Phaser is a fast, free, and fun open source HTML5 game framework that offers WebGL and Canvas rendering across desktop and mobile web browsers and has been actively developed for over 10 years.
Games can be built for the web, or as YouTube Playables, Discord Activities, Twitch Overlays or compiled to iOS, Android, Steam and native apps using 3rd party tools. You can use JavaScript or TypeScript for development. Phaser supports over 40 different front-end frameworks including React and Vue.
Phaser is commercially developed and maintained by **Phaser Studio Inc** along with our fantastic open source community. 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.
You are looking at the Beta Release of Phaser v4. There are large internal differences between Phaser v3 and v4, although the public API has remained largely, but not entirely, the same.
Phaser v4 contains Phaser Beam, our brand-new and highly efficient WebGL renderer. Virtually the entire renderer from v3 has been replaced and this transition will be documented in its own Change Log.
✔️ We have removed the following polyfills: Array.forEach, Array.isArray, AudioContextMonkeyPatch, console, Math.trunc, performance.now, requestAnimationFrame and Uint32Array.
✔️ We have removed the Facebook Plugin detection constants from the core library.
✔️ We have removed the Camera3D Plugin.
✔️ We have removed the Layer3D Plugin.
* The `Geom.Point` class and all related functions will be removed. All functionality for this can be found in the existing Vector2 math classes. All Geometry classes that currently create and return Point objects will be updated to return Vector2 objects instead.
*`Vector2.ceil` is a new method that will apply Math.ceil to the x and y components of the vector. Use as a replacement for `Geom.Point.Ceil`.
*`Vector2.floor` is a new method that will apply Math.floor to the x and y components of the vector. Use as a replacement for `Geom.Point.Floor`.
*`Vector2.invert` is a new method that will swap the x and y components of the vector. Use as a replacement for `Geom.Point.Invert`.
*`Vector2.projectUnit` is a new method that will calculate the vector projection onto a non-zero target vector. Use as a replacement for `Geom.Point.ProjectUnit`.
*`Math.GetCentroid` is a new function that will get the centroid, or geometric center, of a plane figure from an array of Vector2 like objects. Use as a replacement for `Geom.Point.GetCentroid`.
*`Math.GetVec2Bounds` is a new function that will get the AABB bounds as a Geom.Rectangle from an array of Vector2 objects. Use as a replacement for `Geom.Point.GetRectangleFromPoints`.
Full TypeScript definitions can be found inside the [types folder](https://github.com/phaserjs/phaser/tree/master/types). They are also referenced in the `types` entry in `package.json`, meaning modern editors such as VSCode will detect them automatically.
Phaser wouldn't have been possible without the fantastic support of the community. Thank you to everyone who supports our work, who shares our belief in the future of HTML5 gaming, and Phaser's role in that.
