actionscript 3 - Stop clock on pause button -

i have "clock" counting down time of game (from 9 seconds 0 seconds). have button pauses game, want freeze de clock , when click play, game continuos second frozen. don't have idea how this! can me please?

this.addeventlistener(event.enter_frame, updatetimer);      function updatetimer(e:event){         var t:uint = gettimer();     var dt:uint = 9000 - t;     var totseconds:uint = math.floor(dt/1000);     var minutes:uint = math.floor(totseconds/60);     var seconds:uint = math.floor(totseconds%60);     var minswithz = minutes < 10 ? "0" + minutes : minutes;     var secswithz = seconds < 10 ? "0" + seconds : seconds;     var time = minswithz + ":" + secswithz;     this.tempo_txt.text = time;  }     pausa.addeventlistener(mouseevent.mouse_up, menupause);  function menupause(e:mouseevent){     ...somegame code...     voltar.addeventlistener(mouseevent.mouse_up, play); }  function play (e:mouseevent){     ...some game code  } 

you have 2 choices @ least:

1-andre's answer;

2-my answer:

import flash.events.event;      var dt:int = 9000  var diff:number=0; var prevdiff:number=0; var currenttime:number=0;    var t:uint=0; var totseconds:int=0; var minutes:int=0; var seconds:int=0; var minswithz; var secswithz;  var running:boolean=true;  var time; this.addeventlistener(event.enter_frame, updatetimer);     function updatetimer(e:event){ if(dt<1){dt=1;menupause(null)} trace(running); totseconds= math.floor(dt/1000); minutes= math.floor(totseconds/60); seconds= math.floor(totseconds%60); minswithz = minutes < 10 ? "0" + minutes : minutes; secswithz = seconds < 10 ? "0" + seconds : seconds; time = minswithz + ":" + secswithz;  this.tempo_txt.text = time;      if(running){  t= gettimer()-diff-prevdiff; dt=5000- t;   }else{ diff=gettimer()-currenttime;   }     }  pausa.addeventlistener(mouseevent.mouse_up, menupause); voltar.addeventlistener(mouseevent.mouse_up, reset);    function menupause(e:event){ running=false; currenttime=gettimer(); prevdiff+=diff;  }  function menuplay (e:event){ running=true;  }   function reset(){  running=true;  prevdiff+=9000;    } 

a little explaination on code:
gettimer() returns miliseconds when opened app ,

you can't pause "gettimer()"

but can time game paused , subtract gettimer().
variable "diff" here.
, "currenttime" when paused game.

andre's answer more easy;
answer more accurate.

because gettimer() returns real miliseconds timer not ticking accurate.enter_frame event , setinterval same timer.

that means if want more simple code, use andre's , if want accurate timer, use mine.

and removing eventlistener (3vilguy's answer) not enough because gettimer won't pause !

i hope answer useful.
