That's basically it. The idea is to have an editor which allows 
creating generic objects with dynamic attributes, eg, meshes, 
vectors, sounds, etc. Each object would have a basic state 
machine with each state being an order dependent list of 
"Command" objects. Command objects would be drag-n-drop style 
logic blocks with GUI properties (though keyboard editing would 
be a priority as well). Command objects would be represented in 
immediately executable core command objects (math, io, network, 
etc) but would get silently compiled into efficient D execution 
objects in a separate thread, then used instead. Advanced custom 
Command objects could also be hand written in D (preferably in 
editor).
Prebuilt command objects would be everything from simple 
transform manipulation and logic (lookat, IK chains, triggers, 
conditions, etc) to entire character control schemes (FPS, race 
car, etc).

Because all command property linking would be known by the 
editor, that information could be used to build efficient 
dependency graphs.

I'm still working out the kinks in the theory, but I feel the 
concept has potential.

D can get complicated real quick, but features like GC, auto 
keyword, and the lack of '->' makes writing simple functions 
easier to understand than C, IMO. Simple functions is basically 
the extent of what I have in mind for the editor, so it seems 
like a good fit.


Thanks for all the insight.

Awesome, didn't know about this.
