【问题描述】：

实际上，我尝试使用 discord.js 创建一个机器人并尝试执行帮助命令。

我不明白为什么我的循环会这样做（我知道这不是一个好方法）

let i = 0;
const embed = new RichEmbed();

if (args.length < 1) 
  embed.setColor('#5B4DCA');
  while (i < list_groups.length) 
    let x = 0;
    embed.setTitle(`$list_groups[i]`)
    while (x < groups.length) 
      if (groups[x] === list_groups[i]) 
        embed.addField('test1', 'test2')
      
      x++;
    
    message.channel.send(embed)
    i++;
  

“Modérations”应该显示一个命令，“level & rank”也是，“Outils”4 命令和“Sondage”也是

要回答你的问题，需要了解list_groups的结构

"list_groups" 包含所有组的列表，它由 this 设置（nb : bloc of code）和 "groups" 它是命令的属性，看起来像一个类别` if (!list_groups.includes (f.help.groups)) list_groups.push(f.help.groups) `

请显示您的exports.help 块之一。

【参考方案1】：

我认为你的解决方法不对。如果您将有超过 10 个组，机器人将发送垃圾邮件命令列表。如果args.length===0，则显示所有类别列表的第一种方法，如果 args !==0 您尝试查找此类别中的所有命令。要嵌入不和谐，您只能添加 18 个字段，因此如果您在 categroy 中有超过 18 个命令，您将收到 api 错误。所以你需要将命令拼接到页面上。

如果 args.length === 0，或命令组未罚款，此代码将显示所有类别。 如果组被罚款机器人在组中发送带有命令的嵌入消息（最多 10 个），如果页面超过 1，则响应消息，因此用户可以通过响应更改页面。

   const Discord,RichEmbed = require('discord.js');

            //Show user all allowed groups commands 
            let commandCategories = bot.commands.map(command => `!help $command.help.groups`).filter(onlyUnique).join('\n') //find all categories and get onlyUnique
            let helpMessage = `**The list of command groups:**\n\n $commandCategories`
            let Embed = new Discord.RichEmbed()
                .setAuthor(message.author.tag, message.author.displayAvatarUrl)

【讨论】：

感谢代码，实际上使用此代码，不会显示任何命令，但我会在您的代码的帮助下重新编码，我对嵌入有更好的理解。对不起我的英语，我对这种语言真的很差

那是显示命令名称，但是你可以修改Array args列表，只需将其添加到allCommands.push( name: command.help.name, description: command.help.description, )
