嗨，我想为我的投票数增加一个比例。目前，我正在制作音乐模块。音乐命令（例如暂停，跳过，音量等）基于用户给出的反应（表情符号）。
当前跳过一首歌曲需要5个反应。问题之一是有时在语音通道中一次听音乐的次数少于五次，因此无法跳过歌曲。
因此，我需要实现某种比例，例如，如果语音通道中有2位成员，那么例如2次跳过将跳过该歌曲。我有点不确定如何实现它，但我还是同意了。
更具体地说，我正在看这一行：
if control == 'skip':
skip = await channel.send(f':poop: **{user.name}** voted to skip **{source.title}**. **{react.count}/5** voted.', delete_after=8)
if react.count >= 5: # bot counts as 1 reaction.
vc.stop()
await channel.send('**Skipping song...**', delete_after=5)
这是我正在使用的完整代码：

好的，你可以做这样的事情
@Query("SELECT offer FROM OfferEntity offer " +
" JOIN offer.placeOwnership AS owner " +
" JOIN owner.place AS place " +
"WHERE " +
" place.id = :placeId AND " +
" offer.offerDate = to_date(to_char(:date, 'yyyy-MM-dd')) ")
List<OfferEntity> getAllForDate(@Param("placeId") Long placeId, @Param("date") Date date);
只有在语音频道中超过一半或恰好一半的人投票跳过时，它才会跳过歌曲
您可以稍后调整所需的比例
答案 1 :(得分：0)
少于5个成员时，允许所有成员共同投票的一种简单方法是使用类似的方法：
votes_needed_to_skip = min(current_listener_count, 5)
if react.count >= votes_needed_to_skip: # bot counts as 1 reaction.
如果您希望3/4个或五个人（以先到者为准）能够跳过它（请注意，使用这种方法，六个人中的3/4是四个人，因此只需要四张选票即可）总人数为六个，即使人数超过五个）：
votes_needed_to_skip = min(current_listener_count*3//4, 5)
if react.count >= votes_needed_to_skip: # bot counts as 1 reaction.
