Entity Systems

What does /prog/ think about Entity Systems?

This is an old idea. It's really just Model-View-Controller with a different name and a slightly different spin.

Game object or game entity systems have been in use in game engines since the 90's. Hobbyist game developers talking about it in their blogs or on gamedev.net seem to think it's cutting edge stuff, but it's not at all.

Seriously, more game developers could use a bit of a reality check and a deep dive into enterprise development for a change. It'll help balance them.

As it currently stands, many game developers seem to live in a vacuum distanced quite a bit from everyone else. It's gotten to the point where some game developers are reinventing the wheel and coming up with different terminology and conventions completely askew to accepted nomenclature. It's quite laughable at best, and dangerous as there is a certain lack of rigor in their formalisms. They're more fly-by-the-seat-of-your-pants types of developers. Practical, pragmatic, but at times ignorant of past research and works in computing.

And there's certainly nothing wrong with reinventing the wheel, if you get a better a wheel in the end. I just wish more of them would show a little more respect for the rest of the field.

You might think I'm coming off as arrogant, but then, you've probably never met a real game programmer at a major game company.

#undef RULES
#define REBELS

I can't understand what the guy is going on about

That's not how the C preprocessor works. At all.

Can somebody show me a very minimal example of what this guy's talking about?  Maybe a little C or C++ program that uses a couple entities and components or something.

(the use of “methods” or “functions” is an idea that predates OOP by decades – it is coincidence that OOP *also* uses methods).

struct Compnent { entity list * };

THERE YOU GO

Noo, you've got to provide for optional data storage as well!
