如何检测何时发生反应？

Question

我目前有一个 Discord 机器人，它读取处理游戏服务器面板的 API 的信息。 在这个 Bot 中有启动/重新启动/停止/终止服务器的任务。我想为最终用户提供选项，以对机器人发布的嵌入做出反应，并做出某种反应来触发这些任务。 机器人发布的命令和嵌入是：

当前检查触发了哪个反应的代码如下所示：

message.channel.send(embed).then(async (sentEmbed) => {
                                sentEmbed.react("????")
                                sentEmbed.react("????")
                                sentEmbed.react("????")
                                sentEmbed.react("❌")
                                const filter = (reaction, user) => {
                                    console.log(reaction.emoji.name)
                                    return reaction.emoji.name === '????' && user.id === message.author.id;
                                };
                                const collector = sentEmbed.createReactionCollector(filter, {time: 20000});

                                collector.on('collect', (reaction, user) => {
                                    Client.startServer(args[0]).then((response) => {
                                        const start_embed = new Discord.MessageEmbed()
                                            .setTitle(response)
                                            .setColor(settings.embed.color.default)
                                            .setFooter(settings.embed.footer);
                                        message.channel.send(start_embed);

                                    }).catch((error) => {
                                        message.channel.send(client.embederror(error))
                                    });
                                });
                                const filter2 = (reaction, user) => {
                                    return reaction.emoji.name === '????' && user.id === message.author.id;
                                };
                                const collector2 = sentEmbed.createReactionCollector(filter2, {time: 20000});
                                collector.on('collect', (reaction, user) => {
                                    Client.restartServer(args[0]).then((response) => {
                                        const restart_embed = new Discord.MessageEmbed()
                                            .setTitle(response)
                                            .setColor(settings.embed.color.default)
                                            .setFooter(settings.embed.footer);
                                        message.channel.send(restart_embed);
                                    }).catch((error) => {
                                        message.channel.send(client.embederror(error))
                                    });
                                });
                                const filter3 = (reaction, user) => {
                                    return reaction.emoji.name === '????' && user.id === message.author.id;
                                };
                                const collector3 = sentEmbed.createReactionCollector(filter3, {time: 30000});
                                collector.on('collect', (reaction, user) => {
                                    console.log(`User Stopped There Server`);
                                });
                                const filter4 = (reaction, user) => {
                                    return reaction.emoji.name === '❌' && user.id === message.author.id;
                                };
                                const collector4 = sentEmbed.createReactionCollector(filter4, {time: 30000});
                                collector.on('collect', (reaction, user) => {
                                    console.log(`User Killed There Server`);
                                });
                            })

此代码用于检测对消息的反应，但是当用户对任何反应做出反应时，它会运行所有触发代码，因此机器人发布了两个嵌入，我已将它们定义为机器人在反应时应输出的内容触发。

我只想让用户点击一个反应，然后机器人做一些事情，然后用户可以点击另一个，机器人做其他事情。

Answer 1

问题是您使用了 4 次 collector.on("collect") 而不是使用 collector2、collector3 和 collector4

最好不要有这样的变量，因为它表明你可能会感到困惑

另外，你不应该有 4 个不同的过滤器和收集器，尤其是因为你重复了很多代码

const validEmojis = ['?', '?', '?', '❌'];

const filter = (reaction, user) => {
  return validEmojis.includes(reaction.emoji.name) && user.id === message.author.id;
};

const collector = sentEmbed.createReactionCollector(filter, { time: 20000, maxEmojis: 1 });

collector.on('collect', (reaction, user) => {
  const name = reaction.emoji.name;
  //you only use it in two cases but I assume you will use it for all later on
  const embed = new Discord.MessageEmbed()
    .setColor(settings.embed.color.default)
    .setFooter(settings.embed.footer);

  if (name === '?' || name === '?') {
    const method = name === '?' ? "startServer" : "restartServer";
    Client[method](args[0])
      .then(response => {
        embed.setTitle(response);
        message.channel.send(start_embed);
      }).catch((error) => {
        message.channel.send(client.embederror(error))
      });
  } else if (name === '?') {
    console.log(`User Stopped There Server`);
  } else if (name === '❌') {
    console.log(`User Killed There Server`);
  }
});
