检查机器人是否仅被提及

Question

所以让我把场景布置一下：（这些不是代码实际所说的，但为了解释的篇幅，我把它写得很短）

A 发送此消息：

@Bot slap @membername

机器人回复

@messageauthor slapped @membername

完美执行，代码运行良好。

示例 2

@Bot slap @membername (with any number of args following the second mention) 或者 @bot slap (anything can go here doesn't matter) @membername

机器人回复

@messageauthor no can do

完美执行，代码运行良好

示例 3

@bot slap

机器人回复

@bot slapped @messageauthor because they didn't specify who to slap

完美执行，代码运行良好

示例 4（也是我遇到问题的那个）

@Bot slap membername 没有提及 或者 @Bot slap asdfg

机器人回复

@messageauthor slapped @Bot

我已经尝试了几十种不同的想法来让它发挥作用，以便它会以“不能做”的响应来响应。我有两种可能的解决方案。

1. 让@bot 像普通前缀一样被解析出来（因为我的前缀不是@，所以不成功，它很愚蠢，没有人会使用，因此发送的所有命令都只与机器人提及一起发送）。
2. 不知何故使这个（和其他类似的命令）需要第二次提及。
3. 我也愿意接受其他想法。

代码如下：

const Discord = require('discord.js')
const sarcasm = require('../assets/json/sarcasm.json'); //has variations of no can do but with major sarcasm in it

module.exports.run = async (bot, message, args) => {
    let user = message.mentions.users.last();

    const notargetEmbed = new Discord.MessageEmbed()
        .setColor('#ff6600')
        .setTitle('Slap')
        .setDescription(`<@` + bot.user.id + `> slapped <@` + message.author.id + `> because they didn't specify who to slap, so it boomeranged.`)
        .setImage('my_image_gif_here.gif')
        .setFooter('Discord Server Name', 'icon_here.png')

    if (!args.length) {
        return message.channel.send(notargetEmbed);
    }

    if (args[1]) {
        return message.channel.send(`<@${message.author.id}>, ` + sarcasm[Math.floor(Math.random() * sarcasm.length)]);
    }

    const slapEmbed = new Discord.MessageEmbed()
        .setColor('#ff6600')
        .setTitle('Slap')
        .setDescription(`<@` + message.author.id + `> slapped <@` + user.id + `> across the face!`)
        .setImage('my_image_gif_here.gif')
        .setFooter('Discord Server Name', 'icon_here.png')

    message.channel.send(slapEmbed);
};

module.exports.help = {
    name: "slap"
}

解决问题的一个简单方法是确保消息有多次提及，并且第二次提及不是机器人提及。

// We cannot use `message.mentions.users` to get the mentioned users
// since the order of the users returned is not as they appear in the message.
// See https://discord.js.org/#/docs/main/master/class/MessageMentions?scrollTo=users
const mentionedUserIds = message.content
  .match(Discord.MessageMentions.USERS_PATTERN)
  .map(id => id.slice(2, -1));
const [_, userIdToSlap] = mentionedUserIds;

if (!userIdToSlap) {
  return message.channel.send(notargetEmbed);
}

if (userIdToSlap === bot.user.id) {
  return message.channel.send(`<@${message.author.id}>, ` + sarcasm[Math.floor(Math.random() * sarcasm.length)]);
}

整个代码：

const Discord = require("discord.js");
const sarcasm = require("../assets/json/sarcasm.json");

module.exports.run = async (bot, message, args) => {
  const mentionedUserIds = message.content
    .match(Discord.MessageMentions.USERS_PATTERN)
    .map(id => id.slice(2, -1));
  const [_, userIdToSlap] = mentionedUserIds;

  const notargetEmbed = new Discord.MessageEmbed()
    .setColor("#ff6600")
    .setTitle("Slap")
    .setDescription(
      `<@` +
        bot.user.id +
        `> slapped <@` +
        message.author.id +
        `> because they didn't specify who to slap, so it boomeranged.`
    )
    .setImage("my_image_gif_here.gif")
    .setFooter("Discord Server Name", "icon_here.png");

  if (!userIdToSlap) {
    return message.channel.send(notargetEmbed);
  }

  if (userIdToSlap === bot.user.id) {
    return message.channel.send(
      `<@${message.author.id}>, ` +
        sarcasm[Math.floor(Math.random() * sarcasm.length)]
    );
  }

  const slapEmbed = new Discord.MessageEmbed()
    .setColor("#ff6600")
    .setTitle("Slap")
    .setDescription(
      `<@` +
        message.author.id +
        `> slapped <@` +
        userIdToSlap +
        `> across the face!`
    )
    .setImage("my_image_gif_here.gif")
    .setFooter("Discord Server Name", "icon_here.png");

  message.channel.send(slapEmbed);
};

注意对于输入"@Bot slap @member for something"，上面的代码会打@member。如果您不希望这种行为，您可以添加另一个提前返回。

if (args.length > 1) {
  return message.channel.send(`<@${message.author.id}> Usage: @Bot slap @member`);
}
