So we've found a subtle but important bug. The callback "Scorm_Initialization_Complete" call runs within the thread that is spawned by the ScormManager. This limits the code that you can run in this handler. Unfortunately, there is not documentation that mentions this, so it's totally possible that someone out there is running non-thread safe functions, with no knowledge that their code is running in a thread that is not the main Unity script thread. This might not be a problem for many people who might be setting a flag or something, but if you are doing more scene setup on this event, you can have strange problems. We need to find a way to get that callback to run in the main Unity script thread, not in the thread spawned for the deserialization.

Environment: Windows 7 Pro
Browser: Internet Explorer 9
Unity: 3.5 2f2 Pro, iPhone Pro, Android Pro
RAM: 8GB
CPU: i7
Moodle: installed from Microsoft Web Platform Installer
Database: MySql
SCO: tutorial game, editted per instruction
Repro:

1. log in as admin into moodle
2. create a new course
3. register admin as a student
4. go to course editting, add a SCO package
5. browse to tutorial output zip package
6. switch over to student role
7. try to work thru the course
8. Unity boots up, and skybox appears. But it stops there due to the error at the top of this issue report

This example doesn't work with Unity 4x. Every time I make a SCORM package following this tutorial I am told I need to install the Unity web player.

In some cases, while running IE 8 or 9, the plugin crashes. Sometimes I get data before the crash, other times none.

In SCORM2004.cs and SCORM1.2.cs, the interactionTypeType enum is incorrect. The binding of the "multiple_choice" interaction type should be "choice", not "multiple_choice".

SCORM 2004 page RTE-4-48
Format: The format of the data model value shall be one of the
restricted tokens listed above (“true-false”, “choice”, “fill-in”,
“long-fill-in”, “matching”, “performance”, “sequencing”, “likert”,
“numeric” or “other”).

I have no idea about the specifics of SCORM, so I'm a little crippled for giving you more details.
I've also tried to do a DebugPrint on SubmitStudentData_imp, but didnt get output either.

Hi,
I've seen that the scorm.js file try to reach an element with id="console" in the html file. In the previous version of the plugin this element was a simple div before the footer, but now is missing and the scorm.js script doesn't complete its execution.

It is simply necessary to add again the

Thank you

The milliseconds are returned as the number of milliseconds rather than as a fraction of seconds, and can be returned as three digits, violating the CMITimespan format.

Example invalid output from the plugin for the timespan string:
0000:00:29.110

I appear to get random crashes when running iLearning. Some data is read, then it dies on a certain 'Get' request.

UnityEngine.Application.ExternalCall no longer works from a secondary thread, and so many of the calls that ScormManager and ScormAPIWrapper make now fail.
