原标题：Python制作打地鼠小游戏

导语

大家好，欢迎来到 Crossin的编程教室 ！

打地鼠游戏相信大家都知道，这里就不多介绍了，反正就是不停地拿锤子打洞里钻出来的地鼠呗~

今天就给大家分享一个用python写的打地鼠小游戏。同时也祝大家在新的一年把不开心的事情统统打跑~

环境搭建

安装Python并添加到环境变量，安装 pygame 模块

pipinstall pygame

或下载离线安装：

http://www.lfd.uci.edu/~gohlke/pythonlibs/#pygame

先睹为快

获取源码后在cmd窗口运行如下命令即可：

pythonGame21.py

效果如下：

原理简介

首先，让我们确定一下游戏中有哪些元素。打地鼠打地鼠，地鼠当然得有啦，那我们就写个地鼠的游戏精灵类呗：

'''地鼠'''

classMole(pygame.sprite.Sprite):

def__init__(self, image_paths, position, **kwargs):

pygame.sprite.Sprite.__init__(self)

self.images = [pygame.transform.scale(pygame.image.load(image_paths[ 0]), ( 101, 103)),

pygame.transform.scale(pygame.image.load(image_paths[ -1]), ( 101, 103))]

self.image = self.images[ 0]

self.rect = self.image.get_rect

self.mask = pygame.mask.from_surface(self.image)

self.setPosition(position)

self.is_hammer = False

'''设置位置'''

defsetPosition(self, pos):

self.rect.left, self.rect.top = pos

'''设置被击中'''

defsetBeHammered(self):

self.is_hammer = True

'''显示在屏幕上'''

defdraw(self, screen):

ifself.is_hammer: self.image = self.images[ 1]

screen.blit(self.image, self.rect)

'''重置'''

defreset(self):

self.image = self.images[ 0]

self.is_hammer = False

地鼠有被锤子击中和未被锤子击中这两种状态，所以需要加载两张图，当地鼠被击中时从未被击中的地鼠状态图切换到被击中后的地鼠状态图(我找的图可能不太像地鼠，请各位老哥见谅)。然后我们再来定义一下锤子这个游戏精灵类，和地鼠类似，锤子也有未锤下去和已锤下去两种状态，只不过锤下去之后需要迅速恢复回未锤下去的状态。

代码实现如下：

classHammer( pygame. sprite. Sprite):

def__init__( self, image_paths, position, **kwargs):

pygame.sprite.Sprite.__init_ _( self)

self.images = [pygame.image.load(image_paths[ 0]), pygame.image.load(image_paths[ 1])]

self.image = self.images[ 0]

self.rect = self.image.get_rect

self.mask = pygame.mask.from_surface( self.images[ 1])

self.rect.left, self.rect.top = position

# 用于显示锤击时的特效

self.hammer_count = 0

self.hammer_last_time = 4

self.is_hammering = False

'''设置位置'''

defsetPosition( self, pos):

self.rect.centerx, self.rect.centery = pos

'''设置hammering'''

defsetHammering( self):

self.is_hammering = True

'''显示在屏幕上'''

defdraw( self, screen):

ifself. is_hammering:

self.image = self.images[ 1]

self.hammer_count += 1

ifself.hammer_count > self. hammer_last_time:

self.is_hammering = False

self.hammer_count = 0

else:

self.image = self.images[ 0]

screen.blit( self.image, self.rect)

OK，定义完游戏精灵之后，我们就可以开始写主程序啦。首先自然是游戏初始化：

'''游戏初始化'''

definitGame:

pygame.init

pygame.mixer.init

screen = pygame.display.set_mode(cfg.SCREENSIZE)

pygame.display.set_caption( 'Whac A Mole-微信公众号:Charles的皮卡丘')

returnscreen

然后加载必要的游戏素材和定义必要的游戏变量(我都注释的比较详细了，就不在文章里赘述一遍了，自己看注释呗~)

# 加载背景音乐和其他音效

pygame.mixer.music.load(cfg.BGM_PATH)

pygame.mixer.music.play(-1)

audios= {

'count_down': pygame.mixer.Sound(cfg.COUNT_DOWN_SOUND_PATH),

'hammering': pygame.mixer.Sound(cfg.HAMMERING_SOUND_PATH)

}

# 加载字体

font= pygame.font.Font(cfg.FONT_PATH, 40)

# 加载背景图片

bg_img= pygame.image.load(cfg.GAME_BG_IMAGEPATH)

# 开始界面

startInterface(screen,cfg.GAME_BEGIN_IMAGEPATHS)

# 地鼠改变位置的计时

hole_pos= random.choice(cfg.HOLE_POSITIONS)

change_hole_event= pygame.USEREVENT

pygame.time.set_timer(change_hole_event,800)

# 地鼠

mole= Mole(cfg.MOLE_IMAGEPATHS, hole_pos)

# 锤子

hammer= Hammer(cfg.HAMMER_IMAGEPATHS, (500, 250))

# 时钟

clock= pygame.time.Clock

# 分数

your_score= 0

接着就是游戏主循环啦：

# 游戏主循环

whileTrue:

# --游戏时间为60s

time_remain = round(( 61000- pygame.time.get_ticks) / 1000.)

