Way back at the start of this year, I wrote about how I’d been working on a new Object Pascal-based script engine built around Delphi’s extended RTTI system. And then it got real quiet, because more immediate concerns took priority for me. But I’ve gotten to the point in my game engine development where I really need to put in the scripting system, so I spent the last couple weeks finishing up the implementation and tuning the performance a little, and now I’ve got an alpha version ready. If anyone would like to try it out, they can find it on Google Code.

On a more technical level it suffices to say that they use custom and extremely compact and fast data structures, tricks and hacks to be able to represent millions and millions of objects within the constraints of a 32-bit Windows system. Throw in the use of Physical Address Extensions, storing per-class information in “virtual” class vars to reduce object instance size, creation of classes and their VMTs dynamically at runtime (!!), pointer packing, multithreading, the list just goes on and on.
