I'm trying out Gosu, which is a 2D game library written in C++ with Ruby bindings (Wikipedia article).
The Ruby documentation is sparse but sufficient.
The gem is easy to install:
$ gem install gosu
A 'Hello World!' app requires about 20 lines of code:
require 'rubygems' require 'gosu' class HelloWindow < Gosu::Window def initialize super( 250, 100, false ) @background_image = Gosu::Image.new(self, 'hello_world.png') end def draw @background_image.draw(0, 0, 1) end def button_down(id) close end end HelloWindow.new.show
Run it like this:
$ ruby hello_gosu.rb
The program creates the window shown at the start of this article.
The complete code is in a GitHub repository.
