在这种情况下如何让 Discord bot 编辑嵌入消息？

Question

现在，我有一个 Discord 机器人，可以为游戏设置“注册”。

我正在寻找的是让用户能够发送消息“+join (class)”来注册一个插槽。因此，如果我说“+join Soldier”，它会将我的名字放在插槽中，如下所示：

如果所有名额都已满或工作人员键入“+close”，它将关闭当前游戏的注册。我知道我必须使用 .edit 函数将嵌入替换为相同的新嵌入，但用户名已放入插槽中，但我真的不知道该怎么做，特别是因为这涉及两个单独的 javascript 文件。我真的很感激所有的帮助。太感谢了！ :)

JoinCommand.js：

const BaseCommand = require('../../utils/structures/BaseCommand');
const Discord = require('discord.js');

module.exports = class JoinCommand extends BaseCommand {
  constructor() {
    super('join', 'member', []);
  }

  run(client, message, args) {
    const mvmClass = args[0];
    message.channel.send(message.author.toString() + ` joined as ${mvmClass}!`);
  }
}

Answer 1

您在https://discord.js.org 页面上使用<Message>.edit()。

例子：

let text = "Hello world!";
message.channel.send(text).then(msg=> {
    text = text.replace("world", "my friend") // "Hello my friend!"
    msg.edit(text)
}

或

let msg = message.channel.send("Hello world");
msg.edit("Hello my friend");

请再次阅读文档！或者只是先谷歌它。
