If you want to know how to put sound into your mission here's a short tute,
Get Goldwave from here,
http://www.goldwave.com/release.htmlThen record your voice using Goldwave and a mic and then save it as .ogg. You don't need to download Goldwave actually but its a very good and handy program. Any .ogg will do. One from the campaign folder or single player missions folder will do fine.
Next create a new folder in the folder where your mission is. Call it sound. It will be created in the Flashpoint folder summit like this,
C:\Program Files\Codemasters\Operation Flashpoint\Users\yourname\missions\yourmissionname
Next you must create a Description file using the notepad or wordpad.
Save it as Description.ext. Where it says save as type: set it to All Files
In this notepad file put this,
class CfgSounds
{
sounds[] = {Yoursoundfilename };
class Yoursoundfilename
{
name = "Yoursoundfilename";
sound[] = {"Yoursoundfilename.ogg", db+20, 1.0};
titles[] =
{
0, $STRM_Yoursoundfilename
};
};
You can cut and paste that bit up there.
Save it.
If you've put everything in the right place then the file should appear in the editor. Just make a trigger and in the second page you can call it up from the same place as the BIS default sounds.
