Flappy 2048的代码解析

Flappy 2048是一个结合了Flappy Bird和2048的游戏，玩家通过控制小鸟进行跳跃，将碰到的数字方块合并得到更高的分数。下面是Flappy 2048的Python源代码解析：

pygame.init()
 
SCREEN_WIDTH = 600
SCREEN_HEIGHT = 800
 
# 创建界面
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption("Flappy 2048")
background = pygame.image.load("bg.png")
 
# 加载游戏音效和字体
pygame.mixer.init()
pygame.mixer.music.load("bgm.mp3")
pygame.mixer.music.set_volume(0.4)
pygame.mixer.music.play(-1, 0.0)
jump_sound = pygame.mixer.Sound("jump.wav")
merge_sound = pygame.mixer.Sound("merge.wav")
gameover_sound = pygame.mixer.Sound("gameover.wav")
font = pygame.font.Font("font.ttf", 40)
 
# 定义小鸟类
class Bird(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.image.load("bird.png")
        self.rect = self.image.get_rect()
        self.rect.center = (SCREEN_WIDTH / 2, SCREEN_HEIGHT / 2)
        self.speed_y = 0
        self.gravity = 0.5
        self.jump_power = 10
 
    def update(self):
        # 处理重力和跳跃
        self.speed_y += self.gravity
        self.rect.centery += self.speed_y
        if self.rect.bottom >= SCREEN_HEIGHT - 50:
            self.rect.bottom = SCREEN_HEIGHT - 50
            self.speed_y = 0
        keys = pygame.key.get_pressed()
        if keys[pygame.K_SPACE]:
            self.speed_y = -self.jump_power
            jump_sound.play()
 
# 定义数字方块类
class Block(pygame.sprite.Sprite):
    def __init__(self, x, y):
        super().__init__()
        self.value = random.choice([2, 4])
        self.image = font.render(str(self.value), True, (255, 255, 255))
        self.rect = self.image.get_rect()
        self.rect.center = (x, y)
 
    def merge(self, other):
        # 合并数字方块，将value相加
        self.value += other.value
        self.image = font.render(str(self.value), True, (255, 255, 255))
        merge_sound.play()
 
# 定义游戏主循环
def main_loop():
    # 初始化游戏窗口
    all_sprites = pygame.sprite.Group()
    blocks = pygame.sprite.Group()
    bird = Bird()
    all_sprites.add(bird)
    tick_counter = 0
    block_interval = 80
    block_speed = 5
    gameover = False
    score = 0
    
    # 主循环
    while True:
        # 处理事件
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                exit()
 
        # 更新小鸟和方块
        if not gameover:
            all_sprites.update()
            tick_counter += 1
            if tick_counter >= block_interval:
                # 创建新的数字方块
                block = Block(SCREEN_WIDTH + 50, random.randint(50, SCREEN_HEIGHT - 150))
                all_sprites.add(block)
                blocks.add(block)
                tick_counter = 0
            for block in blocks:
                # 移动数字方块
                block.rect.centerx -= block_speed
                if bird.rect.colliderect(block.rect):
                    if bird.rect.centerx < block.rect.centerx:
                        # 小鸟碰到方块，游戏结束
                        gameover = True
                        gameover_sound.play()
                    else:
                        # 合并数字方块
                        nearby_blocks = pygame.sprite.spritecollide(block, blocks, False, pygame.sprite.collide_rect)
                        for nearby in nearby_blocks:
                            if nearby is not block and nearby.rect.left > block.rect.left:
                                block.merge(nearby)
                                blocks.remove(nearby)
                                all_sprites.remove(nearby)
                                score += block.value
                                break
                elif block.rect.right < 0:
                    # 数字方块离开屏幕，从列表中删除
                    blocks.remove(block)
                    all_sprites.remove(block)
 
        # 绘制背景、小鸟和方块
        screen.blit(background, (0, 0))
        all_sprites.draw(screen)
        score_text = font.render("Score: " + str(score), True, (255, 255, 255))
        screen.blit(score_text, (20, 20))
 
        # 刷新屏幕
        pygame.display.flip()
        pygame.time.Clock().tick(60)
 
if __name__ == '__main__':
    main_loop()

这个代码实现了一个基于Pygame的Flappy 2048游戏，大概的流程是这样的：

1. 加载窗口、背景、音效和字体等资源。
2. 定义小鸟、数字方块和游戏主循环等类和函数。
3. 在游戏主循环中，循环处理事件、更新小鸟和数字方块、绘制游戏画面和刷新屏幕。
4. 在更新小鸟和数字方块时处理重力和跳跃，并判断小鸟是否碰到屏幕边缘和数字方块，并合并相邻的数字方块。
5. 在绘制游戏画面时显示背景、小鸟、数字方块和得分等信息。

以上是Flappy 2048的代码解析，希望对你有所帮助！
