有什么解决办法吗？我自己一个也找不到。 ';help' 是获取所有命令的常规命令。子命令将是 ';help userinfo'、';help rules' 等。我在 discord.py discord 服务器中询问过，我也尝试过使用官方 Python discord 服务器寻求帮助。但似乎没有任何效果。有什么修复吗？ 任何帮助都会很棒:)
【问题讨论】：
你为什么不使用内置的子命令支持？为什么要使用 if 语句？继承默认的帮助命令不是更容易吗？ @ŁukaszKwieciński 该死。不知道那是一回事 如果您需要嵌入帮助，请查看 this 示例 【参考方案1】：您可以使用 commands.HelpCommand 或 commands.MinimalHelpCommand
例如：
class MyHelpCommand(commands.MinimalHelpCommand):
def get_command_signature(self, command):
return '0.clean_prefix1.qualified_name 1.signature'.format(self, command)
class MyCog(commands.Cog):
def __init__(self, bot):
self._original_help_command = bot.help_command
bot.help_command = MyHelpCommand()
bot.help_command.cog = self
def cog_unload(self):
self.bot.help_command = self._original_help_command
Help command docs
RoboDanny's Help command
注意： 我使用的示例取自 discord.py discord 服务器。
