Introduction

A collection of unique elements, built-in data structure of phaser.

• Author: Richard Davey

Usage

Create instance

var set = new Phaser.Structs.Set();

or

var set = new Phaser.Structs.Set(elements);

Add an element

set.set(element);

Remove an element

set.delete(element);

Remove all elements

set.clear();

Has element

set.contains(element);

Get elements

var elements = set.entries;

or get a shallow copy of elements

var elements = set.getArray();

Element counts

var size = set.size;

For each element

• For when you know this Set will be modified during the iteration.

  set.each(function(element, index) {
      // return false;  // return false to cancel iteration
  }, scope)
  

• For when you absolutely know this Set won't be modified during the iteration.

  set.iterate(function(element, index) {
      // return false;  // return false to cancel iteration
  }, scope)
  

Set operations

• C = A | B

  var setC = setA.union(setB);
  

• C = A & B

  var setC = setA.intersect(setB);
  

• C = A - B

  var setC = setA.difference(setB);
