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.
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/).
After 13 beta releases, over 200 resolved issues, thousands of lines of new code and the culmination of over 6 months incredibly hard work, Phaser 3.50 was finally released in December 2020 and we're continuing with updates in the New Year with the 3.52 point release.
It's not hyperbole or exaggeration when I say that Phaser 3.50 is the single biggest point release ever in the history of Phaser. There are quite literally hundreds of new features to explore, updates to key areas and of course bug fixes. I did actually try counting all the changes, but gave up after I'd reached 900 of them! Thankfully, they are, as always, meticulously detailed in the [Change Log](https://github.com/photonstorm/phaser/blob/master/CHANGELOG-v3.50.md). The changes for 3.50 actually grew so large that I had to split them out from the main Change Log and put them into their own file.
However, don't let this overwhelm you. A massive number of the changes are purely internal and while there are absolutely some API breaking changes in this release (hence the large version number jump), we've kept them as sensible as possible. We already know of lots of devs who have upgraded with minimal, or no, changes to their actual game code. We cannot guarantee that for everyone, of course, but depending on how complex your game is, the chances are good.
There is plenty to be excited about in this version. It pulls together most of the R&D that took place earlier this year for Phaser 4 and delivers it to you in version 3. New features include full support for post-processing effects via the new Post FX Pipeline, multi-texture support for faster WebGL rendering, a brand new Layer Game Object for the ability to group and post process objects without impacting their transforms, new event hooks, a massive overhaul of the Animation system, funky looking new Point Lights, a new Pipeline Manager, new Camera effects, the latest version of the Spine Plugin, an extremely powerful new Mesh Game Object, a brand new Render Texture, huge improvements to Bitmap Text, isometric and hexagonal Tilemap support, a new Pushable Arcade Physics Body type, new Geometry Intersection tests, Light 2D Updates and lots, lots, **lots** more!
As usual, I'd like to send my thanks to the Phaser community for their help in both reporting issues and submitting pull requests to fix them. So, please do spend some time digging through the [Change Log](#changelog). I assure you, it's worth while :)
I'd like to send a massive thank-you to everyone who supports [Phaser on Patreon](https://www.patreon.com/photonstorm), GitHub Sponsors and our corporate backers. Your continued funding allows me to keep working on Phaser full-time and this monster of a new release is the very real result of that. If you've ever considered becoming a backer, now is the perfect time!
If you'd like to stay abreast of developments then I'm now publishing them to the [Phaser Patreon](https://www.patreon.com/photonstorm). Here you can find the latest development reports including the concepts behind Phaser 4.
You can also follow Phaser on [Twitter](https://twitter.com/phaser_) and chat with fellow Phaser devs in our [Discord](https://phaser.io/community/discord).
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.
Because Phaser is an open source project, we cannot charge for it in the same way as traditional retail software. What's more, we don't ever want to. After all, it's built on, and was born from, open web standards. It's part of our manifesto that the core framework will always be free, even if you use it commercially, as many of you do.
Those funds allow Phaser to improve, and when it improves, everyone involved benefits. Your support helps secure a constant cycle of updates, fixes, new features and planning for the future.
We use [Patreon](https://www.patreon.com/photonstorm) to manage the backing and you can [support Phaser](https://www.patreon.com/join/photonstorm?) from $1 per month. The amount you pledge is entirely up to you and can be changed as often as you like. Patreon renews monthly, just like Netflix. You can, of course, cancel at any point. Tears will be shed on this end, but that's not your concern.
Go to https://photonstorm.github.io/phaser3-docs/index.html to read the docs online. Use the drop-down menus at the top to navigate the namespaces, classes and Game Objects lists.
Or, if you wish to run the docs locally you can checkout the [phaser3-docs](https://github.com/photonstorm/phaser3-docs) repository and then read the documentation by pointing your browser to the `docs/` folder.
The [TypeScript definitions](https://github.com/photonstorm/phaser/tree/master/types) can be found inside the `types` folder. They are also referenced in the types entry in `package.json`.
