I wanted a module to load sounds sequentially based on a name and a number of sounds (eg "bob1.wav", "bob2.wav", etc) and to play a random sound from that list.

Here is my solution.

After importing this, create an instance of the class:

foosoundlist:soundlist = new soundlist

To load all wav files in the data directory starting with "foosound" you would do:

foosoundlist.init("foosound",5)

where 5 would be the number of sounds of that name that you have in the data directory.

Each one of these gets its own sound object.

Then, to play a random sound out of the list:

foosoundlist.randsound()

Code is as follows:

Import main
Class soundlist
	Field sounds:Sound[10]
	Field lastsound:Int
	Field chan:Int
	Field numsounds
	Field currentsoundchannel:Int
	
	Method addsound(soundname:String)
		sounds[numsounds]=LoadSound(soundname)
		numsounds = numsounds + 1
	End Method
	
	Method init(name:String, number:Int)
		For Local i:Int = 1 To number
			
			addsound(name+i+".wav")
		Next
	End Method
	
	Method randsound()
		Local i:Int = Rand(numsounds)
		'PlaySound sounds[i], currentsoundchannel
		currentsoundchannel=currentsoundchannel+1
		If currentsoundchannel > 16 currentsoundchannel = 0
	End Method
End Class

I'm interested in any improvements that anyone could suggest.

One question: what do we have for error checking? Can we check if a file exists in a directory? Can we check if a sound or picture is actually loaded before we try to access it and get the dreaded memory violation?
