Discord JDA-getMembers（）不工作，仍返回0

Question

这就是我的代码的外观：

public void onGuildVoiceJoin(GuildVoiceJoinEvent event) {
 
    String channelId = event.getChannelJoined().getId();
     
    if (channelId.equals("904375329764814870")) {
         
        Member member = event.getMember();
        String memberName = event.getMember().getEffectiveName();
        Category category = event.getGuild().getCategoryById("904364634507706468");
         
        event.getGuild().createVoiceChannel("Coaching " + memberName).setParent(category).complete();
         
        List<VoiceChannel> channelList = event.getGuild().getVoiceChannelsByName("Coaching " + memberName, true);
        VoiceChannel channel = channelList.get(0);
      
        event.getGuild().moveVoiceMember(member, channel).queue();
         
         
        while (true){
                
            event.getGuild().getTextChannelById("904364671467929610").sendMessage(
                 
               "Number of people currently on the channel : " + channel.getMembers().size()
         
            ).queue();
             
            wait(3000);
                     
        }

我的目标是得到目前频道内的人数。

我认为getMembers（）方法是个好方法，但它不起作用

我用无限的时间来观察这个通道。getMembers（）。当我加入/离开频道时，size（）会改变，但它仍然返回0。

我怎样才能解决这个问题？并获得正确的人数在通道内作为回报。

我的代码的最终目标是在频道没有用户时删除该频道

这可以通过检查GuildVoiceUpdateEvents中的成员计数来实现：

public void onGuildVoiceUpdate(GuildVoiceUpdateEvent event) {
  if (channel.getName().startsWith("Coaching ")) { // check if name matches the desired name
    if (channel.getMembers().isEmpty()) { // check if channel is empty
      channel.delete().queue(); // delete channel
    }
  } 
}
