motion-game

Gem Version

motion-game is a cross-platform mobile game engine for RubyMotion. It lets you write mobile games in Ruby for iOS, tvOS and Android.

motion-game is currently in beta. Please give it a try and report problems you find to us.

Features

  • Use Ruby :-) motion-game exposes a pure Ruby API to write games for mobile devices. You can write a video game all in Ruby.
  • 100% cross-platform: motion-game projects are fully cross-platform for iOS, tvOS and Android. One codebase runs everywhere.
  • Fully-featured: motion-game has audio, sprites, animations, particles, device sensors / events, scene graph / director, UI widgets, etc.
  • Solid foundations: the motion-game API is implemented using popular and stable opensource libraries, such as cocos2d-x, box2d, and more. motion-game projects are also based on RubyMotion which offers portable Ruby runtimes for iOS and Android as well as static compilation of Ruby code.
  • Native compilation: your Ruby code will be compiled into optimized native code for each platform you target. There is no interpreter and the original Ruby code will not be in the app.
  • Platform APIs access: if you need it, you can call the entire set of public iOS, tvOS or Android APIs from Ruby code as well.

Getting Started

Installing RubyMotion

RubyMotion 4.7+ is required. A starter version can be downloaded for free. You also need to set up your computer for mobile development (iOS and/or tvOS and/or Android). Follow the Getting Started guides after installation.

Installing motion-game

Binaries

motion-game is available as a gem:

$ gem install motion-game

Source

You can build your own copy of motion-game:

  • Make sure you have your system set up for Android develpment: motion android-setup --api_version=16.
$ git clone https://github.com/HipByte/motion-game.git && cd motion-game
$ git submodule update --init
$ bundle
$ rake build:setup

$ rake gem
$ gem install motion-game-x.x.gem

Developing Locally

Once you have the source locally. Create a motion-game project as a sibling to the motion-game directory using the motion create --template=motion-game PROJECTNAME command.

Update the reference to motion-game in your Gemfile to point to your local instance of motion-game:

gem 'motion-game', path: '../motion-game'

Chances are all of you changes will be done in the /src directory (since it'll probably be adding missing Cocos2dx methods).

Once you've made your change in the correct .cpp file, run rake build:ios/rake build:android to test your changes locally (running rake gem is a longer process which you don't have to do).

Here are some examples of how to add missing apis to motion-game:

Hello World

$ motion create --template=motion-game HelloWorld
$ cd HelloWorld

iOS

$ rake ios:simulator
$ rake ios:device

tvOS

$ rake tvos:simulator
$ rake tvos:device

Android

$ rake android:emulator
$ rake android:device

API reference

The whole framework API is documented. The API reference is available online.

You can also build the API reference locally:

$ rake doc
$ open doc/index.html

Samples

The samples directory contains sample projects.
