前言
坦克大战是一款策略类的平面射击游戏，于 1985 年由 Namco 游戏公司发布，尽管时至今日已经有了很多衍生类的游戏，但这款游戏仍然受到了相当一部分人的欢迎，本文我们看一下如何使用 Python 来实现这款游戏，游戏实现主要用到的 Python 库为 pygame。
简介
坦克大战的组成主要包括：场景、坦克、子弹、食物、大本营，其本质就是一个塔防类的游戏，游戏目标为：守住大本营并且消灭敌方坦克，通常支持单双人模式，下面我们来看一下具体实现。
实现
首先，我们来实现游戏场景，场景的组成主要包括：石头墙、钢墙、冰、河流、树、地图，我们暂时做两个关卡，代码实现如下：
# 石头墙
class Brick(pygame.sprite.Sprite):
def __init__(self):
pygame.sprite.Sprite.__init__(self)
self.brick = pygame.image.load('images/scene/brick.png')
self.rect = self.brick.get_rect()
self.being = False
# 钢墙
class Iron(pygame.sprite.Sprite):
def __init__(self):
pygame.sprite.Sprite.__init__(self)
self.iron = pygame.image.load('images/scene/iron.png')
self.rect = self.iron.get_rect()
self.being = False
# 冰
class Ice(pygame.sprite.Sprite):
def __init__(self):
pygame.sprite.Sprite.__init__(self)
self.ice = pygame.image.load('images/scene/ice.png')
self.rect = self.ice.get_rect()
self.being = False
# 河流
class River(pygame.sprite.Sprite):
def __init__(self, kind=None):
pygame.sprite.Sprite.__init__(self)
if kind is None:
self.kind = random.randint(0, 1)
self.rivers = ['images/scene/river1.png', 'images/scene/river2.png']
self.river = pygame.image.load(self.rivers[self.kind])
self.rect = self.river.get_rect()
self.being = False
# 树
class Tree(pygame.sprite.Sprite):
def __init__(self):
pygame.sprite.Sprite.__init__(self)
self.tree = pygame.image.load('images/scene/tree.png')
self.rect = self.tree.get_rect()
self.being = False
# 地图
class Map():
def __init__(self, stage):
self.brickGroup = pygame.sprite.Group()
self.ironGroup = pygame.sprite.Group()
self.iceGroup = pygame.sprite.Group()
self.riverGroup = pygame.sprite.Group()
self.treeGroup = pygame.sprite.Group()
if stage == 1:
self.stage1()
elif stage == 2:
self.stage2()
# 关卡一
def stage1(self):
for x in [2, 3, 6, 7, 18, 19, 22, 23]:
for y in [2, 3, 4, 5, 6, 7, 8, 9, 10, 17, 18, 19, 20, 21, 22, 23]:

self.brick.being = True
self.brickGroup.add(self.brick)
for x in [4, 5, 6, 7, 18, 19, 20, 21]:

self.brick = Brick()

self.brickGroup.add(self.brick)
for x in [12, 13]:
for y in [16, 17]:

self.brickGroup.add(self.brick)
for x, y in [(11, 23), (12, 23), (13, 23), (14, 23), (11, 24), (14, 24), (11, 25), (14, 25)]:

self.iron = Iron()
self.iron.rect.left, self.iron.rect.top = 3 + x * 24, 3 + y * 24
self.iron.being = True
self.ironGroup.add(self.iron)
# 关卡二
def stage2(self):
for x in [2, 3, 6, 7, 18, 19, 22, 23]:
for y in [2, 3, 4, 5, 6, 7, 8, 9, 10, 17, 18, 19, 20, 21, 22, 23]:
self.brick = Brick()
self.brick.rect.left, self.brick.rect.top = 3 + x * 24, 3 + y * 24
self.brick.being = True
self.brickGroup.add(self.brick)
for x in [10, 11, 14, 15]:
for y in [2, 3, 4, 5, 6, 7, 8, 11, 12, 15, 16, 17, 18, 19, 20]:
self.brick = Brick()
self.brick.rect.left, self.brick.rect.top = 3 + x * 24, 3 + y * 24
self.brick.being = True
self.brickGroup.add(self.brick)
for x in [4, 5, 6, 7, 18, 19, 20, 21]:
for y in [13, 14]:
self.brick = Brick()

