Discord.js将嵌入发送到已创建的新通道，并随机将2个用户配对以进行战斗

const Discord = require('discord.js');
const client = new Discord.Client();

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}`);
});

client.on('message', message => {
  if (message.content === '!battle') {
    const channel = message.guild.channels.create('battle-channel', {
      type: 'text'
    }).then(channel => {
      const embed = new Discord.MessageEmbed()
        .setTitle('Battle')
        .setDescription('A battle has started!')
        .setColor('#ff0000');

      channel.send(embed);
    }).catch(console.error);
  }
});

client.login('your-token');

client.on('message', message => {
  if (message.content === '!battle') {
    const members = message.guild.members.cache.filter(member => !member.user.bot);
    const randomMembers = members.random(2);

    const embed = new Discord.MessageEmbed()
      .setTitle('Battle')
      .setDescription(`${randomMembers.first()} vs ${randomMembers.last()}`)
      .setColor('#ff0000');

    message.channel.send(embed);
  }
});
