Discord Python Bot：升级系统

Question

所以我在谷歌上搜索了几个不同的搜索，并观看了这个视频https://www.youtube.com/watch?v=pKkrCHnun0M，关于为我的机器人制作关卡系统。基本上，机器人（IN PYTHON）就像一个冒险坦克游戏；游戏给你一个坦克开始，允许你选择一张地图，移动到地图的不同区域，并会使用 rng 来判断是否有敌方坦克。每个被摧毁的敌方坦克会给你 10 点经验值。现在，在前面提到的视频中，为了添加 xp，他使用了消息，并且还在玩家进入服务器时开始了他们的统计资料。

现在，我希望我的用户在输入命令“&stats”后开始他的个人资料。在视频中，他使用了 json。之前没用过json，自然是一头雾水，不过我还是按照视频的指导去做的。

我收到此错误：

Ignoring exception in on_message
Traceback (most recent call last):  File "/home/runner/.local/share/virtualenvs/python3/lib/python3.
7/site-packages/discord/client.py", line 270, in _run_event
    await coro(*args, **kwargs)
  File "main.py", line 72, in on_message
    await level_up(users, author, message.channel)  File "main.py", line 435, in level_up
    lvl_end = float('experience ** 1/2')
ValueError: could not convert string to float: 'experience ** 1/2'

在我的测试服务器上输入任何消息时。但是，唉，我担心这并不重要。 我正在 repl.it 中构建这个机器人，我应该在这一点上提到， 因此，我想弄清楚如何根据命令启动 json 文件，并且我还想通过消灭敌人将 xp 添加到玩家的个人资料中（以及杀死数量，但这并不重要）。我也需要关卡。目前我所有这些东西的代码是

@client.event
async def on_message(message):
  with open('users.json', 'r') as f:
    users = json.load(f)

    await update_data(users, member)



  with open("users.json", 'w') as f:
    json.dump(users, f)
@client.event
async def on_message(message):
  author = message.author

  with open('users.json', 'r') as f:
    users = json.load(f)

    await update_data(users, author)
    await add_experience(users, author, 5)
    await level_up(users, author, message.channel)
  with open("users.json", 'w') as f:
    json.dump(users, f)


  if message.content.startswith("&stats"):
    global Pxp
    global KA
    Pxp = 0
    KA = 0
    await message.channel.send("XP: " + str(Pxp) + ". Enemy Tanks Killed: " + str(KA) + ".")
  if message.content.startswith('&start'):
    await message.channel.send('Choose vehicle: VT-4, M1 Abrams, T-18 Armata. 1, 2, 3.')

在底部，

async def update_data(users, user):
  if not user.id in users:
    users[user.id] = {}
    users[user.id]['experience'] = 0
    users[user.id]['level'] = 1
async def add_experience(users, user, exp):
  users[user.id]['experience'] += exp

async def level_up(users, user, channel):
  experience = users[user.id]['experience']
  lvl_start = users[user.id]['level']
  lvl_end = float('experience ** 1/2')

  if level_start < lvl_end:
    await message.channel.send('{} leveled up to level {}'.format(user.mention, lvl_end))
    users[user.id]['level'] = lvl_end

请注意，最后一个 sn-p 会生成之前发布的错误。

这也是我的第一篇文章，我不知道我应该说得有多具体，请多多关照 :^) 很抱歉这么长，如果都错了，请告诉我。

感谢任何帮助。如果您想查看更多代码，请询问。

我已经尽力了，我已经做了一个关卡系统！它是特定于服务器的，并显示了您需要获得的经验值才能达到下一个级别。

@client.event
async def on_message(message):
    if not message.author.bot:
        print('function load')
        with open('level.json','r') as f:
            users = json.load(f)
            print('file load')
        await update_data(users, message.author,message.guild)
        await add_experience(users, message.author, 4, message.guild)
        await level_up(users, message.author,message.channel, message.guild)

        with open('level.json','w') as f:
            json.dump(users, f)
    await client.process_commands(message)




async def update_data(users, user,server):
    if not str(server.id) in users:
        users[str(server.id)] = {}
        if not str(user.id) in users[str(server.id)]:
            users[str(server.id)][str(user.id)] = {}
            users[str(server.id)][str(user.id)]['experience'] = 0
            users[str(server.id)][str(user.id)]['level'] = 1
    elif not str(user.id) in users[str(server.id)]:
            users[str(server.id)][str(user.id)] = {}
            users[str(server.id)][str(user.id)]['experience'] = 0
            users[str(server.id)][str(user.id)]['level'] = 1

async def add_experience(users, user, exp, server):
  users[str(user.guild.id)][str(user.id)]['experience'] += exp

async def level_up(users, user, channel, server):
  experience = users[str(user.guild.id)][str(user.id)]['experience']
  lvl_start = users[str(user.guild.id)][str(user.id)]['level']
  lvl_end = int(experience ** (1/4))
  
  if lvl_start < lvl_end:
      await channel.send('{} has leveled up to Level {}'.format(user.mention, lvl_end))
      users[str(user.guild.id)][str(user.id)]['level'] = lvl_end


@client.command(aliases = ['rank','lvl'])
async def level(ctx,member: discord.Member = None):

    if not member:
        user = ctx.message.author
        with open('level.json','r') as f:
        users = json.load(f)
        lvl = users[str(ctx.guild.id)][str(user.id)]['level']
        exp = users[str(ctx.guild.id)][str(user.id)]['experience']

        embed = discord.Embed(title = 'Level {}'.format(lvl), description = f"{exp} XP " ,color = discord.Color.green())
        embed.set_author(name = ctx.author, icon_url = ctx.author.avatar_url)
        await ctx.send(embed = embed)
    else:
      with open('level.json','r') as f:
          users = json.load(f)
      lvl = users[str(ctx.guild.id)][str(member.id)]['level']
      exp = users[str(ctx.guild.id)][str(member.id)]['experience']
      embed = discord.Embed(title = 'Level {}'.format(lvl), description = f"{exp} XP" ,color = discord.Color.green())
      embed.set_author(name = member, icon_url = member.avatar_url)

      await ctx.send(embed = embed)
