[Solved] Getting Paulscode Source - IllegalArgumentException

[Xenocider]

I been reading through Paulscode 3D SoundSystem Library http://www.paulscode.com/docs/SoundSystem/overview-summary.html and I can't find a way to get from Minecraft's SoundSystem to it's Library and then running .getSource("BgMusic").getSoundSequenceQueueSize();

 

This get's the java.lang.Class Library:

soundManager.sndSystem.currentLibrary()

is there a way from this point to run the Method .getSource()? I have looked at .getMethod() and .getMethods() but I can't quite understand what I can do with them.

 

Any help, tips or ideas would be most appreciated! Thanks!

I tried your suggestion to access it via reflection however it is throwing an IllegalArgumentException and I need some help. I'm not very experienced with reflection and so I had to read up on some tutorials before attempting it.

    public static Source getSource() throws NoSuchFieldException, SecurityException, InstantiationException, IllegalAccessException {
        Source theSource = null;
        LogHelper.info("Getting field..."); 
        Field field = MainEventHandler.soundManager.sndSystem.getClass().getDeclaredField("soundLibrary");
        if (field == null) {LogHelper.severe("The field is null!");} 
        else {
        field.setAccessible(true);
        LogHelper.debug("Getting soundLibrary!"); 
        Class<?> targetType = field.getType();
        Object objectValue = targetType.newInstance();
        Library soundLibrary = (Library) field.get(objectValue);
        if (soundLibrary == null) {LogHelper.severe("The soundLibrary is null!");} 
        else {
            theSource = soundLibrary.getSource("BgMusic");
        }
        }
        return theSource;
    }

 

The crash log:

I'd recommend:

try{
        Field field = SoundSystem.class.getDeclaredField("soundLibrary");
        field.setAccessible(true);
        Library soundLibrary = Library.class.cast(field.get(classMainEventHandler.soundManager.sndSystem));
}catch(Exception e){

}

Thanks so much GotoLink! It works perfectly! I had absolutely no idea how to do a reflection, so thanks a lot!
