Discord.py 如何制作掷骰子命令

大家好，我正在用 Python 编写一个 Discord 机器人，我想编写一个掷骰子命令。我认为我做错了什么。这是代码：

@client.command()
async def rolldice(ctx):
    dice4 = ["1","2","3","4"]
    dice6 = ["1","2","3","4","5","6"]
    dice8 = ["1","2","3","4","5","6","7","8"]
    dice10 = ["1","2","3","4","5","6","7","8","9","10"]
    dice12 = ["1","2","3","4","5","6","7","8","9","10","11","12"]
    dice20 = ["1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20"]
    
    message = await ctx.send("Choose a number:\n**4**, **6**, **8**, **10**, **12**, **20** ")
    
    def check4(m):
        return m.author == ctx.author and m.content == "4"

    try:
        await client.wait_for('message', check=check4, timeout=30.0)
        coming = await ctx.send("Here it comes...")
        time.sleep(1)
        await coming.delete()
        await ctx.send(f"**{random.choice(dice4)}**")
        
    except asyncio.TimeoutError:
        await message.delete()
        await ctx.send("Procces has been canceled because you didn't answer in **30** second!")

    def check6(m):
        return m.author == ctx.author and m.content == "6"

    try:
        await client.wait_for('message', check=check6, timeout=30.0)
        coming = await ctx.send("Here it comes...")
        time.sleep(1)
        await coming.delete()
        await ctx.send(f"**{random.choice(dice6)}**")
        
    except asyncio.TimeoutError:
        await message.delete()
        await ctx.send("Procces has been canceled because you didn't answer in **30** second!")
    
    def check8(m):
        return m.author == ctx.author and m.content == "8"

    try:
        await client.wait_for('message', check=check8, timeout=30.0)
        coming = await ctx.send("Here it comes...")
        time.sleep(1)
        await coming.delete()
        await ctx.send(f"**{random.choice(dice8)}**")
        
    except asyncio.TimeoutError:
        await message.delete()
        await ctx.send("Procces has been canceled because you didn't answer in **30** second!")

    def check10(m):
        return m.author == ctx.author and m.content == "10"

    try:
        await client.wait_for('message', check=check10, timeout=30.0)
        coming = await ctx.send("Here it comes...")
        time.sleep(1)
        await coming.delete()
        await ctx.send(f"**{random.choice(dice10)}**")
        
    except asyncio.TimeoutError:
        await message.delete()
        await ctx.send("Procces has been canceled because you didn't answer in **30** second!")

    def check12(m):
        return m.author == ctx.author and m.content == "12"

    try:
        await client.wait_for('message', check=check12, timeout=30.0)
        coming = await ctx.send("Here it comes...")
        time.sleep(1)
        await coming.delete()
        await ctx.send(f"**{random.choice(dice12)}**")
        
    except asyncio.TimeoutError:
        await message.delete()
        await ctx.send("Procces has been canceled because you didn't answer in **30** second!")

    def check20(m):
        return m.author == ctx.author and m.content == "20"

    try:
        await client.wait_for('message', check=check20, timeout=30.0)
        coming = await ctx.send("Here it comes...")
        time.sleep(1)
        await coming.delete()
        await ctx.send(f"**{random.choice(dice20)}**")
        
    except asyncio.TimeoutError:
        await message.delete()
        await ctx.send("Procces has been canceled because you didn't answer in **30** second!")

当我键入命令并选择数字 4 时，我的命令确实有效，但当我尝试另一个数字（例如 6）时，它不起作用。我究竟做错了什么？请帮忙。

那是因为它检查4首先，然后6，依此类推...即使在您发送后4，它会检查6, 8等等..当你发送时6，它会检查4首先，然后6等等..为什么你不尝试这样的事情呢：

@client.command()
async def rolldice(ctx):
    message = await ctx.send("Choose a number:\n**4**, **6**, **8**, **10**, **12**, **20** ")
    
    def check(m):
        return m.author == ctx.author

    try:
        message = await client.wait_for("message", check = check, timeout = 30.0)
        m = message.content

        if m != "4" and m != "6" and m != "8" and m != "10" and m != "12" and m != "20":
            await ctx.send("Sorry, invalid choice.")
            return
        
        coming = await ctx.send("Here it comes...")
        time.sleep(1)
        await coming.delete()
        await ctx.send(f"**{random.randint(1, int(m))}**")
    except asyncio.TimeoutError:
        await message.delete()
        await ctx.send("Procces has been canceled because you didn't respond in **30** seconds.")

Note:我建议使用await asyncio.sleep(1)代替time.sleep(1)。这样其他命令仍然有效。记得导入asyncio在这种情况下。
