【问题描述】：

更新

我已经更新了当前为我工作的代码，它现在将创建频道，然后检查频道是否已创建。它只允许 1 个用户创建一个频道，您将无法作为同一用户创建 T5 频道和 T4 频道。

谢谢大家，希望大家圣诞快乐。

【参考方案1】：

您应该使用reaction collector。

这些工作与消息收集器非常相似，除了你 将它们应用于消息而不是通道。以下是一个 取自文档的示例，变量稍好一些 用于澄清的名称。过滤器将检查 ? 表情符号 - in 特别是默认肤色，所以要小心。它还将 检查做出反应的人是否与作者共享相同的 id 收集器被分配到的原始消息。

const filter = (reaction, user) => 
    return reaction.emoji.name === '?' && user.id === message.author.id;
;

const collector = message.createReactionCollector(filter,  time: 15000 );

collector.on('collect', (reaction, user) => 
    console.log(`Collected $reaction.emoji.name from $user.tag`);
);

collector.on('end', collected => 
    console.log(`Collected $collected.size items`);
);

阅读它的文档here。

我还想知道是否可以将每个对特定角色做出反应的用户随机配对。

collected 属性对于这项任务应该很方便。 至于向GuildMember 添加角色/角色，请使用add 方法。了解如何将角色添加到成员 here。

【参考方案2】：

如果您想获得消息的所有反应，如果您已经拥有消息对象，则可以使用message 上的reactions 属性。这将返回一个您可以使用的ReactionManager。
