我正在嘗試讓我的代碼使用 discord api 從 discord 獲取消息，并使用 pygame 將其放在黑屏上，并在中心顯示該消息。get_message() 和 main_window() 函數都單獨工作，但是當我將它與 Threading 放在一起時，get_message() 似乎不起作用。我的代碼import discordimport pygamefrom threading import Threadclient = discord.Client()new_message = "Potato"pygame.font.init()font = pygame.font.Font(None, 45)color = (255, 255, 255)txt = font.render(new_message, True, color)def main(): t1 = Thread(target=main_window()) t3 = Thread(target=get_message()) t3.start() t1.start()def main_window(): global new_message info = pygame.display.Info() screen = pygame.display.set_mode((info.current_w, info.current_h), pygame.FULLSCREEN) screen_rect = screen.get_rect() clock = pygame.time.Clock() done = False while not done: for event in pygame.event.get(): if event.type == pygame.KEYDOWN: if event.key == pygame.K_ESCAPE: done = Truescreen.fill((30, 30, 30))screen.blit(txt, txt.get_rect(center=screen_rect.center))pygame.display.flip()clock.tick(30)def get_message(): @client.event async def on_ready(): print('We have logged in as {0.user}'.format(client)) @client.event async def on_message(message): if message.author == client.user or message.author.id == MY_USER_ID: return if message.channel.id == MY_CHANNEL_ID: if message.content != " ": global new_message global txt new_message = message.content txt = font.render(new_message, True, color) client.run("MY_ACCESS_KEY")if name == 'main': pygame.init() main()我是 Python 的新手，所以如果您有任何清理或建議，我將不勝感激！謝謝！

可能是在單獨的線程中呈現文本導致了問題。根據 pygame font?render()文檔，該方法不是線程安全的。
font.render()我通過將調用和與 pygame 有關的所有內容移動到函數中來修改您的代碼main_window()。在 pygame 事件循環的每次傳遞中，它檢查全局是否new_message已更改并呈現文本（如果已更改）。
編輯：?我剛剛注意到，當您創建線程時，您指定的函數不正確。它應該是Thread(target=myFunc)（對函數的引用）而不是Thread(target=myFunc())（調用函數并傳遞結果）。
import discord
import pygame
from threading import Thread
client = discord.Client()
new_message = "Potato"
color = (255, 255, 255)
def main():
? ? t1 = Thread(target=main_window) # no parentheses on function
? ? t3 = Thread(target=get_message)
? ? t1.start()
? ? t3.start()
def main_window():
? ? pygame.init()
? ? pygame.font.init()
? ? font = pygame.font.Font(None, 45)
? ? info = pygame.display.Info()
? ? screen = pygame.display.set_mode((info.current_w, info.current_h), pygame.FULLSCREEN)
? ? screen_rect = screen.get_rect()
? ? clock = pygame.time.Clock()
? ? last_message = new_message # inital message
? ? txt = font.render(new_message, True, color) # renter initial text
? ? done = False
? ? while not done:
? ? ? ? for event in pygame.event.get():
? ? ? ? ? ? if event.type == pygame.KEYDOWN:
