score.js

A small javascript module to add levels, checkpoints and badges to a linear score.

See the demo or read an introduction

Quick usage

var score = new Score();
 
// set score
score.set(123);
 
// increase score by 1
score.increment();
 
// increase score by 10
score.increment(10);
 
// decrease score by 1
score.decrement();
 
// get scorecard
score.scorecard();

scorecard returns...

{
    score:123						// current total score
    title:"Gorilla",				// current title
    quote:"You're a true soldier"	// current quote
    level:2,						// current level
    levelscore:23,					// current level score
    leveltotal:200,					// current level total
    levelprogress:11.51, 			// percentage %
    totalprogress:34.45, 			// percentage %
    levelup: false,					// did we just level up?
    totallevels:10 					// total levels
    prestige:0 						// prestige level see below
}

lib/score.js comes with 10 levels as default. lib/score-basic.js comes with none. The default levels can be replaced with custom levels using the setup below.

Setup

var score = new Score(
    {
        persistant:true				// uses localStorage -  default: true
        callback:function(){...}	// callback when levelling up
        levels: 					// custom levels
        [							
            {
                "checkmark": 0,
                "status": "noob",
                "quote": "You're just a little newbie"
            }, 
            {
                "checkmark": 500,
                "status": "champion",
                "quote": "You're halfway there"
            }, 
            {
                "checkmark": 1000,
                "status": "legend",
                "quote": "You made it!"
            }
        ]
    }
);

Multipliers

Handy when you want to give your user double or triple points for a given duration.

// multiply all increments and decrements by 2 from now on
score.multiplier(2);
 
// multiply all increments and decrements by 3 for the next 5 seconds
score.multiplier(3, 5000);
 
// multiply all increments and decrements by 4 for the next 5 seconds 
// with a callback
score.multiplier(4, 5000, function(){ ... });

Prestige levels

To provide an infinite score, you can allow your players to reset their score after completing all levels.

score.prestige();

This resets the score to 0 and increments scorecard.prestige. This only works if scorecard.totalprogress is 100%.
