python - 如何从 if 语句中创建永久更改？

问题描述

我是 python 和一般编码的新手，所以如果我的代码凌乱或杂乱无章，请原谅。我正在创建一个战舰游戏并建立了一个命中系统（白色表示正确猜测，红色表示错误猜测），但是，我似乎无法使更改永久化，我希望按下空格按钮时的颜色并且您的猜测块停留在该坐标中。

控制是 WASD 移动和 SPACE 开火。

任何帮助是极大的赞赏

这是我的代码：

解决方案

如果问题与此有关：“我似乎无法使更改永久化”

然后，您需要将有关此信息的信息存储到数据文件中。

您可以从文本文件开始（或使用搁置 python 模块）。这个 python 模块有一个名为 shelve.open() 的函数，它返回一个“架子文件对象”，可用于创建、读取和写入数据到硬盘驱动器上的架子文件。您可以使用任何 python 模块（例如：用于数据库方式的 sqlite）。

只需创建一个新的 hit_coord_xy 并在每次按下文件时保存此坐标：

注意：使用 hitcoorx 和 hitcoory 对于存储数据不是很好（在测试或调试项目时更快）我为每个按键使用一个函数/方法（对象）并解决它，让我们看一个简单的例子：

if keys[pygame.K_a] and x>0:
    x = x - 1
    y =0
    hit_air = true
    hit_water = false
    hitcoord_point[x, y, hit_air, hit_water]

并像这样解决：

如果 x,y 进入 hitcoorx , hitcoory , hit_air 为真，则敌人会被空中击中并造成 air_damage ...

您需要创建一个结构数据，其中包含命中/非命中、hit_water、hit_air、可能命中数等的坐标和值。

游戏中的每个对象都将允许使用这些数据来显示命中、得分和对游戏进行更改。

您的代码很简单，但您可以为每个对象使用类，例如：玩家、地图。源代码简短且易于维护的主要原因。
