Creating a Pause Command

In this guide, we will learn how to create a pause command in your Discord bot using Discord Player. The pause command will pause the currently playing song in the voice channel. If the song is already paused, it will resume playing.

Design Planning

Before we dive into the code, let's plan the design of our pause command:

1. Command Definition: We will define a new slash command named pause using SlashCommandBuilder.
2. Timeline Retrieval: We will use the useTimeline hook to get the current timeline.
3. Pause State Handling: We will invert the pause state of the timeline to pause or resume the queue.
4. Response: We will send a message indicating the current state of the queue.

import { SlashCommandBuilder } from 'discord.js';
import { useQueue, useTimeline } from 'discord-player';
 
export const data = new SlashCommandBuilder()
  .setName('pause') // Command name
  .setDescription('Pause the currently playing song'); // Command description
 
export async function execute(interaction) {
  // Get the queue's timeline
  const timeline = useTimeline();
 
  if (!timeline) {
    return interaction.reply('This server does not have an active player session.');
  }
 
  // Invert the pause state
  const wasPaused = timeline.paused;
 
  wasPaused ? timeline.resume() : timeline.pause();
 
  // If the timeline was previously paused, the queue is now back to playing
  return interaction.reply(`The player is now ${wasPaused ? 'playing' : 'paused'}.`);
}

In this example:

• We define a new slash command named pause using SlashCommandBuilder.
• We use the useQueue and useTimeline hooks to get the current queue and timeline.
• If there is no active player session, we reply with an appropriate message.
• We invert the pause state of the timeline to pause or resume the queue.
• We reply with a message indicating the current state of the queue.
