empty._x = 0;
empty._y = 0;
my_mc = new MovieClipLoader();
preload = new Object();
my_mc.addListener(preload);
preload.onLoadStart = function(targetMC) {
trace("started loading "+targetMC);
container._alpha = 0;
bar._visible = true;
border._visible = true;
pText._visible = true;
};
preload.onLoadProgress = function(targetMC, lBytes, tBytes) {
bar._width = (lBytes/tBytes)*100;
pText.text = “% “+Math.round((lBytes/tBytes)*100);
};
preload.onLoadComplete = function(targetMC) {
container.fadeIn();
border._visible = false;
bar._visible = false;
dText._visible = false;
trace(targetMC+” finished”);
};
//default image
