Phaser - HTML5 Game Framework

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 game frameworks on GitHub.

v4 Beta Release

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.

Please only use this release if you wish to help beta test Phaser v4.

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.

Other changes also include the following:

✔️ We have removed Phaser.Struct.Set and replaced it with a regular JS Set instance. This means methods like iterateLocal are gone.
✔️ We have removed the Create.GenerateTexture function and all of the Create Palettes and the create folder.
✔️ TextureManager.generate has been removed as a result of the GenerateTexture removal.
✔️ We have removed the phaser-ie9.js entry-point.
✔️ We have removed Math.SinCosTableGenerator.
✔️ 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.

• We are removing Phaser.Struct.Map and replacing it with a regular JS Map instance. This means methods like contains and setAll will be gone.
• The Spine 3 and Spine 4 plugins will no longer be updated. You should now use the official Phaser Spine plugin created by Esoteric Software.

Point.Ceil = Vector2.ceil Point.Floor = Vector2.floor Point.Clone = Vector2.clone Point.CopyFrom(src,dest) = dest.copy(src) Point.Equals = Vector2.equals Point.GetCentroid = Math.GetCentroid Point.GetMagnitude = Vector2.length Point.GetMagnitudeSq = Vector2.lengthSq Point.Invert = Vector2.invert Point.Negative = Vector2.negate Point.SetMagnitude = Vector2.setLength Point.Project = Vector2.project Point.ProjectUnit = Vector2.projectUnit Point.Interpolate = Math.LinearXY Point.GetRectangleFromPoints = Math.GetVec2Bounds

• 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.
• Math.TAU is now actually the value of tau! (i.e. PI * 2) instead of being PI / 2.
• Math.PI2 has been removed. You can use Math.TAU instead. All internal use of PI2 has been replaced with TAU.
• Math.PI_OVER_2 is a new constant for PI / 2 and all internal use of TAU has been updated to this new constant.
• Geom.Circle.getPoint, getPoints and getRandomPoint now all return Vector2 objects instead of Point.
• The functions Geom.Circle.CircumferencePoint, Circle.CircumferencePoint, Circle.GetPoint, Circle.GetPoints, Circle.OffsetPoint and Circle.Random all now take and in some cases return Vector2 instances instead of Point objects.
• Geom.Ellipse.getPoint, getPoints and getRandomPoint now all return Vector2 objects instead of Point.
• The functions Geom.Ellipse.CircumferencePoint, Ellipse.CircumferencePoint, Ellipse.GetPoint, Ellipse.GetPoints, Ellipse.OffsetPoint and Ellipse.Random all now take and in some cases return Vector2 instances instead of Point objects.
• Geom.Line.getPoint, getPoints and getRandomPoint now all return Vector2 objects instead of Point.
• The functions Geom.Line.GetEasedPoint, Line.GetMidPoint, Line.GetNearestPoint, Line.GetNormal, Line.GetPoint, Line.GetPoints, Line.Random and Line.RotateAroundPoint all now take and in some cases return Vector2 instances instead of Point objects.
• The Geom.Polygon.getPoints method now returns Vector2 objects instead of Point.
• The functions Geom.Polygon.ContainsPoint and Polygon.GetPoints all now take and in some cases return Vector2 instances instead of Point objects.
• Geom.Rectangle.getPoint, getPoints and getRandomPoint now all return Vector2 objects instead of Point.
• The functions Geom.Rectangle.ContainsPoint, Rectangle.GetCenter, Rectangle.GetPoint, Rectangle.GetPoints, Rectangle.GetSize, Rectangle.MarchingAnts, Rectangle.MergePoints, Rectangle.OffsetPoint, Rectangle.PerimeterPoint, Rectangle.Random and Rectangle.RandomOutside all now take and in some cases return Vector2 instances instead of Point objects.
• Geom.Triangle.getPoint, getPoints and getRandomPoint now all return Vector2 objects instead of Point.
• The functions Geom.Triangle.Centroid, Triangle.CircumCenter, Triangle.ContainsArray, Triangle.ContainsPoint, Triangle.GetPoint, Triangle.GetPoints, Triangle.InCenter, Triangle.Random and Triangle.RotateAroundPoint all now take and in some cases return Vector2 instances instead of Point objects.

v4.0.0 Beta 2 Updates:

• Better roundPixels handling via bias.
• UUIDs for DynamicTexture names.
  • Masks work (again). Big feature!
• DynamicTexture can resize immediately after creation.
• Fix shader compilation issues on diverse systems. * Shapes/Graphics should work again in Firefox. * Issues with inTexDatum should be eliminated in affected Linux systems.
• Fix Extern and extend its rendering potential (see Beam Examples).
• TileSprite now assigns default dimensions to each dimension separately.
• BaseFilterShader now accesses loaded shader cache keys correctly.

Installing Phaser from NPM

Install via npm:

npm install phaser@beta

Phaser TypeScript Definitions

Full TypeScript definitions can be found inside the types folder. They are also referenced in the types entry in package.json, meaning modern editors such as VSCode will detect them automatically.

Depending on your project, you may need to add the following to your tsconfig.json file:

"lib": ["es6", "dom", "dom.iterable", "scripthost"],
"typeRoots": ["./node_modules/phaser/types"],
"types": ["Phaser"]

Have fun!

Grab the source and join the fun!

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.

Happy coding everyone!

Cheers,

Rich and the whole team at Phaser Studio
