Welcome to Phaser and What's new in 2.0.5?

We've had the vast majority of this version ready for a few days now, but held off releasing due to Ludum Dare 48. Ludum Dare contests are always peak times for Phaser, we see an influx of new devs downloading for the first time. So it's not the best day to release a new version :) Now that LD48 has finished we present Phaser 2.0.4. This is the latest version in our bi-weekly sprint release schedule, and the change log is (which you can see in full below) is significant to say the least.

We've made some deep internal changes to how game pause and resume is handled, which means Phaser.Timers now behave themselves properly. Again with this version we've updated to the latet Pixi and P2 releases, bringing new features and enhancements with them. In terms of new features we've overhauled the Color, Point and BitmapData classes, with significant new features for each of them. From HSL palette shifting and color extraction, to Point dot products to proper endianess handling in Color, the new features are powerful additions to the library. We've also marked a bunch of methods as deprecated and will remove them in Phaser 2.1. Most have fully working replacements and you'll see them flagged as such in the API docs.

Thanks to traffic from Ludume Dare and some great new sites, we've seen Phaser sky rocket on github; now clearing 4325 github stars and 1175 forks. In most cases issues are being resolved fast and we're closing over 97% of all those reported, which we're extremely proud about.

For the 2.0.5 release we're going to be looking carefully at CocoonJS support, there are some known issues with it currently and we want to ensure it works as flawlessly as possible. After this we'll start planning for 2.1.

We're also very close to releasing the brand new Phaser web site. The current single-page site has done us well for now, but it was only ever meant to be temporary while the full site was built. This is nearly done and we've got some exciting content to share and plenty of room for growth! Be sure to subscribe to our monthly newsletter to be notified as soon as it's out.

Until then happy coding everyone! And we hope to see you on the forums.

Getting Started Guides

We have a Getting Started Guide which covers all you need to begin developing games with Phaser. From setting up a web server to picking an IDE. If you're new to HTML5 game development, or are coming from another language like AS3, then we recommend starting there.

We wrote a comprehensive How to Learn Phaser guide for GameDevTuts+ which covers finding tutorials, examples and support.

The Game Mechanic Explorer is a great interactive way to learn how to develop specific game mechanics in Phaser. Well worth exploring once you've got your dev environment set-up.

Finally the list of community authored Phaser Tutorials is growing fast!

Change Log

Version 2.0.5 - "Tanchico" - in development

Updates

• TypeScript definitions fixes and updates (thanks @luispedrofonseca @clark-stevenson @Anahkiasen @adamholdenyall)
• Input.getPointerFromIdentifier docs update to reflect where the identifier comes from. Pointer properties now set to give it fixed defaults (thanks @JirkaDellOro, #793)
• Pointer.pointerId added which is set by the DOM event (if present in the browser). Note that browsers can and do recycle pointer IDs.
• Pointer.type and Pointer.exists properties added.
• QuadTree.retrieve can now accept either a Sprite with a physics body or a Phaser.Rectangle as its parameter.
• PluginManager.add now accepts additional parameters and if given a function it will pass them all to the Plugin constructor.
• Tilemap.getTile has a new nonNull parameter. If true it won't return null for empty tiles, but will return the actual Tile in that location.

New Features

• New force parameter added to Group.set, setAll, setAllChildren, setProperty which controls if a property is created even if it doesn't exist.
• Group.hasProperty will check a child for the given property and return a boolean.
• Phaser.Tween.from allows you to set tween properties that will end up where the current object is (thanks @codevinsky, #792)
• Input.getPointerFromId will return a pointer with a matching pointerId value, if any. pointerId is a value set by the browser in the DOM event.
• ArcadePhysics.getObjectsUnderPointer will return all children from a Group that overlap with the given Pointer.
• InputManager.minPriorityID lets you set the minimum priority level an object needs to be to be checked by a Pointer. Useful for UI layer stacking.
• New consts: Phaser.Tilemap.NORTH, SOUTH, EAST and WEST to use with the TileMapWalker Plugin.
• BitmapData.processPixelRGB added undefined check (thanks @muclemente, fix #808)
• Phaser.Utils.transposeArray will transpose the given array and return it.
• Phaser.Utils.rotateArray will rotate the given array by 90 or 180 degrees in either direction and return it.

New Plugins

• TilemapWalker allows you to set a location marker into a tilemap. You can then move around with commands such as moveForward, turnLeft, etc.