Depending on your project, you may need to add the following to your `tsconfig.json` file:
We recently published a new [Phaser 3 TypeScript Project Template](https://github.com/photonstorm/phaser3-typescript-project-template), which you can use to get started with if you like.
The TS defs are automatically generated from the JSDoc comments found in the Phaser source code. If you wish to help refine them then you must edit the Phaser JSDoc blocks directly, not the defs file. You can find more details about the parser we built in the `scripts/tsgen` folder.
We use Webpack to build Phaser and we take advantage of its conditional build flag feature to handle 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. Recent changes to our build steps mean you should now be able to use any other packager, like Parcel, without any config changes.
* The [Complete Phaser 3 Game Development course](https://academy.zenva.com/product/html5-game-phaser-mini-degree/?a=13) contains over 15 hours of videos covering all kinds of important topics.
* Plus, there are [over 700 Phaser tutorials](http://phaser.io/learn) listed on the official website.
During our development of Phaser 3, we created hundreds of examples with the full source code and assets ready available. These examples are now fully integrated into the [Phaser website](https://phaser.io/examples). You can also browse them on [Phaser 3 Labs](https://labs.phaser.io) via a more advanced interface, or clone the [examples repo][examples]. We are constantly adding to and refining these examples.
Super community member RexRainbow has been publishing Phaser 3 content for years, building up an impressive catalogue in that time. You'll find [loads of plugins](https://rexrainbow.github.io/phaser3-rex-notes/docs/site/index.html#list-of-my-plugins), from UI controls such as text input boxes, to Firebase support, Finite State Machines and lots more. As well as the plugins there is also a comprehensive set of 'Notes' about Phaser 3, going into great detail about how the various systems work. It's an invaluable resource and well worth checking out at [https://rexrainbow.github.io](https://rexrainbow.github.io/phaser3-rex-notes/docs/site/index.html)
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!
Ourcade have published [two great Phaser 3 books](https://blog.ourcade.co). They'll take you from getting set-up, through to finishing your first game using modern JavaScript or TypeScript and they're both completely free! They also publish a huge range of quality tutorials and videos, so be sure to check out their site every week.

Learn the secrets of HTML5 game development with Phaser 3.50 while building a cross platform endless runner game. Designed both for beginners and skilled programmers, the course guides you from an empty folder introducing the bare bones of JavaScript to advanced Phaser 3 features. Find out more details about [HTML5 Cross Platform Game Development with Phaser](https://gumroad.com/a/244184179).
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 and should also create your own builds.
Phaser 3 is built using Webpack and we take advantage of the Webpack definePlugin feature to allow for conditional building of the Canvas and WebGL renderers and extra plugins. You can custom the build process to only include the features you require. Doing so can cut the main build file size down to just 70KB.
Read our [comprehensive guide](https://github.com/photonstorm/phaser3-custom-build#creating-custom-phaser-3-builds) on creating Custom Builds of Phaser 3 for full details.
If you wish to build Phaser 3 from source, ensure you have the required packages by cloning the repository and then running `npm install` on your source directory.
You can then run `webpack` to create a development build in the `build` folder which includes source maps for local testing. You can also `npm run dist` to create a minified packaged build in the `dist` folder. For a list of all commands available use `npm run help`.
Traditionally we have always included the most recent Change Log in this README. It was a nice quick way for visitors to scan what's new in the latest version. However, with the 3.50.0 release we cannot do that because the Change Log itself is 1300 lines long and over 160KB in size.
This is somewhat unprecedented for Phaser, but then 3.50 _is_ a truly massive release!
We've organized the Change Log into commonly themed sections to make it more digestible, but we appreciate there is a lot in there. Please don't feel overwhelmed! If you need clarification about something, join us on the Phaser Discord and feel free to ask.
For versions prior to 3.50 you can read the previous [Change Log](https://github.com/photonstorm/phaser/blob/master/CHANGELOG.md) as well.
- Found a bug? Report it on [GitHub Issues][issues] and include a code sample. Please state which version of Phaser you are using! This is vitally important.
