JS Player for Animatron project (v1.3)


Build Status

[Currently all tests are disabled and not time-bombed in refactoring purposes (some will be turned back on after refactoring iterations, some not), so the badge below just provides nice ecologically green color for us to feel safe]

[Documentation in general is a subject to change drastically, because it's outdated now. Be aware!]

Licensed under MIT License, see LICENSE file.

NB: Development is in progress. Some links below may not work at all, some documentation is outdated, API is radically changing just in this very minute, so we will update docs when it comes to a more stable state, sorry!

See for description on current API state (be aware, it may appear not updated to the real current state).

See in action

Navigate to corresponding Animatron site section, there are some useful links:

  • Sandbox to try it for yourself.
  • Demos to see it in action with some demos (they're not so good-looking for the moment).
  • Tests to see what features are working for now.

Run one of the tests/index.html and run any of the tests to see if something is broken in your version of player.


See Embedding section in API docs (or at github) on detailed information about embedding process.

Also, a detailed article about it is located here.

Accessible from Cloud

The player files are accessible from the Amazon S3 Cloud in different bundles, each is just one file, so you may choose what you want to take:

  • Standard Bundle (vendor files + DOM-engine + player only; a lightweight bundle) is located at
  • Animatron Bundle (vendor files + DOM-engine + player + builder + animatron importer + required modules; a bundle for the Animatron tool and embedding Animatron preview) is located at
  • Develop Bundle (vendor files + DOM-engine + player + builder + animatron importer + no modules; a bundle for game or script-based animation developers) is located at
  • Hardcore Develop Bundle (vendor files + DOM-engine + player + builder + animatron importer + all player additional modules, like collisions; a bundle for those game developers who uses complex things like collisions) is located at

Include one of them as a script to your page, and you're done!

Also, all files are accessible separately, if you want:

URLs scheme for all of them is:<version>|/latest)[(/bundle|/vendor|/engine|/import|/module)]/<file>[.min].js
  • (/<version>|/latest) — required; a version of the player you want to get files from (e.g. v0.9), or the latest version
  • [(/engine|/bundle|/vendor|/import|/module)] — optional; bundles are located in /bundle folder, /vendor folder is for external files required for player, /engine for engines (like DOM-engine), is /import is for importers, /module is for modules; /bundle files are supposed to be added before any other files, if you need them separately and they are not included in the bundle themselves. /vendor files should appear before player files (player.js, builder.js, ...); /import and /module files should appear after player files (player.js, builder.js, ...).
  • [.min] — optional; specify if you want to get minimized (and gzipped) version of a file.


  • file contains the list of all versions.
  •<version>|/latest)/BUILD file contains the build number and date when this version was built (only for recent versions).


You may clone to get your own copy of all of the files.

To use JS player in current state, you may download separately or duplicate from the cloned repository and then add these files in specified order:

  • [Optional] src/vendor/json2.js (JSON parser, if target broswer not supports it (currently required only for Animatron Import))
  • src/vendor/matrix.js
  • src/engine/dom-engine.js
  • src/anm.js
  • src/player.js
  • [Optional] src/builder.js (allows to build animations in a functional way)
  • [Optional] src/import/animatron_importer.js (allows to load animations from Animatron tool)
  • [Optional] src/module/collisions.js (if you plan to test collisions / point-contains / intersections with your shapes)
  • [Optional] src/module/*.js (currently other modules are extending player only for usage with Animatron-importer)

And add them in the same order to your page header. Don't forget the LICENSE :).

Run sandbox/sandbox.html to try it for yourself.

Run examples/demo.html to see it in action with some demos (they're not so good-looking for the moment).

Run one of the tests/index.html and run any of the tests to see if something is broken in your version of player.

If you'd want to run them from terminal instead of browser, you'll need to have PhantomJS installation and then start[ spec]


When you build player with jake, it also creates several bundles, they are:

  1. Standard: just player merged with required vendor files — for quick uses of the player (when developer wants very lightweight version)
  2. Animatron: vendor files + player + importer from Animatron — exactly this one will be used in embedded player and in the Animatron tool
  3. Develop: vendor files + player + Builder that simplifies working with scenes in a way like JQuery simplifies working with DOM — it will work ok for developing some general (in terms of code complexity) games.
  4. Hardcore: vendor files + player + Builder + additional modules (like collisions support) — intended to be used to write more complex games


To build locally, you'll only need to have jake intalled. Optionally, if you want to get minified sources, please install uglify-js >= 2 in addition.

Warning: Build system currently uses cat, mv and some other commands from UNIX shell, so it will need some UNIX-friendly environment to build correctly. However, node.js for MS Windows currently provides an integrated console that supports stuff like that, so probably it will work ok even without installing MinGW or Cygwin.

Then, you'll just need to run:

# or, the same
jake dist

And you have all the required files in proper structure inside the ./dist sub-directory. (Actually, it just prepares bundles and copies only the sources used in distribution).

You also may want to run dist-and-min to tell jake to additionally generate and put minified files (what is UglifyJS for) in the very same dist directory, among with prepared source maps:

jake dist-min

The latter task generates all the files which required for distribution. Actually, it should read "dist and min", but dist-n-min looks harder to type.

If you want to generate docco (install it first) docs, run:

jake docs

If you want check if tests are failing in CLI, use (you'll need phantomjs installed for that):

jake test

Or, to check just a specific part of tests (see ./tests/spec/spec-list.js for a list of all specs), use:

jake test[01.player/*]
jake test[02.animations/01.guids]

Here's the contents of the jake -T call, which describes each existing task:

jake default               # Get full distribution in the /dist directory.
                           # Exactly the same as calling {jake dist}.

None of the libraries or software is required to run and use the player, except HTML5-Compatible browser. The versions listed below are for the development participation only.

Versions of software used for development (only node, jake and uglifyjs are required for building):

  • node: 0.8.9
  • npm (node.js): 1.2.8
  • jake (node.js): 0.5.14 (global installation recommended)
  • uglify-js (node.js): 2.2.5 (global installation recommended)
  • phantomjs: 1.7.0 (global installation recommended)
  • jasmine-node: 1.7.1
  • docco (node.js): 0.6.2
  • markdown (Python module): ?
  • orderly (node.js): 1.1.0
  • jsonschema (node.js): 0.3.2
  • aws2js (node.js): 0.8.3 (requires make)
  • walk (node.js): 2.2.1

Requirements for different actions are:

  • Building a distribution: node, jake, uglify-js
  • Testing sources: node, jake, jasmine-node, phantomjs
  • Build HTML documentation: node, jake, docco, python, Python markdown module
  • Validate Animatron scenes: node, jake, orderly, jsonschema
  • Putting Files to S3: node, jake, aws2js, walk
