Lucy forge

Part of lucidity project.

Beta software. Until 1.0, API subject to change.

Entity and component definition tool

lucy.forge is a minimal 'game' or 'feature composition' engine. It's goal is to foster clean and reusable Javascript code through the extensive use of mixins and conventions.

Installation

npm install lucy-forge --save

Usage example:

const forge = require ( 'lucy-forge' )

// Define a component
// for auto-loading, the path for this component should be 'Person.js'
const Person = forge.Component
( 'Person'
  // Class methods
, { // Setup an entity. 'e' is the entity being initialized.
    setup ( e )
    { e._person = {}
      Person.people.push ( e )

      e.bind
      ( 'destroy'
      , function ()
        { Person.peopleCount --
        }
      )
    }

    // This is called once on Component creation. It is used to initialize
    // the component (not an entity). 'this' is the component aka 'class'.
    // Here, this === Person.
  , init ()
    { this.peopleCount = 0
    }

  , count ()
    { return this.peopleCount
    }
  }

  // Methods
, { person ( name, age )
    { let self = this._person
      self.name = name
      self.age  = age
    }
  }
)

// Use the component
let Person = forge.findComponent ( 'Person' )

console.log
( Person.count () ) // ==> 0

let player1 = forge.Entity
( 'Person'
, 'Score'
  // #set shortcut
  // same as calling player1.person ( 'John Difool', 34 )
  //                 player1.score  ( 100 )
, { person: [ 'John Difool', 34 ]  
  , score: 100
  }
)

console.log
( Person.count () ) // ==> 1
