PyGame os.environ SDL_VIDEO_WINDOW_POS 不起作用

问题描述

我正在尝试在 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已更新，但视觉上没有任何变化.

I'm trying to set the position of my window in PyGame, but this method doesn't work for me. It says that it's updated when I print it out, but nothing changes visually.

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()

解决方案

Pygame的早期版本(2.0.0之前)，可以通过设置SDL_VIDEO_WINDOW_POS和调用pygame.display.set_mode()(至少在某些系统中.
这已经不可能了.如果你想改变窗口的位置，你必须重新初始化 display 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.

With earlier version of Pygame (before 2.0.0), the window position could be change by setting SDL_VIDEO_WINDOW_POS and calling pygame.display.set_mode() (at least at some systems.
This is no longer possible. If you want to change the position of the window you have to reinitialize the display module pygame.display.quit() and pygame.display.init().
In any case SDL_VIDEO_WINDOW_POS needs to be set before calling pygame.display.set_mode().

小例子:

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()
