Warning
Info
Hi,
my target is: select random a mp3 file in directory: assets/sounds
and start playing this....
if hardcode one file name the sound is played
but wanna have a random select file
the source code
use std::{fs, process::exit};
use rand::prelude::IndexedRandom;
use bevy::prelude::*;
fn main() {
getsoundfile();
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Startup, playsound)
.run();
}
fn getsoundfile() {
let mp3_files: Vec<_> = fs::read_dir("assets/sounds")
.unwrap()
.filter_map(|entry| entry.ok())
.collect();
let mut rng = rand::rng();
if let Some(random_file) = mp3_files.choose(&mut rng) {
println!("Zufällig ausgewählte MP3-Datei: {}", random_file.path().display());
} else {
println!("Keine MP3-Dateien gefunden!");
exit(99);
}
}
fn playsound(mut commands: Commands, asset_server: Res<AssetServer>) {
// MP3-Datei laden (im Ordner "assets/sounds/")
let randsoundfile: &str = getsoundfile();
let audio_handle = asset_server.load(randsoundfile.as_str());
// let audio_handle = asset_server.load(&randsoundfile);
commands.spawn(AudioPlayer::new(audio_handle));
}
Error:
