Ok im going to create a series of tuts on how to create a Very simple game in Ruby.

Firstly, you'll need the Gosu Lib. found HERE!

after you have that done. Create a folder for the project. then extract the Gosu folder (somewhere thats not in the project folder) then go into the Lib folder of gosu. copy "gosu.for_1_8.so", "gosu.rb" and "fmod.dll" into your project folder.

now. open up Notepad(or a texteditor of your choice) and put this code in:

CODE

require 'gosu'

class GameWindow < Gosu::Window
  def initialize
    super(640, 480, false)
    self.caption = "Gosu Window"
  end

  def update
  end

  def draw
  end
end

window = GameWindow.new
window.show

now save it as main.rb and run.

now i shall explain what all this does.

CODE

require 'gosu'

this allows the ruby file to use Gosu's built in classes.

CODE

class GameWindow < Gosu::Window

creates a new class defined by the Gosu::Window class, allowing you to create a window.

CODE

def initialize
    super(640, 480, false)
    self.caption = "Gosu Window"
  end

when the GameWindow is created, it sets up a new window of 640 width and 480 hight, with a caption of Gosu Window.

CODE

window = GameWindow.new
window.show

creates a new instance of the GameWindow class, then displays it on the screen.

if there are any problems feel free to ask.

the next part of this tut will show you how to create a sprite on the screen and move it using the arrow keys .. keep a look out
