我正在瀏覽 pygame 1.9.6 的文檔，已經讀到了第 29 頁，老實說，我只是無法理解為什么我不能讓它按照它所說的去做（用紅色制作一個綠色矩形）點和黑色文本定義 4 個角、4 個中點和中心點。文檔代碼可在第 29 頁查看： https://buildmedia.readthedocs.org/media/pdf/pygame/latest/pygame.pdf我覺得他們提供的示例遺漏了很多東西，所以我稍微嘗試了一下，但已經達到了我只想看看如何讓它按照它所說的去做的地步。我的變化：import pygamefrom pygame.locals import *from pygame.rect import *from pygame.font import *def draw_point(text, pos): img = font.render(text, True, Black) pygame.draw.circle(screen, RED, pos, 3) screen.blit(img, pos)SIZE = 500, 200RED = (255, 0, 0)GRAY = (150, 150, 150)GREEN = (255, 0, 0)BLACK = (255, 255, 255)pygame.init()screen = pygame.display.set_mode(SIZE)rect = Rect(50, 40, 250, 80)##print(f'x={rect.x}, y={rect.y}, w={rect.w}, h={rect.h}')##print(f'left={rect.left}, top={rect.top}, right={rect.right}, bottom={rect.bottom}')##print(f'center={rect.center}')running = Truewhile running: for event in pygame.event.get(): if event.type == QUIT: running = False screen.fill(GRAY) pygame.draw.rect(screen, GREEN, rect, 4) for pt in pts: draw_point(pt, eval('rect.'+pt)) pygame.display.flip()pygame.quit()任何幫助表示贊賞！

該變量pts位于第 25 頁
pts = ('topleft', 'topright', 'bottomleft', 'bottomright',
'midtop', 'midright', 'midbottom', 'midleft', 'center')
該變量font位于第 36 頁：
font = pygame.font.Font(None, 24)
完整示例：
import pygame
from pygame.locals import *
from pygame.rect import *
from pygame.font import *
def draw_point(text, pos):
img = font.render(text, True, BLACK)
pygame.draw.circle(screen, RED, pos, 3)
screen.blit(img, pos)
SIZE = 500, 200
RED = (255, 0, 0)
GRAY = (150, 150, 150)
GREEN = (0, 255, 0)
BLACK = (0, 0, 0)
pygame.init()
screen = pygame.display.set_mode(SIZE)
font = pygame.font.Font(None, 24)
rect = Rect(50, 40, 250, 80)
pts = ('topleft', 'topright', 'bottomleft', 'bottomright',
'midtop', 'midright', 'midbottom', 'midleft', 'center')
running = True
while running:
for event in pygame.event.get():
if event.type == QUIT:
running = False
screen.fill(GRAY)
pygame.draw.rect(screen, GREEN, rect, 4)
for pt in pts:
draw_point(pt, eval('rect.'+pt))
pygame.display.flip()
pygame.quit()