# --游戏时间减少, 地鼠变位置速度变快

iftime_remain == 40:

pygame.time.set_timer(change_hole_event, 650)

eliftime_remain == 20:

pygame.time.set_timer(change_hole_event, 500)

# --倒计时音效

iftime_remain == 10:

audios[ 'count_down'].play

# --游戏结束

iftime_remain < 0: break

count_down_text = font.render( 'Time: '+str(time_remain), True, cfg.WHITE)

# --按键检测

forevent inpygame.event.get:

ifevent.type == pygame.QUIT:

pygame.quit

sys.exit

elifevent.type == pygame.MOUSEMOTION:

hammer.setPosition(pygame.mouse.get_pos)

elifevent.type == pygame.MOUSEBUTTONDOWN:

ifevent.button == 1:

hammer.setHammering

elifevent.type == change_hole_event:

hole_pos = random.choice(cfg.HOLE_POSITIONS)

mole.reset

mole.setPosition(hole_pos)

# --碰撞检测

ifhammer.is_hammering andnotmole.is_hammer:

is_hammer = pygame.sprite.collide_mask(hammer, mole)

ifis_hammer:

audios[ 'hammering'].play

mole.setBeHammered

your_score += 10

# --分数

your_score_text = font.render( 'Score: '+str(your_score), True, cfg.BROWN)

# --绑定必要的游戏元素到屏幕(注意顺序)

screen.blit(bg_img, ( 0, 0))

screen.blit(count_down_text, ( 875, 8))

screen.blit(your_score_text, ( 800, 430))

mole.draw(screen)

hammer.draw(screen)

# --更新

pygame.display.flip

clock.tick( 60)

每一部分我也都做了注释，逻辑很简单，就不多废话了。

60s后，游戏结束，我们就可以统计分数以及和历史最高分做对比了：

# 读取最佳分数(try块避免第一次游戏无.rec文件)

try:

best_score= int(open(cfg.RECORD_PATH).read)

except:

best_score= 0

# 若当前分数大于最佳分数则更新最佳分数

ifyour_score > best_score:

f= open(cfg.RECORD_PATH, 'w')

f.write(str(your_score))

f.close

为了使游戏看起来更“正式”，再随手添个开始界面和结束界面呗：

'''游戏开始界面'''

defstartInterface(screen, begin_image_paths):

begin_images = [pygame.image.load(begin_image_paths[ 0]), pygame.image.load(begin_image_paths[ 1])]

begin_image = begin_images[ 0]

whileTrue:

forevent inpygame.event.get:

ifevent.type == pygame.QUIT:

pygame.quit

sys.exit

elifevent.type == pygame.MOUSEMOTION:

mouse_pos = pygame.mouse.get_pos

ifmouse_pos[ 0] inlist(range( 419, 574)) andmouse_pos[ 1] inlist(range( 374, 416)):

begin_image = begin_images[ 1]

else:

begin_image = begin_images[ 0]

elifevent.type == pygame.MOUSEBUTTONDOWN:

ifevent.button == 1andmouse_pos[ 0] inlist(range( 419, 574)) andmouse_pos[ 1] inlist(range( 374, 416)):

returnTrue

screen.blit(begin_image, ( 0, 0))

pygame.display.update

'''结束界面'''defendInterface(screen, end_image_path, again_image_paths, score_info, font_path, font_colors, screensize):end_image = pygame.image.load(end_image_path)again_images = [pygame.image.load(again_image_paths[ 0]), pygame.image.load(again_image_paths[ 1])]again_image = again_images[ 0]font = pygame.font.Font(font_path, 50)your_score_text = font.render( 'Your Score: %s'% score_info[ 'your_score'], True, font_colors[ 0])your_score_rect = your_score_text.get_rectyour_score_rect.left, your_score_rect.top = (screensize[ 0] - your_score_rect.width) / 2, 215best_score_text = font.render( 'Best Score: %s'% score_info[ 'best_score'], True, font_colors[ 1])best_score_rect = best_score_text.get_rectbest_score_rect.left, best_score_rect.top = (screensize[ 0] - best_score_rect.width) / 2, 275whileTrue:forevent inpygame.event.get:ifevent.type == pygame.QUIT:pygame.quitsys.exitelifevent.type == pygame.MOUSEMOTION:mouse_pos = pygame.mouse.get_posifmouse_pos[ 0] inlist(range( 419, 574)) andmouse_pos[ 1] inlist(range( 374, 416)):again_image = again_images[ 1]else:again_image = again_images[ 0]elifevent.type == pygame.MOUSEBUTTONDOWN:ifevent.button == 1andmouse_pos[ 0] inlist(range( 419, 574)) andmouse_pos[ 1] inlist(range( 374, 416)):returnTruescreen.blit(end_image, ( 0, 0))screen.blit(again_image, ( 416, 370))screen.blit(your_score_text, your_score_rect)screen.blit(best_score_text, best_score_rect)pygame.display.update

大功告成~
