每 5 秒发送一条消息 Client.on('ready', () => { });在 Discord.js

Question

我想每5秒发一条消息，第一个反应的用户给他10个币。

此代码无效，我现在收到错误回复：Uncaught TypeError TypeError: Cannot read properties of undefined (reading 'channels') on the line : const channel2up22 = guild.channels.cache.get('935549530210983976');

虽然我看了文档，但我做不到，我也指定我的公会ID和我的频道ID是正确的，我在发布问题之前检查过。

你有办法纠正这个错误吗？提前致谢！

const Discord = require("discord.js");
const Client = new Discord.Client;

const fs = require('fs')

const guild = Client.guilds.cache.get('925830522138148976');

const channel2up22 = guild.channels.cache.get('935549530210983976');

const userCoin = JSON.parse(fs.readFileSync('Storage/userCoin.json', 'utf-8'));

// placing the function outside of a listener and can be called at anytime

        .setTitle("Wild Gift  ! | GuinGame - v2.0 ")

// you want to avoid nesting listeners if at all possible

        if (reaction.emoji.name === '' && user.id === "338621907161317387") {
           // only lets one user react

            while (Magic09 <= 10) {
                userCoin[user.id].CoinsAmount;
                Magic09++;

            fs.writeFile('Storage/userCoin.json', JSON.stringify(userCoin), (err) => {

问题是您试图在 client 准备好之前获取公会和频道。公会和频道缓存仅在发出就绪事件后可用，就像在几乎所有其他类型的 Discord 结构上检索信息时一样。如您所见，下面的代码片段在 ready 事件处理程序之外，这将导致 guild 始终为 undefined（作为您得到的错误状态）：

const guild = Client.guilds.cache.get('925830522138148976');
const channel2up22 = guild.channels.cache.get('935549530210983976');

相反，将那段代码移到 doSomething 函数本身，这样您的代码只会在客户端准备就绪后才尝试检索公会和频道。当然，假设您仅在客户端准备就绪后调用 doSomething 函数（如果您从 ready 处理程序或其他几个事件处理程序调用它，则为真）。这是一个例子：

function doSomething() {
    const guild = Client.guilds.cache.get('925830522138148976');
    const channel2up22 = guild.channels.cache.get('935549530210983976');

    const Embed = new Discord.MessageEmbed()
        .setTitle("Wild Gift  ! | GuinGame - v2.0 ")
        .setColor('#caabd0')
        .setDescription("Be the **first** to react ``''`` to this message to win **10!**")
        .setThumbnail("https://media.giphy.com/media/Jv1Xu8EBCOynpoGBwd/giphy.gif")
        .setFooter({
            text: " GuinbearBot  |   Guinbeargang.io"
        })
        .setTimestamp()
    channel2up22.send({
        embeds: [Embed]
    }).then(message => {
        message.react('');
    }).catch(console.error);
}

这个问题还有一些其他可能的解决方案，但这个很可能是最简单的解决方案。

更新

感谢 @Cannicide，我设法正确修改了我的代码，使其 returns 每 5 秒发送一条消息而不会崩溃。

const Discord = require("discord.js");
const Client = new Discord.Client;
const fs = require('fs')
const userCoin = JSON.parse(fs.readFileSync('Storage/userCoin.json', 'utf-8'));

function doSomething() {
    const guild = Client.guilds.cache.get('925830522138148976');
    const channel2up22 = guild.channels.cache.get('966206342740181012');

    let Embed = new Discord.MessageEmbed()
        .setTitle("Wild Gift  ! | GuinGame - v2.0 ")
        .setColor('#caabd0')
        .setDescription("Be the **first** to react ``''`` to this message to win **10 !**")
        .setThumbnail("https://media.giphy.com/media/Jv1Xu8EBCOynpoGBwd/giphy.gif")
        .setFooter(text=" GuinbearBot  |   Guinbeargang.io")
        .setTimestamp()
    channel2up22.send(Embed).then(message => {
        message.react('');
    }).catch(console.error);
}

Client.on('messageReactionAdd', (reaction, user) => {
    const guild = Client.guilds.cache.get('925830522138148976');
    const channel2up22 = guild.channels.cache.get('966206342740181012');
    if (reaction.message.channel.id == channel2up22) {
    if (reaction.emoji.name == '' && user.id !== "936254253285146635") {
        reaction.message.delete();
        var Magic09 = 1;
        while (Magic09 <= 10) {
            userCoin[user.id].CoinsAmount;
            Magic09++;
        }
        fs.writeFile('Storage/userCoin.json', JSON.stringify(userCoin), (err) => {
            if (err) console.error(err);
        })
        let Embed = new Discord.MessageEmbed()
            .setTitle("Wild Gift  ! | GuinGame - v2.0 ")
            .setColor('#caabd0')
            .setDescription(`${user} has won the **Wild Gift  !**`)
            .setThumbnail("https://media.giphy.com/media/Jv1Xu8EBCOynpoGBwd/giphy.gif")
            .setFooter(text=" GuinbearBot  |   Guinbeargang.io")
            .setTimestamp()
        channel2up22.send(Embed)
        
    }
}
});

Client.on('ready', () => {
    setInterval(doSomething, 5000)
});
