Question

我正在为JavaScript中的Discord构建一个简单的 投票机器人 ，现在，我正在尝试实现每位用户对一条消息的最大反应次数。

例如，假设我们为民意测验问题提供以下选项：

问题？

选项A

选项B

选项C

选项D

选项E

每个“选项”都是对机器人发出的消息的反应，我想确保用户 不能对做出反应 em> 3。

我的思路是让messageReactionAdd听众然后，当用户对4th time做出反应时，删除最后一个反应，并向他发送“您已投票3 times”之类的消息，请删除再次投票的反应。”
不过，我仍然试图在对象之间导航以找到总反应计数每个用户我可以找到总反应计数 每个表情符号，但这不是我所需要的。

有人可以给我一些见解吗？

用于发送消息的代码：

Embed = new Discord.MessageEmbed()
                .setColor(0x6666ff)
                .setTitle(question)
                .setDescription(optionsList);

                message.channel.send(Embed).then(messageReaction => {

                for (var i = 0; i < options.length; i++){
                    messageReaction.react(emojiAlphabet[i][0]);
                }

                message.delete().catch(console.error);
              });

尝试一下：

const {Collection} = require('discord.js')

// the messages that users can only react 3 times with
const polls = new Set()
// Collection<Message, Collection<User, number>>: stores how many times a user has reacted on a message
const reactionCount = new Collection()

// when you send a poll add the message the bot sent to the set:
polls.add(message)

client.on('messageReactionAdd', (reaction, user) => {
  // edit: so that this does not run when the bot reacts
  if (user.id === client.user.id) return

  const {message} = reaction

  // only do the following if the message is one of the polls
  if (polls.has(message)) {
    // if message hasn't been added to collection add it
    if (!reactionCount.get(message)) reactionCount.set(message, new Collection())
    // reaction counts for this message
    const userCount = reactionCount.get(message)
    // add 1 to the user's reaction count
    userCount.set(user, (userCount.get(user) || 0) + 1)

    if (userCount.get(user) > 3) {
      reaction.users.remove(user)
      // <@!id> mentions the user (using their nickname if they have one)
      message.channel.send(`<@!${user.id}>, you've already voted 3 times, please remove a reaction to vote again.`)
    }
  }
})

client.on('messageReactionRemove', (reaction, user) => {
  // edit: so that this does not run when the bot reacts
  if (user.id === client.user.id) return

  const {message} = reaction
  const userCount = reactionCount.get(message)
  // subtract 1 from user's reaction count
  if (polls.has(message)) userCount.set(user, reactionCount.get(message).get(user) - 1)
})

限制用户对消息的反应
