Clone cocos2dx-mruby and generate stub files.

tkrmb2:~/proj% git clone git@github.com:takeru/cocos2dx-mruby.git

tkrmb2:~/proj% cd cocos2dx-mruby

tkrmb2:~/proj/cocos2dx-mruby% rm generated/*

MrubyCocosDenshion.cpp  MrubyCocosDenshion.h

Add *.cpp/h files into Classes.

Edit AppDelegate.cpp

#include "CCMrubyEngine.h"

  CCMrubyEngine* pEngine = CCMrubyEngine::defaultEngine();
  CCScriptEngineManager::sharedManager()->setScriptEngine(pEngine);

  std::string path = CCFileUtils::sharedFileUtils()->fullPathForFilename("hello.rb");
  pEngine->executeScriptFile(path.c_str());

Put hello.rb into Resources.

# hello.rb
puts 'hello!!'
include Cocos2d
d = CCDirector.sharedDirector
win_size = d.getWinSize
sprite = CCSprite.create("Icon-114.png")
sprite.setPosition(win_size.width/2, win_size.height/2)
scene = CCScene.create
scene.addChild(sprite)
d.runWithScene(scene)

And, click Run button.
