Discord Bot - Python 3 - 将用户变量传递给其他函数

Question

我正在制作一个掷骰子 Discord bot qith Python 3。骰子编号在字典中查找一个短语并输出它。我可以很好地使用六面骰子，但我希望用户能够将其改为十面骰子。

掷骰子是“！y1”，将其设置为 10 面骰子是“！y d10”。我默认将其设置为 d6，但是当我现在尝试滚动时，它给了我一个变量未定义的错误。有人可以帮我指出我所缺少的吗？

Answer 1

您有两个 if 语句都可以计算为 False，这意味着可能永远不会创建 sides 变量。

这是因为您创建的 sides 在函数之外，使其超出范围。您需要在函数内移动它或将 sides 声明为全局（不建议）。

...

#active_ybna = 6
#active_danger = 6

w=""

#Successful server connection message
@client.event
async def on_ready():
    print(f'{client.user.name} has connected to Discord!')

#Makes sure bot doesn't respond to itself
@client.event
async def on_message(message):
    sides = 6
    if message.author == client.user:
        return

    #Choose die (6 or 10)
    if message.content.startswith('!y d6'):
        sides = 6

    if message.content.startswith('!y d10'):
        sides = 10

    #Evaluate rolls
    if message.content.startswith('!y'):
        if int(message.content[2])>int(0):
            z = int(message.content[2])
            for x in range(z):   
                 y = randint(1,int(sides))
                 active_ybna = 'ybna'+ sides + '_faces()'
                 response = 'Roll ' + str(x+1) + ': ' + active_ybna(y)
                 await message.channel.send(response)
         if len(message.content)>=4:
             if int(message.content[4])>int(0):
                 z = int(message.content[4])
                 for x in range(z):
                     y=randint(1,int(sides))
                     active_danger = 'danger'+ sides + '_faces()'
                     response = 'Danger ' + str(x+1) + ': ' + active_danger(y)
                     await message.channel.send(response)

Answer 2

我认为我发布的是未声明为全局的变量。我有点简化了这一切，并把它塞进一个有多个 IF 的事件中。

还添加了一些其他代码...
