Discord.py 每个用户的冷却时间不同

问题描述

如果用户不在列表中，我想创建一个只有冷却时间的命令这是我的代码:

I want to make a command that have only a cooldown if the user is not in a list This is my code:

@commands.command(name='cooldown')
@commands.cooldown(1, 300, commands.BucketType.user)
async def cdown(self, ctx):
  await ctx.send("Executed")

应该是这样的:

@commands.command(name='cooldown')
if not user in no_cooldown_users:
  @commands.cooldown(1, 300, commands.BucketType.user)
async def cdown(self, ctx):
  await ctx.send("Executed")

有没有可能做这个而不是使用配置?

Is there any possibility to make this instead of using a config?

推荐答案

你要自定义冷却时间，这里举个很简单的例子

You have to make a custom cooldown, here a very simple example

from discord.ext import commands

class CustomCooldown:
    def __init__(self, rate, per, alter_rate, alter_per, bucket, *, elements):
        self.elements = elements
        # Default mapping is the default cooldown
        self.default_mapping = commands.CooldownMapping.from_cooldown(rate, per, bucket)
        # Alter mapping is the alternative cooldown
        self.alter_mapping = commands.CooldownMapping.from_cooldown(alter_rate, alter_per, bucket)
        # Copy of the original BucketType
        self._bucket_type = bucket

    def __call__(self, ctx):
        key = self.alter_mapping._bucket_key(ctx.message)

        if self._bucket_type is commands.BucketType.member: # `BucketType.member` returns a tuple
            key = key[1] # The second (last) value is the member ID, the first one is the guild ID

        if key in self.elements:
            # If the key is in the elements, the bucket will be taken from the alternative cooldown
            bucket = self.alter_mapping.get_bucket(ctx.message)
        else:
            # If not, from the default cooldown
            bucket = self.default_mapping.get_bucket(ctx.message)

        # Getting the ratelimit left (can be None)
        retry_after = bucket.update_rate_limit()

        if retry_after: # If the command is on cooldown, raising the error
            raise commands.CommandOnCooldown(bucket, retry_after)
        return True

使用它:

@command.commands()
@commands.check(CustomCooldown(1, 300, 1, 0, commands.BucketType.user, elements=[list of ids]))
async def foo(self, ctx):
    ...

前两个值是默认冷却时间的速率和时间，接下来的两个值是特殊"冷却时间.冷却.接下来是桶类型，最后是元素列表(id).

The first two values are the rate and per of the default cooldown, the next two values are for the "special" cooldown. Next there's the bucket type, and lastly the list of elements (ids).

您还可以使用此方法为每个角色/公会/类别/频道提供不同的冷却时间...

You can also use this method for different cooldown per roles/guilds/categories/channels...
