Subject: [ruby-talk:23204] C++ Access to script

Hi there ! 

Making progress on my game engine and starting to implement
persistence and editor features, i need a way to store / edit script
information.

I embeded the RUBY interpreter into my C++ Game engine, exporting some
game classes so that they can be used in the script code. Game Objects
are derived from exported C++ classes in ruby... Now i want to know in
the C++ Side of the engine which classes exist in the Ruby Script
which are derived from a special Ruby Class name .... To complicated ?

ok c++:

class Object 
{
};

SCRIPT_EXPORT( Object as GObject)

ruby: 

class SpaceShip < Rs::GObject 
  def initialize()
  end

end

s1 = SpaceShip.new()
s2 = SpaceShip.new()

now in C++ I want to have somthing like this


QueryScriptObjectClasses( vector<String> & names )
which should then contain "SpaceShip"

Then I would need a method that returns the variable names of all
SpaceShip classes

QueryScriptObjectInstances( vector<String>& vars,"SpaceShip")
which should then store in the vars "s1" and "s2" 


Is that possible from the C++ side ? That would be great ....

Ok the next thing after that i have a give instance name retrieved
from QueryScriptObjectInstances i would need to enumerate the
methods,parameters, and variables this class instance has also from
the C++ side ......

GetObjectMethods( "s1",vector<String> methods )
GetObjectVariables( "s1",vector<String> variables,vector<String> types
);


With that i could serialize all script objects automatically, send
them over the network ,and create a great script editor...

HOpe anyone can help
