Python版《消消乐》，附源码

曾经风靡一时的消消乐，至今坐在地铁上都可以看到很多人依然在玩，想当年我也是大军中的一员，那家伙，吃饭都在玩，进入到高级的那种胜利感还是很爽的，连续消，无限消，哈哈，现在想想也是很带劲的。今天就来实现一款简易版的，后续会陆续带上高阶版的，先来尝试一把。
首先我们需要准备消消乐的素材，会放在项目的resource文件夹下面，具体我准备了7种，稍后会展示给大家看的。

开心消消乐

先初始化消消乐的游戏界面参数，就是具体显示多大，每行显示多少个方块，每个方块大小，这里我们按照这个大小来设置，数量和大小看着都还挺舒服的：


'''初始化消消乐的参数'''
WIDTH = 600
HEIGHT = 640
NUMGRID = 12
GRIDSIZE = 48
XMARGIN = (WIDTH - GRIDSIZE * NUMGRID) // 2
YMARGIN = (HEIGHT - GRIDSIZE * NUMGRID) // 2
ROOTDIR = os.getcwd()
FPS = 45

每行显示12个，每个方块48个，看看效果

接下来，我们开始实现消除的逻辑：

初始化消消乐的方格：


class elimination_block(pygame.sprite.Sprite):def __init__(self, img_path, size, position, downlen, **kwargs):pygame.sprite.Sprite.__init__(self)self.image = pygame.image.load(img_path)self.image = pygame.transform.smoothscale(self.image, size)self.rect = self.image.get_rect()self.rect.left, self.rect.top = positionself.down_len = downlenself.target_x = position[0]self.target_y = position[1] + downlenself.type = img_path.split('/')[-1].split('.')[0]self.fixed = Falseself.speed_x = 10self.speed_y = 10self.direction = 'down'

移动方块：


'''拼图块移动'''def move(self):if self.direction == 'down':self.rect.top = min(self.target_y, self.rect.top + self.speed_y)if self.target_y == self.rect.top:self.fixed = Trueelif self.direction == 'up':self.rect.top = max(self.target_y, self.rect.top - self.speed_y)if self.target_y == self.rect.top:self.fixed = Trueelif self.direction == 'left':self.rect.left = max(self.target_x, self.rect.left - self.speed_x)if self.target_x == self.rect.left:self.fixed = Trueelif self.direction == 'right':self.rect.left = min(self.target_x, self.rect.left + self.speed_x)if self.target_x == self.rect.left:self.fixed = True

获取方块的坐标：

     '''获取坐标'''def get_position(self):return self.rect.left, self.rect.top'''设置坐标'''def set_position(self, position):self.rect.left, self.rect.top = position

绘制得分，加分，还有倒计时：


'''显示剩余时间'''def show_remained_time(self):remaining_time_render = self.font.render('CountDown: %ss' % str(self.remaining_time), 1, (85, 65, 0))rect = remaining_time_render.get_rect()rect.left, rect.top = (WIDTH - 201, 6)self.screen.blit(remaining_time_render, rect)'''显示得分'''def show_score(self):score_render = self.font.render('SCORE:' + str(self.score), 1, (85, 65, 0))rect = score_render.get_rect()rect.left, rect.top = (10, 6)self.screen.blit(score_render, rect)'''显示加分'''def add_score(self, add_score):score_render = self.font.render('+' + str(add_score), 1, (255, 100, 100))rect = score_render.get_rect()rect.left, rect.top = (250, 250)self.screen.blit(score_render, rect)

生成方块：


'''生成新的拼图块'''def generate_new_blocks(self, res_match):if res_match[0] == 1:start = res_match[2]while start > -2:for each in [res_match[1], res_match[1] + 1, res_match[1] + 2]:block = self.get_block_by_position(*[each, start])if start == res_match[2]:self.blocks_group.remove(block)self.all_blocks[each][start] = Noneelif start >= 0:block.target_y += GRIDSIZEblock.fixed = Falseblock.direction = 'down'self.all_blocks[each][start + 1] = blockelse:block = elimination_block(img_path=random.choice(self.block_images), size=(GRIDSIZE, GRIDSIZE),position=[XMARGIN + each * GRIDSIZE, YMARGIN - GRIDSIZE],downlen=GRIDSIZE)self.blocks_group.add(block)self.all_blocks[each][start + 1] = blockstart -= 1elif res_match[0] == 2:start = res_match[2]while start > -4:if start == res_match[2]:for each in range(0, 3):block = self.get_block_by_position(*[res_match[1], start + each])self.blocks_group.remove(block)self.all_blocks[res_match[1]][start + each] = Noneelif start >= 0:block = self.get_block_by_position(*[res_match[1], start])block.target_y += GRIDSIZE * 3block.fixed = Falseblock.direction = 'down'self.all_blocks[res_match[1]][start + 3] = blockelse:block = elimination_block(img_path=random.choice(self.block_images), size=(GRIDSIZE, GRIDSIZE),position=[XMARGIN + res_match[1] * GRIDSIZE, YMARGIN + start * GRIDSIZE],downlen=GRIDSIZE * 3)self.blocks_group.add(block)self.all_blocks[res_match[1]][start + 3] = blockstart -= 1

