main.py

import sys

import pygame

from homura import Ho
from sets import Settings
import game_function as gf

def run_game():
    pygame.init()
    ai_settings = Settings()
    screen = pygame.display.set_mode((ai_settings.screen_width,ai_settings.screen_height))
    pygame.display.set_caption("Akimi Homura")
    hoho = Ho(ai_settings,screen)
    
    while True:
         gf.check_events(hoho)
         hoho.update()
         gf.update_screen(ai_settings,screen,hoho)   
run_game()

homura.py

import pygame

class Ho():
	def __init__(self,ai_settings,screen):
		self.screen = screen
		self.ai_settings = ai_settings
		
		self.image = pygame.image.load('images/Homura.bmp')
		self.rect = self.image.get_rect()
		self.screen_rect = screen.get_rect()
		
		self.rect.centery = self.screen_rect.centery
		self.rect.centerx = self.screen_rect.centerx
		
		self.centerxx = float(self.rect.centerx)
		self.centeryy = float(self.rect.centery)
		
		self.moving_right = False
		self.moving_left = False
		self.moving_up = False
		self.moving_down = False
	
	def update(self):
		if self.moving_right and self.rect.right < self.screen_rect.right:
			self.centerxx += self.ai_settings.ship_speed_factor
		if self.moving_left and self.rect.left > 0:
			self.centerxx -= self.ai_settings.ship_speed_factor
		if self.moving_up and self.rect.top > 0:
			self.centeryy -= self.ai_settings.ship_speed_factor
		if self.moving_down and self.rect.bottom < self.screen_rect.bottom:
			self.centeryy += self.ai_settings.ship_speed_factor
		
		self.rect.centerx = self.centerxx
		self.rect.centery = self.centeryy
		
	def blitme(self):
		self.screen.blit(self.image, self.rect)

sets.py

class Settings():
      def __init__(self):
          self.screen_width = 1200
          self.screen_height = 800
          self.bg_color = (147,91,165)
          self.ship_speed_factor = 1.5

运行结果如下：

import sys

import pygame

def run_game():
    pygame.init()   
    screen = pygame.display.set_mode((1200,800))
    bg_color = (147,96,165)
    pygame.display.set_caption("12-4")
    
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit()
            elif event.type == pygame.KEYDOWN:
               print(event.type)
            screen.fill(bg_color)
            pygame.display.flip()
            
run_game()
