Phaser is a fast, free, and fun open source HTML5 game framework that offers WebGL and Canvas rendering across desktop and mobile web browsers. Games can be compiled to iOS, Android and native apps by using 3rd party tools. You can use JavaScript or TypeScript for development.
Phaser is available in two versions: Phaser 3 and [Phaser CE - The Community Edition](https://github.com/photonstorm/phaser-ce). Phaser CE is a community-lead continuation of the Phaser 2 codebase and is hosted on a separate repo. Phaser 3 is the next generation of Phaser.
Along with the fantastic open source community, Phaser is actively developed and maintained by [Photon Storm](http://www.photonstorm.com). As a result of rapid support, and a developer friendly API, Phaser is currently one of the [most starred](https://github.com/collections/javascript-game-engines) game frameworks on GitHub.
Thousands of developers from indie and multi-national digital agencies, and universities worldwide use Phaser. You can take a look at their incredible [games](https://phaser.io/games/).
**Updated:** I'm pleased to report that development continues at a rapid pace. We're slashing through issues and feature requests as quickly as possible, as well as improving the JSDocs across the entire API. 3.3.0 was released today and we'll launch directly into the next version. Check out the [Change Log](#changelog) for more details.
After 1.5 years in the making, tens of thousands of lines of code, hundreds of examples and countless hours of relentless work: Phaser 3 is finally out. It has been a real labor of love and then some!
Please understand this is a bleeding-edge and brand new release. There are features we've had to leave out, areas of the documentation that need completing and so many cool new things we wanted to add. But we had to draw a line in the sand somewhere and 3.0.0 represents that.
For us this is just the start of a new chapter in Phaser's life. We will be jumping on bug reports as quickly as we can and releasing new versions rapidly. We've structured v3 in such a way that we can push out point releases as fast as needed.
We publish our [Developer Logs](https://phaser.io/phaser3/devlog) in the weekly [Phaser World](https://phaser.io/community/newsletter) newsletter. Subscribe to stay in touch and get all the latest news from us and the wider Phaser community.
You can also follow Phaser on [Twitter](https://twitter.com/phaser_) and chat with fellow Phaser devs in our [Slack](https://phaser.io/community/slack) and [Discord](https://phaser.io/community/discord) channels.
Phaser 3 wouldn't have been possible without the fantastic support of the community and Patreon. Thank you to everyone who supports our work, who shares our belief in the future of HTML5 gaming, and Phaser's role in that.
Developing Phaser takes a lot of time, effort and money. There are monthly running costs as well as countless hours of development time, community support, and assistance resolving issues.
Every week we publish the [Phaser World](https://phaser.io/community/newsletter) newsletter. It's packed full of the latest Phaser games, tutorials, videos, meet-ups, talks, and more. The newsletter also contains our weekly Development Progress updates which let you know about the new features we're working on.
1. Go to https://photonstorm.github.io/phaser3-docs/index.html to read the docs online.
2. Checkout the [phaser3-docs](https://github.com/photonstorm/phaser3-docs) repository and then read the documentation by pointing your browser to the local `docs/` folder.
The documentation for Phaser 3 is an on-going project. Please help us by searching the Phaser code for any instance of the string `[description]` and then replacing it with some documentation.
### TypeScript Definitions
[TypeScript Definitions](https://github.com/photonstorm/phaser3-docs/tree/master/typescript) are now available.
They are automatically generated from the jsdoc comments in the Phaser source code. If you wish to help refine them then you must edit the Phaser jsdoc blocks directly. You can find more details, including the source to the conversion tool we wrote in the Docs repo.
During our development of Phaser 3, we created hundreds of examples with the full source code and assets. Until these examples are fully integrated into the Phaser website, you can browse them on [Phaser 3 Labs](http://labs.phaser.io), or clone the [examples repo][examples]. Note: Not all examples work, sorry! We're tidying them up as fast as we can.
This is a standard empty webpage. You'll notice there's a script tag that is pulling in a build of Phaser 3, but otherwise this webpage doesn't do anything yet. Now let's set-up the game config. Paste the following between the `<script></script>` tags:
`config` is a pretty standard Phaser 3 Game Configuration object. We tell `config` to use the WebGL renderer if it can, set the canvas to a size of 800x600 pixels, enable Arcade Physics, and finally call the `preload` and `create` functions. `preload` and `create` have not been implemented yet, so if you run this JavaScript code, you will have an error. Add the following after `config`:
`game` is a Phaser Game instance that uses our configuration object `config`. We also add function definitions for `preload` and `create`. The `preload` function helps you easily load assets into your game. In `preload`, we set the Base URL to be the Phaser server and load 3 PNG files.
Here we add a sky image into the game and create a Particle Emitter. The `scale` value means that the particles will initially be large and will shrink to nothing as their lifespan progresses.