绘制拼图，移除，匹配，下滑的效果等：


'''移除匹配的block'''def clear_matched_block(self, res_match):if res_match[0] > 0:self.generate_new_blocks(res_match)self.score += self.rewardreturn self.rewardreturn 0'''游戏界面的网格绘制'''def draw_grids(self):for x in range(NUMGRID):for y in range(NUMGRID):rect = pygame.Rect((XMARGIN + x * GRIDSIZE, YMARGIN + y * GRIDSIZE, GRIDSIZE, GRIDSIZE))self.draw_block(rect, color=(0, 0, 255), size=1)'''画矩形block框'''def draw_block(self, block, color=(255, 0, 255), size=4):pygame.draw.rect(self.screen, color, block, size)'''下落特效'''def draw_drop_animation(self, x, y):if not self.get_block_by_position(x, y).fixed:self.get_block_by_position(x, y).move()if x < NUMGRID - 1:x += 1return self.draw_drop_animation(x, y)elif y < NUMGRID - 1:x = 0y += 1return self.draw_drop_animation(x, y)else:return self.is_all_full()'''是否每个位置都有拼图块了'''def is_all_full(self):for x in range(NUMGRID):for y in range(NUMGRID):if not self.get_block_by_position(x, y).fixed:return Falsereturn True

绘制匹配规则，绘制拼图交换效果：


'''检查有无拼图块被选中'''def check_block_selected(self, position):for x in range(NUMGRID):for y in range(NUMGRID):if self.get_block_by_position(x, y).rect.collidepoint(*position):return [x, y]return None'''是否有连续一样的三个块(无--返回0/水平--返回1/竖直--返回2)'''def is_block_matched(self):for x in range(NUMGRID):for y in range(NUMGRID):if x + 2 < NUMGRID:if self.get_block_by_position(x, y).type == self.get_block_by_position(x + 1, y).type == self.get_block_by_position(x + 2,y).type:return [1, x, y]if y + 2 < NUMGRID:if self.get_block_by_position(x, y).type == self.get_block_by_position(x, y + 1).type == self.get_block_by_position(x,y + 2).type:return [2, x, y]return [0, x, y]'''根据坐标获取对应位置的拼图对象'''def get_block_by_position(self, x, y):return self.all_blocks[x][y]'''交换拼图'''def swap_block(self, block1_pos, block2_pos):margin = block1_pos[0] - block2_pos[0] + block1_pos[1] - block2_pos[1]if abs(margin) != 1:return Falseblock1 = self.get_block_by_position(*block1_pos)block2 = self.get_block_by_position(*block2_pos)if block1_pos[0] - block2_pos[0] == 1:block1.direction = 'left'block2.direction = 'right'elif block1_pos[0] - block2_pos[0] == -1:block2.direction = 'left'block1.direction = 'right'elif block1_pos[1] - block2_pos[1] == 1:block1.direction = 'up'block2.direction = 'down'elif block1_pos[1] - block2_pos[1] == -1:block2.direction = 'up'block1.direction = 'down'block1.target_x = block2.rect.leftblock1.target_y = block2.rect.topblock1.fixed = Falseblock2.target_x = block1.rect.leftblock2.target_y = block1.rect.topblock2.fixed = Falseself.all_blocks[block2_pos[0]][block2_pos[1]] = block1self.all_blocks[block1_pos[0]][block1_pos[1]] = block2return True

准备工作差不多了，开始主程序吧：

def main():pygame.init()screen = pygame.display.set_mode((WIDTH, HEIGHT))pygame.display.set_caption('开心消消乐')# 加载背景音乐pygame.mixer.init()pygame.mixer.music.load(os.path.join(ROOTDIR, "resources/audios/bg.mp3"))pygame.mixer.music.set_volume(0.6)pygame.mixer.music.play(-1)# 加载音效sounds = {}sounds['mismatch'] = pygame.mixer.Sound(os.path.join(ROOTDIR, 'resources/audios/badswap.wav'))sounds['match'] = []for i in range(6):sounds['match'].append(pygame.mixer.Sound(os.path.join(ROOTDIR, 'resources/audios/match%s.wav' % i)))# 加载字体font = pygame.font.Font(os.path.join(ROOTDIR, 'resources/font.TTF'), 25)# 图片加载block_images = []for i in range(1, 8):block_images.append(os.path.join(ROOTDIR, 'resources/images/gem%s.png' % i))# 主循环game = InitGame(screen, sounds, font, block_images)while True:score = game.start()flag = False# 一轮游戏结束后玩家选择重玩或者退出while True:for event in pygame.event.get():if event.type == pygame.QUIT or (event.type == pygame.KEYUP and event.key == pygame.K_ESCAPE):pygame.quit()sys.exit()elif event.type == pygame.KEYUP and event.key == pygame.K_r:flag = Trueif flag:breakscreen.fill((135, 206, 235))text0 = 'Final score: %s' % scoretext1 = 'Press <R> to restart the game.'text2 = 'Press <Esc> to quit the game.'y = 150for idx, text in enumerate([text0, text1, text2]):text_render = font.render(text, 1, (85, 65, 0))rect = text_render.get_rect()if idx == 0:rect.left, rect.top = (212, y)elif idx == 1:rect.left, rect.top = (122.5, y)else:rect.left, rect.top = (126.5, y)y += 100screen.blit(text_render, rect)pygame.display.update()game.reset()'''test'''
if __name__ == '__main__':main()

运行main.py就可以开始游戏了，看看效果吧！
