Question

我创建了一个不和谐级别的机器人，但是当我使用 $rank 时，它会出错，说 get_point 未定义出租车有人帮我吗？

import discord,time,json
from discord.ext import commands
class Lvl(commands.Cog):
    def __init__(self,bot):
        self.bot = bot
    
    try:
        with open("users.json") as fp:
            users = json.load(fp)
    except Exception:
        users = {}

    def save_users():
        with open("users.json", "w+") as fp:
            json.dump(users, fp, sort_keys=True, indent=4)

    def add_points(user: discord.User, points: int):
        id = user.id
        if id not in users:
            users[id] = {}
        users[id]["points"] = users[id].get("points", 0) + points
        save_users()

    def get_points(user: discord.User):
        id = user.id
        if id in users:
            return users[id].get("points", 0)
        return 0

    @commands.Cog.listener()
    async def on_message(self , message):
        if message.author == self.bot.user:
            return
        add_points(message.author, 1)
        
    @commands.command()
    async def rank(ctx,self):
        await ctx.send(f"you have {get_points(message.author)} point")
        

    def setup(bot):
        bot.add_cog(Lvl(bot))

你的方法在一个类中，所以在定义时使用 self

    def get_points(self, user: discord.User):
    id = user.id
    if id in users:
        return users[id].get("points", 0)
    return 0

在调用 get 点时，您也需要使用 self

@commands.command()
async def rank(self, ctx):
    await ctx.send(f"you have {self.get_points(message.author)} point")

我创建了一个不和谐级别的机器人，但它收到错误说未定义
