在 python 中编写一个不和谐的机器人

Question

我有一个有效的货币系统，但我们想要赚钱的方法。所以我想做迷你游戏，所以我做了一个掷硬币的游戏，但我不能让它工作，它告诉我当我尝试它时找不到命令。我也想做它所以游戏成本>货币所以你可以赢一点，所以基本上投注

from discord.ext import commands
import discord
import json
import random
from discord.ext.commands import Bot

import time
import asyncio
bot = commands.Bot('$')

amounts = {}

@bot.event
async def on_ready():
    global amounts
    try:
        with open('amounts.json') as f:
            amounts = json.load(f)
    except FileNotFoundError:
        print("Could not load amounts.json")
        amounts = {}

@bot.command(pass_context=True)
async def balance(ctx):
    id = str(ctx.message.author.id)
    if id in amounts:
        await ctx.send("You have {} :Ereb: in the bank".format(amounts[id]))
    else:

bot.run("token")

    ```

您需要使用bot.event 而不是bot.command 来装饰您的on_message 回调。您还需要添加bot.process_commands 行，以便正常调用其他命令。

@bot.event
async def on_message(message):
    if message.content.startswith('$coinflip'):
        randomlist = ["heads","tails",]
        await client.send_message(message.channel,(random.choice(randomlist)))
    else:
        await bot.process_commands(message)
