好消息！下一個假期已經(jīng)在路上了，正在向我們招手呢！
大家只要再堅持5天
就能迎來中秋小長假啦~
“海上生明月，天涯共此時”
又是一年中秋至！快跟著小編來看看怎么寓教于樂吧～～
今天帶大家編寫一款應時應景的中秋小游戲！
天上掉月餅啦~天上掉月餅啦~天上掉月餅啦~
正文
準備好相應的素材如下：
環(huán)境安裝：
Python3.6、pycharm2021、游戲模塊Pygame。
安裝：pip install pygame
初始化游戲加載素材：
def initGame():
pygame.init()
screen = pygame.display.set_mode(cfg.SCREENSIZE)
pygame.display.set_caption('中秋月餅小游戲')
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
主函數(shù)定義：
def main():
# 初始化
screen, game_images, game_sounds = initGame()
# 播放背景音樂
pygame.mixer.music.load(cfg.AUDIO_PATHS['bgm'])
pygame.mixer.music.play(-1, 0.0)
# 字體加載
font = pygame.font.Font(cfg.FONT_PATH, 40)
# 定義hero
hero = Hero(game_images['hero'], position=(375, 520))
# 定義掉落組
food_sprites_group = pygame.sprite.Group()
generate_food_freq = random.randint(10, 20)
generate_food_count = 0
# 當前分數(shù)/歷史最高分
score = 0
highest_score = 0 if not os.path.exists(cfg.HIGHEST_SCORE_RECORD_FILEPATH) else int(open(cfg.HIGHEST_SCORE_RECORD_FILEPATH).read())
# 游戲主循環(huán)
clock = pygame.time.Clock()
while True:
# --填充背景
screen.fill(0)
screen.blit(game_images['background'], (0, 0))
# --倒計時信息
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)
# --按鍵檢測
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')
# --隨機生成
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)
# --碰撞檢測
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
# --畫hero
hero.draw(screen)
# --畫
food_sprites_group.draw(screen)
# --顯示得分
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)
# --判斷游戲是否結(jié)束
if pygame.time.get_ticks() >= 90000:
break
# --更新屏幕
pygame.display.flip()
clock.tick(cfg.FPS)
# 游戲結(jié)束, 記錄最高分并顯示游戲結(jié)束畫面
fp = open(cfg.HIGHEST_SCORE_RECORD_FILEPATH, 'w')
fp.write(str(highest_score))
fp.close()
return showEndGameInterface(screen, cfg, score, highest_score)
定義月餅、燈籠等掉落：
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
定義接月餅的人物：
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 '''左右移動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]) '''畫到屏幕上''' def draw(self, screen): screen.blit(self.image, self.rect)
游戲結(jié)束界面：設置的一分30秒結(jié)束接到多少就是多少分數(shù)。
import sys
import pygame
'''游戲結(jié)束畫面'''
def showEndGameInterface(screen, cfg, score, highest_score):
# 顯示的文本信息設置
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.centery = screen.get_rect().centery + 60
text_tip_count = 0
text_tip_freq = 10
text_tip_show_flag = True
# 界面主循環(huán)
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:

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)
