# laro.js

Yet another Entity-Component-System game micro-framework in JavaScript. Only
this time, written in ES6. It also auto-generates a documentation page of your
code if you write them in jsdoc syntax in your actual code.

Goals
=====

- To provide a sustainable design pattern for writing large, complex and ambitious HTML5 JavaScript games
- To be easy to integrate with other JavaScript frameworks.
- To provide a deterministic architecture that can be used for server-side logic

Installation
============

- `npm install laro --save`

Basic Usaage
============

```javascript
import laro from 'laro'
import StatsComponent from './components/StatsComponent'
import CharacterComponent from './components/CharacterComponent'
import CombatComponent from './components/CombatComponent'
import CombatSystem from './systems/CombatSystem'

/*
  A world object ties the entities and systems together
 */
let world = new laro.World()

/*
  We register pre-defined component classes in our game world to be instantiated
  and used later by generated entities.
 */
world.components
  .register(StatsComponent)
  .register(CharacterComponent)
  .register(CombatComponent)

/*
  A System object handles different kinds of logic.
 */
world.register(CombatSystem, [ StatsComponent, CombatComponent ])

/*
  Creating an entity can be configured from a .json file.

  file: ./data/entities/hero.json

  {
    "stats": { "hp": 100, "atk": 100, "def": 30 }
    "character": { "name": "Hitomi", "type": "hero"},
    "player": true,
    "combat": true
  }

  file: ./data/entities/monster.json

  {
    "stats": { "hp": 100, "atk": 10, "def": 0 }
    "character": { "name": "Bakemono", "type": "hero"},
    "combat": true
  }
 */

let hero = world.addEntity(require('./data/entities/hero.json'))
let monster = world.addEntity(require('./data/entities/monster.json'))

/*
  You can expose and call functions of your component.
 */

hero.components.combat.setTarget(monster)

/*
  Updates are ticks that advances the frame of the game. All system logic
  are executed.
 */

world.update(1)

console.log(monster.components.stats.attribute.health.isEmpty()) // => true
console.log(monster.components.character.name) // => Bakemono
console.log(monster.components.character.type) // => monster
```

Design Patterns
===============

- Components are data. Extend `laro.Component` as your base class
- Systems are the logic. Extend `laro.System` as yoru base class
- Entities are just component containers with a basic API for attaching and detaching them.
