JavaScript 骰子游戏返回 0

Question

Stack Overflow 上有很多关于 JavaScript 骰子游戏的帖子，但我找不到能回答我问题的帖子。此代码改编自 CodeCademy:

function rollSingleDice() {
    return Math.floor(Math.random()*6+1);
}

function rollDice(player) {
var score = 0;
var roll1; var roll2;
var playerScore = player.getScore();
    do {
        roll1 = rollSingleDice();
        roll2 = rollSingleDice();
    } while (roll1 === roll2);

    score = roll1 + roll2;
    player.addToScore(score);

    if (roll1 === roll2) {
        console.log(player.name + "'s current score is: " +
        playerScore);
    } else {
        console.log(player.name + "'s current score is: " +
        playerScore);
    }
   // return score;
}


function Player(name) {
  this.name = name;
  var score = 0; // this is a private attribute
  this.addToScore = function(points) {
    score = score + points;
  };
  this.getScore = function() {
    return score;
  };
}

var player1 = new Player("Bobby");
rollDice(player1);

我已经多次修改 do ... while 循环，我得到的唯一输出如下:

Bobby 的当前分数是:0

有人可以指出我正确的方向吗？谢谢。

您获取玩家得分的值并将其保存在“playerScore”变量中。但是，之后您不会更新该值，因此当您稍后点击 console.log() 语句时，它仍然具有其原始值。更改 console.log 调用，以便它记录在播放器上调用 .getScore() 的结果。

    console.log(player.name + "'s current score is: " + player.getScore());
