Source SDK

This is my fork of Valve Software's 2013 Source SDK, which I use as a base for my own source engine projects.

This fork contains bug fixes, QoL improvements & even some new features (some of these I may/may not have stolen from the official Source SDK's pull request page :P).

CONTENTS

FEATURED GAMES

REQUIREMENTS

Windows

  • Microsoft Visual Studio 2022 with the following workflows & components:
    • Desktop development with C++ workflow
    • MSVC v143 - VS 2022 C++ x64/x86 build tools (Latest)
    • Windows 11 SDK (10.0.22621.0) or Windows 10 SDK (10.0.19041.1)

Linux

BUILD INSTRUCTIONS

Windows

  • Inside the src directory, run: 
    createallprojects.bat
    This will regenerate the Visual Studio Project Files with any changes you have made to the VPC scripts and will generate new project files if they don't exist or couldn't be found.
  • Open the Solution (everything.sln) in Visual Studio.
  • Make sure that the Platform Configuration is set to Release instead of Debug.
  • In the menu, go to Build -> Build Solution or press Ctrl + Shift + B.

Debugging

  • To start debugging your source engine project, press F5 or click the Local Windows Debugger button with the green arrow to start debugging inside of Visual Studio.
    • Make sure that the client project is selected as the startup project otherwise the debugger will not work correctly

Linux

  • Inside the src directory, run: 
    ./buildallprojects
    This will compile your project automatically against the Steam Runtime.

Important

Mods that are distributed on Steam MUST be built against the Steam Runtime, which the above steps will automatically do for you.

LICENSE

The Source SDK and, by extension, the projects that you create are, by default, licensed under Valve's SOURCE 1 SDK LICENSE, which is contained in the LICENSE file at the root of the repository.

For information & guidance on distributing your mod on or off Steam, check the Source Engine distribution guidelines & FAQ.

Source SDK
This is my fork of Valve Software's 2013 Source SDK, which I use as a base for my own source engine projects.
This fork contains bug fixes, QoL improvements & even some new features (some of these I may/may not have stolen from the official Source SDK's pull request page :P).
CONTENTS
FEATURED GAMES
REQUIREMENTS
Windows
  • Microsoft Visual Studio 2022 with the following workflows & components:

    • Desktop development with C++ workflow
    • MSVC v143 - VS 2022 C++ x64/x86 build tools (Latest)
    • Windows 11 SDK (10.0.22621.0) or Windows 10 SDK (10.0.19041.1)
Linux
BUILD INSTRUCTIONS
Windows
  • Inside the src directory, run:

    createallprojects.bat

    
This will regenerate the Visual Studio Project Files with any changes you have made to the VPC scripts and will generate new project files if they don't exist or couldn't be found.
  • Open the Solution (everything.sln) in Visual Studio.
  • Make sure that the Platform Configuration is set to Release instead of Debug.
  • In the menu, go to Build -> Build Solution or press Ctrl + Shift + B.
Debugging
  • To start debugging your source engine project, press F5 or click the Local Windows Debugger button with the green arrow to start debugging inside of Visual Studio.

    • Make sure that the client project is selected as the startup project otherwise the debugger will not work correctly
Linux
  • Inside the src directory, run:

    ./buildallprojects

    
This will compile your project automatically against the Steam Runtime.
Important
Mods that are distributed on Steam MUST be built against the Steam Runtime, which the above steps will automatically do for you.
LICENSE
The Source SDK and, by extension, the projects that you create are, by default, licensed under Valve's SOURCE 1 SDK LICENSE, which is contained in the LICENSE file at the root of the repository.
For information & guidance on distributing your mod on or off Steam, check the Source Engine distribution guidelines & FAQ.
