Description

The complete Moodle SCORM player reloads each time when using it's content-tree-menu to navigate to another content page from a SCORM package. Loading the player takes mostly much longer than the actual content page. Like this, navigation through the content of SCORM packages is slow and feels unpleasant.

Possible solution: When the client uses the content-tree-menu to navigate to another SCORM content page, just load the content page in the existing iFrame without reloading the complete SCORM player. VDAB ( http://vdab.be ) is working on this solution.

In the diagram you can see the concept for a solution as we have in mind. This goos further than a patch for player.php in the SCORM module. We think that a new version of player.php can improve the performance of the SCORM player significantly. We would realy appreciate:

  • your feedback on the concept.
  • your feedback on the code.

Could you suggest how we can enter the code in the community for review? Is there a branch that we can use?

HI Gerd, we cannot provide any feedback on the code as you have not provided any. - The best way to allow review is by adding a patch to this tracker issue for review. As to the "concept" - it "seems" like an ok idea, however I suspect it will cause problems for objects that display the TOC. However we are happy to review any code that you attach.

Dan,
Following your questions, you will find:

  • Fastfileparser.php
  • loadsco.php to initiate the Fastfileparser.php

We have put one of our oldest and simplest packages on an ftp server. I will send you the details by email, because this content is not for public use.
