Discord.j - 函数奇怪地为空

Question

这个问题与另一个问题有关。如果你想知道我问这个的原因，请查看this question。

我正在开发一个机器人，它应该获得一个包含具有特定角色的成员的集合。但是在测试和仔细检查角色名称并确保我在服务器中而不是在 DM 中测试机器人之后，集合始终是空的且无法使用（没有它程序无法运行）。

const eventMembers = message.guild.members.cache.filter(m =>
      m.roles.cache.some(r => r.name === "event")
   );

const connectedMembers = eventMembers.members.filter(m => {
      return voiceChannel.members.has(m.id)
   });
console.log(connectedMembers);

如果有人有提示或解决方案，我会接受

Answer 1

你忘了返回 :)

const eventMembers = message.guild.members.cache.filter(m => {
    return  m.roles.cache.some(r => r.name === "event")
      });

或

const eventMembers = message.guild.members.cache.filter(m => m.roles.cache.some(r => r.name === "event"));

您可以检查具有此名称的角色是否存在：

let role = message.guild.roles.cache.find(role => role.name === 'event')
if (role) {
    console.log('ok')
} else {
    console.log('No role found with this nickname')
}

V2

const eventMembers = message.guild.members.cache.filter(m => {
    return  m.roles.cache.some(r => r.name === "event") && m.voice && m.voice.channelID === message.member.voice.channelID
   });

或

const eventMembers = message.guild.members.cache.filter(m => m.roles.cache.some(r => r.name === "event") && m.voice && m.voice.channelID === message.member.voice.channelID)

V3 :D

bot.on('message', message => {
    if(message.content === '!test') {
        if(!message.member.voice.channel) return message.reply('You need joinVoiceChannel for use this command');
        let targetRole = message.guild.roles.cache.find(role => role.name === 'event')
        if (!targetRole) return message.reply('Can`t find a role');
        let eventMembersNotInVoice = targetRole.members.filter(member => member.voice.channelID !== message.member.voice.channelID)
        console.log(eventMembersNotInVoice.size)
    }
});
