Cocos2d-JS provides a consistent development experience for whichever platform you want to distribute to, both web and native. "Code once, run everywhere" is incredibly easy and natural in Cocos2d-JS. With one single javascript code base, you can run your game on both web browsers and native platform including Mac OS, Windows, iOS, Android. This will bring your game great opportunities in almost all canals of distribution.

Furthermore, javascript friendly API makes your game development experience a breeze, easy to code, test and distribute. Cocos2d-JS also offers Cocos Console, a script tool, to simplify the creation of projects and let you start coding right away. You can use it to create a new project and publish it to android, iOS, Mac OS or web.

##How to Start a New Game

  1. Download the code from Cocos2d download site
  2. Run setup.py
  3. Run the cocos script

Example:

$ cd cocos2d-js
$ ./setup.py
$ source FILE_TO_SAVE_SYSTEM_VARIABLE

$ cocos new MyGame -l js -d /directory/to/project
$ cd /directory/to/project/MyGame

###Run the project under the game directory

  • Run Cocos2d-html5 project with a Websever:

     cocos run -p web

  • Compile and run project in Cocos2d-JSB :

     cocos compile -p ios|mac|android|web
 cocos run -p ios|mac|android|web

You may need to provide your NDK, Android SDK and ANT's path during the setup. Note that this tool is developed with python, so you will need python (32bit) 2.7.5 or later installed on your machine (but it doesn't support Python3). Please refer to Cocos Console document.

And if you have any doubt about the usage, please use -h with any command to have some help messages.

You can also use prebuilt Xcode or Visual Studio project which is located in Game/frameworks/runtime-src/proj.xxx

    • js-bindings : JSB engine source (include Cocos2d-x and JSB)
    • runtime-src : IDE projects (android, ios, mac, win32)
  • publish : Published apps
  • runtime : Debug app files
  • tools : JS Bindings generator
  • res : Your game resource folder for images, sounds, etc
  • src : Your game's js files folder

Documentations

##Github note

If you fork our github repository or download the package from github, you will need to do some extra tasks:

  • Run frameworks/js-bindings/cocos2d-x/download-deps.py to download external dependencies for Cocos2d-x
  • Run tools/cocos2d-console/download-bin.py to download bin files for some cocos2d-console plugins like Google Closure Compiler, JSC Compiler.

Otherwise, you will fail to compile your JSB projects.
