如何在 Discord.js 中做出随机响应

The title explains it I guess. I have no code written down and it would be nice if someone explains the steps to the code. I want it to send a random link for a wallpaper from a website each time the command 'a wallpaper' is used. Any helpers?

推荐答案

client.on('message', (message) => {
 if (message.content.startsWith('!wallpaper')) {

// Here you can choose between creating your array with your own links or use a api that will generate it for you. For now i'll use an array

  const wallpapers = [
   'https://cdn.discordapp.com/attachments/726436777283289088/734088186711769088/images.png',
   'https://cdn.discordapp.com/attachments/726436777283289088/734088144730718258/images.png',
   'https://cdn.discordapp.com/attachments/726436777283289088/734087421918183484/images.png',
   // You can add as many as you want
  ];
  // Here we will create a random number. Math.random only creates a randomly generated number between 0 and 1.
  const response = wallpapers[Math.floor(Math.random() * wallpapers.length)];
  message.reply(response);
 }
});
