I've got some code for a Flash Panorama tool that I cannot figure out how to change. The problem is that it loads .swf files and movieClips using the _root method. I've figured out how to dump my pano .swf into an empty movieClip in my project, but this still means that once you import your panorama master .swf into a larger Flash project, that master .swf clip never goes away after you call it up.

Is there a way to replace all of the _root load instances in the script with something that you can control? Here's the code:

-------------------------

var radar_offset:Number=0;
var currentid:Number=0;
var topid:Number=1;
var hotspots:Array=new Array;

// Create container movieclip
var vr:MovieClip = _root.createEmptyMovieClip("vr", 1);
// prevent access to "real" root
vr._lockroot=true;

function clearHotspots() {
var mc:MovieClip;
var i:Number;
for (i=0;i<hotspots.length;i++) {
mc=hotspots[i];
mc.removeMovieClip();
}
hotspots=new Array();
}

function loadPanorama(id:Number) {
// Create a Movieclip loader
var myLoader = new MovieClipLoader();
var myListener = new Object();

// remove old Hotspots
clearHotspots();

myListener.onLoadStart = function () {
var filename:String;
// Set the dimentions and position of the pano
vr.window_width=500;
vr.window_height=398;
vr.window_x=364;
vr.window_y=0;
// change autorotation
vr.autorotate=0.5;
vr.autorotate_delay=20;

// add a preview bar...
var my_fmt:TextFormat = new TextFormat();
my_fmt.bold = true;
my_fmt.font = "Arial";
my_fmt.size = 12;
my_fmt.color = 0xffffff;
_root.createTextField("pretxt",10,170,40,200,20);
_root.pretxt.setNewTextFormat(my_fmt);
_root.pretxt.selectable = false;
_root.pretxt.text = "Loading...";
_root.createEmptyMovieClip("prebar",21);
};

myListener.onLoadProgress = function(target_mc:MovieClip, loadedBytes:Number, totalBytes:Number) {
// update progress bar
var x1:Number,x2:Number,y1:Number,y2:Number;
_root.pretxt.text = "Loading... " + Math.floor(100*loadedBytes/totalBytes) + " %";
_root.prebar.clear();
_root.prebar.beginFill(0x0000FF, 30);
_root.prebar.lineStyle(2, 0x000080, 100);

x1=_root.pretxt._x;
x2=x1 + 180 * loadedBytes/totalBytes;
y1=_root.pretxt._y+20;
y2=y1+10;

_root.prebar.moveTo(x1, y1);
_root.prebar.lineTo(x2, y1);
_root.prebar.lineTo(x2, y2);
_root.prebar.lineTo(x1, y2);
_root.prebar.lineTo(x1, y1);
_root.prebar.endFill();

};

myListener.onLoadComplete = function () {
// remove progress bar
_root.pretxt.removeTextField();
_root.prebar.removeMovieClip();
};

myListener.onLoadInit = function () {
setupPanorama(currentid);
// Add another hotspot to position pan 0, tilt -90 (nadir) without rollover effect
var hs_p2q:MovieClip=_root.attachMovie("pano2qtvr_lib" ,"hs_textmc2",10200);
hs_p2q.onRelease=function() {
_root.getURL('http://www.pano2qtvr.com','_blank');
}
vr.pano.addHotspot('p2q',0,-90,hs_p2q);
// add hotspots to a list to clear them
hotspots.push(hs_p2q);
compass.fov._visible=true;
};

// add the Listener
myLoader.addListener(myListener);

// set the parameters for the different panoramas
if (id==1) {
filename="/support/StateFarm-Office.swf";
radar_offset=0;
compass._x=map._x+map.bt1._x;
compass._y=map._y+map.bt1._y;
}
if (id==2) {
filename="/support/StateFarm-Welcome.swf";
radar_offset=180;
compass._x=map._x+map.bt2._x;
compass._y=map._y+map.bt2._y;
}

// remove the radar during loading
compass.fov._xscale=0;
compass.fov._yscale=0;
compass.fov._visible=false;

// ... and finally load the pano!
myLoader.loadClip(filename, vr);
currentid=id;

}





// add the map
var map:MovieClip=_root.attachMovie("map","map",20005, {_x:230,_y:0});

// connect the buttons in the map
map.bt1.onPress=function () {
loadPanorama(1);
}
map.bt2.onPress=function () {
loadPanorama(2);
}


// ... and the rader is even higher...
var compass:MovieClip=_root.attachMovie("compass_lib", "compass",20010,{_x:60,_y:200,_alpha:50});

compass.fov._xscale=0;
compass.fov._yscale=0;
compass._visible=true;
compass.fov._visible=false;

// update the shape of the rader on each frame
_root.onEnterFrame=function() {
compass.fov._rotation=-(vr.pano.getPan()+radar_offset);
compass.fov._xscale=100*Math.tan(vr.pano.getFov()* Math.PI/360);
compass.fov._yscale=100*Math.cos(vr.pano.getTilt() *Math.PI/180);
}

// load the pavilion pano first
loadPanorama(2);
