An example of an ActionScript 3.0 class that can calculate a user's download speed, which can then be used to determine the total time left for a specific file to be downloaded.
NOTE:
Currently has a runtime error of #2044, which can be fixed but I don't feel like debugging it right now. The class included in this project can be easily used in any project since all the functions are static.
Here is the current code in the Example File.fla, which if modified to fix the #2044 error, then it should work perfectly fine with any other project you may need it for:
var url:String = "FILE URL";
var startTime:Number = 0;
function beginDownload(e:MouseEvent):void
{
// First attempted with URLLoader but still getting error #2044 for some reason..
// Should work properly when used to perform the initial SWF load with the this.loaderInfo object though.
var urlLoader:Loader = new Loader();
//urlLoader.
//urlLoader.dataFormat = URLLoaderDataFormat.BINARY;
urlLoader.addEventListener(Event.COMPLETE, onLoadComplete);
urlLoader.addEventListener(ProgressEvent.PROGRESS, onLoadProgress);
startTime = getTimer();
urlLoader.load(new URLRequest(url));
}
function onLoadProgress(e:ProgressEvent):void
{
speedTxt.text = new String(NetworkSpeedUtil.calculateKBps(e.bytesLoaded, startTime, getTimer()-startTime)) + "KB/s";
percentTxt.text = new String(Math.round((e.bytesLoaded / e.bytesTotal) * 100)) + "%";
}Note:
Please read the Example File.fla code comments to see how you can implement this into your own Adobe AIR or AS3 projects!