self.brick.being = True
self.brickGroup.add(self.brick)
for x in [12, 13]:
for y in [16, 17]:
self.brick = Brick()
self.brick.rect.left, self.brick.rect.top = 3 + x * 24, 3 + y * 24
self.brick.being = True
self.brickGroup.add(self.brick)
for x, y in [(11, 23), (12, 23), (13, 23), (14, 23), (11, 24), (14, 24), (11, 25), (14, 25)]:
self.brick = Brick()
self.brick.rect.left, self.brick.rect.top = 3 + x * 24, 3 + y * 24
self.brick.being = True
self.brickGroup.add(self.brick)
for x, y in [(0, 14), (1, 14), (12, 6), (13, 6), (12, 7), (13, 7), (24, 14), (25, 14)]:
self.iron = Iron()
self.iron.rect.left, self.iron.rect.top = 3 + x * 24, 3 + y * 24
self.iron.being = True
self.ironGroup.add(self.iron)
def protect_home(self):
for x, y in [(11, 23), (12, 23), (13, 23), (14, 23), (11, 24), (14, 24), (11, 25), (14, 25)]:
self.iron = Iron()
self.iron.rect.left, self.iron.rect.top = 3 + x * 24, 3 + y * 24
self.iron.being = True
self.ironGroup.add(self.iron)
我们接着看大本营的实现，大本营的实现相对比较简单，其本质就是一个标识物，代码实现如下：
class Home(pygame.sprite.Sprite): def __init__(self): pygame.sprite.Sprite.__init__(self) self.homes = ['images/home/home1.png', 'images/home/home2.png', 'images/home/home_destroyed.png'] self.home = pygame.image.load(self.homes[0]) self.rect = self.home.get_rect() self.rect.left, self.rect.top = (3 + 12 * 24, 3 + 24 * 24) self.alive = True # 大本营置为摧毁状态 def set_dead(self): self.home = pygame.image.load(self.homes[-1]) self.alive = False
再接着看食物的实现，食物主要用来提升坦克能力，如：坦克升级、增加生命等，代码实现如下：
# 食物类 class Food(pygame.sprite.Sprite): def __init__(self): pygame.sprite.Sprite.__init__(self) # 消灭当前所有敌人 self.food_boom = 'images/food/food_boom.png' # 当前所有敌人静止一段时间 self.food_clock = 'images/food/food_clock.png' # 使得坦克子弹可碎钢板 self.food_gun = 'images/food/food_gun.png' # 使得大本营的墙变为钢板 self.food_iron = 'images/food/food_gun.png' # 坦克获得一段时间的保护罩 self.food_protect = 'images/food/food_protect.png' # 坦克升级 self.food_star = 'images/food/food_star.png' # 坦克生命 + 1 self.food_tank = 'images/food/food_tank.png' # 所有食物 self.foods = [self.food_boom, self.food_clock, self.food_gun, self.food_iron, self.food_protect, self.food_star, self.food_tank] self.kind = None self.food = None self.rect = None # 是否存在 self.being = False # 存在时间 self.time = 1000 # 生成食物 def generate(self): self.kind = random.randint(0, 6) self.food = pygame.image.load(self.foods[self.kind]).convert_alpha() self.rect = self.food.get_rect() self.rect.left, self.rect.top = random.randint(100, 500), random.randint(100, 500) self.being = True
再接着看坦克的实现，坦克包括我方坦克和敌方坦克，我方坦克由玩家自己控制移动、射击等操作，敌方坦克实现自动移动、射击等操作，代码实现如下：
# 我方坦克类
class myTank(pygame.sprite.Sprite):
def __init__(self, player):
pygame.sprite.Sprite.__init__(self)
# 玩家编号(1/2)
self.player = player
# 不同玩家用不同的坦克(不同等级对应不同的图)
if player == 1:
self.tanks = ['images/myTank/tank_T1_0.png', 'images/myTank/tank_T1_1.png', 'images/myTank/tank_T1_2.png']
elif player == 2:
self.tanks = ['images/myTank/tank_T2_0.png', 'images/myTank/tank_T2_1.png', 'images/myTank/tank_T2_2.png']
else:
raise ValueError('myTank class -> player value error.')
# 坦克等级(初始0)
self.level = 0
# 载入(两个tank是为了轮子特效)
self.tank = pygame.image.load(self.tanks[self.level]).convert_alpha()
self.tank_0 = self.tank.subsurface((0, 0), (48, 48))
self.tank_1 = self.tank.subsurface((48, 0), (48, 48))
self.rect = self.tank_0.get_rect()
# 保护罩
self.protected_mask = pygame.image.load('images/others/protect.png').convert_alpha()
self.protected_mask1 = self.protected_mask.subsurface((0, 0), (48, 48))
self.protected_mask2 = self.protected_mask.subsurface((48, 0), (48, 48))
# 坦克方向
self.direction_x, self.direction_y = 0, -1
# 不同玩家的出生位置不同
if player == 1:
self.rect.left, self.rect.top = 3 + 24 * 8, 3 + 24 * 24
elif player == 2:
self.rect.left, self.rect.top = 3 + 24 * 16, 3 + 24 * 24
else:
raise ValueError('myTank class -> player value error.')
# 坦克速度
self.speed = 3
# 是否存活
self.being = True

