Exactly what is an SDK?
 

Can someone explain to me what the SDK is? I'm not a complete newb, I just have no idea what this is and what is has to do with half-life.

Software Development Kit.

Valve released one for HL1 which let people make all the cool mods you see today ;]

Basically you can say its just a copy of the half life source code. People use it to modify the hl code (hence the word mod) to make their own games.

Erm, it's a copy of a part of the HL source code. Normally engine interface + base gamedll.

edit: :gyar:

Yeah yeah -.-

So when is SDK due for release?

There's no official date yet.

Well they said before the game ships. Unless they lied. :shock:

Like I said; no official date yet :D:D

It's all a giant ruse. There is no SDK. There never will be an SDK. Valve is just playing a prolonged April Fools' joke on the community. You'll see, there will be no SDK when HL2 ships, there will be no SDK by New Year, there will be no SDK by end of March, and on April 1st, Valve will put out a press release saying little more than "Suckers!".
