Question

我创建了一个方法＆＃34; getDamage＆＃34;，它应该返回角色的基础伤害，或者他分配给它的武器的伤害（如果有的话）并给他增加基础伤害

＆＃13;

 function Weapon(name,damage) { // properties of weapons
        this.name = name;
        this.damage = damage;
    }
    Weapon.prototype.toString = function () {
        return this.name + this.damage + " damage"; // method to show weapon
    };
    var bow = new Weapon('Golden bow, ', 20); // create weapon 
    function Character() {
        this.health = 100;
        this.basicDamage = 10; 
        this.toString = function () {
            return this.name + this.weapon + this.heroDamage; // show hero his weapon and stack damage
        };
    Character.createArcher = function () { // create hero 
        var hero = new Character;
        hero.name = "Legolas";
        return hero;
    };
  Character.prototype.setWeapon = function (weapon) {
        var me = this;
        me.weapon = weapon; // contact with weapon
        return me;
    };
    Character.prototype.getDamage = function (heroDamage) {
    var stack = this.basicDamage + this.damage;
    stack.heroDamage = heroDamage;
    return stack;
};
    var archer = new Character.createArcher();
    archer.setWeapon(bow); // set the selected weapon
    console.log(archer.toString());

var bow = new Weapon('Golden bow, ', 20);

bow.toString(); //output: "Golden bow, 20 damage"

var archer = new Character();

archer.createArcher('Legolas');

archer.setWeapon(bow);

archer.getDamage(archer.weapon); //output: 30

archer.toString();
//output: "LegolasGolden bow, 30"
