Sound libary by Devils Child
(Posted 20 years ago)
hello!
are you looking for a good sound libary?
here ya go:

how it works:
you have to call createsound like that:
CreateSound("Sound\Test.wav")


within this command he loads the sound from your disk. when you play the sound again, he doesn't have to load it again, because it IS already in the RAM, so he just plays it from RAM.
this is practical because if you have got a complicated game, he doesnt have to load the sound of the last level while playing the first ;-)
and you dont have to make 20 values global and then load them apart! 
Type Sound
	Field path$, snd, snd3d
End Type
Type Channel
	Field ch
End Type

Function InitSoundLib(path$)
CreateListener(Cam)
End Function

Function FreeSoundLib()
For snd.Sound = Each Sound
	If snd\snd Then FreeSound snd\snd
	If snd\snd3d Then FreeSound snd\snd3d
	Delete snd
Next
End Function

Function CreateSound(path$, ent = 0, volume_times = 1)
For snd.Sound = Each Sound
	If snd\path$ = path$ Then
		For i = 1 To volume_times
			ch.Channel = New Channel
			If ent Then ch\ch = EmitSound(snd\snd3d, ent) Else ch\ch = PlaySound(snd\snd)
		Next
		Return
	EndIf
Next
snd.Sound = New Sound
snd\path$ = path$
snd\snd = LoadSound(path$)
snd\snd3d = Load3DSound(path$)
CreateSound(path$)
End Function

Function UpdateSoundLib()
For ch.Channel = Each Channel
	If ChannelPlaying(ch\ch) = False Then
		Delete ch
	Else
	EndIf
Next
End Function

"when you play the sound again, he doesn't have to load it again" - But Blitz3D doesn't do that. He only loads everytime IF you use PlayMusic().

When you use LoadSound it's tainted in the RAM so next time you play it there wouldn't be a slowdown such as Playmusic has (that's also why I convert all my music into WAVs or MP3s, to load them with LoadSound as not to have Blitz3D loading them everytime and causing that HD slowdown in your game. And you have more control over when to play it or not).
