Basic Example

This example will demonstrate how to join a voice channel and play resources, with some best practice assistance on making sure you aren't waiting indefinitely for things to happen.

To achieve this, the example sets some fairly arbitrary time constraints for things such as joining voice channels and audio becoming available.

import { Client, VoiceChannel, Intents } from 'discord.js';

	const resource = createAudioResource('https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3', {
		inputType: StreamType.Arbitrary,
	});

	player.play(resource);

	return entersState(player, AudioPlayerStatus.Playing, 5000);
}
