Any way to use command cooldowns for slash commands?

[brotherelric]

I would want a command I have in a slash cog to not be replying every time the user wants to, I would want a 30 second cooldown so the bot doesn't have to run many commands at once from various users.

Cooldown support for slashcommands is currently limited to the preview version

from discord.ext import commands

# the `1` will indicate how often the command can be used before a cooldown is "activated"
# `30` is the amount of seconds for cooldown 
@slash_command(...)
@commands.cooldown(1, 30, commands.BucketType.user)
async def my_command(self, ctx):
   ...

This doesn't seem to work for me: no errors, command works perfectly fine..

I'm really sorry for that, seems that cooldowns can't work on slashcommands because of a missing attribute (interactions don't have a created_at attribute).
I'll try to add something for cooldown on slashcommads

[brotherelric]

Sure! I'll be waiting.

I added cooldown support to the preview version so if you want to use cooldowns you will either have to switch to the preview version or wait until it gets released

I've updated my original answer

Sorry for the inconvenience

Downloaded the preview. Few things to note:
-It tells me @slash_cog is deprecated, @slash_command worked fine so no problems
-I cannot send embeds. "discord.errors.HTTPException: 400 Bad Request (error code: 50006): Cannot send an empty message"
-Cooldowns with @commands.cooldown() doesn't work.

You have to place the cooldown decorator before the slash_command decorator

I'll fix the embed issue, thank you for reporting that

[brotherelric]

Oh, that worked! Thank you!
Is there a way to send an specific message when a specific command is on cooldown? Different message when on-cooldown depending on the command.

yes, I added something for this, you can do this by

class MyCog(commands.Cog):
    @slash_command(...)
    @commands.cooldown(...)
    async def my_command(self, ctx):
        ...
    @my_command.cooldown
    async def my_cooldown_handler(self, ctx, cooldown_exception):
        await ctx.send(cooldown_exception) # just an example

cooldown_exception is of type discord.ext.commands.errors.CommandOnCooldown
