如何显示用户正在玩的游戏而非其自定义状态？

问题出在你只取了用户的第一个活动（after.activity），而用户手动设置的自定义"正在玩"状态会排在真正的游戏活动前面，同时自定义状态和游戏活动的类型都是ActivityType.playing，导致机器人把自定义内容当成了游戏名。

要正确识别真正的游戏，需要：

• 遍历用户的所有活动（after.activities）而非只取第一个
• 区分系统检测的游戏活动和用户自定义的playing活动：
  • 系统检测的游戏属于discord.Game类（Activity的子类）
  • 自定义的playing活动是普通Activity对象，没有官方游戏的标识（比如application_id）

修改后的代码 #

import discord
from discord.abc import GuildChannel

intents = discord.Intents.default()
intents.message_content = True
intents.presences = True
intents.members = True

client = discord.Client(intents=intents)

gameCheck = True

@client.event
async def on_ready():
  print(f'We have logged in as {client.user}')

@client.event
async def on_presence_update(before, after):
    if not gameCheck:
        return  # 检查开关状态，关闭时不执行通知
    
    # 筛选出after中所有真正的游戏活动（Game实例）
    after_games = [activity for activity in after.activities if isinstance(activity, discord.Game)]
    # 筛选出before中已有的游戏活动名称
    before_game_names = {game.name for game in before.activities if isinstance(game, discord.Game)}
    
    # 找出用户新开始玩的游戏
    new_games = [game for game in after_games if game.name not in before_game_names]
    
    for game in new_games:
        game_name = game.name
        print(f"{after.name} is now playing {game_name}")
        
        system_channel = client.guilds[0].system_channel
        if system_channel is not None:
            await system_channel.send(f"{after.name} is now playing {game_name}")

@client.event
async def on_message(message):
  global gameCheck
  if message.author == client.user:
      return

  if message.content.startswith('$toggle'):
    gameCheck = not gameCheck
    await message.channel.send(f'Game check toggled to {gameCheck}')

client.run('TOKEN')

额外优化（针对小众游戏） #

如果有些小众游戏不被识别为Game实例，可以通过检查application_id来补充判断（自定义活动没有该属性）：

after_games = [
    activity for activity in after.activities 
    if activity.type == discord.ActivityType.playing 
    and hasattr(activity, 'application_id') 
    and activity.application_id is not None
]
