Ruby/SDL on OSX, part 2

[Ilmari Heikkinen]

Was surfing the internets today, in search for workable SDL solutions
for OSX.

And here's two:

This one's a wrapper for executing Ruby. It links the SDL libraries and
ruby and
makes an executable - rsdl, which can then be used to run Ruby/SDL
scripts on
OSX. This works very well, but since it uses a custom executable, you'd
pretty
much need to bundle the exe with your app.

The second way is to use Ruby/Cocoa, which lets you create an SDL
window on OSX.
It spews out a metric ton of error messages but seems to work, sans
input events :I
Wonder if there's any way to make it work better.

# Ruby/Cocoa + Ruby/SDL + OpenGL
# hello_sdl.rb
#
def osx?
PLATFORM =~ /darwin/
end
require 'osx/cocoa' if osx?
require 'sdl'
require 'opengl'
require 'glut'

if $0 == __FILE__ then
app = OSX::NSApplication.sharedApplication() if osx?

SDL.init SDL::INIT_VIDEO
SDL.setGLAttr SDL::GL_DOUBLEBUFFER, 1
SDL.setVideoMode 640, 480, 32, SDL::OPENGL
SDL::WM.setCaption "Hello SDL & OpenGL", ""

GL.ClearColor(0,0,0,0)
GL.Enable(GL:EPTH_TEST)
GL.Clear(GL::COLOR_BUFFER_BIT | GL:EPTH_BUFFER_BIT)
GL.MatrixMode(GL:ROJECTION)
GL.Enable(GL::LIGHTING)
GL.Enable(GL::LIGHT0)
GL.Light(GL::LIGHT0, GL:OSITION, [2,3,4,1])
GL.LoadIdentity()
GLU.Perspective 60, 1.3, 0.1, 100
GL.MatrixMode(GL::MODELVIEW)
GL.LoadIdentity()
GLU.LookAt(2,2,2 , 0,0,0, 0,1,0)
GLUT.SolidCube(1)
SDL.GLSwapBuffers()

loop{
e = SDL::Event2.poll
case e
when SDL::Event2::KeyUp
break if e.sym == ?q or e.sym == 27
when SDL::Event2::Quit
break
end
}
end
