Question

这是一个非常简单的面向对象的javascript游戏的开始。我无法将玩家添加到Games player []数组中。怎么办呢？

我删除了与问题无关的所有代码

var BobsGame = function(){
this.Players = [];
}

BobsGame.prototype.addPlayer = function(Player){
//not working
Player.Game = this;
this.Players.push(Player);
Player.setId = function(this.Players.length) {
    return this.Players.length;
}
return this;
}

var Player = function(name){
this.Game = null;
this.score = 0;
this.name = name;
this.id = null;
//  return alert('Player ' + this.name + ' has been created');
}

var myGame = new BobsGame();

var Player1 = new Player("Tom");
var Player2 = new Player("Bob");

myGame.addPlayer(Player1);

我认为你在尝试：

var BobsGame = function () {
    this.Players = [];
};

BobsGame.prototype.addPlayer = function (Player) {
    this.Players.push(Player);
    Player.id = this.Players.length;
    return this;
};

var Player = function (name) {
    this.score = 0;
    this.name = name;
    this.id = null;
    //  return alert('Player ' + this.name + ' has been created');
};

var myGame = new BobsGame();

var Player1 = new Player("Tom");
var Player2 = new Player("Bob");

myGame.addPlayer(Player1);

错误在以下代码中：

Player.setId = function(this.Players.length) {
    return this.Players.length;
}

在这里，您尝试创建一个名为setId的函数，但不能将this.Players.length定义为参数。因此，假设您尝试将播放器的ID设置为播放器阵列的长度，您可以像这样简单地分配：

Player.id = this.Players.length;

顺便说一下，我建议您不要调用addPlayer“Player”的参数，因为这会隐藏已定义的函数Player。您可能希望将其重命名为“player”。