self.life = 3
# 是否处于保护状态
self.protected = False
# 子弹
self.bullet = Bullet()
# 射击
def shoot(self):
self.bullet.being = True
self.bullet.turn(self.direction_x, self.direction_y)
if self.direction_x == 0 and self.direction_y == -1:
self.bullet.rect.left = self.rect.left + 20
self.bullet.rect.bottom = self.rect.top - 1
elif self.direction_x == 0 and self.direction_y == 1:
self.bullet.rect.left = self.rect.left + 20
self.bullet.rect.top = self.rect.bottom + 1
elif self.direction_x == -1 and self.direction_y == 0:
self.bullet.rect.right = self.rect.left - 1
self.bullet.rect.top = self.rect.top + 20
elif self.direction_x == 1 and self.direction_y == 0:
self.bullet.rect.left = self.rect.right + 1
self.bullet.rect.top = self.rect.top + 20
else:
raise ValueError('myTank class -> direction value error.')
if self.level == 0:
self.bullet.speed = 8
self.bullet.stronger = False
elif self.level == 1:
self.bullet.speed = 12

self.rect = self.rect.move(self.speed*-self.direction_x, self.speed*-self.direction_y)
self.direction_x, self.direction_y = random.choice(([0, 1], [0, -1], [1, 0], [-1, 0]))
is_move = False
else:
raise ValueError('enemyTank class -> direction value error.')
if pygame.sprite.spritecollide(self, brickGroup, False, None) \
or pygame.sprite.spritecollide(self, ironGroup, False, None) \
or pygame.sprite.spritecollide(self, tankGroup, False, None):
self.rect = self.rect.move(self.speed*-self.direction_x, self.speed*-self.direction_y)
self.direction_x, self.direction_y = random.choice(([0, 1], [0, -1], [1, 0], [-1, 0]))
is_move = False
if pygame.sprite.collide_rect(self, myhome):
self.rect = self.rect.move(self.speed*-self.direction_x, self.speed*-self.direction_y)
self.direction_x, self.direction_y = random.choice(([0, 1], [0, -1], [1, 0], [-1, 0]))
is_move = False
return is_move
# 重新载入坦克
def reload(self):
self.tank = pygame.image.load(self.tanks[self.kind][self.color]).convert_alpha()
self.tank_0 = self.tank.subsurface((0, 48), (48, 48))
self.tank_1 = self.tank.subsurface((48, 48), (48, 48))
再接着看子弹的实现，子弹的主要属性包括：方向、速度、是否存活、是否为加强版等，代码实现如下：
# 子弹类
class Bullet(pygame.sprite.Sprite):
def __init__(self):
pygame.sprite.Sprite.__init__(self)
# 子弹四个方向(上下左右)
self.bullets = ['images/bullet/bullet_up.png', 'images/bullet/bullet_down.png', 'images/bullet/bullet_left.png', 'images/bullet/bullet_right.png']
