导语

嘿！前不久刚刚给大家过一款反弹球的小游戏嘛！

不知道大家还记得不？不记得可以看下往期的内容呢，在上一期的基础上升级了这款打砖块的小游戏，界面的话也挺简单的，经典配色原汁原味哈哈哈。

大家好，我是木木子，一个上的编程下的厅堂的女码农！今天带大家编写一款经典的打砖块儿小游戏！

小科普：

打砖块最早是由雅达利公司开发的一款独立游戏，也是无数人的童年记忆。

在谷歌图片中搜索“atari breakout”（雅利达打砖块游戏），搜索结果就会变成这款游戏。把所有砖块都清除后，还能继续进入下一轮挑战。

大家也可以试试 哈哈哈~希望给大家介绍更多编程方各种知识！

​

一、准备中

1）游戏规则：

把所有砖块都清除后，还能继续进入下一轮挑战

初始化每个玩家2次机会，打完所有砖块儿即可胜利，否则失败游戏不过关！

（关卡素材、背景音乐等比较少也不展示了需要的主页源码基地见哈）

2）环境安装

本文用到的环境：python3、Pycharm、Pygame模块以及部分自带。

环境安装：pip install -i https://pypi.douban.com/simple/ +模块名

二、开始敲代码

1）配置文件

import os
 
'''游戏界面一些数值'''
SCREENWIDTH = 640
SCREENHEIGHT = 480
BRICKWIDTH = 10
BRICKHEIGHT = 10
PADDLEWIDTH = 60
PADDLEHEIGHT = 12
BALLRADIUS = 8
'''游戏素材路径'''
FONTPATH = os.path.join(os.getcwd(), 'resources/font/font.TTF')
HITSOUNDPATH = os.path.join(os.getcwd(), 'resources/audios/hit.wav')
BGMPATH = os.path.join(os.getcwd(), 'resources/audios/bgm.mp3')
LEVELROOTPATH = os.path.join(os.getcwd(), 'resources/levels')
LEVELPATHS = [os.path.join(LEVELROOTPATH, '%s.level' % str(i+1)) for i in range(len(os.listdir(LEVELROOTPATH)))]
'''一些颜色'''
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
PINK = (212, 149, 174) 
PURPLE = (168, 152, 191)
YELLOW = (245, 237, 162)
BLUE  = (51, 170, 230)
AQUA = (182, 225, 225)

2）定义一些类

import random
import pygame
 
 
'''板子'''
class Paddle(pygame.sprite.Sprite):
    def __init__(self, x, y, width, height, SCREENWIDTH, SCREENHEIGHT, **kwargs):
        pygame.sprite.Sprite.__init__(self)
        self.init_state = [x, y, width, height]
        self.rect = pygame.Rect(x, y, width, height)
        self.base_speed = 10
        self.SCREENWIDTH = SCREENWIDTH
        selIHXXQtmf.SCREENHEIGHT = SCREENHEIGHT
    '''移动板子'''
    def move(self, direction):
        if direction == 'left':
            self.rect.left = max(0, self.rect.left-self.base_speed)
        elif direction == 'right':
            self.rect.right = min(self.SCREENWIDTH, self.rect.right+self.base_speed)
        else:
            raise ValueError('Paddle.move.direction unsupport %s...' % direction)
        return True
    '''绑定到屏幕上'''
    def draw(self, screen, color):
        pygame.draw.rect(screen, color, self.rect)
        return True
    '''重置'''
    def reset(self):
        self.rect = pygame.Rect(self.init_state[0], self.init_state[1], self.init_state[2], self.init_state[3])
        return True
 
