初学者：无法完成游戏

-2

我正忙于完成这个“穷人”Hang子手，这是我班的一部分。我已经完成了大部分工作，但我有一件事阻止了我完成。初学者：无法完成游戏

我的问题是，我觉得我的

nextGuess = nextGuess.concat(String.valueOf(guess.charAt(i)));

用空格代替我的 “*” 占位符。这个词必须用星号和间隔来掩盖，所以“披萨”将是“* * * * *”。

但是，当有人按下字母时，单词中的某些字符会从游戏区域中消失。有任何想法吗？

这确实应该减少：参见[MCVE] 。 –

它甚至没有格式化好，就像1/5它是无用的空格 – redFIVE

'guess'有更多的字符，然后'currentWord'，但是你试图连接来自'guess'的值到它里面......这是不匹配 – MadProgrammer

这是你的模型/数据与您的演示文稿/视图

guess有更多的字符，那么currentWord混合的经典范例，但你正在尝试基于指数从guess值连接成它currentWord ...不匹配。

相反，我会简单地维持guess和currentWord之间的关系，1-1，所以它们具有相同的字符数，并简单地改变它的显示方式...

所以，当你过叫gameField.setText(guess);你需要先格式化文本，例如gameField.setText(pad(guess));

凡pad可能看起来像......

protected String pad(String value) { 
    StringJoiner sj = new StringJoiner(" "); 
    for (char c : value.toCharArray()) { 
     sj.add(Character.toString(c)); 
    } 
    return sj.toString(); 
}

刚刚injec每个角色之间有一个空格。

这也意味着，当你做到这一点

if (guess.equals(currentWord)) {

事实上，你会得到一个有效的结果（因为不等于pizza：P）

' t似乎使用StringJoiner的构造函数......我会研究为什么。感谢您的建议！ – Remsen

您使用的是Java 8吗？它只适用于Java 8+ – MadProgrammer