# 子弹方向(默认向上)
self.direction_x, self.direction_y = 0, -1
self.bullet = pygame.image.load(self.bullets[0])
self.rect = self.bullet.get_rect()
# 在坦克类中再赋实际值
self.rect.left, self.rect.right = 0, 0
# 速度
self.speed = 6
# 是否存活
self.being = False
# 是否为加强版子弹(可碎钢板)
self.stronger = False
# 改变子弹方向
def turn(self, direction_x, direction_y):
self.direction_x, self.direction_y = direction_x, direction_y
if self.direction_x == 0 and self.direction_y == -1:
self.bullet = pygame.image.load(self.bullets[0])
elif self.direction_x == 0 and self.direction_y == 1:
self.bullet = pygame.image.load(self.bullets[1])
elif self.direction_x == -1 and self.direction_y == 0:
self.bullet = pygame.image.load(self.bullets[2])
elif self.direction_x == 1 and self.direction_y == 0:
self.bullet = pygame.image.load(self.bullets[3])
else:
raise ValueError('Bullet class -> direction value error.')
# 移动
def move(self):
self.rect = self.rect.move(self.speed*self.direction_x, self.speed*self.direction_y)
# 到地图边缘后消失
if (self.rect.top < 3) or (self.rect.bottom > 630 - 3) or (self.rect.left < 3) or (self.rect.right > 630 - 3):
self.being = False
最后，我们看一下程序的主要初始化代码，如下所示：
# 初始化
pygame.init()
pygame.mixer.init()
screen = pygame.display.set_mode((630, 630))
pygame.display.set_caption("TANK")
# 加载图片
bg_img = pygame.image.load("images/others/background.png")
# 加载音效
add_sound = pygame.mixer.Sound("audios/add.wav")
add_sound.set_volume(1)
bang_sound = pygame.mixer.Sound("audios/bang.wav")
bang_sound.set_volume(1)
blast_sound = pygame.mixer.Sound("audios/blast.wav")
blast_sound.set_volume(1)
fire_sound = pygame.mixer.Sound("audios/fire.wav")
fire_sound.set_volume(1)
Gunfire_sound = pygame.mixer.Sound("audios/Gunfire.wav")
Gunfire_sound.set_volume(1)
hit_sound = pygame.mixer.Sound("audios/hit.wav")
hit_sound.set_volume(1)
start_sound = pygame.mixer.Sound("audios/start.wav")
start_sound.set_volume(1)
# 开始界面
num_player = show_start_interface(screen, 630, 630)
# 播放游戏开始的音乐
start_sound.play()
# 关卡
stage = 0
num_stage = 2
# 游戏是否结束
is_gameover = False
# 时钟
clock = pygame.time.Clock()
实现效果
看一下实现效果：
再说一下玩家一、二的操作键，玩家一、二移动键分别为：WASD、←→↑↓，玩家一、二射击键分别为：J、0。
总结
本文我们使用 Python 实现了坦克大战的基本功能，还有待完善，有兴趣的话，可以对游戏做进一步的完善和扩展。
