Progress returns 0 when completed

[Hulio]

Why is this happening? The value is 0, not 1, when it is fully loaded.

 

	/** A value between 0 and 1 indicating the overall progress of the loader. When nothing has loaded, it will be 0; when it is halfway loaded, progress will be 0.5, and when it is fully loaded it will be 1. **/
	public function get progress():Number {
		return (this.bytesTotal != 0) ? _cachedBytesLoaded / _cachedBytesTotal : (_status == LoaderStatus.COMPLETED) ? 1 : 0;
	}

I cannot reproduce that issue - could you please post a sample FLA (and any support files) that I could publish to see this happen? Are you 100% sure that your asset has fully loaded and not failed? How are you checking that? Is the "status" LoaderStatus.COMPLETED (2)?

Allright, here's the code

import flash.display.Sprite;
import flash.text.AntiAliasType;
import flash.text.Font;
import flash.text.StyleSheet;
import flash.text.TextField;
import flash.text.TextFieldAutoSize;

TweenPlugin.activate([AutoAlphaPlugin]);
LoaderMax.activate([imageLoader]);

	}

Thanks for your reply!

It's because you set autoDispose:true - it actually did correctly report progress as 1 when the LoaderMax completed, but when it disposed itself immediately after that, it dispatched a PROGRESS event to notify that it has been emptied (thus progress == 0 because there were no loaders in it anymore). I just posted an update, though, that will skip that last PROGRESS event when it has been disposed.

So true, I didn't even think about that. Thanks mate!
