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 = position
        self.down_len = downlen
        self.target_x = position[0]
        self.target_y = position[1] + downlen
        self.type = img_path.split('/')[-1].split('.')[0]
        self.fixed = False
        self.speed_x = 10
        self.speed_y = 10
        self.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 = True
        elif 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 = True
        elif 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 = True
        elif 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] = None
                    elif start >= 0:
                        block.target_y += GRIDSIZE
                        block.fixed = False
                        block.direction = 'down'
                        self.all_blocks[each][start + 1] = block
                    else:
                        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] = block
                start -= 1
        elif 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] = None
                elif start >= 0:
                    block = self.get_block_by_position(*[res_match[1], start])
                    block.target_y += GRIDSIZE * 3
                    block.fixed = False
                    block.direction = 'down'
                    self.all_blocks[res_match[1]][start + 3] = block
                else:
                    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] = block
                start -= 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.reward
            return self.reward
        return 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 += 1
            return self.draw_drop_animation(x, y)
        elif y < NUMGRID - 1:
            x = 0
            y += 1
            return 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 False
        return True

绘制匹配规则，绘制拼图交换效果：

        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 [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):

    '''交换拼图'''
