DESIGN PATTERNS
COMPOSE EVERYTHING
None
Crafty.c("Walkable", { Walkable: function(speed) { this.addComponent("Collision"); this.bind("EnterFrame", function() { if
(paused()) return; if (obstacle() || outOfBounds()) return; // Move the sprite this.playAnimation(this.direction); this.move(this.direction, speed); })
Crafty.c("StrollingEntity", { StrollingEntity: function() { this.direction = randomDirection(); this.bind("EnterFrame", function()
{ // Possibly change direction if (chanceToSwitchDirection()) { this.direction = randomDirection(); } } } });
spawnedMonster .Walkable(5) .StrollingEntity() .Battleable()
Crafty.c("AggroEntity", { AggroEntity: function(player) { this.direction = randomDirection(); this.bind("EnterFrame", function()
{ if (playerInRange()) { this.direction = toPlayer(player); } else if (chanceToSwitchDirection()) { // Change direction this.direction = randomDirection(); } } } });

*-FACTORIES
var Fox = function() { this.hp = 10; this.damage =
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");
