APCSP创建任务问题-方法在被调用后结束程序



我正在为我的AP CSP项目创建一个简短的RPG游戏，出于某种原因，当我在第310-313行调用方法Element时，它只是结束了Main中的其余代码(这是程序中所有剩余的代码(。用户需要按x键才能继续游戏，但它会跳过所有这些并自动正确填充用户输入。简而言之，一旦你在代码中选择了元素，程序就会自己完成游戏，这是不应该发生的，因为用户需要输入才能继续对话。

如上所述，该代码的预期输出是仅使用用户输入和用户信息来完成对话。请帮忙，因为这很快就要到期了！

看起来您停止了遵循一开始应用的模式。如您所见，在第310行之前，您已使用

play = scan.nextLine();
if (play.charAt(0) == 'x' )

在检查字符之前，调用扫描仪读取新行。在第310行之后，您已经停止使用play = scan.nextLine();，这意味着程序不会停止等待用户输入，而是将继续，因为player.charAt(0)将始终等于x(或之前的输入(。

查找所有检查字符输入的实例，并确保已调用nextLine()

编辑：

作为一个不得不标记大学一年级项目的人，这只是一句建议。

  • 考虑将对话存储在数组中(尤其是在对话非常线性的情况下(，然后使用while循环对其进行迭代。查找Java的行分隔符
  • 考虑当用户不按"；x〃；以及如何正确处理
  • 添加一些开发人员对你为什么以某种方式做某事的评论
  • 查找DRY的概念(不要重复(，并寻找以这种方式改进代码的方法