After creating the `emitter`, we add a logo image called `logo`. Since `logo` is a Physics Image, `logo` is given a physics body by default. We set some properties for `logo`: velocity, bounce (or restitution), and collision with the world bounds. These properties will make our logo bounce around the screen. Finally, we tell the particle emitter to follow the logo - so as the logo moves, the particles will flow from it.
This is a tiny example, and there are hundreds more for you to explore, but hopefully it shows how expressive and quick Phaser is to use. With just a few easily readable lines of code, we've got something pretty impressive up on screen!
There are both plain and minified compiled versions of Phaser in the `dist` folder of the repository. The plain version is for use during development, and the minified version is for production use. You can also create your own builds.
Phaser 3 must be built using Webpack. We take advantage of a number of Webpack features and plugins which allow us to properly tailor the build process. You can elect exactly which features are bundled into your version of Phaser. We will release a tutorial covering the process shortly, but for now please look at our webpack config files to get an idea of the required settings.
You can then run `webpack` to create a development build in the `build` folder which includes source maps for local testing. You can also run `npm run dist` to create a minified packaged build in the `dist` folder.
A special mention must go to @orblazer for their outstanding assistance in helping to complete the JSDoc data-types, callbacks and type defs across the API.
### New Features
* TextStyle has two new properties: `baselineX` and `baselineY` which allow you to customize the 'magic' value used in calculating the text metrics.
* Game.Config.preserveDrawingBuffer is now passed to the WebGL Renderer (default `false`).

* Game.Config.premultipliedAlpha is now passed to the WebGL Renderer as the premultipliedAlpha context property (default `true`).
* You can now specify all of the renderer config options within a `render` object in the config. If no `render` object is found, it will scan the config object directly for the properties.
* Group.create has a new optional argument: `active` which will set the active state of the child being created (thanks @samme)
* Group.create has a new optional argument: `active` which will set the active state of the child being created (thanks @samme)

* TileSprite has a new method: `setTilePosition` which allows you to set the tile position in a chained called (thanks @samme)
* Added the new Action - WrapInRectangle. This will wrap each items coordinates within a rectangles area (thanks @samme)
* Arcade Physics has the new methods `wrap`, `wrapArray` and `wrapObject` which allow you to wrap physics bodies around the world bounds (thanks @samme)
* The Tweens Timeline has a new method: `makeActive` which delegates control to the Tween Manager (thanks @allanbreyes)
* Actions.GetLast will return the last element in the items array matching the conditions.
* Actions.PropertyValueInc is a new action that will increment any property of an array of objects by the given amount, using an optional step value, index and iteration direction. Most Actions have been updated to use this internally.
* Actions.PropertyValueSet is a new action that will set any property of an array of objects to the given value, using an optional step value, index and iteration direction. Most Actions have been updated to use this internally.
* Camera.shake now has an optional `callback` argument that is invoked when the effect completes (thanks @pixelscripter)
* Camera.fade now has an optional `callback` argument that is invoked when the effect completes (thanks @pixelscripter)
* Camera.flash now has an optional `callback` argument that is invoked when the effect completes (thanks @pixelscripter)
* Camera.fadeIn is a new method that will fade the camera in from a given color (black by default) and then optionally invoke a callback. This is the same as using Camera.flash but with an easier to grok method name. Fix #3412 (thanks @Jerenaux)
* Camera.fadeOut is a new method that will fade the camera out to a given color (black by default) and then optionally invoke a callback. This is the same as using Camera.fade but with an easier to grok method name. Fix #3412 (thanks @Jerenaux)
* Groups will now listen for a `destroy` event from any Game Object added to them, and if received will automatically remove that GameObject from the Group. Fix #3418 (thanks @hadikcz)
* MatterGameObject is a new function, available via the Matter Factory in `this.matter.add.gameObject`, that will inject a Matter JS Body into any Game Object, such as a Text or TileSprite object.
* Matter.SetBody and SetExistingBody will now set the origin of the Game Object to be the Matter JS sprite.xOffset and yOffset values, which will auto-center the Game Object to the origin of the body, regardless of shape.
* SoundManager.setRate is a chainable method to allow you to set the global playback rate of all sounds in the SoundManager.
* SoundManager.setDetune is a chainable method to allow you to set the global detuning of all sounds in the SoundManager.
* SoundManager.setMute is a chainable method to allow you to set the global mute state of the SoundManager.
* SoundManager.setVolume is a chainable method to allow you to set the global volume of the SoundManager.
* BaseSound.setRate is a chainable method to allow you to set the playback rate of the BaseSound.
* BaseSound.setDetune is a chainable method to allow you to set the detuning value of the BaseSound.
