Oh... you don't *have* to change the class names like I did in my example - that was just to
emphasize that it is the "class name", not the string in the "name=" property within the class
that is to be used with the playMusic command.
Ok. I have a few other things you should check:
The .ogg-files should be put in a folder named "sound" that is within the mission's own "mission folder". This is not to be confused with the folder named "Missions" where all the other missions you're editing are.
Lets say the mission in question is named "mytest" and is on the Desert Island. The mission.sqm is then in a folder named "mytest.Intro". Then, this is how it should be (something like this, at least):
...\OperationFlashpoint\Users\B-2-0\Missions\mytest.Intro\mission.sqm
...\OperationFlashpoint\Users\B-2-0\Missions\mytest.Intro\description.ext
...\OperationFlashpoint\Users\B-2-0\Missions\mytest.Intro\music\kitno.ogg
...\OperationFlashpoint\Users\B-2-0\Missions\mytest.Intro\music\tlp.ogg
Also, make sure that the description.ext isn't named "description.ext.txt". If you have Windows set to show
you the file extensions (like .exe, .zip, .doc, .txt and so on) then this should not be an issue.
However, it may be that you have a file that actually is called "description.ext.txt", but all you see in
Windows is "description.ext". Set the folder view to "Detailed List" (in stead of just "List" or "Icons").
Not sure what those view settings are called in your version of Windows, so...
Now, in that detailed list view, look at the column "Type" of your description.ext file. If it says "EXT-file", all is well and OFP should read it. If it shows "Text document" (again, not sure what it is called in the english version
of Windows, if that's what you have) it means that the file is actually named "description.ext.txt" and you need
to rename it. Navy_Seals had a note on that problem in his tute, so maybe I'm just grabbing for straws here.
So: check your folder structure and by all means name the "sound classes" just the way you had them. Make sure the .ext file really is an .ext file.
Now I *really* have to get some sleep... been an all-nighter here. Good luck!
