Modifica script per preloader

[zeropunto]

Ciao, ho trovato questo script per precaricare i filmati, importato nel primo fotogramma e poi richiamato,
mi precarica il filmato stesso.

Ora invece vorrei adattarlo per fargli caricare i file che voglio io nel mc che voglio io...
come posso fare?

/*
Parameters: 
xDistance: x position of loaderbar 
yDistance: y position of loaderbar 
barHeight: height of the loaderbar 
barColor: hexadecimal color value for the loaderbar fill 
frameName: name of the frame to go when movie is loaded 
Example (put this script in the first frame of your movie): 

stop();
var myLoader:FlashscriptLoader = new FlashscriptLoader(x,y,height,color,"framename");
