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:

# 第五关
elif time_remain == 20 and flag:

mole.reset()
mole.setPosition(hole_pos)
pygame.time.set_timer(change_hole_event, 450)

# 关卡显示
if time_remain == 100:

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
