Question

所以，我尝试在我的 Discord 机器人上制作石头、纸、剪刀命令。这段代码的工作方式是用户对他/她选择的表情符号之一做出反应，机器人随机选择其响应并发送它。代码如下：

module.exports = {
    name: 'rps-game',
    description: 'play a rps game',
    async execute(message, args, Discord, client) {
        const rockemoji = '?'
        const paperemoji = '?'
        const scissorsemoji = '✂'

        const rpsembed = new Discord.MessageEmbed()
            .setTitle('A game of RPS')
            .setDescription('React to one of the emojis below!')

        const messageEmbed = await message.channel.send(rpsembed)

        messageEmbed.react(rockemoji)
        messageEmbed.react(paperemoji)
        messageEmbed.react(scissorsemoji)

        client.on('messageReactionAdd', async (reaction, user) => {
            if (reaction.message.partial) await reaction.message.fetch()
            if (reaction.partial) await reaction.fetch()
            if (user.bot) return
            if (!reaction.message.guild) return

            const rpschoices = ['?', '?', '✂']
            const unexchoice = rpschoices[Math.floor(Math.random() * rpschoices.length)]

            if (reaction.emoji.name === rockemoji && unexchoice === "?") {
                const unexwin1 = new Discord.MessageEmbed()
                    .setTitle('RPS results')
                    .addFields(
                        { name: 'Your Choice', value: '?' },
                        { name: 'Unex\'s Choice', value: '?' }
                    )
                message.channel.send(unexwin1)
                message.channel.send('Unex wins!')
                return
            }
            else if (reaction.emoji.name === paperemoji && unexchoice === "✂") {
                const unexwin2 = new Discord.MessageEmbed()
                    .setTitle('RPS results')
                    .addFields(
                        { name: 'Your Choice', value: '?' },
                        { name: 'Unex\'s Choice', value: '✂' }
                    )
                message.channel.send(unexwin2)
                message.channel.send('Unex wins!')
                return
            }
            else if (reaction.emoji.name === scissorsemoji && unexchoice === "?") {
                const unexwin3 = new Discord.MessageEmbed()
                    .setTitle('RPS results')
                    .addFields(
                        { name: 'Your Choice', value: '✂' },
                        { name: 'Unex\'s Choice', value: '?' }
                    )
                message.channel.send(unexwin3)
                message.channel.send('Unex wins!')
                return
            }
            else if (reaction.emoji.name === rockemoji && unexchoice === "?") {
                const unextie1 = new Discord.MessageEmbed()

问题：第一次使用时，机器人返回一条消息，第二次使用时，机器人返回两条消息，依此类推

如你所见，我已经尝试过返回，但它不会工作。

发生这种情况的原因是您在命令中添加了 messageReactionAdd 事件侦听器。每次调用您的命令时，都会创建另一个事件侦听器并将再次执行代码。您可以使用 awaitReactions，而不是将事件侦听器放在您的命令中。这些将允许您在消息发送后的一段时间内检查对消息的反应。例如：

const filter = (reaction, user) => {
    const rpschoices = ['?', '?', '✂']
    return rpschoises.includes(reaction.emoji.name) && user.id === message.author.id;
};
messageEmbed.awaitReactions(filter, { /*options*/ })
    .then(collected => {}) //your handler code here

您可以在 the docs 中阅读有关 awaitReactions 的选项和方法的更多信息。
