如何在 Pygame 中更改游戏中的分数？

【问题标题】：How do I get the score to change in the game in Pygame?如何在 Pygame 中更改游戏中的分数？
【发布时间】：2021-02-18 02:34:13
【问题描述】：

我正在尝试在 PyGame 中制作井字游戏，但是当玩家连续获得三个“x”时，我无法改变分数。每当我运行代码时，游戏开始，我可以放置'x's 和'o's，我可以清除棋盘并关闭窗口，但即使有赢家，分数也不会改变。我希望每个“连续三个”都算作一个点。我想要计算分数，当一名球员得到五分时，他们赢得了整场比赛。我尝试将比分打印到终端，但是在一场胜利之后这些数字就搞砸了，但如果你在两轮之间清除棋盘，那应该不是问题。我也没有收到任何错误，所以我不知道从哪里开始。我用谷歌搜索了如何解决这个问题，但没有任何意义或适合这种情况。

我没有任何东西可以检查 'o's 是否赢了，但我将复制/粘贴带有 'x's 的部分并更改一些内容，以便它也适用于 'o's。

我不知道出了什么问题，所以这是我所有的代码：

【问题讨论】：

  • 您创建了一个名为X_WINS_LABEL 的表面一次，而且只有一次，其内容永远不会改变。 X_WINS 和 X_WINS_LABEL 之间没有神奇的关系。当X_WINS 更新时，没有任何合同约束X_WINS_LABEL 进行更新。每次分数变化时，您都需要创建并显示另一个表面。
  • 仅供参考，您可以只用一行创建一个相同的board_state，使用列表理解：board_state = [[None for a in range(31)] for b in range(31)]。通常，如果您在代码中看到大量重复，在大多数情况下您可能可以使用循环来避免它。

【解决方案1】：

当X_WINS的值发生变化时，你需要更新X_WINS_LABEL，例如

X_WINS += 1
X_WINS_LABEL = main_font.render(f"X = {X_WINS}", True, (0, 0, 0))

事实上，X_WINS_LABEL 被初始化为一个值但从未改变，更新X_WINS 不会导致X_WINS_LABEL 自行更新。

您还可以通过在重绘时生成消息来一起摆脱X_WINS_LABEL var：

WIN.blit(main_font.render(f"X = {X_WINS}", True, (0, 0, 0)), (100, 450))

这会更简洁一些，因为您不必单独管理获胜次数和标签，但您会更频繁地致电main_font.render。根据呈现消息的成本，这可能是一个值得权衡的选择，也可能不值得。

【讨论】：

  • 我把 "X_WINS_LABEL = main_font.render(f"X = {X_WINS}", True, (0, 0, 0)) " 在所有带有 X_WINS += 1 的 if 语句中，它都算在内赢的次数，但是当我试图清除棋盘时，它也会给刚刚得分的人加分。你知道什么可以解决这个问题吗？
  • 看起来您正在检查每个输入的获胜条件，而不仅仅是玩家移动的输入，因此清除棋盘（或进行另一移动）玩家获胜后）也会增加分数。处理此问题的一种方法是跟踪是否有任何玩家赢得了回合，仅检查没有玩家获胜的胜利条件，并将跟踪回合胜利的变量在清除棋盘时设置为 false，当玩家获胜时设置为 true。跨度>
