[Xerte-dev] Re: Export and first go at new way of Tracking

[Ron Mitchell]

Hi Tom
I've put the latest svn code (including these updates) in place on the
techdis /xot install
The export and ability to view html 5 locally seems to work great! However
it seems I can't select to export using only the flash engine e.g. can't
un-tick Use HTML5 Engine and with both selected I only get index.htm with
HTML5 playback not Flash also? The same applies to a localhost xampp install
too. Although both are updates not new installs.

Haven't tried the scorm exports yet but the above applies to both deployment
and archive.

HTH
Ron

Subject: [Xerte-dev] Export and first go at new way of Tracking

I've will commit several changes shortly.

- Be aware that I have changed the Engine, the preloader AND xenith.js!

1. Export

I implemented a first pass of the export. It's a first pass because there
are still discussions going on, on how to implement export. For now I've
added two checkboxes: Use HTML5 (checked by default) and Use Flash (off by
default).

  - If none is chosen, export creates an html5 object
  - If both are chosen, both are available, but no automatic failover
(index.htm for html5 and index_flash.htm for flash)
  - With any of the scorm packages only one engine will be exported with a
preference for html5.
  - I cleaned up a lot of file with respect to the javascript helper
functions that are needed by xmlEngine.swf. They are now in rlohelper.js.

2. SCORM

I implemented a new way of SCORM tracking in flash and in HTML5. For now, it
will track page visits. I will write up an article of the design, and how
you can add tracking to new pages (if you only want to know if and for how
long a page is visited, you don't need to do anything.)

- SCORM tracking is determined on export.
     a. If you export a Scorm2004 zip, you get full scorm 2004 tracking
     b. If you export a scorm 1.2 package, you et full Scorm 1.2 tracking
     c. If you export a deployment zip, you get no tracking

- The quiz tracking is broken for now. I'll fix that in the upcoming
week(s).

- I plan to add Tin Can tracking as well (but there are some challenges to
work out there...)

- In xenith.js, I changed the x_changePage() API function, in that it no
longer expects x_currentPage to be set to the correct value before calling,
but it expects the new value as a parameter.  In that way, I have the old
page (in x_currentPage) and the new page (in the parameter) in that fuction,
and I can handle all tracking in x_changePage. So to move a page forward
call x_changePage(x_currentPage+1); BEWARE that you MUST NOT CHANGE
x_currentPage here, so do NOT call x_changePage(x_currentPage++).

Tom
