Discord.py不允许每个命令进行多次冷却检查，因此您必须使用自定义冷却处理程序。
这是一个具有基本冷却时间的基本命令：
@client.command()
@commands.cooldown(5, 57600, commands.BucketType.user)
async def ping(ctx)
await ctx.send("pong")
因此，基本上，当用户使用命令的前缀(例如"！k"(时；ping"；机器人程序将发送"；乒乓球"聊天。这是一个非常基本的命令，但接下来是冷却装饰器。冷却后：
@commands.cooldown(5, 57600, commands.BucketType.user)
我们可以看出，该命令可以在57600秒(16小时(之间使用5次，但如果我希望一个命令每16小时只使用5次并且每次使用该命令之间还有另一个冷却时间，该怎么办？让我解释一下。。。
每16小时可以使用该命令5次
但当你使用该命令时，你必须等待1个小时才能再次使用
这样，你就不能在一分钟内直接使用命令5次
把它想象成一棵每小时长一个苹果，但每天只长5个苹果的树。。。如何防止用户直接使用该命令5次？谢谢-
