So far so good.

I more than welcome feedbacks to improve my understanding.

Hi Hilaire...
I read it.
If you, hopefully, continue to document your journey in AIDA.
It would have been very good for me to study, when I started my own journey for nearly two years ago.
And now have a working App.
(The App is a platform for Interactive fiction with integrated sounds, and pictures where the server for  runs a Dolphin Smalltalk image)
AIDA is a tool with so many fine things for a Smalltalker going to the web.
So more tutorial material from a newcomer to AIDA like that, you have started, would be very helpfull for everybody.
And your blog layout is just so nice !

Regards

The world is just one big friendly surprise-

Hi Søren

Thanks for the interests. When I'll find out interesting stuff, I will
continue to write notes then.

As Janko, I am curious about your web application.
I am also curious to read from other, what are you doing with Aida? It
could lead to interesting exchanges and discussion.

Thanks

Hilaire

Hi Hilaire
A short note concerning the archetecture of my PicturesInYourHead app.
In interactive fiction the story unfolds depending on the activity of the reader, the reader 'reads', then decides for some response and the next section of text
is presented depending of this response.
In the PicturesInYourHead app. The server may respond on
one Textual channel, two sound channels and three image channels.
The channels may be updated each time the user responds.
Furthermore the authoring platform makes it possible to set up delayed action events on server side.
When such an event occurs one or more channels may have to be updated too.
-------
I knew Smalltalk but had no knowledge of  Server or Web architecture, HTML or CSS.
But studying the AIDA architecture and bolts and nuts - ' How is this happening?', 'Can I copy this trick?'  i ended up with
the following architecture of the client server interface:
--------
1 Sound channels
The server maintains two queues of soundfiles to play.
Whenever the client observes it has no sound to play/playing it asks the server to deliver one.
This request is set up through a timer controlled ajax (soundhandling itself needed javascript, was not that simple)
I could not use a page refresh, because ongoing playing sounds was then disturbed, (repeated/ truncated/stopped).
2 Image channels
The server will update each channel at each reader response if needed.
I use an Ajax construct for that, so only the Image page elements are updated
because a page refresh would disturb an ongoing sound.
3 Textual channels
This channel is updated through ajax too, to just change this channels element on the page.
4 Delayed events on server side.
This is actually 'COMET' architecture i suppose.
A timed request is repeatedly sent to the server from the client.
And if a delayed event has happened, the server will ask the channels to update the client.

Here is a link to the non web parts of the platform (Warning everything is in danish) ;-)

many regards

Hi Søren,

I changed the subject to match the discussion topic.
Your project looks like an interesting one, do you have any screen shot
or video to share with us?

Which exact version of Aida are you using?
I guess you have the Desktop editor developed with Dolphin as well?

Thanks

Hilaire

Hi Hilaire
Thanks for your interest in the PicturesInYourHead app !
Here is a single screen shot where the user is caught populating his library with an Interactive fiction story.
More screenshots can be found here: https://www.facebook.com/groups/PicturesInYourHead/
A screencast video will show up later in this facebook group.
The project uses the AIDA 6.0 Dolphin Version. Ported by Bruno Buzzi Brasesco I should say I am very thankfull to Bruno for this work :-)
And to Janko for the AIDA platform of course!
The combined editor/presenter is written in Dolphin 6.03.
In the following link you will find a lot of instruction videos which presents the facillities.
of the editor part. http://picturesinyourhead.vpweb.dk/Vejledninger-og-videoer.html
Video 3 and video 7 presents many of the facillities. Video 0 presents principles and exerpts of three interactive fiction stories.

Concerning the architecture I forgot to mention that I created a proxy layer between the Dolphin generated windows and views and the channels to  the browser.
This Idea turned out to work very well.
Many regards
Søren
