(gametime);     // class variable tracking each second,      gametime--;     //update user interface needed     var scoreformat = new textformat("arial rounded mt bold", 20, 0xffffff);     timetext.defaulttextformat = scoreformat;     timetext.text = string(gametime); }  function timeexpired(e:timerevent):void {     var gametimer:timer = e.target timer;     gametimer.removeeventlistener(timerevent.timer, updatetime)     gametimer.removeeventlistener(timerevent.timer, timeexpired)     // whatever need game on }  function movecursor(event:event)  {   crosshair.x=mousex;   crosshair.y=mousey; } } } 

i have been trying figure out of day don't have lot of experience actionscript.

create 2 containers (sprites or movieclips), add 1 want in first, , 1 want in front second. now, add menu front 1 , evrything else one.
