actionscript 3 - As3 - Script Error on Arrays -

please inspect me coding:

function createrandomlist():void {     var newlist:array = [0,1,2];     var curlist:array = item[selectedlevel - 1] //selectedlevel = 1;     var normal:int = curlist[0];     var tempboo1:boolean = false;     var tempboo2:boolean = false;     var tempboo3:boolean = false;     while (curlist[0] + curlist[1] + curlist[2] > 0)     {         if (number(curlist[0]) == 0 && tempboo1 == false)         {             newlist.splice(newlist.indexof(0), 1);             tempboo1 = true;         }         if (number(curlist[1]) == 0 && tempboo2 == false)         {             newlist.splice(newlist.indexof(1), 1);             tempboo2 = true;         }         if (number(curlist[2]) == 0 && tempboo3 == false)         {             newlist.splice(newlist.indexof(2), 1);             tempboo3 = true;         }     var temp:int = math.floor(math.random()*(newlist.length));     curlist[temp] -=  1;     generatedlist.push(number(newlist[temp]));         trace(item);     }      while (normal > 0)     {         var temp2:int = math.floor(math.random() * 3) + 1;         generatednormal.push(number(temp2));         normal--;     } } 

my item [[5,0,0],[10,0,0]]; after became [[0,0,0],[0,0,0]];

i want duplicate array item new variable curlist.

every time traces, returning item[0][0] decreasing 1, want use curlist temp array calculate new random array based on item[0].

ouput:

4,0,0,10,0,0 3,0,0,10,0,0 2,0,0,10,0,0 1,0,0,10,0,0 0,0,0,10,0,0 

is there links between them, or problem? please help! if need more infoemation, please comment me!

you can clone arrays if want create new reference.

function clone( source:object ):*  {      var myba:bytearray = new bytearray();      myba.writeobject( source );      myba.position = 0;      return( myba.readobject() );  }   var a:array = [[0,0],[1,1]]; var b:array = clone(a);  b[0] = [2,2];  trace(a) trace(b) 

output

0,0,1,1 2,2,1,1 

it works object, not arrays. more infos here : as3 - clone object
