Re: [GD-General] Off the shelf scripting languages

[Nalin S. <ns...@vs...>]

Incase you're programming on Win32 platform; one way to quickly solve your
problem is to expose all the scriptable objects as com objects that expose
the IDispatch interface (easily done through Wizards in VC++ or VS.NET); and
then use either JavaScript or VBScript as the scripting language each of
whose interpreters come build into Windows; or get installed with MSIE onto
Win98/95.

This way you can have a scriptable game-engine up and running in a matter of
2-3 max 6-7 days with an industry strength scripting language.

Also, in the past I've written things that allow Microsoft Java VM to
interpret java byte-code that manipulates COM objects or even calls
functions from DLLs; and this is much simpler than it sounds on first glance
and you can in essence do the same for C# also incase you want to use C# as
the scripting language. By simple I mean one can write an ISAPI Java servlet
container that invokes java servlets in the Microsoft JVM in less than 800
lines of code; which would allow you to run java servlets using IIS or PWS
on WinNT 4.

Alternatively; if you're open to exposing your scriptable objects as COM
objects; you can even write a VB DLL that uses those objects that'd get
loaded by your game engine at run-time; with the speed, flexibility and
processing power of VB.
