Why am I losing my array?
I have a problem with accessing an array from a function within a function in a custom class...I have a function that uses the array booths[]...the function calls a zoom function which runs on a tween...then there is a function for when the tween finishes...however...after the zoom completes tracing the booths[] array still returns the correct values...once I enter the tweenFinished function...the booths[] array returns undefined for all values...I have 7 traces strewn threw my code here and it shows exactly when the problem occurs...can anyone help me solve this?
code:
function listClick(boothArr:Array)
{
var lowX:Number = booths[boothArr[0]].xValue;
var lowY:Number = booths[boothArr[0]].yValue;
var tarX:Number;
var tarY:Number;
var highX:Number = booths[boothArr[0]].xValue + booths[boothArr[0]]._width;
var highY:Number = booths[boothArr[0]].yValue + booths[boothArr[0]]._height;
var myPoint:Object = {x:0, y:0};
var myPoint2:Object = {x:0, y:0};
var centerWinX:Number;
var centerWinY:Number;
var tempX:Number;
var tempY:Number;
var boothX:Number;
var boothY:Number;
var boothOffsetX:Number;
var boothOffsetY:Number;
var moveX:Number;
var moveY:Number;
var zoomTo:Number;
for(var i=0; i<boothArr.length; i++)
{
var booth:Number = boothArr[i];
var trans5:Transform = new Transform(booths[booth]);
var trans6:Transform = new Transform(miniBooths[booth]);
var myColor:ColorTransform = new ColorTransform(1, 1, 1, 1, 0, 255, -255, 50);
trans5.colorTransform = trans6.colorTransform = myColor;
booths[booth].boothLight = true;
trace("1 "+ booths[0].xValue+ " "+booths[0].yValue);
if(boothArr.length > 1)
{
if(booths[booth].xValue<lowX)
{
lowX = booths[booth].xValue;
}
if(booths[booth].yValue<lowY)
{
lowY = booths[booth].yValue;
}
if((booths[booth].xValue + booths[booth]._width)>highX)
{
highX = booths[booth].xValue + booths[booth]._width;
}
if((booths[booth].yValue + booths[booth]._height)>highY)
{
highY = booths[booth].yValue + booths[booth]._height;
}
}
else
{
lowX = highX = booths[booth].xValue;
lowY = highY = booths[booth].yValue;
}
}
if(lowX == highX && lowY == highY)
{
tempX = lowX;
tempY = lowY;
boothOffsetX = booths[booth]._width/2;

}
else

var tempVar:Number;
if((highX-lowX) > (highY-lowY))
{

zoomTo = (_root.hitAreaMain._width*70)/zoomArea;
}
else
{
zoomArea = highY-lowY;
zoomTo = (_root.hitAreaMain._height*70)/zoomArea;
}
}
else
{
zoomTo = (_root.hitAreaMain._width*10)/booths[boothArr[0]].zoomScale;
}
_root.hitAreaMain.localToGlobal(myPoint2);
centerWinX = myPoint2.x + (_root.hitAreaMain._width/2);
centerWinY = myPoint2.y + (_root.hitAreaMain._height/2);
trace("2 "+ booths[0].xValue+ " "+booths[0].yValue);
_root.scaleTo(zoomTo);
trace("3 "+ booths[0].xValue+ " "+booths[0].yValue);
//trace(zoomTo);
_root.tween_handler.onMotionFinished = function()
{
trace("4 "+ booths[0].xValue+ " "+booths[0].yValue);
//trace(zoomTo);
_root.container.localToGlobal(myPoint);

moveX = (centerWinX - boothX);
moveY = (centerWinY - boothY);
trace("5 "+ booths[0].xValue+ " "+booths[0].yValue);
_root.checkBounds(moveX, moveY, 1, 0);
trace("6 "+ booths[0].xValue+ " "+booths[0].yValue);
_root.tween_handler.onMotionFinished = function()
{
trace("7 "+ booths[0].xValue+ " "+booths[0].yValue);
_root.container.localToGlobal(myPoint);
for(var j=0; j<boothArr.length; j++)
{
//var b:Number = boothArr[j];
//trace("2 "+tAx[j]+ " " +tAy[j]);
//tarX = tAx[j]*(zoomTo/100)+myPoint.x;
//tarY = tAy[j]*(zoomTo/100)+myPoint.y;
//_root.placeTarget(tarX, tarY, j);
// _root.placeTarget((boothX+_root.actualMoveX-(boothOffsetX*(zoomTo/100))), (boothY+_root.actualMoveY-(boothOffsetY*(zoomTo/100))), i);
}
_root.numTargets = boothArr.length;
}
}
}
trace output:
1 2122.5 1110
2 2122.5 1110
3 2122.5 1110
4 undefined undefined
5 undefined undefined
6 undefined undefined
7 undefined undefined
any ideas?

Show in the dark as I did this quickly:
PHP Code:

booths[booth].boothLight=true;
trace("1 " + booths[0].xValue + " " + booths[0].yValue);
if (boothArr.length > 1) {
if (booths[booth].xValue < lowX) {
lowX=booths[booth].xValue;

I actually tried what you had suggested prior to posting my original post...however I failed to include one key piece of information...this function is within a custom class...so the _global command cannot be applied to an element in the class...
-
Ok, thanks for letting me know 
What does this return:
PHP Code:
_root.tween_handler.onMotionFinished=function(booths)// Pass the variable throug function
{
trace(booths);// Trace this to see if it returns an object, if not then we have to look at the scope of the variable.

Ah yeah thats right, sorry long day. How and where are you declaring the booths variable in your class?
-
to counter the scope problem in the tween handler why not try to assign to a var on _root?
PHP Code:
for(var i=0; i<boothArr.length; i++) {
_root.traceBooth = booths[0].xValue+ " "+booths[0].yValue;
trace("1 "+ _root.traceBooth);
//other code
}
later: trace("4 "+ _root.traceBooth); etc.
