Of Cyclical Rewriting

Sometimes I wonder why I even bother. It all started because there was a bug in the NTL compiler apparently not recognizing handler tokens. I could have sat down and probably fixed it in a bunch of hours. But no. I had to put the whole NTL language idea aside (as I said to Zak, it was mainly a "programming masturbation", but a cool one ;( ) and fall back to XML.

Well, I think it's eventually a good choice since XML is widespread, can be read by almost anything, espresso machines included, and is an accepted standard.

Luckily I didn't have to rewrite all the code that actually creates CLR assemblies out of the entity system definitions you spam in, or it would have been serious pain. Much pain.

Anyway. While I was at it, I also removed a feature which I didn't like. When the entities were processed and turned to IL, they were added a field named Prototype, which contained an EntityPrototype object basically describing the objects referenced by the entity; this means components, handlers and handled messages. All of this just to speed up entity creation at runtime.

However, I had forgotten once again about Attributes, and why they're in the CLR. So, armed with loads of patience but handicapped by lack of proper sleep, I set to remove this prototype stuff and go on with attributes. Now I'm in the middle of realizing what's the next step.

The most annoying part is that I am storing Types via their TypeHandles (actually their RuntimeTypeHandle.Values ToInt32()ed); this basically means creating a type storage via indices; this so reminds me of the database stuff I have going on at work - though, when I started to ramble about entity systems, I kind of expected it.

I had a nice demo going on but it's no more. Raaargh. Here's hoping it won't be long until I have something actually doing its job again.

I'm out.

07 Sept. Edit: Well, it wasn't as bad as I initially thought. I managed to get things up and running again, now including some things like proper component installation and uninstallation. Since my programming life is full of happy gummybears again, I can commit some time to the actual entity system editor. I'll keep you posted.
