使用pygame制作打地鼠游戏

1、运行结果预览

开始界面

第一关

第二关

第三关

第四关

第五关

游戏结束

2、游戏功能介绍

2.1开发环境：

python版本：python3.7

2.2相关模块：

pygame模块，以及一些Python自带的模块。

2.3游戏介绍：

游戏采用120秒计时进行，

前40秒为第一关，老鼠的出现速度为很慢；

40-60秒为第二关，老鼠的出现速度为慢；

60-80秒为第三关，老鼠的出现速度为中等；

80-100秒为第四关，老鼠的出现速度为快；

100秒后为第五关，老鼠的出现速度为很快；

倒计时结束时候游戏结束，比较分数。

3、开发思路

3.1定义的py文件

3.1.1 mouse.py(主函数入口)

通过mouse.py文件进行整个打地鼠功能的链接。

3.1.2cfg.py文件(字体等基础配置)

cfg文件中定义了基础的配置，字体，颜色，大小等等

3.1.3mole.py文件(地鼠)

mole定义了地鼠，包括地鼠的图片加载，地鼠的显示，重置等

3.1.4hammer.py文件(锤子)

hammer定义了锤子，包括锤子的图片加载，锤子的显示，击中时的效果，重置等

3.1.5endinterface.py文件(结束界面)

endinterface定义了结束时候的页面，包括分数显示和最高分显示

3.1.6startinterface.py文件(开始界面)

startinterface定义了开始的页面。

3.2定义的函数

3.2.1游戏初始化

def initGame():

pygame.init()

pygame.mixer.init()

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

pygame.display.set_caption('袁鑫张晨恩的打地鼠游戏')

return screen

3.2.2游戏的主要入口

def main():

3.2.3 游戏中老鼠类

class Mole(pygame.sprite.Sprite):

3.2.4 游戏中锤子类

class Hammer(pygame.sprite.Sprite):

3.2.5 游戏中开始界面

def startInterface(screen, begin_image_paths):

3.2.6 游戏中结束界面

def endInterface(screen, end_image_path, again_image_paths, score_info, font_path, font_colors, screensize):

4、相关代码

4.1mouse.py(主函数入口)

def main():

# 初始化

screen = initGame()

4.1.1 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)

}

4.1.2加载字体

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

4.1.3 加载背景图片

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

4.1.4 开始界面

startInterface(screen, cfg.GAME_BEGIN_IMAGEPATHS)

4.1.5 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)

4.1.6 地鼠

mole = Mole(cfg.MOLE_IMAGEPATHS, hole_pos)

4.1.7 锤子

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

4.1.8 时钟

clock = pygame.time.Clock()

4.1.9 分数

your_score = 0

4.1.10 关卡

number = 1

flag = False

4.1.11 游戏主循环

while True:

# --游戏时间为120s

time_remain = round((121000 - pygame.time.get_ticks()) / 1000.)

4.1.12 游戏时间减少, 地鼠变位置速度变快

# 第一关

if time_remain == 100 and not flag:

hole_pos = random.choice(cfg.HOLE_POSITIONS)

mole.reset()

mole.setPosition(hole_pos)

pygame.time.set_timer(change_hole_event, 650)

flag = True

# 第二关

elif time_remain == 80 and not flag:

hole_pos = random.choice(cfg.HOLE_POSITIONS)

mole.reset()

mole.setPosition(hole_pos)

pygame.time.set_timer(change_hole_event, 600)

flag = True

# 第三关

elif time_remain == 60 and not flag:

hole_pos = random.choice(cfg.HOLE_POSITIONS)

mole.reset()

mole.setPosition(hole_pos)

pygame.time.set_timer(change_hole_event, 550)

flag = True

# 第四关

elif time_remain == 40 and not flag:

hole_pos = random.choice(cfg.HOLE_POSITIONS)

mole.reset()

mole.setPosition(hole_pos)

pygame.time.set_timer(change_hole_event, 500)

flag = True

# 第五关

elif time_remain == 20 and flag:

hole_pos = random.choice(cfg.HOLE_POSITIONS)

mole.reset()

mole.setPosition(hole_pos)

pygame.time.set_timer(change_hole_event, 450)

flag = False

# 关卡显示

if time_remain == 100:

number = 1

elif time_remain == 80:

number = 2

elif time_remain == 60:

number = 3

elif time_remain == 40:

number = 4

elif time_remain == 20:

number = 5

4.1.13倒计时音效

if time_remain == 10:

audios['count_down'].play()

4.1.14游戏结束

if time_remain < 0:

break

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

4.1.15按键检测

for event in pygame.event.get():

if event.type == pygame.QUIT:

pygame.quit()

sys.exit()

elif event.type == pygame.MOUSEMOTION:

hammer.setPosition(pygame.mouse.get_pos())

elif event.type == pygame.MOUSEBUTTONDOWN:

if event.button == 1:

hammer.setHammering()

elif event.type == change_hole_event:

hole_pos = random.choice(cfg.HOLE_POSITIONS)

mole.reset()

mole.setPosition(hole_pos)

4.1.16-碰撞检测

if hammer.is_hammering and not mole.is_hammer:

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

if is_hammer:

audios['hammering'].play()

mole.setBeHammered()

your_score += 10

4.1.17分数

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

your_number_text2 = font.render('第 '+str(number)+'关', True, cfg.WHITE)

4.1.18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, (800, 8))

screen.blit(your_score_text, (750, 430))

screen.blit(your_number_text2, (600, 430))

mole.draw(screen)

hammer.draw(screen)

4.1.19读取最佳分数

try:

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

except:

best_score = 0

4.1.20若当前分数大于最佳分数则更新最佳分数

if your_score > best_score:

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

f.write(str(your_score))

f.close()

4.1.21 结束界面

score_info = {'your_score': your_score, 'best_score': best_score}

is_restart = endInterface(screen, cfg.GAME_END_IMAGEPATH, cfg.GAME_AGAIN_IMAGEPATHS, score_info, cfg.FONT_PATH, [cfg.WHITE, cfg.RED], cfg.SCREENSIZE)

return is_restart
