Nah okay. You should start a new thread for that. We'll help you compiling the stuff.
First, if you get the metamod plugin version, you have to get the metamod source code too, and the Half-Life SDK. But instead of doing that, we advise you to grab the HL bot compile pack we built up here at Bots United to ease a beginner's work. You can get it from
here
Once you have done this, you can open the project file (.dsw or .dsp) file with Microsoft Visual C++ and hit F7 to compile the bot DLL, and it should compile without error
*edit* I updated the HL bot kit in the filebase with the latest sources. You can go for it eyes shut.
