我正在做Python速成教程中的外星人入侵项目。当我测试代码,看看飞船是否出现在屏幕上时,屏幕启动然后关闭。在
我已经查了好几个小时的代码,但没有找到原因。在
游戏:
import sys
import pygame
from settings import Settings
from ship import Ship
def run_game():
# Initialize pygame, settings, and screen object
pygame.init()
ai_settings = Settings()
screen = pygame.display.set_mode(
(ai_settings.screen_width, ai_settings.screen_height))
pygame.display.set_caption("Alien Invasion")
# Make a ship
ship = Ship(screen)
# Set background color
bg_color = (230, 230, 230)
# Start the main loop for the game
while True:
# Watch for keyboard and mouse events
for event in pygame.event.get():
if event == pygame.quit():
sys.exit()
# Redraw the screen during each pass through the loop
screen.fill(ai_settings.bg_color)
ship.blitme()
# Make most recently drawn screen visible
pygame.display.flip()
run_game()
设置:
^{pr2}$船舶:
import pygame
class Ship():
def __init__(self, screen):
self.screen = screen
# Load the ship image and get its rect.
self.image = pygame.image.load('images/ship.bmp')
self.rect = self.image.get_rect()
self.screen_rect = screen.get_rect()
# Start each new ship at the bottom center of the screen.
self.rect.centerx = self.screen_rect.centerx
self.rect.bottom = self.screen_rect.bottom
def blitme(self):
self.screen.blit(self.image, self.rect)
这就是出现的错误

没有做你期望的事情。^{} 是一个函数,它取消初始化所有pygame模块。函数返回
None
,因此条件失败。代码会在下一条试图访问pygame模块的指令时运行并崩溃。在更改为:
^{} 对象的} 的文档。在
.type
属性包含事件类型标识符。pygame.QUIT
是一个枚举数常量,用于标识退出事件。请参阅^{相关问题 更多 >
