Hi, quite analogous to the static class that is being widely used to accelerate images in your gfx card, I also made a static class which plays sampled media sounds, like .wav files
All you have to do is put this class in your project tree, initialize all the sounds by calling this once anywhere: SoundHandler.get().loadSoundFx();
and whenever you need to play a sound just call: SoundHandler.get().play(“boom1”);
I am also pretty much a beginner, so I hope other beginners can make good use of this class too. If you have any questions or comments, reply to this thread, or email me at k.verbist@student.tudelft.nl
I am also interested in what the advanced programmers have to say about this class.
