利用python3 的pygame模块实现塔防游戏

Python  /  管理员 发布于 7年前   222

利用python3的pygame模块基本实现塔防游戏的基本功能，包括血量和分数显示，bgm，防御塔建造，防御塔攻击范围内的敌军，暂停和加速功能。由于实在没有素材，用的都是自己截图P的，所以美化不好。但基本保证功能，其中有一个BUG，但不影响游戏效果。

3.敌军类

4.炮塔建造位置类

"""初始化炮塔可占据的位置"""import pygameclass Position(pygame.sprite.Sprite):  """pos"""  def __init__(self, pos):    pygame.sprite.Sprite.__init__(self)    self.image = pygame.image.load('image/pt.png')    self.rect = self.image.get_rect()    self.rect.left, self.rect.top = pos

5.说明

本游戏通过鼠标左键点击炮塔可以建造的位置俩建造炮塔。

6.效果图

可以看到图确实不好看，但美术功底不够，所以不怎么好看。当然需要素材的也可以给你。
