To make my question clear and quick can I getIs the full low level source-code in C++ of Source Code by Valve with full implementation details?
WithC++ source code of the only support APIs involved being DirectX/OpenGLSource Engine available? ect..
The Source SDK is available free of charge via Steam with purchase of a Source-based game
I know According to Valvethe SDK is available with the purchase of a Source-based game.
Note: I have never worked with the engine or glanced at any snippets of it personally. My, but my goal is to find a open-sourced game engine that includes its full implementation details for learning purposes. I dont want to sound naive, hence am asking this question.
