BitmapAnimation now only draws the first frame when added to the stage stopped.

DelayedBitmapAnimation now has a percentComplete value, that, like the ProgressBar component, returns a value between 0 and 100.

The updated source code can be found using the download links of this post.

Nicolas, we should add a simple
if (_progressPercent >= 1) _progressPercent = 1;
after the calculation in line 72.

After each draw command, the progress is calculated. Exposed through a getter, the value can be visualized by other means.

I wanted to eliminate the freeze after the loading finishes by integrating the state of the frame processing into the overall loading/progress bar.

A couple of comments:
- the play() behavior when added to stage caused me a slight confusion, since normal MovieClips can be stopped before added to stage and stay that way. Also in your example use (my exact case), the BitmapAnimation shouldn’t auto-play anyway, but only react to the mouse.

- I’ve added totalFrames and currentFrame getters.

- play() updates the _index so currentFrame works properly.

You are right, receipts are a must. I did not mention this in the article but the POS should at least be able to handle the money transaction (cash, credit/debit card) and receipt printing.

The cash register I installed has a built in receipt printer. It prints the date of purchase and the transaction amount. If a customer wishes to return an item, and if necessary, the order can be looked up in the database using these two values.
