如何在 discord.py 中创建计时器命令？

Question

我想做一个定时器命令。

    @commands.command()
    async def timer(self, ctx, seconds):
        try:
            secondint = int(seconds)
            if secondint > 300:
                await ctx.send("I dont think im allowed to do go above 300 seconds.")
                raise BaseException
            if secondint < 0 or secondint == 0:
                await ctx.send("I dont think im allowed to do negatives")
                raise BaseException
            message = await ctx.send("Timer: " + seconds)
            while True:
                secondint = secondint - 1
                if secondint == 0:
                    await message.edit(new_content=("Ended!"))
                    break
                await message.edit(new_content=("Timer: {0}".format(secondint)))
                await asyncio.sleep(1)
            await ctx.send(ctx.message.author.mention + " Your countdown Has ended!")
        except ValueError:
            await ctx.send("Must be a number!")

我试过了，但这不起作用，它不会像我想要的那样编​​辑消息并且没有错误。

它不会编辑消息，因为 new_content 不是 Message.edit() 方法参数。
它只有：content / embed / suppress / delete_after / allowed_mentions。

你要找的是content:

@commands.command()
async def timer(self, ctx, seconds):
    try:
        secondint = int(seconds)
        if secondint > 300:
            await ctx.send("I dont think im allowed to do go above 300 seconds.")
            raise BaseException
        if secondint <= 0:
            await ctx.send("I dont think im allowed to do negatives")
            raise BaseException
        message = await ctx.send("Timer: {seconds}")
        while True:
            secondint -= 1
            if secondint == 0:
                await message.edit(content="Ended!")
                break
            await message.edit(content=f"Timer: {secondint}")
            await asyncio.sleep(1)
        await ctx.send(f"{ctx.author.mention} Your countdown Has ended!")
    except ValueError:
        await ctx.send("Must be a number!")

唯一有效的方法是如果你做这样的事情

import asyncio

@client.command()
async def count(ctx, number:int):
    try:
        if number < 0:
            await ctx.send('number cant be a negative')
        elif number > 300:
            await ctx.send('number must be under 300')
        else:
            message = await ctx.send(number)
            while number != 0:
                number -= 1
                await message.edit(content=number)
                await asyncio.sleep(1)
            await message.edit(content='Ended!')

    except ValueError:
        await ctx.send('time was not a number')

好的，下面是上面标有绿色复选标记的脚本的修改版本。我进行了一些更改以使其更加用户友好（单位转换器将例如“5m”转换为 300 秒，而不是显示“90 秒”，而是显示“1 分 30 秒”等），并且更容易供大众使用。我不擅长编码，我处于初学者水平，但我希望这会有所帮助！

@commands.command()
async def timer(self, ctx, timeInput):
    try:
        try:
            time = int(timeInput)
        except:
            convertTimeList = {'s':1, 'm':60, 'h':3600, 'd':86400, 'S':1, 'M':60, 'H':3600, 'D':86400}
            time = int(timeInput[:-1]) * convertTimeList[timeInput[-1]]
        if time > 86400:
            await ctx.send("I can\'t do timers over a day long")
            return
        if time <= 0:
            await ctx.send("Timers don\'t go into negatives :/")
            return
        if time >= 3600:
            message = await ctx.send(f"Timer: {time//3600} hours {time%3600//60} minutes {time%60} seconds")
        elif time >= 60:
            message = await ctx.send(f"Timer: {time//60} minutes {time%60} seconds")
        elif time < 60:
            message = await ctx.send(f"Timer: {time} seconds")
        while True:
            try:
                await asyncio.sleep(5)
                time -= 5
                if time >= 3600:
                    await message.edit(content=f"Timer: {time//3600} hours {time %3600//60} minutes {time%60} seconds")
                elif time >= 60:
                    await message.edit(content=f"Timer: {time//60} minutes {time%60} seconds")
                elif time < 60:
                    await message.edit(content=f"Timer: {time} seconds")
                if time <= 0:
                    await message.edit(content="Ended!")
                    await ctx.send(f"{ctx.author.mention} Your countdown Has ended!")
                    break
            except:
                break
    except:
        await ctx.send(f"Alright, first you gotta let me know how I\'m gonna time **{timeInput}**....")