Bug Fixes

• Line.pointOnLine corrected algorithm (thanks @woutercommandeur, fix #784)
• Line segment collision fails under certain cicumstances (thanks @woutercommandeur, fix #760)
• The P2 DistanceConstraint method signature has changed. Updated Phaser so maxForce is now passed as object (fix #788)
• Moved the this._reversed flag outside of the property loop in Tween (as per tween.js issue 115)
• Emitter.makeParticles updated to use Array.isArray() check on the key/frame values, so non-string objects can be passed in (thanks @AnderbergE, fix #786)
• Tilemap.createFromObjects will now force the creation of the property again even if it doesn't exist (regression fix from 2.0.4)
• Phaser.Line.intersectsPoints fixed by properly checking the boundaries (thanks @woutercommandeur, fix #790)
• Group.set and setAll were changed in 2.0.4 to not create the property unless it existed. This broke backwards compatibility, so has been fixed.
• Sound.play now returns the Sound object (thanks @AnderbergE, fix #802)

P2.Body.collideWorldBounds = true fails.

There is an extensive Migration Guide available for those converting from Phaser 1.x to 2.x. In the guide we detail the API breaking changes and approach to our new physics system.

How to Build

We provide a fully compiled version of Phaser in the build folder, in both plain and minified formats.

You will also find custom builds in the build\custom folder, that split phaser up into components.

We also provide a Grunt script that will build Phaser from source.

Run grunt to perform a default build to the dist folder.

If you replace Pixi or p2 then run grunt replace to patch their UMD strings so they work properly with Phaser and requireJS.

Note: Some of you may not be aware, but the phaser.min.js file in the build folder contains all 3 physics systems bundled in. If you only need Arcade Physics then you can use build\custom\phaser-arcade-physics.min.js instead. This will save you 180KB from the minified file size.

Koding

You can and then start editing and previewing code right away using their web based VM development system.

Bower

If you use bowser you can install phaser with:

bower install phaser

Nice and easy :)

CDNJS

Phaser is now available on CDNJS. You can include the following in your html:

http://cdnjs.cloudflare.com/ajax/libs/phaser/2.0.5/phaser.min.js

Or if you prefer you can leave the protocol off, so it works via http and https:

//cdnjs.cloudflare.com/ajax/libs/phaser/2.0.5/phaser.min.js

Requirements

Games created with Phaser require a modern web browser that supports the canvas tag. This includes Internet Explorer 9+, Firefox, Chrome, Safari and Opera. It also works on mobile web browsers including stock Android 2.x browser and above and iOS5 Mobile Safari and above. But as always be aware of browser limitations. Not all features of Phaser work on all browsers.

IE9

If you need to support IE9 or Android 2.x and want to use P2 physics then you must use the polyfill found in the resources/IE9 Polyfill folder. If you don't require P2 Physics (or don't care about IE9!) then you don't need this polyfill.

JavaScript and TypeScript

Phaser is developed in JavaScript. We've made no assumptions about how you like to code your games, and were careful not to impose any form of class / inheritance / structure upon you. So you won't find it split into require modules or pull in 3rd party npm packages for example. That doesn't mean you can't, it just means we don't force you to do so. If you're a requireJS user you'll find a new template in the resources\Project Templates folder just for you.

If you code with TypeScript you'll find a comprehensive definitions file inside the build folder and tutorials on getting started.

Phaser is 128 KB gzipped (576 KB minified) when including all 3 physics engines. Without the physics engines its 67 KB gzipped (311 KB minified)

Note: The phaser.min.js file in the build folder contains all 3 physics systems bundled in. If you only need Arcade Physics then you can use build\custom\phaser-arcade-physics.min.js instead. This will save you 180 KB from the minified file size.

Learn By Example

Ever since we started Phaser we've been growing and expanding our extensive set of Examples. Currently over 270 of them!

They used to be bundled in the main Phaser repo, but because they got so large and in order to help with versioning we've moved them to their own repo.

So please checkout https://github.com/photonstorm/phaser-examples

Here you'll find an ever growing suite of Examples. Personally I feel that developers tend to learn better by looking at small refined code examples, so we created hundreds of them, and create new ones to test new features and updates. Inside the examples repo you'll find the current set. If you write a particularly good example then please send it to us.

The examples need to be run through a local web server (in order to avoid file access permission errors from your browser). You can use your own web server, or start the included web server using grunt.

Using a locally installed web server browse to the examples folder:

examples/index.html

Alternatively in order to start the included web server, after you've cloned the repo, run npm install to install all dependencies, then grunt connect to start a local server. After running this command you should be able to access your local webserver at http://127.0.0.1:8000. Then browse to the examples folder: http://127.0.0.1:8000/examples/index.html

There is a 'Side View' example viewer as well. This loads all the examples into a left-hand frame for faster navigation. And if you've got php installed into your web server you may want to try debug.php, which provides a minimal examples list and debug interface.

You can also browse all Phaser Examples online.

Features

WebGL & Canvas

Phaser uses both a Canvas and WebGL renderer internally and can automatically swap between them based on browser support. This allows for lightning fast rendering across Desktop and Mobile. When running under WebGL Phaser now supports shaders, allowing for some incredible in-game effects. Phaser uses and contributes towards the excellent Pixi.js library for rendering.

