我正在构建的这个刽子手游戏遇到了问题。我添加了基本功能，这样如果您没有猜出正确的字母，则guessNumber 变量就会减一。我当前代码遇到的问题是，当玩家猜到错误的字母时，它会完全退出 while 循环。我是否正在构建 while 循环或 guessNumber--; 的定位？我已经对这段代码进行了大约一个小时的修改，但仍然无法弄清楚!

最佳答案
每次循环找不到该字母时，您都会递减 guessNumbers。 guessNumbers-- 需要位于循环之外，因此每次输入只会减少一次猜测数。
// array of words
var words = [
"trajectory", "symphony", "desire", "antfarm", "dancer", "happiness", "positioning",
"hobbit", "obituary", "cheetah", "sunrise", "antithesis", "wrong", "diamonds",
"partnership", "oblique", "sanctuary"];
// pick a random word
var word = words[Math.floor(Math.random() * words.length)];
// set up the answer array
var answerArray = [];
for (var i = 0; i < word.length; i++) {
answerArray[i] = "_";
}
var remainingLetters = word.length;
//amount of guesses
var guessNumber = 5;
//the game loop
