如何删除所有角色并在discord bot上添加一个角色，然后删除添加的角色并还原以前的角色 [英] How to remove all roles and add one role on discord bot, and then remove the added role and restore previous roles

问题描述

我有一段代码供不和谐的bot删除特定的命名角色，并在特定的时间内添加一个名为"muted"的角色.基本上，服务器只能具有3个角色，一个可以发出命令，一个具有正常权限的正常"等级，然后是一个静音"角色.我的代码专门删除了普通角色，并添加了静音角色，因此他们没有任何权限.

I have a line of code for a discord bot to remove a specific named role and add a role named "muted" for a specific amount of time. Basically, the server can only have 3 roles, one that can issue the command, a "normal" rank with normal permissions, and then a "muted" role. and my code specifically removed the normal role and adds the muted role so they don't have any permissions.

好吧，我将我的机器人添加到了具有3个以上角色的另一台服务器上，我决定给每个人正常的角色，并且也将其设为静音角色.当我运行该命令时，它可以工作，但是由于人们还有其他角色，因此即使将静音角色放在首位，它也可以继续讲话.

Well I added my bot onto another server with more than 3 roles, I decided to give everyone the normal role and also make the muted role. when I run the command, it works, but since the people have other roles, it allows then to continue speaking even though the muted role is at the top priority.

我的问题是，有一些代码可以删除所有角色并添加静音角色.静音期结束后，静音角色将被删除并恢复其先前的角色吗?这是我的代码如下:

My questions is that is there some code where I can just remove all their roles and add the muted role. and when the muted period is over, the muted role is removed and their previous roles are restored? here is my code below:

 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;

推荐答案

最简单的方法是从用户那里获取角色列表，清除其角色，然后申请Muted角色.然后，您想缓存他们以前的角色，或者甚至将数据存储在数据库中，以防机器人崩溃，这样一来，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.

The simplest way to do this would be to get the list of roles from the user, clear their roles, and then apply for the Muted role. You'd then want to cache their previous roles or even store the data in a database in case the bot goes down, that way once restarted you could fetch the data and continue where you left off.

这是我即时编写的一个简单示例.由于我的方法只是用于快速演示，因此您可能希望缓存角色的方式与我的方式有所不同，因此我强烈建议将数据保存到数据库或什至是.json文件之类.

Here's a quick example I wrote on the fly. You probably want to cache the roles a bit differently than the way I did since my method was just for a quick demo, and i highly recommend saving the data to a database or even something like a .json file.

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)
}

在您的情况下，它看起来像这样:

In your case, it would look something like this:

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;