Preloader

We've made the loading of assets as simple as one line of code. Images, Sounds, Sprite Sheets, Tilemaps, JSON data, XML and JavaScript files - all parsed and handled automatically, ready for use in game and stored in a global Cache for Sprites to share.

Physics

Phaser ships with our Arcade Physics system, Ninja Physics and P2.JS - a full body physics system. Arcade Physics is for high-speed AABB collision only. Ninja Physics allows for complex tiles and slopes, perfect for level scenery, and P2.JS is a full-body physics system, with constraints, springs, polygon support and more.

Sprites

Sprites are the life-blood of your game. Position them, tween them, rotate them, scale them, animate them, collide them, paint them onto custom textures and so much more! Sprites also have full Input support: click them, touch them, drag them around, snap them - even pixel perfect click detection if needed.

Groups

Group bundles of Sprites together for easy pooling and recycling, avoiding constant object creation. Groups can also be collided: for example a "Bullets" group checking for collision against the "Aliens" group, with a custom collision callback to handle the outcome.

Animation

Phaser supports classic Sprite Sheets with a fixed frame size, Texture Packer and Flash CS6/CC JSON files (both Hash and Array formats) and Starling XML files. All of these can be used to easily create animation for Sprites.

Particles

An Arcade Particle system is built-in, which allows you to create fun particle effects easily. Create explosions or constant streams for effects like rain or fire. Or attach the Emitter to a Sprite for a jet trail.

Camera

Phaser has a built-in Game World. Objects can be placed anywhere within the world and you've got access to a powerful Camera to look into that world. Pan around and follow Sprites with ease.

Input

Talk to a Phaser.Pointer and it doesn't matter if the input came from a touch-screen or mouse, it can even change mid-game without dropping a beat. Multi-touch, Mouse, Keyboard and lots of useful functions allow you to code custom gesture recognition.

Sound

Phaser supports both Web Audio and legacy HTML Audio. It automatically handles mobile device locking, easy Audio Sprite creation, looping, streaming and volume. We know how much of a pain dealing with audio on mobile is, so we did our best to resolve that!

Tilemaps

Phaser can load, render and collide with a tilemap with just a couple of lines of code. We support CSV and Tiled map data formats with multiple tile layers. There are lots of powerful tile manipulation functions: swap tiles, replace them, delete them, add them and update the map in realtime.

Device Scaling

Phaser has a built-in Scale Manager which allows you to scale your game to fit any size screen. Control aspect ratios, minimum and maximum scales and full-screen support.

Plugin system

We are trying hard to keep the core of Phaser limited to only essential classes, so we built a smart Plugin system to handle everything else. Create your own plugins easily and share them with the community.

Mobile Browser

Phaser was built specifically for Mobile web browsers. Of course it works blazingly fast on Desktop too, but unlike lots of frameworks mobile was our main focus. If it doesn't perform well on mobile then we don't add it into the Core.

Developer Support

We use Phaser every day on our many client projects. As a result it's constantly evolving and improving and we jump on bugs and pull requests quickly. This is a living, breathing framework maintained by a commercial company with custom feature development and support packages available. We live and breathe HTML5 games.

Battle Tested

Phaser has been used to create hundreds of games, which receive millions of plays per month. We're not saying it is 100% bug free, but we use it for our client work every day, so issues get resolved fast and we stay on-top of the changing browser landscape.

Road Map

Beyond version 2.0 here are some of the features planned for the future:

Version 2.1 ("Shienar")

• Enhance the State Management, so you can perform non-destructive State swaps and persistence.
• A more advanced Particle system, one that can render to a single canvas (rather than spawn hundreds of Sprites), more advanced effects, etc.
• Ability to control DOM elements from the core game and layer them into the game.
• Touch Gestures.
• Support for parallel asset loading.

Version 2.2 ("Tarabon")

• Comprehensive testing across Firefox OS devices, CocoonJS and Ejecta.
• Integration with third party services like Google Play Game Services and Amazon JS SDK.
• Flash CC HTML5 export integration.
• Massively enhance the audio side of Phaser. Take more advantage of Web Audio: echo effects, positional sound, etc.

Beyond version 2.2

• Test out packaging with Node-webkit.
• Game parameters stored in Google Docs.
• Look at HiDPI Canvas settings.
• Multiple Camera support.
• DragonBones support.
• Cache to localStorage using If-Modified-Since. See github request
• Allow for complex assets like Bitmap Fonts to be stored within a texture atlas.
• Look at XDomainRequest for IE9 CORs issues.

Nadion

Nadion is a set of powerful enhancements for Phaser that makes level building even easier. It includes features such as Trigger, Area, Alarms and Emitters, debug panels, state machines, parallax layer scrolling, 'developer mode' short-cuts and more.
