Have you guys try Rubygame? It have good documentation. I think is a fork of
ruby-SDL but I don't know.


Here is one of the "polling" code(I don't know much game development
terminology) that I used for keyboard stuff. Notes that this is a code
snippet from one of my game.

q = Rubygame::EventQueue.new
        while (1)
            if @pet.data['status'] == false
                @screen.background_cleanup(800,600)
                Death.new(@screen)
                @pet.save()
                return
            end
            execute()
            q.each do |event|
                case event
                when Rubygame::KeyDownEvent
                    case event.key
                    when Rubygame::K_S
                        @pet.save()
                    when Rubygame::K_ESCAPE
                        @pet.save()
                        return
                    end
                when Rubygame::MouseDownEvent
                    case event.button
                    when Rubygame::MOUSE_LEFT
                        if @itemmenu.act == true
                            @itemmenu.test(event)
                        else
                            if @item.check(@screen.background,event,@
pet.sprite.return) == true
                                @display.itnext.count()
                            end
                            @display.draw()
                            @screen.screen_clear()
                        end
                    end
                when Rubygame::QuitEvent
                    @pet.save()
                    exit
                when Rubygame::MouseMotionEvent
                    @map.points = event.pos()
                end
            end
        end
