As promised, here is the server plugin source code...
www.botman2.com/downloads/HPB_bot2_Alpha_1.zip
You will need to have created a Mod first (using Steam "Play Games" and double-clicking on "Source SDK", then double-clicking on "Create a Mod", and choosing "Start a mod from scratch").
Unzip the .zip file into your "MyMod/src/utils" folder and read the ReadMe.txt file found in the "MyMod/src/utils/HPB_bot2" folder.
Have fun!!!
