scruffy-shuffle

Lets you deal cards to players giving one an advantage.

installation

node:

$ npm install scruffy-shuffle

component:

$ component install kitto1/scruffy-shuffle

usage

You pass an array of objects and scruffy shuffle will return multiple arrays - one for each player in a game.

Players can be 'weighted' meaning they are dealt higher value objects than other players.

The 'value' of an object can be derived from a property name or a map function.

var shuffle = require('scruffy-shuffle')
 
// our source objects
var objects = [{
    name:'Apple',
    price:12
},{
    name:'Orange',
    price:11
},{
    name:'Pear',
    price:14
},{
    name:'Grape',
    price:9
},{
    name:'Fig',
    price:6
},{
    name:'Peach',
    price:8
}]
 
// the value of each object is its 'price' field
// we want 2 hands where the first hand is twice as good as the second
var hands = shuffle(objects, {
    valueField:'price',
    players:[2,1]
})
 
var betterList = hands[0]
var worseList = hands[1]

api

var hands = shuffle(array, opts)

Shuffle the array of objects into multiple arrays one for each player

The opts object has the following properties:

• size - the number of cards in each players hand (optional)
• valueField - which field of each object represents it value (can be map function)
• players - an array of weightings for each player

The size (if given) is the number of cards for each hand

The valueField can be a string or a function and is used to determine the 'value' of each object

The list of players is a list of relative weighting towards each hand.

If you wanted player 2 to have a 30% better hand than player 1:

[1,1.3]

If you wanted 5 players with an even split:

[1,1,1,1,1]
