自制打地鼠游戏,自制打地鼠游戏玩法与规则
本文主要介绍如何用Python实现打地鼠这个小游戏。本文中的示例代码非常详细,具有一定的参考价值。感兴趣的朋友可以参考一下。

简介
相信大家都知道打gopher的游戏规则,这里就不介绍了。反正我就是不停的用锤子砸从洞里钻出来的gopher
首先,我们来确定游戏中有哪些元素。Gopher,Gopher,当然要有Gopher,所以我们写一个Gopher的游戏精灵类:
地鼠
鼹鼠类(pygame.sprite.Sprite):
def __init__(self,image_paths,position,**kwargs):
py game . sprite . sprite . _ _ init _ _(self)
self . images=[py game . transform . scale(py game . image . load(image _ paths[0]),(101,103)),
py game . transform . scale(py game . image . load(image _ paths[-1]),(101,103))]
self.image=self.images[0]
self.rect=self.image.get_rect()
self . mask=py game . mask . from _ surface(self . image)
自我设定位置(位置)
self.is_hammer=False
设置位置
定义设定位置(自身,位置):
self.rect.left,self.rect.top=pos
设置被点击
def setBeHammered(self):
self.is_hammer=True
显示在屏幕上
def draw(自身,屏幕):
if self . is _ hammer : self . image=self . images[1]
screen.blit(self.image,self.rect)
重置
定义重置(自我):
self.image=self.images[0]
self.is_hammer=False
很明显,地鼠有两种状态,被锤子砸到和没被锤子砸到,所以需要加载两个图。一只地鼠被击中时从未被击中的地鼠的图形切换到被击中后的地鼠的图形(我要找的图形可能看起来不像地鼠,请见谅兄弟)。那我们来定义一下锤子,一个游戏精灵类。与地鼠类似,锤子有两种状态,即未锤下和锤下,只不过锤下后需要快速回到未锤下的状态。具体来说,代码实现如下:
类锤(pygame.sprite.Sprite):
def __init__(self,image_paths,position,**kwargs):
py game . sprite . sprite . _ _ init _ _(self)
self . images=[py game . image . load(image _ paths[0]),py game . image . load(image _ paths[1])]
self.image=self.images[0]
self.rect=self.image.get_rect()
self . mask=py game . mask . from _ surface(self . images[1])
self.rect.left,self.rect.top=position
#用于显示锤击时的特殊效果。
self.hammer_count=0
self.hammer_last_time=4
self.is _ hammering=False
设置位置
定义设定位置(自身,位置):
self . rect . centex,self.rect.centery=pos
设置锤击
def set hamming(self):
self.is _ hammering=True
显示在屏幕上
定义绘制(自身,sc
reen):
if self.is_hammering:
self.image = self.images[1]
self.hammer_count += 1
if self.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def initGame():
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)
return screen
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while True:
# --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
if time_remain == 40:
pygame.time.set_timer(change_hole_event, 650)
elif time_remain == 20:
pygame.time.set_timer(change_hole_event, 500)
# --倒计时音效
if time_remain == 10:
audios[count_down].play()
# --游戏结束
if time_remain < 0: break
count_down_text = font.render(Time: +str(time_remain), True, cfg.WHITE)
# --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)
# --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
# --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
if your_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def startInterface(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]
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
elif event.type == pygame.MOUSEMOTION:
mouse_pos = pygame.mouse.get_pos()
if mouse_pos[0] in list(range(419, 574)) and mouse_pos[1] in list(range(374, 416)):
begin_image = begin_images[1]
else:
begin_image = begin_images[0]
elif event.type == pygame.MOUSEBUTTONDOWN:
if event.button == 1 and mouse_pos[0] in list(range(419, 574)) and mouse_pos[1] in list(range(374, 416)):
return True
screen.blit(begin_image, (0, 0))
pygame.display.update()
结束界面
def endInterface(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_rect()
your_score_rect.left, your_score_rect.top = (screensize[0] - your_score_rect.width) / 2, 215
best_score_text = font.render(Best Score: %s % score_info[best_score], True, font_colors[1])
best_score_rect = best_score_text.get_rect()
best_score_rect.left, best_score_rect.top = (screensize[0] - best_score_rect.width) / 2, 275
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
elif event.type == pygame.MOUSEMOTION:
mouse_pos = pygame.mouse.get_pos()
if mouse_pos[0] in list(range(419, 574)) and mouse_pos[1] in list(range(374, 416)):
again_image = again_images[1]
else:
again_image = again_images[0]
elif event.type == pygame.MOUSEBUTTONDOWN:
if event.button == 1 and mouse_pos[0] in list(range(419, 574)) and mouse_pos[1] in list(range(374, 416)):
return True
screen.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~
