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:** We've just released Phaser 3.6.0. This release introduces the full version of Containers, updates more documentation and carries on the update and bug fixing work. It comes shortly after the 3.5 and 3.4 releases which unified the Camera Effects and introduced powerful new Scene Transitions. We appreciate that our current release velocity is extremely high, often with several versions per week, so as always, please check out the [Change Log](#changelog) for comprehensive details about what recent versions contain.
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.
We use Webpack to build Phaser and we take advantage of several features specific to Webpack to do this, including `raw-loader` to handle our shader files and build-time flags for renderer swapping.
If you wish to use Webpack with Phaser then please use our [Phaser 3 Project Template](https://github.com/photonstorm/phaser3-project-template) as it's already set-up to handle the build conditions Phaser needs.
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](https://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.
* Containers are now fully available! We have removed the beta warning and fixed the way in which they work with Cameras, input and scroll factors. They are also fully documented, so please see their docs and examples for use.
* Group.getLast will return the last member in the Group matching the search criteria.
* Group.getFirstNth will return the nth member in the Group, scanning from top to bottom, that matches the search criteria.
* Group.getLastNth will return the nth member in the Group, scanning in reverse, that matches the search criteria.
* Group.remove has a new optional argument `destroyChild` that will call `destroy` on the child after removing it.
* Group.clear has a new optional argument `destroyChild` that will call `destroy` on all children in the Group after removing them.
* Impact Physics Game Objects have changed `setLite` to `setLiteCollision`.
* Impact Physics Game Objects have changed `setPassive` to `setPassiveCollision`.
* Impact Physics Game Objects have changed `setFixed` to `setFixedCollision`.
* Impact Physics Game Objects have changed `setActive` to `setActiveCollision`, previously the `setActive` collision method was overwriting the Game Objects `setActive` method, hence the renaming.
* The modifications made to the RTree class in Phaser 3.4.0 to avoid CSP policy violations caused a significant performance hit once a substantial number of bodies were involved. We have recoded how the class deals with its accessor formats and returned to 3.3 level performance while still maintaining CSP policy adherence. Fix #3594 (thanks @16patsle)
* The Retro Font namespace has changed to `Phaser.GameObjects.RetroFont`. Previously, you would access the parser and constants via `BitmapText`, i.e.: `Phaser.GameObjects.BitmapText.ParseRetroFont.TEXT_SET6`. This has now changed to its own namespace, so the same line would be: `Phaser.GameObjects.RetroFont.TEXT_SET6`. The Parser is available via `Phaser.GameObjects.RetroFont.Parse`. This keeps things cleaner and also unbinds RetroFont from BitmapText, allowing you to cleanly exclude it from your build should you wish. All examples have been updated to reflect this.
* If using the `removeFromScene` option in Group.remove or Group.clear it will remove the child/ren from the Scene to which they belong, not the Scene the Group belongs to.
* Fixed a bug that caused data to not be passed to another Scene if you used a transition to start it. Fix #3586 (thanks @willywu)
* Group.getHandler would return any member of the Group, regardless of the state, causing pools to remain fixed at once member. Fix #3592 (thanks @samme)
