我如何让机器人在我对它的信息做出反应后做某事？

Question

我试图让机器人等待用户的反应，但我不知道如何设置它。我已经试过了，我也在第一部分中加入了const过滤器，但是当它对消息作出反应时，使用了1️⃣ 机器人回答。

message.channel.send(`the current number is:  ${number}`).then(message => {
    message.react('1️⃣')
    message.react('2️⃣')
    message.react('3️⃣')
});

const filter = (reaction, user) => {
    return ['1️⃣', '2️⃣','3️⃣'].includes(reaction.emoji.name)
        && user.id === message.author.id;
}

message.awaitReactions(filter, { max: 1, time: 20000, errors: ['time'] })
    .then(collected => {
        const reaction = collected.first();
        if (reaction.emoji.name === '1️⃣') {
            message.reply('you reacted with 1');
        } else if (reaction.emoji.name === '2️⃣') {
            message.reply('you reacted with 2');
        } else {
            message.reply('you reacted with 3');
        }
    })
    .catch(collected => {
        message.reply('game has ended');
    });

Answer 1

我看不到表情符号，但我会告诉你我是如何做到的（注意：我使用的是一个异步函数，所以我不必使用大量回调，我个人更喜欢它而不是。然后链接）：

const msg = await message.channel.send(`the current number is:  ${number}`);
await Promise.all([
    message.react('1️⃣'),
    message.react('2️⃣'),
    message.react('3️⃣')
]);

const filter = (reaction, user) => ['1️⃣', '2️⃣','3️⃣'].includes(reaction.emoji.name) && user.id === message.author.id;
const collector = msg.createReactionCollector(filter, { time: 120000, max: 1 }); //setup here

collector.on('collect', async () => {
    //... your logic after reaction here
});

Discord.js客户端对象具有messageReactionAdd（以及Remove、RemoveAll和当bot删除表情反应时）事件触发器，这为您提供了一个相当简单的解决方案。

let targetUser = "some-long-number"; 
// replace this with the author of the person who fires your 
// reaction related command in your client.on('message') def.
client.on('messageReactionAdd', (reaction, user)) {
  console.log('sample message to verify base functionality');
  if (user != targetUser) return null;
  switch (reaction.emoji.name) {
    case "1️⃣":
      message.reply("you reacted with 1️⃣");
      break;
    case "2️⃣":
      message.reply("you reacted with 2️⃣");
      break;
    case "3️⃣":
      message.reply("you reacted with 3️⃣");
      break;
    default:
      // in case you want to log when they don't reply with the correct emoji.
      break;
  }
}

我可能在某个地方打错了，请随意更正。如果message.reply（） 。
