No audio in WASM build #124
Description
Hello, first off, loving this library 🙂
I'm struggling to get a wasm build that actually plays sounds. I'm not getting any errors or exceptions when using include_bytes! and a simple playing of a StaticSound that way. It is odd since I hear things fine for a desktop build, but not for wasm. Since I'm not getting any errors or panics from Kira while playing the sound, I'm wondering if this is an issue with something particular about my wasm build setup.
impl Audio {
pub fn new() -> Self {
let manager = AudioManager::<DefaultBackend>::new(AudioManagerSettings::default()).unwrap();
Self {
manager,
sounds: HashMap::new(),
}
}
pub fn play(&mut self, name: &str) -> StaticSoundHandle {
let sound = self.sounds.get(name).expect("Sound not found");
let snd = self.manager.play(sound.clone()).unwrap();
snd
}
pub fn load_from_bytes(&mut self, name: &str) {
let src = include_bytes!("../resources/candle_fire.wav").to_vec();
let mut sound_bytes = vec![];
for byte in src {
sound_bytes.push(byte);
}
let sound = StaticSoundData::from_cursor(Cursor::new(sound_bytes))
.expect("Failed to load sound file");
self.sounds.insert(name.to_string(), sound);
}
} gs.audio.load_from_bytes("candle");
gs.audio.play("candle").set_volume(-6.0, Tween::default());<html>
