Welcome to the GoldSource API docs

This documentation is an attempt on explaining inner workings of Valve's Half-Life (R) engine, also known as GoldSource, from programmer's perspective. A deep knowledge of Quake (NQ, QW and Q2) engines is required.

Everything discussed here is it's author assumption based on studying Xash3D source code and reverse engineering Half-Life mods. Xash3D API extensions is out of scope of this document and will be explained separately.
