python - Pygame 全屏放大

Question

我不确定这是否是 pygame 的已知问题，但它似乎在我使用全屏时放大了。我的显示器分辨率是 1920 x 1080。让我向您展示一些代码和我从中获得的输出。

import pygame, sys
from pygame.locals import *

pygame.init()
clock = pygame.time.Clock()

monitor_size = pygame.display.list_modes()[0]
print(monitor_size)
# Output: 1920x1080

FPS = 30
WINDOW_SIZE = (768, 432) # Proportional to 1920x1080, so it doesn't stretch out
SCREEN_SIZE = WINDOW_SIZE
window = pygame.display.set_mode(WINDOW_SIZE)
pygame.display.set_caption('Project')
screen = pygame.Surface(SCREEN_SIZE)

full_screen = False

def display_corners(surface):
    pygame.draw.aaline(surface, (255, 0, 0), (SCREEN_SIZE[0] - 1, 0), (SCREEN_SIZE[0] - 1, SCREEN_SIZE[1] - 1))
    pygame.draw.aaline(surface, (255, 0, 0), (0, SCREEN_SIZE[1] - 1), (SCREEN_SIZE[0] - 1, SCREEN_SIZE[1] - 1))
    pygame.draw.aaline(surface, (255, 0, 0), (0, 0), (SCREEN_SIZE[0] - 1, 0))
    pygame.draw.aaline(surface, (255, 0, 0), (0, 0), (0, SCREEN_SIZE[1] - 1))


while True:
    # Event Loop ------------------------------------------------- #
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        if event.type == KEYDOWN:
            if event.key == K_F5:
                full_screen = not full_screen
                if full_screen:
                    window_size_before = WINDOW_SIZE
                    WINDOW_SIZE = monitor_size
                    WINDOW = pygame.display.set_mode(WINDOW_SIZE, pygame.FULLSCREEN)
                
                else:
                    WINDOW_SIZE = window_size_before
                    WINDOW = pygame.display.set_mode(WINDOW_SIZE)

   
    # Rendering ------------------------------------------------- #
    screen.fill((10, 10, 10))
    display_corners(screen)
    
    if not full_screen:
        window.blit(pygame.transform.scale(screen, WINDOW_SIZE), (0,0))
    else:
        window.blit(pygame.transform.scale(screen, (WINDOW_SIZE[0], WINDOW_SIZE[1])), (0,0))
    # Update ---------------------------------------------------- #
    pygame.display.update()
    clock.tick(FPS)

所以我有一个非常基本的全屏功能。但是，当我将 monitor_size 变量设置为我的显示器大小时，我在全屏模式下看不到应该显示在屏幕两侧的红线。即使我使用的是我确切的显示器尺寸。但是经过一些反复试验，我得到了完美的显示器尺寸，它是 1600 x 900，它也使用相同的比例，所以这是有道理的。我通过使用 monitor_size = pygame.display.list_modes()[2] 得到了这个。但我不明白为什么 1920x1080(或 pygame.display.list_modes()[0])分辨率不是完美尺寸，我觉得我没有使用使用 1600 x 900 充分发挥屏幕的潜力。

您是否研究过使用从 pygame.locals 导入的 RESIZABLE 进行测试

screen = pygame.display.set_mode(WINDOW_SIZE, RESIZABLE)
