CDN

Phaser is on the jsDelivr CDN. Include one of the following in your html:

<script src="//cdn.jsdelivr.net/npm/phaser@3.20.1/dist/phaser.js"></script>
<script src="//cdn.jsdelivr.net/npm/phaser@3.20.1/dist/phaser.min.js"></script>

Looking for Phaser 2 / CE?

The latest CE release is 2.13.3 released on 17th September 2019.

Which file should I download?

Familiar with git? Use the "clone" link to get the whole repo. The "js" and "min.js" links download pre-built versions of Phaser with all modules enabled. The zip and tar links download an archive of the repository. If you're just doing a quick test then it's safe to grab the js files, however it's always worth having the source code to hand for reference.

What's New in 3.20.1?

Version 3.20.1 - Fitoria - 15th October 2019

Updates

  • The remove-files-webpack-plugin plugin has been moved to a devDependency (thanks @noseglid)

Bug Fixes

  • UpdateList.shutdown wasn't removing the Scene Update event listener, causing actions to be multiplied on Scene restart (such as animation playback). Fix #4799 (thanks @jronn)
  • Container.mask wouldn't render in WebGL due to a change in the way child masks were handled. Container masking now works again as in 3.19. Fix #4803 (thanks @paulsymphony)
  • DynamicTilemapLayer.setCollision would cause an indexOf error when trying to access the layer data. Fix #4800 (thanks @PavelMishin)
  • SceneManager.run (and consequently ScenePlugin.run) was using an out-dated way of checking if a Scene was paused before trying to resume it, causing a Scene to be started again instead of resumed. It now uses the Systems.isPaused function instead. Fix #3931 (thanks @alexeymolchan)
