Get Goldwave.
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 or select a music file and convert it in Goldwave. .ogg is at the bottom of the "save as" list I think.
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. Obviously you can also call it from a script with the playsound command or the say command etc.
I'm probably telling you stuff you already know. If not then post back with any problems and we'll help you get through them.
