Python Pygame實戰之打磚塊小遊戲
導語
嘿!前不久剛剛給大傢過一款反彈球的小遊戲嘛!
不知道大傢還記得不?不記得可以看下往期的內容呢,在上一期的基礎上升級瞭這款打磚塊的小遊戲,界面的話也挺簡單的,經典配色原汁原味哈哈哈。
大傢好,我是木木子,一個上的編程下的廳堂的女碼農!今天帶大傢編寫一款經典的打磚塊兒小遊戲!
小科普:
打磚塊最早是由雅達利公司開發的一款獨立遊戲,也是無數人的童年記憶。
在谷歌圖片中搜索“atari breakout”(雅利達打磚塊遊戲),搜索結果就會變成這款遊戲。把所有磚塊都清除後,還能繼續進入下一輪挑戰。
大傢也可以試試 哈哈哈~希望給大傢介紹更多編程方各種知識!
一、準備中
1)遊戲規則:
把所有磚塊都清除後,還能繼續進入下一輪挑戰
初始化每個玩傢2次機會,打完所有磚塊兒即可勝利,否則失敗遊戲不過關!
(關卡素材、背景音樂等比較少也不展示瞭需要的主頁源碼基地見哈)
2)環境安裝
本文用到的環境:Python3、Pycharm、Pygame模塊以及部分自帶。
環境安裝:pip install -i https://pypi.douban.com/simple/ +模塊名
二、開始敲代碼
1)配置文件
import os '''遊戲界面一些數值''' SCREENWIDTH = 640 SCREENHEIGHT = 480 BRICKWIDTH = 10 BRICKHEIGHT = 10 PADDLEWIDTH = 60 PADDLEHEIGHT = 12 BALLRADIUS = 8 '''遊戲素材路徑''' 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)))] '''一些顏色''' 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)定義一些類
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 self.SCREENHEIGHT = SCREENHEIGHT '''移動板子''' 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 '''綁定到屏幕上''' 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 '''移動球''' 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 '''改變運動速度和方向(與拍相撞時)''' 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 '''綁定到屏幕上''' 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 '''磚塊''' 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) '''綁定到屏幕上''' 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)定義開始、結束界面
'''開始界面''' 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) '''結束界面''' 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() 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_r: 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) text_render3 = self.font_big.render(text3, 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)) self.screen.blit(text_render3, ((self.cfg.SCREENWIDTH-text_render3.get_rect().width)//2, (self.cfg.SCREENHEIGHT-text_render2.get_rect().height)//1.5)) pygame.display.flip() clock.tick(30)
4)定義遊戲
