actionscript 3 - AS3 variables from array not updating, even when given direct "command" -

i hope you're well. i've problem not understand. variables seem update don't (i've explained further in context in code below). [i'm trying create store users can buy bosses game].

i hope can me :)

here code. not hesitate ask me further details (number total of bosses around 36).

var bossbuybtnarray:array=[campagnesbuy.boss1, campagnesbuy.boss2];  //array movieclips used button buy var pbarray:array=[campagnesbuy.pb1, campagnesbuy.pb2]; //array movieclips tells if boss owned or not var bossvar:array=[sp[59], sp[60]]; //array int variables needed save state of inventory  each(var storebtn: movieclip in bossbuybtnarray)  storebtn.addeventlistener(mouseevent.click, fnbossstorebtn); //when user click on store buttons,  function fnbossstorebtn(e: event): void {     var listelementboss: displayobject = e.target displayobject; //listeelementboss = selected boss.     var iboss: int = bossbuybtnarray.indexof(listelementboss); //get index of selected boss     if (iboss < 0) { //check if selected boss in array         listelementboss = e.currenttarget displayobject;         if (listelementboss) iboss = bossbuybtnarray.indexof(listelementboss);     }     if (iboss < 0) return;     if(pbarray[iboss].currentframe == 1){ //check if boss not owned.         if (sp[58]>999){ //check if user has enough gold.              /*the part doesn't work : */             bossvar[iboss] = 1; //modify variable (sp[59] or sp[60])             //normally update variable, let's sp[59] if boss 1 selected.              //the interface modified fnalreadyowned (see below) guess updated,             //but when trace(sp[59]), says 0, , writeobject() function saves 0. meaning             //when reload game, gold gone, boss locked again.             /*the rest works*/              sp[58] = sp[58] -1000; //substract cost of boss total gold.             gamemode.piratetxt.text = sp[58]; //update gold "inventory"             writeobject(); //save state of gold , boss ownership             fnalreadyowned(null);// updates interface         }else{             trace("not enough gold"); //if not enough gold         }     }else{         trace("already owned"); //if boss owned.     } } 

when this:

var bossvar:array=[sp[59], sp[60]]; //array int variables needed save state of inventory 

you take variables sp array , put them in bossvar array. int variables copied in case.

that means changing either sp[59] or bossvar[0] won't change other.

example code:

var a:array = [1, 2]; var b:array = [a[0], 5]; a[0] = 42; trace("a[0] =" + a[0]); trace("b[0] =" + b[0]); 

you circumvent storing objects example.
