Hiya Again :)

I was wondering about the status of openAL... do any of the openAL test classes (from org.lwjgl.test.openal) work ? I have only gotten exceptions (I've supplied sound files that exist for String[] args, of course). I guess they are marked as a "work in progress", but I'd like to make sure.

If they don't work yet, what would be a simple code snippet that just loads and plays a simple sound file ?

Thanks,
sprite

Hi Sprite!

Exactly what kind of exceptions are you getting? I use LWJGL 0.6 and all tests works for me (at least the basic ones). I also use OpenAL for a SoundAPI written for josrts.org and haven't experienced any problems so far.

Hey : )

I'm using LWJGL 0.7 rite now; in specific I'm trying to run org.lwjgl.test.openal.PlayTest. I provide "/data/chimes.wav" (hehe, the windows chime) as the argument and I get the following exception:

Code Select

java.io.IOException: Stream closed
	at java.io.BufferedInputStream.ensureOpen(Unknown Source)
	at java.io.BufferedInputStream.read(Unknown Source)
	at java.io.DataInputStream.readInt(Unknown Source)
	at com.sun.media.sound.WaveFileReader.getAudioFileFormat(Unknown Source)
	at com.sun.media.sound.WaveFileReader.getAudioInputStream(Unknown Source)

	at org.lwjgl.test.openal.PlayTest.execute(Unknown Source)
	at org.lwjgl.test.openal.PlayTest.main(Unknown Source)
java.lang.NullPointerException
	at org.lwjgl.test.openal.PlayTest.execute(Unknown Source)
	at org.lwjgl.test.openal.PlayTest.main(Unknown Source)
Exception in thread "main"

I've tinkered with other things but I have no idea what's wrong. I got stuff like this with 0.6 as well. I have no idea why I'm getting a NullPointerException. Am I using the wrong format, or what ?

*confused*

No, that's just a plain and simple file-not-found error, Java style...

"/data/chimes.wav" <= implies that the file is in a directory under [windows] [cde...]:\data\chimes.wav or [linux] /data/chimes.wav

Code Select

new File(".","data/chimes.wav") is probably what you want (if my telepatic abilities are strong enough ;)

EDIT: nah, you probably didn't want any chimes.waw file :wink:
