PyGame os.environ SDL_视频窗口_位置不工作

Question

我试图在PyGame中设置窗口的位置，但这种方法对我不起作用。它说当我打印出来时它会更新，但是视觉上没有任何变化

我的代码：

    import pygame as pg
from tkinter import messagebox as mb
import time
import sys
import requests
import os

pg.init()

sc = pg.display.set_mode((1000,750))
try:
    testimg143 = open("Data\\test.txt", "r")
except:
    ud = "ginfo\\"
else:
    ud = ""
    testimg143.close()

#main game loop

gamewindowfullscreen = False

def setgamewindowcenter():
    x = 500
    y = 100
    os.environ['SDL_VIDEO_WINDOW_POS'] = "%d,%d" % (x,y)
    print(os.environ['SDL_VIDEO_WINDOW_POS'])

while True:
    for event in pg.event.get():
        if (event.type == pg.KEYUP):
            if (event.key == pg.K_F11):
                if (gamewindowfullscreen == False):
                    sc = pg.display.set_mode((0,0), pg.FULLSCREEN)
                    setgamewindowcenter()
                    gamewindowfullscreen = True
                else:
                    sc = pg.display.set_mode((1000,750))
                    setgamewindowcenter()
                    gamewindowfullscreen = False
                    
        if event.type == pg.QUIT:
                pg.quit()
                exit()

对于Pygame的早期版本（2.0.0之前），可以通过设置SDL_VIDEO_WINDOW_POS并调用^{}（至少在某些系统中是这样）来更改窗口位置。
这不再可能。如果要更改窗口的位置，必须重新初始化^{}模块pygame.display.quit()和 pygame.display.init()。
在任何情况下，都需要在调用pygame.display.set_mode()之前设置SDL_VIDEO_WINDOW_POS

最简单的例子：

import pygame as pg
import os

def setgamewindowcenter(x = 500, y = 100):
    os.environ['SDL_VIDEO_WINDOW_POS'] = "%d,%d" % (x,y)
    print(os.environ['SDL_VIDEO_WINDOW_POS'])

pg.init()
setgamewindowcenter()
sc = pg.display.set_mode((1000, 750))

gamewindowfullscreen = False
run = True
while run:
    for event in pg.event.get():
        if event.type == pg.QUIT:
            run = False

        if event.type == pg.KEYUP:
            if event.key == pg.K_F11:
                if gamewindowfullscreen == False:
                    sc = pg.display.set_mode((0,0), pg.FULLSCREEN)
                    gamewindowfullscreen = True
                else:
                    pg.display.quit()
                    setgamewindowcenter()
                    pg.display.init()
                    sc = pg.display.set_mode((1000, 750))
                    gamewindowfullscreen = False
                    
pg.quit()
exit()
