Certain game development blogs that are very likely to be dropped from my RSS feeds in the near future have been talking a lot lately about so-called "Entity Systems". This happens to involve a couple of axes I have to grind. It seems like another good example of how the Games Industry's locked-doors, no-academics, lets-brute-force-this attitudes have put blinders on the industry to decades of software engineering history and learning. "Entity Systems", as for instance described on the Entity Systems wiki, is a poorly renamed description of the prototype-based paradigm. (My Master's Project regarded this paradigm.) In object-oriented programming, prototype-based OO largely predates gaming's dominant class-based OO language (C++) and even the class-based paradigm as a whole...
I'd love to see the heads explode should some of these "Entity Systems" programmers sit down with a proper prototype-oriented language/environment that builds on decades of prototype-oriented knowledge. For instance: io.
(I am thinking about revisiting my Master's Project using the DLR more directly to build a fast prototype-oriented object model in .NET and see if I can rewrite some "Entity Systems" example into a more interesting shape (dot-notation and less "silly-DOM-model" API code smell). I would bet I could get it pretty fast and beautiful. Even if the DLR scares even professional .NET programmers, much less the C/C++ stalwarts.)
