PlayMusicAtEntity

[FlawlessHappiness]

i should tell you how to stop it too... If you have this sound playing all through your game it will be very annoying!
This is how the script should look:


void LoopSound(string &in asTimer)
{
if(asTimer == "LoopSound")
{
if(GetLocalVarInt("StopLoopSound") == 1)
{
return;
}
PlaySoundAtEntity ("", "scare_whine_loop3.snt", "Player", 0, true);
AddTimer("LoopSound", 5, "LoopTimer");
}
}


Then if you want to stop the loop you just make a script that calls: SetLocalVarInt("StopLookSound", 1);



For the fade in sound:

This line can fade in sounds: PlaySoundAtEntity("", "break_glass_large.snt", "Player", 0, true);

The 0 determines how many seconds it should fade, until it has reached full volume

string = Letters
float = Numbers
bool = True or false
