javascript - 如何在discord bot上删除所有 Angular 色并添加一个 Angular 色，然后删除添加的 Angular 色并恢复以前的 Angular 色

Question

我有一行不和谐机器人的代码，用于删除特定的命名 Angular 色并添加一个名为“静音”的 Angular 色一段特定的时间。基本上，服务器只能有 3 个 Angular 色，一个可以发出命令，一个具有正常权限的“普通” Angular 色，然后是一个“静音” Angular 色。我的代码专门删除了正常 Angular 色并添加了静音 Angular 色，因此他们没有任何权限。

好吧，我将我的机器人添加到另一台具有超过 3 个 Angular 色的服务器上，我决定为每个人提供正常 Angular 色，并设置静音 Angular 色。当我运行该命令时，它起作用了，但由于人们有其他 Angular 色，因此即使静音 Angular 色处于最高优先级，它也允许继续讲话。

我的问题是，是否有一些代码可以删除他们的所有 Angular 色并添加静音 Angular 色。当禁言期结束后，禁言 Angular 色被解除，恢复原来的 Angular 色？下面是我的代码:

 case 'mute':

    if(!message.member.roles.cache.find(r => r.name === "Admin")) return message.channel.send('You dont have permissions to do that you clown')

    let person = message.guild.member(message.mentions.users.first() || message.guild.members.get(args[1]))
    if(!person) return message.reply("User Doesn't Exist");

    let mainrole = message.guild.roles.cache.find(role => role.name == "normal");
    let muterole = message.guild.roles.cache.find(role => role.name == "muted");

    if(!muterole) return message.reply("Role Doesn't Exist");

    let time = args[2];

    if(!time){
        return message.reply("How Long?");
    }

    person.roles.remove(mainrole.id);
    person.roles.add(muterole.id);

    message.channel.send(`@${person.user.tag} has now been muted for ${ms(ms(time))}`);

    setTimeout(function(){
        person.roles.add(mainrole.id);
        person.roles.remove(muterole.id);
        message.channel.send(`@${person.user.tag} has now been unmuted`)
    }, ms(time));
        break;
    case 'help':
        const embed2 = new MessageEmbed()
        .setTitle("How To Get Commands")
        .setColor(0x00fff7)
        .setDescription("Do /commands to get the list of commands");

        message.author.send(embed2);
        break;

最简单的方法是从用户处获取 Angular 色列表，清除其 Angular 色，然后申请静音 Angular 色。然后，您需要缓存他们以前的 Angular 色，甚至将数据存储在数据库中，以防机器人出现故障，这样一旦重新启动，您就可以获取数据并从上次中断的地方继续。

这是我即时编写的一个简单示例。您可能希望缓存 Angular 色的方式与我的方式略有不同，因为我的方法只是为了快速演示，我强烈建议将数据保存到数据库，甚至保存到 .json 文件之类的文件中。

let cachedUserRoles = {};

function addMutedRole(guildId, userId, roleId) {
    //Get the guild the user is apart of
    let guild = client.guilds.get(guildId);
    //Specify the user from the guild
    let guildMember = guild.members.get(userId);

    //Cache the users existing roles so we can restore them later
    cachedUserRoles[userId] = guildMember.roles.cache
    //Remove all roles from user
    guildMember.roles.set([])
        //Add the muted role after all roles have been removed with an array of the single role ID
        .then(member => member.roles.add([roleId]))
        //Catch and report any errors that might happen
        .catch(console.error)
}

function restoreRoles(guildId, userId) {
    //Get the guild the user is apart of
    let guild = client.guilds.get(guildId);
    //Specify the user from the guild
    let guildMember = guild.members.get(userId);
    //Get and set the user's previouse roles from cachedUserRoles and error log if anything goes wrong
    guildMember.roles.set(cachedUserRoles[userId]).catch(console.error)
}

就您而言，它看起来像这样:

case 'mute':
        if(!message.member.roles.cache.find(r => r.name === "Admin")) return message.channel.send('You dont have permissions to do that you clown')

        let person = message.guild.member(message.mentions.users.first() || message.guild.members.get(args[1]))
        if(!person) return message.reply("User Doesn't Exist");

        let muterole = message.guild.roles.cache.find(role => role.name == "muted");

        if(!muterole) return message.reply("Role Doesn't Exist");

        let time = args[2];

        if(!time){
            return message.reply("How Long?");
        }

        //Cache their already existing roles
        cachedUserRoles[person.id] = person.roles.cache;
        //Set their roles to an empty array to clear them, then add the muted role once all roles were removed successfully
        person.roles.set([]).then(member => member.roles.add(muterole)).catch(console.error);

        message.channel.send(`@${person.user.tag} has now been muted for ${ms(ms(time))}`);

        setTimeout(function(){
            //Grab their existing roles and set them back to the user, we wont need to remove the muted role since setting the roles would override all existing ones already
            person.roles.set(cachedUserRoles[person.id]).catch(console.error)
            message.channel.send(`@${person.user.tag} has now been unmuted`)
        }, ms(time));
        break;
    case 'help':
        const embed2 = new MessageEmbed()
            .setTitle("How To Get Commands")
            .setColor(0x00fff7)
            .setDescription("Do /commands to get the list of commands");

        message.author.send(embed2);
        break;
