well for the life of me i can't get the thunder to work in my map at all every tutorial i have read i have tried with no luck.

can anyone please detail what the script procedure is please and what i got to put in ones map

There is a tutorial in the CoDUO section which works. "Custom sounds" or something it's called.

This is what works for me.

main()
{
thread thunder_MAPNAME();
thread thunder_MAPNAME2();
}

thunder_MAPNAME()
{
    wait 120 + randomint(120); 

      boom = spawn("script_origin", (-8442, 7018, 1854));
       boom playsound("elm_thunder_MAPNAME");
}
thunder_MAPNAME2()
{
    wait 120 + randomint(120); 

      boom2 = spawn("script_origin", (-8548, -209, 1854));
      boom2 playsound("elm_thunder_MAPNAME2");

It's in it's own little .gsc file that the main gcs refers to. It plays two thunder sounds at random. You will need add all the little niceties of fixing names and making sure the soundaliases are right.

Cut it in half for one sound
