中秋将至利用python画一些月饼从天而降不用买了

导语

好消息！下一个假期已经在路上了，正在向我们招手呢！

大家只要再坚持5天

就能迎来中秋小长假啦~

“海上生明月，天涯共此时”

又是一年中秋至！快跟着小编来看看怎么寓教于乐吧～～

今天带大家编写一款应时应景的中秋小游戏！

天上掉月饼啦~天上掉月饼啦~天上掉月饼啦~

准备好相应的素材如下：

环境安装：

Python3.6、pycharm2021、游戏模块Pygame。

安装：pip install  pygame

初始化游戏加载素材：

def initGame():

pygame.init()
   screen = pygame.display.set_mode(cfg.SCREENSIZE)
   pygame.display.set_caption('中秋月饼小游戏')

game_images = {}
   for key, value in cfg.IMAGE_PATHS.items():
       if isinstance(value, list):
           images = []
           for item in value: images.append(pygame.image.load(item))
           game_images[key] = images
       else:
           game_images[key] = pygame.image.load(value)
   game_sounds = {}
   for key, value in cfg.AUDIO_PATHS.items():
       if key == 'bgm': continue
       game_sounds[key] = pygame.mixer.Sound(value)

return screen, game_images, game_sounds

主函数定义：

def main():
   # 初始化
   screen, game_images, game_sounds = initGame()
   # 播放背景音乐
   pygame.mixer.music.load(cfg.AUDIO_PATHS['bgm'])
   pygame.mixer.music.play(-1, 0.0)
   # 字体加载
   font = pygame.font.Font(cfg.FONT_PATH, 40)
   # 定义hero
   hero = Hero(game_images['hero'], position=(375, 520))
   # 定义掉落组
   food_sprites_group = pygame.sprite.Group()
   generate_food_freq = random.randint(10, 20)
   generate_food_count = 0
   # 当前分数/历史最高分
   score = 0
   highest_score = 0 if not os.path.exists(cfg.HIGHEST_SCORE_RECORD_FILEPATH) else int(open(cfg.HIGHEST_SCORE_RECORD_FILEPATH).read())
   # 游戏主循环
   clock = pygame.time.Clock()
   while True:
       # --填充背景
       screen.fill(0)
       screen.blit(game_images['background'], (0, 0))
       # --倒计时信息
       countdown_text = 'Count down: ' + str((90000 - pygame.time.get_ticks()) // 60000) + ":" + str((90000 - pygame.time.get_ticks()) // 1000 ％ 60).zfill(2)
       countdown_text = font.render(countdown_text, True, (0, 0, 0))
       countdown_rect = countdown_text.get_rect()
       countdown_rect.topright = [cfg.SCREENSIZE[0]-30, 5]
       screen.blit(countdown_text, countdown_rect)
       # --按键检测
       for event in pygame.event.get():
           if event.type == pygame.QUIT:
               pygame.quit()
               sys.exit()
       key_pressed = pygame.key.get_pressed()
       if key_pressed[pygame.K_a] or key_pressed[pygame.K_LEFT]:
           hero.move(cfg.SCREENSIZE, 'left')
       if key_pressed[pygame.K_d] or key_pressed[pygame.K_RIGHT]:
           hero.move(cfg.SCREENSIZE, 'right')
       # --随机生成
       generate_food_count += 1
       if generate_food_count > generate_food_freq:
           generate_food_freq = random.randint(10, 20)
           generate_food_count = 0
           food = Food(game_images, random.choice(['gold',] * 10 + ['apple']), cfg.SCREENSIZE)
           food_sprites_group.add(food)
       # --更新掉落
       for food in food_sprites_group:
           if food.update(): food_sprites_group.remove(food)
       # --碰撞检测
       for food in food_sprites_group:
           if pygame.sprite.collide_mask(food, hero):
               game_sounds['get'].play()
               food_sprites_group.remove(food)
               score += food.score
               if score > highest_score: highest_score = score
       # --画hero
       hero.draw(screen)
       # --画
       food_sprites_group.draw(screen)
       # --显示得分
       score_text = f'Score: {score}, Highest: {highest_score}'
       score_text = font.render(score_text, True, (0, 0, 0))
       score_rect = score_text.get_rect()
       score_rect.topleft = [5, 5]
       screen.blit(score_text, score_rect)
       # --判断游戏是否结束
       if pygame.time.get_ticks() >= 90000:
           break
       # --更新屏幕
       pygame.display.flip()
       clock.tick(cfg.FPS)
   # 游戏结束, 记录最高分并显示游戏结束画面
   fp = open(cfg.HIGHEST_SCORE_RECORD_FILEPATH, 'w')
   fp.write(str(highest_score))
   fp.close()
   return showEndGameInterface(screen, cfg, score, highest_score)

