Newbie needs some advices

Hi, I'm new to scripting and I figured out that AngelScript would be the best solutions for me, as it looks. I have it compiled and included in my project. I know how to start the AngelScript engine, and so on. I'm programming in C++, so with classes and everything (the samples only have non-class code), some of them are singletons, some not, some have static methods, some not, etc. So, I want to extend the coodebase by AngelScript to allow some things to be flexible and easy changable. What I want to do currently is the following: an ingame console. I want to have it behave like this: - User enters "command arg1 arg2 arg3" - if there is a function called "command", check how many and what arguments it need - if user entered correct number and types odf arguments it will be execute with arguments "arg1 arg2 arg3" My problem currently is: how do I evaluate the arguments before passing it to AngelScript? If I add a new command in the .as script file by writing a "void newcommand(int arg1, bool arg2)" function, then my C++ code won't know the types of arg1 and arg2. So, I donT' know what and how often to call the SetArg..() functions. Or if I rephrase this: I don't know how to prepare my C++ code so that I can add new AngelScript functions that can be called from C++ without changing the C++ for each new .as script function. Did I missed or missunderstod some basic concept here? And some general questions: I'D like to see some "real world" code (big projects) using AngelScript. Are there any open source projects? What are good practices (in C++ when working with the API)?

You could register the global instance as a global variable.

Indeed. That's what I usually do:



  r = engine->RegisterGlobalProperty("Singleton single", Singleton::GetInstance()); assert( r >= 0 );
