不和谐机器人记录器

Question

有人可以帮我让那个脚本工作吗？我猜它没有更新到最新的 Discord API。

我只需要三样东西：一个带有昵称更改、用户名更改和头像更改的记录器。

当有新人加入时，我已经通过角色更改和欢迎信息让自己成为工作记录器，但这三个似乎被打破了。

bot.on('guildMemberUpdate', function(guild, oldMember, newMember) {

    //declare changes
    var Changes = {
        unknown: 0,
        addedRole: 1,
        removedRole: 2,
        username: 3,
        nickname: 4,
        avatar: 5
    };
    var change = Changes.unknown;

    //check if username changed
    if (newMember.user.username != oldMember.user.username)
        change = Changes.username;

    //check if nickname changed
    if (newMember.nickname != oldMember.nickname)
        change = Changes.nickname;

    //check if avatar changed
    if (newMember.user.avatarURL != oldMember.user.avatarURL)
        change = Changes.avatar;

    //log to console
    switch (change) {
        case Changes.unknown:
            console.log('[' + guild.name + '][UPDUSR] ' + newMember.user.username + '#' + newMember.user.discriminator);
            break;


        case Changes.username:
            console.log('[' + guild.name + '][UPDUSRNM] ' + oldMember.user.username + '#' + oldMember.user.discriminator +
                ' is now ' + newMember.user.username + '#' + newMember.user.discriminator);
            break;
        case Changes.nickname:
            console.log('[' + guild.name + '][UPDUSRNK] ' + newMember.user.username + '#' + newMember.user.discriminator +
                (oldMember.nickname != null ? ' (' + oldMember.nickname + ')' : '') +
                (newMember.nickname != null ? ' is now ' + newMember.nickname : ' no longer has a nickname.'));
            break;
        case Changes.avatar:
            console.log('[' + guild.name + '][UPDAVT] ' + newMember.user.username + '#' + newMember.user.discriminator);
            break;
    }

    //post in the guild's log channel
    var log = guild.channels.find('name', CHANNEL);
    if (log != null) {
        switch (change) {
            case Changes.unknown:
                log.sendMessage('**[User Update]** ' + newMember);
                break;


            case Changes.username:
                log.sendMessage('**[User Username Changed]** ' + newMember + ': Username changed from ' +
                    oldMember.user.username + '#' + oldMember.user.discriminator + ' to ' +
                    newMember.user.username + '#' + newMember.user.discriminator);
                break;
            case Changes.nickname:
                log.sendMessage('**[User Nickname Changed]** ' + newMember + ': ' +
                    (oldMember.nickname != null ? 'Changed nickname from ' + oldMember.nickname +
                        +newMember.nickname : 'Set nickname') + ' to ' +
                    (newMember.nickname != null ? newMember.nickname + '.' : 'original username.'));
                break;
            case Changes.avatar:
                log.sendMessage('**[User Avatar Changed]** ' + newMember);
                break;
        }
    }

});

Answer 1

以下行导致您的程序出错：

    var log = guild.channels.find('name', CHANNEL);

在discord.js v12中，你需要使用一个函数并使用.cache.

这里是更正的版本：

    var log = guild.channels.cache.find(c => c.name == CHANNEL);

Answer 2

有几个问题：

1. guildMemberUpdate 事件仅传递两个参数：oldMember 和 newMember。如您的代码所示，它不会传递 guild 参数。
2. 由于没有传递guild参数，您需要将所有对guild的引用更改为newMember.guild。
3. guild.channels 现在需要在末尾附加 .cache：guild.channels.cache。如需更多信息，请阅读Discord.js migration guide。
4. Discord.Collection().find() 方法现在只接受一个函数。
5. .sendMessage() 需要替换为 .send()。
6. .avatarURL 需要替换为 .displayAvatarURL()。

旁注：为什么不使用newMember.user.tag 而不是newMember.user.username + '#' + newMember.user.discriminator？

这是修改后的代码：

bot.on('guildMemberUpdate', function(oldMember, newMember) {

    //declare changes
    var Changes = {
        unknown: 0,
        addedRole: 1,
        removedRole: 2,
        username: 3,
        nickname: 4,
        avatar: 5
    };
    var change = Changes.unknown;

    //check if username changed
    if (newMember.user.username !== oldMember.user.username)
        change = Changes.username;

    //check if nickname changed
    if (newMember.nickname !== oldMember.nickname)
        change = Changes.nickname;

    //check if avatar changed
    if (newMember.user.displayAvatarURL() !== oldMember.user.displayAvatarURL())
        change = Changes.avatar;

    //log to console
    switch (change) {
        case Changes.unknown:
            console.log('[' + newMember.guild.name + '][UPDUSR] ' + newMember.user.username + '#' + newMember.user.discriminator);
            break;


        case Changes.username:
            console.log('[' + newMember.guild.name + '][UPDUSRNM] ' + oldMember.user.username + '#' + oldMember.user.discriminator +
                ' is now ' + newMember.user.username + '#' + newMember.user.discriminator);
            break;
        case Changes.nickname:
            console.log('[' + newMember.guild.name + '][UPDUSRNK] ' + newMember.user.username + '#' + newMember.user.discriminator +
                (oldMember.nickname != null ? ' (' + oldMember.nickname + ')' : '') +
                (newMember.nickname != null ? ' is now ' + newMember.nickname : ' no longer has a nickname.'));
            break;
        case Changes.avatar:
            console.log('[' + newMember.guild.name + '][UPDAVT] ' + newMember.user.username + '#' + newMember.user.discriminator);
            break;
    }

    //post in the guild's log channel
    var log = newMember.guild.channels.cache.find(channel => channel.name === CHANNEL);
    if (log) {
        switch (change) {
            case Changes.unknown:
                log.send('**[User Update]** ' + newMember);
                break;


            case Changes.username:
                log.send('**[User Username Changed]** ' + newMember + ': Username changed from ' +
                    oldMember.user.username + '#' + oldMember.user.discriminator + ' to ' +
                    newMember.user.username + '#' + newMember.user.discriminator);
                break;
            case Changes.nickname:
                log.send('**[User Nickname Changed]** ' + newMember + ': ' +
                    (oldMember.nickname != null ? 'Changed nickname from ' + oldMember.nickname +
                        +newMember.nickname : 'Set nickname') + ' to ' +
                    (newMember.nickname != null ? newMember.nickname + '.' : 'original username.'));
                break;
            case Changes.avatar:
                log.send('**[User Avatar Changed]** ' + newMember);
                break;
        }
    }

});