* Fixed the Debug draw of a scaled circle body in Arcade Physics (thanks @pixelpicosean)
* Fixed bug in `DataManager.merge` where it would copy the object reference instead of its value (thanks @rexrainbow)
* The SceneManager no longer copies over the `shutdown` and `destroy` callbacks in createSceneFromObject, as these are not called automatically and should be invoked via the Scene events (thanks @samme)
* The default Gamepad Button threshold has been changed from 0 to 1. Previously the value of 0 was making all gamepad buttons appear as if they were always pressed down (thanks @jmcriat)
* InputManager.hitTest will now factor the game resolution into account, stopping the tests from being offset if resolution didn't equal 1 (thanks @sftsk)
* CameraManager.getCamera now returns the Camera based on its name (thanks @bigbozo)
* Fixed Tile Culling for zoomed Cameras. When a Camera was zoomed the tiles would be aggressively culled as the dimensions didn't factor in the zoom level (thanks @bigbozo)
* When calling ScenePlugin.start any additional data passed to the method would be lost if the scene wasn't in an active running state (thanks @stuff)
* When calling Timeline.resetTweens, while the tweens are pending removal or completed, it would throw a TypeError about the undefined `makeActive` (thanks @allanbreyes)
* The WebGL Context would set `antialias` to `undefined` as it wasn't set in the Game Config. Fix #3386 (thanks @samme)
* The TweenManager will now check the state of a tween before playing it. If not in a pending state it will be skipped. This allows you to stop a tween immediately after creating it and not have it play through once anyway. Fix #3405 (thanks @Twilrom)
* The InputPlugin.processOverOutEvents method wasn't correctly working out the total of the number of objects interacted with, which caused input events to be disabled in Scenes further down the scene list if something was being dragged in an upper scene. Fix #3399 (thanks @Jerenaux)
* The InputPlugin.processDragEvents wasn't always returning an integer.
* LoaderPlugin.progress and the corresponding event now factor in both the list size and the inflight size when calculating the percentage complete. Fix #3384 (thanks @vinerz@rblopes@samme)
* Phaser.Utils.Array.Matrix.RotateLeft actually rotated to the right (thanks @Tomas2h)
* Phaser.Utils.Array.Matrix.RotateRight actually rotated to the left (thanks @Tomas2h)
* When deleting a Scene from the SceneManager it would set the key in the scenes has to `undefined`, preventing you from registering a new Scene with the same key. It's now properly removed from the hash(thanks @macbury)
* Graphics.alpha was being ignored in the WebGL renderer and is now applied properly to strokes and fills. Fix #3426 (thanks @Ziao)
* The font is now synced to the context in Text before running a word wrap, this ensures the wrapping result between updating the text and getting the wrapped text is the same. Fix #3389 (thanks @rexrainbow)
* Added the ComputedSize component to the Text Game Object, which allows Text.getBounds, and related methods, to work again instead of returning NaN.
* Group.remove now calls the `removeCallback` and passes it the child that was removed (thanks @orblazer)
* The Text testString has changed from `|MÉqgy` to `|MÉqgy`.
* The WebGLRenderer width and height values are now floored when multiplied by the resolution.
* The WebGL Context now sets `premultipliedAlpha` to `true` by default, this prevents the WebGL context from rendering as plain white under certain versions of macOS Safari.
* The Phaser.Display.Align constants are now exposed on the namespace. Fix #3387 (thanks @samme)
* The Phaser.Loader constants are now exposed on the namespace. Fix #3387 (thanks @samme)
* The Phaser.Physics.Arcade constants are now exposed on the namespace. Fix #3387 (thanks @samme)
* The Phaser.Scene constants are now exposed on the namespace. Fix #3387 (thanks @samme)
* The Phaser.Tweens constants are now exposed on the namespace. Fix #3387 (thanks @samme)

* Triangle.getLineC now returns a Line instead of an untyped object. It also now has an optional argument that allows you to pass a Line in to be populated, rather than creating a new one.
* The GameObject `destroy` event is now emitted at the start of the destroy process, before things like the body or input managers have been removed, so you're able to use the event handler to extract any information you require from the GameObject before it's actually disposed of. Previously, the event was dispatched at the very end of the process.
* Phaser 3 is now built with Webpack v4.1.1 and all related packages have been updated (thanks @orblazer)
* On WebGL the currentScissor is now updated when the renderer `resize` method is called (thanks @jmcriat)
* PathFollower.start has been renamed to `startFollow` to avoid conflicting with the Animation component.
* PathFollower.pause has been renamed to `pauseFollow` to avoid conflicting with the Animation component.
* PathFollower.resume has been renamed to `resumeFollow` to avoid conflicting with the Animation component.
* PathFollower.stop has been renamed to `stopFollow` to avoid conflicting with the Animation component.
* BaseSound.setRate has been renamed to `calculateRate` to avoid confusion over the setting of the sounds rate.
