Re: [Flashcoders] Re: swf doesn't work the same online

Hi,
You are creating your sprites inside your nav function as local variables - they are probably getting garbage collected because as soon as nav returns nsprite will cease to exist in your code and will be "reaped" by the gc at any time the Flash Player chooses after that. 


   I recommend you do something like the following which means your nav 
function returns the Sprite you create and you store it, meaning it 
won't get garbage collected.

//create an array of nname, nurl, strings (shortened for convenience.:
var nNames:Array = ["Home", "Bathroom", ...];
var nUrls:Array = ["index", "Bathroom", ....];
var positions:Array [



//loop through the arrays and create each navigation element, then 
return it...

var numLinks = nNames.length();

var nNavs:Array = new Array();
for(var i:int = 0; i < numLinks;i++) {
   var nav:Sprite = nav(nNames[i], nUrls[i], positions[i], 0x0e778a);
   nNavs.push(nav);
   //do anything else you need to do to the nav sprite here.
}

//make nav return the sprite it creates.
function nav(...):Sprite {
   //create stuff
   //...
   //Create mynav text field with a name attribute!
   mynav.name = "mynav";
   //add listeners
   //....
   return nsprite;
}

function onRolloverHandler(e:MouseEvent):void {
   var nsprite:Sprite = e.currentTarget as Sprite;
   if(nsprite && nsprite.mynav) {
      TextField(mysprite.mynav).bgcolor = 0x97f9ec;
   }
}

//Repeat for the other listener handlers.

Here's the complete code. Again, all this works fine in my swf in Flash, but when I upload the swf it breaks when I roll over "Home". The color changes and won't change back when I roll out. No other nav widget works at all.
