indeed, i think i have seen SDK for 2008 studio.

by the way, soon will be released new engine. It will support ALL half-life content ( models, textures, maps, mods ) This engine is fully open source. It will bring Half-life mods to the next level.

Yep, it's Xash3D, it's legal, just usage of HL resources is not legal, so if u want to release mod like indie game you must replace all HL stuff with your.

It isn't publicly available. There are bits of Team Fortress Classic code in the client project though (mostly VGUI stuff, also some macros).

I'm pretty sure that the whole point of TFC was to demo the capabilities of the SDK. Surely there was source code.

tschumann Apr 25 2011 replied:

That was the point, yes, but the source code wasn't released. A lot of (maybe all of) its custom VGUI stuff is in the Half-Life SDK as it was new, but the rest of the code wasn't released, probably because the other features were already doable before the engine update that came with Team Fortress Classic.

They require command line arguments to do things. Try running them through cmd.exe to see what arguments they take.

If anyone is downloading the original Half-Life SDK and possesses any version of Visual C++ 2010, will not be able to open the project file(s) properly. The way to get it to run through Visual C++ 2010 (any version) is to at least download Visual C++ 2008 Express (or any other version will work if owned) and open it there. After converting it and saving it, then load it through Visual C++ 2010 (as stated, any version).

Now convert it and y'all should be able to use the original SDK with no problem. Of course it would be easier to use the Visual C++ 2008 version provided on here, but makes for a handy learning experience.

Edit: Oh yes, don't forget to make any changes when using the original. As stated of course, there is a provided Visual C++ 2008 edition that makes it easier.
