如何解决为什么放置文本会这样做？
我想制作简单的平台游戏。一切正常，但是当我尝试在此处输入文本时，发生了一些奇怪的事情。我真的不知道为什么会这样，因为我和以前的项目一样
这是打印屏幕：
如果你知道为什么会这样，为什么还会这样，请告诉我 这是我的代码：
from pygame import *
WIN_WIDTH = 1923
WIN_HEIGHT = 1000
disPLAY = (WIN_WIDTH,WIN_HEIGHT)
DEPTH = 32
FLAGS = 0
CAMERA_SLACK = 30
pygame.init()
green = (0,255,0)
screen = pygame.display.set_mode(disPLAY,FLAGS,DEPTH)
level = [
'PPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP','P P','P PP P','P PP P','P PP P','P PP P','P P P','P PP P P','P PP P P','P PP P P','P PPP P PP','P P LP','PSSSSSSSSSSSSSSSSSSSSsspPPSSSSSSSSSSSSSSSSSSSSSSSSsspsspPPPPPP',]
def main():
pygame.display.set_caption('BlaBlabla!')
timer = pygame.time.Clock()

bg = Surface((WIN_WIDTH,WIN_HEIGHT // 30))
bg.convert()
bg.fill(Color('#000000'))

font = pygame.font.SysFont('Consolas',22)
bg.blit(font.render(text,True,(green)),(1,1))

解决方法
您将文本 blit 到 bg 表面。然后你将该 Surface 传送到屏幕 1024 次，每个方向上每 32 个像素：
for y in range(32):
for x in range(32):
screen.blit(bg,(x * 32,y * 32))
要么使 bg 大到足以覆盖整个屏幕，然后 blit 一次：
bg = Surface(DISPLAY)
bg.convert()
bg.fill(Color('#000000'))
text = 'Score:'
font = pygame.font.SysFont('Consolas',22)
bg.blit(font.render(text,True,(green)),(100,100))
...
# in the main loop
screen.blit(bg,(0,0))
或存储文本表面并将其每帧一次 blit 到 screen 而不是 bg：
bg = Surface((WIN_WIDTH,WIN_HEIGHT // 30))
bg.convert()
bg.fill(Color('#000000'))
text = 'Score:'
font = pygame.font.SysFont('Consolas',22)
text_surf,text_rect = font.render(text,(1,1)
entities = pygame.sprite.Group()
...
# in the main loop:
screen.fill('black')
screen.blit(text_surf,100))
