Hi
I'm tiring to run a whole XNA game from IronRuby but I'm having some
trouble translating the code from c# to ruby. That might be because
I'm
really new at Ruby.
here is what I wrote so far
Game = Microsoft::Xna::Framework::Game
GraphicsDeviceManager =
Microsoft::Xna::Framework::GraphicsDeviceManager
Graphics=Microsoft::Xna::Framework::Graphics
You can avoid all this by writing
include Microsoft::Xna::Framework
it's more-or-less the equivalent of using namespace
class Game1 < Game
def Game1
graphics = GraphicsDeviceManager.new this
end
Ruby uses 'self' instead of 'this', and constructors are always def
initialize, not def ClassName
def Initialize
super
#is this ok?
#in C# i have base.Initialize()
end
Yep super should be fine
#is this ok?
#in C# i have protected override void Draw(GameTime gameTime)
def Draw
In ruby you should have def draw(game_time)
Game::GraphicsDevice.Clear Graphics::Color.CornflowerBlue #i don't
think
this is is how to access the colour struct
Not sure off the top of my head but I think it should be
Color::CornflowerBlue
super gameTime
That should be fine. Normally in ruby you don't need to pass arguments
to calls to super, but I'm not sure how IronRuby handles this when
interopping with the CLR...
#is this ok?
#in C# i have base.Draw(gameTime)
end
end
game = Game1.new
game.run
Last 2 lines look fine :-)
I'd really suggest you stop and step back a bit, and learn some of the
basics of the ruby programming language.
Also note that C# uses UpperCamelCase for everything, whereas ruby
uses lower_snake_case for everything (except class names)
IronRuby will translate these for you, so if you have a C# method
called MoveAllZig(), then ruby code to call that will be move_all_zig
Good luck!
