Logan put together a pretty impressive container for Jemini (note the rename for Google-ability) demos. Just pick from a menu to load a state. Showing a description? One line. Offering running updates on a variable’s value? One line.

class AudibleState < Gemini::BaseState

  def create_ui
    text "Click in different places in the window to emit a sound at different pitches and volumes."
    watch('Pitch') { @pitch }
    watch('Volume') { @volume }
  end

  def load
    
    set_manager :sound, create(:SoundManager)

    audible = create :GameObject, :Audible, :ReceivesEvents
    
    audible.load_sound :boom, "boom.wav"
    
    load_keymap :MouseKeymap
    
    audible.handle_event :mouse_pressed do |message|
      @pitch = message.value.pointer.x / 100.0
      @volume = message.value.pointer.y / 100.0
      audible.emit_sound :boom, @volume, @pitch
    end
    
  end
end
