*-FACTORIES

10; } var WaterFairy = function() { this.hp = 4; this.damage = 6; } var fox = new Fox(); var waterFairy = new WaterFairy();
var Monster = function(attrs) { // Set attrs } var
fox = new Monster({ hp: 4, damage: 6 });
None
var MonsterFactory = function(csv) { this.data = createMap(csv); } MonsterFactory.prototype.create(type)
{ var attrs = this.data[type]; return new Monster(attrs); }
// During game initialization factory = new MonsterFactory(csv); // And
then later factory.create("fox");