定义月饼、灯笼等掉落：

import pygame
import random

class Food(pygame.sprite.Sprite):
   def __init__(self, images_dict, selected_key, screensize, **kwargs):
       pygame.sprite.Sprite.__init__(self)
       self.screensize = screensize
       self.image = images_dict[selected_key]
       self.mask = pygame.mask.from_surface(self.image)
       self.rect = self.image.get_rect()
       self.rect.left, self.rect.bottom = random.randint(20, screensize[0]-20), -10
       self.speed = random.randrange(5, 10)
       self.score = 1 if selected_key == 'gold' else 5
   '''更新食物位置'''
   def update(self):
       self.rect.bottom += self.speed
       if self.rect.top > self.screensize[1]:
           return True
       return False

定义接月饼的人物：

import pygame

class Hero(pygame.sprite.Sprite):
   def __init__(self, images, position=(375, 520), **kwargs):
       pygame.sprite.Sprite.__init__(self)
       self.images_right = images[:5]
       self.images_left = images[5:]
       self.images = self.images_right.copy()
       self.image = self.images[0]
       self.mask = pygame.mask.from_surface(self.image)
       self.rect = self.image.get_rect()
       self.rect.left, self.rect.top = position
       self.diretion = 'right'
       self.speed = 8
       self.switch_frame_count = 0
       self.switch_frame_freq = 1
       self.frame_index = 0
   '''左右移动hero'''
   def move(self, screensize, direction):
       assert direction in ['left', 'right']
       if direction != self.diretion:
           self.images = self.images_left.copy() if direction == 'left' else self.images_right.copy()
           self.image = self.images[0]
           self.diretion = direction
           self.switch_frame_count = 0
       self.switch_frame_count += 1
       if self.switch_frame_count ％ self.switch_frame_freq == 0:
           self.switch_frame_count = 0
           self.frame_index = (self.frame_index + 1) ％ len(self.images)
           self.image = self.images[self.frame_index]
       if direction == 'left':
           self.rect.left = max(self.rect.left-self.speed, 0)
       else:
           self.rect.left = min(self.rect.left+self.speed, screensize[0])
   '''画到屏幕上'''
   def draw(self, screen):
       screen.blit(self.image, self.rect)

游戏结束界面：设置的一分30秒结束接到多少就是多少分数。

import sys
import pygame

'''游戏结束画面'''
def showEndGameInterface(screen, cfg, score, highest_score):
   # 显示的文本信息设置
   font_big = pygame.font.Font(cfg.FONT_PATH, 60)
   font_small = pygame.font.Font(cfg.FONT_PATH, 40)
   text_title = font_big.render(f"Time is up!", True, (255, 0, 0))
   text_title_rect = text_title.get_rect()
   text_title_rect.centerx = screen.get_rect().centerx
   text_title_rect.centery = screen.get_rect().centery - 100
   text_score = font_small.render(f"Score: {score}, Highest Score: {highest_score}", True, (255, 0, 0))
   text_score_rect = text_score.get_rect()
   text_score_rect.centerx = screen.get_rect().centerx
   text_score_rect.centery = screen.get_rect().centery - 10
   text_tip = font_small.render(f"Enter Q to quit game or Enter R to restart game", True, (255, 0, 0))
   text_tip_rect = text_tip.get_rect()
   text_tip_rect.centerx = screen.get_rect().centerx
   text_tip_rect.centery = screen.get_rect().centery + 60
   text_tip_count = 0
   text_tip_freq = 10
   text_tip_show_flag = True
   # 界面主循环
   clock = pygame.time.Clock()
   while True:
       screen.fill(0)
       for event in pygame.event.get():
           if event.type == pygame.QUIT:
               pygame.quit()
               sys.exit()
           elif event.type == pygame.KEYDOWN:
               if event.key == pygame.K_q:
                   return False
               elif event.key == pygame.K_r:
                   return True
       screen.blit(text_title, text_title_rect)
       screen.blit(text_score, text_score_rect)
       if text_tip_show_flag:
           screen.blit(text_tip, text_tip_rect)
       text_tip_count += 1
       if text_tip_count ％ text_tip_freq == 0:
           text_tip_count = 0
           text_tip_show_flag = not text_tip_show_flag
       pygame.display.flip()
       clock.tick(cfg.FPS)
