问题描述
我正在尝试在 PyGame 中制作井字游戏，但是当玩家连续得到三个“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”和“o”，我可以清除棋盘并关闭窗口，但是即使有赢家，分数也不会改变。我希望每个“连续三个”都算作一个点。我想要积分，当一个球员得到五分时，他们就赢得了整场比赛。我尝试将分数打印到终端，但是在一场胜利后这些数字就搞砸了，但是如果您在几轮之间清除棋盘，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。我在谷歌上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。
我没有任何检查 'o's 是否获胜，但我只是复制/粘贴带有 'x's 的部分并更改一些内容，使其也适用于 'o's。
我不知道出了什么问题，所以这是我的所有代码：

解决方法
当 X_WINS 的值发生变化时，您需要更新 X_WINS_LABEL，例如
X_WINS += 1
X_WINS_LABEL = main_font.render(f"X = {X_WINS}",True,(0,0))
实际上，X_WINS_LABEL 是用一个值初始化但从未更改过，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消除 X_WINS_LABEL 变量：
WIN.blit(main_font.render(f"X = {X_WINS}",0)),(100,450))
这样会更简洁一些，因为您不必独立管理获胜次数和标签，但您会更频繁地调用 main_font.render。根据呈现消息的成本，这可能是也可能不是值得的权衡。