 
'''球'''
class Ball(pygame.sprite.Sprite):
    def __init__(self, x, y, radius, SCREENWIDTH, SCREENHEIGHT, **kwargs):
        pygame.sprite.Sprite.__init__(self)
        self.init_state = [x, y, radius*2, radius*2]
        self.rect = pygame.Rect(x, y, radius*2, radius*2)
        self.base_speed = [5, 5]
        self.direction = [random.choice([1, -1]), -1]
        self.radius = radius
        self.SCREENWIDTH = SCREENWIDTH
        self.SCREENHEIGHT = SCREENHEIGHT
    '''移动球'''
    def move(self):
        self.rect.left += self.direction[0] * self.base_speed[0]
        self.rect.top += self.direction[1] * self.base_speed[1]
        if self.rect.left <= 0:
            self.rect.left = 0
            self.direction[0] = -self.direction[0]
        elif self.rect.right >= self.SCREENWIDTH:
            self.rect.right = self.SCREENWIDTH
            self.direction[0] = -self.direction[0]
        if self.rect.top <= 0:
            self.rect.top = 0
            self.direction[1] = -self.direction[1]
        elif self.rect.bottom >= self.SCREENHEIGHT:
            return False
        return True
    '''改变运动速度和方向(与拍相撞时)'''
    def change(self):
        self.base_speed = [random.choice([4, 5, 6]), random.choice([4, 5, 6])]
        self.direction = [random.choice([1, -1]), -1]
        return True
    '''绑定到屏幕上'''
    def draw(self, screen, color):
        pygame.draw.circle(screen, color, (self.rect.left+self.radius, self.rect.top+self.radius), self.radius)
        return True
    '''重置'''
    def reset(self):
        self.rect = pygame.Rect(self.init_state[0], self.init_state[1], self.init_state[2], self.init_state[3])
        return True
 
 
'''砖块'''
class Brick(pygame.sprite.Sprite):
    def __init__(self, x, y, width, height, **kwargs):
        pygame.sprite.Sprite.__init__(self)
        self.init_state = [x, y, width, height]
        self.rect = pygame.Rect(x, y, width, height)
    '''绑定到屏幕上'''
    def draw(self, screen, color):
        pygame.draw.rect(screen, color, self.rect)
        return True
    '''重置'''
    def reset(self):
        self.rect = pygame.Rect(self.init_state[0], self.init_state[1], self.init_state[2], self.init_state[3])
        return True

3）定义开始、结束界面

 '''开始界面'''
    def __startInterface(self):
        clock = pygame.time.Clock()
        while True:
            for event in pygame.event.get():
                if event.type == pygame.QUIT or (event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE):
                    pygame.quit()
                    sys.exit(-1)
                if event.type == pygame.KEYDOWN and event.key == pygame.K_RETURN:
                    return
            self.screen.fill(self.cfg.AQUA)
            text1 = 'Press <Enter> to start the game'
            text2 = 'Press <Esc> to quit the game'
            text_render1 = self.font_big.render(text1, False, self.cfg.BLUE)
            text_render2 = self.font_big.render(text2, False, self.cfg.BLUE)
            self.screen.blit(text_render1, ((self.cfg.SCREENWIDTH-text_render1.get_rect().width)//2, (self.cfg.SCREENHEIGHT-text_render1.get_rect().height)//4))
            self.screen.blit(text_render2, ((self.cfg.SCREENWIDTH-text_render2.get_rect().width)//2, (self.cfg.SCREENHEIGHT-text_render2.get_rect().height)//2))
            pygame.display.flip()
            clock.tick(30)
    '''结束界面'''
    def __endInterface(self, is_win):
        if is_win:
            text1 = 'Congratulations! You win!'
        else:
            text1 = 'Game Over! You fail!'
        text2 = 'Press <R> to restart the game'
        text3 = 'Press <Esc> to quit the game.'
        clock = pygame.time.Clock()

                    return
            self.screen.fill(self.cfg.AQUA)
            text_render1 = self.font_big.render(text1, False, self.cfg.BLUE)
            text_render2 = self.font_big.render(text2, False, self.cfg.BLUE)

            pygame.display.flip()
            clock.tick(30)

4）定义游戏

class breakoutClone():
    def __init__(self, cfg, **kwargs):
        pygame.init()
        pygame.display.set_caption('Breakout clone ')

            # 将游戏精灵绑定到屏幕
            paddle.draw(self.screen, self.cfg.PURPLE)

            pygame.display.flip()
            clock.tick(30)

5）主函数与运行界面

import cfg
from modules import breakoutClone
 
'''主函数'''
def main():
    game = breakoutClone(cfg)
    game.run()
 
'''run'''
if __name__ == '__main__':
    main()
