actionscript 3 - Flash Programming Local To Global problem -

i've got weird problem , cant figure out. i'm using localtoglobal coordinates character , hittestpoint on level clip. works fine in flash player 10.1. r52

but open exact same .swf on other machine running flash player 10.0 r22, , hittesting doesnt work. tried everything, tracing parents etc.

the setup:

main class, in main class add game class(sprite). in game class add level class(sprite) , character class(sprite)

the 'camera' follows character, , game class moved arround.

so

main (static x & y)> game (dynamic x & y)> level(static x & y) & character (dynamic x & y) code:

    private function checklanded():boolean     {//this code runs on character class, 'this' = character         var localpoint:point = new point(this.x, this.y + this.myheight / 2 + 1);         var globalpoint:point = parent.localtoglobal(localpoint)          if (settings.levelground.hittestpoint(globalpoint.x,globalpoint.y,true) || settings.levelplatforms.hittestpoint(globalpoint.x,globalpoint.y,true))         {             return true;         }         return false;     } 

so code runs in flash player 10.1 not in 10.0 10.0, instead of using parent.globaltolocal, tried parent.parent.globaltolocal work in 10.0 , not in 10.1.

how can make sure code run in flash players.

**edit- fixed it, moved main class arround somehow disturbed flash coordinate system. tryed moving game class arround , seem work. still wondering why moving main class arround doesnt work..

please me,

thanks in advance,

this way know coordinates of display object in reference stage

public function getdisplayobjectsrootcoord(target:displayobject):point{     var coords:point = target.localtoglobal(new point());     return coords; } 

or see if mouse on item...

var target:movieclip; var stage:stage;// make sure have reference var mouseoverpanel:boolean = target.hittestpoint(stage.mousex,stage.mousey,true);
