OpenAG

OpenAG is an open-source client of the Half-Life promod Adrenaline Gamer, completely rewritten from scratch on latest Half-Life SDK. It adds new features, bugfixes and other tweaks over the original mod, while maintaining the ability to play on all currently existing servers.

Building

Windows

Visual Studio 2019 & Visual Studio 2022

Install Visual Studio 2019 or Visual Studio 2022. In the Visual Studio Installer, select Desktop Development for C++.
Open Visual Studio.
On the starting screen, click "Clone or check out code".
Enter https://github.com/YaLTeR/OpenAG.git and press the Clone button. Wait for the process to finish.
You can build the project using Build→Build All. To find the built client.dll, go to Project→CMake Cache (x86-Debug Only)→Open in Explorer.

Visual Studio 2017

Install Visual Studio 2017. In the Visual Studio Installer, select Desktop Development for C++.
Open Visual Studio.
Go to File→Open→Open from Source Control.
Click Clone:

Enter https://github.com/YaLTeR/OpenAG.git and press the Clone button. Wait for the process to finish.
You can build the project using CMake→Build All. To find the built client.dll, go to CMake→Cache (x86-Debug Only)→Open Cache Folder→OpenAG.

Manually using Git and CMake

Install Visual Studio 2017 or above, Git and CMake. Make sure to add them to PATH.
Clone the repository.
Open Git Bash in the OpenAG folder.
git submodule update --init
cmake -A Win32 -B build
cmake --build build --config Release

macOS

Install Xcode.
Install CMake via Homebrew.
git submodule update --init
mkdir build
cd build
cmake ..
cmake --build . --config Release

Linux

GNOME Builder

Set up Flathub by following the guide for your distribution.
Install GNOME Builder.
Open GNOME Builder.
Press the Clone Repository button, enter https://github.com/YaLTeR/OpenAG.git and press Clone Project. Wait until it finishes.

The cloning window should close, and a new window with the OpenAG project should open.
If Builder prompts you to install missing SDKs, press Install and wait for the process to finish. It will take a while. You can monitor the progress by pressing the circle in the top-right.
Click on the bar at the top-center which says OpenAG, and click the Build button.
Once the build finishes, in the same bar menu click the Export Bundle button. The file manager will open in a path that looks like gnome-builder/projects/OpenAG/flatpak/staging/x86_64-master. Navigate up to the OpenAG folder, then down to builds/pro.openag.OpenAG.json-... where you will find the built client.so.
Now you can make some changes to the code and press Build, then grab client.so from the same folder.

Manually

Get a 32-bit/multilib gcc (6 and above) or clang (3.9 and above) build environment set up, as well as CMake.
git submodule update --init
mkdir build
cd build
cmake ..
cmake --build . --config Release

Please use this repository to report bugs and feature requests for Half-Life 1 related products.

Reporting Issues

If you encounter an issue while using Half-Life 1 games, first search the issue list to see if it has already been reported. Include closed issues in your search.

If it has not been reported, create a new issue with at least the following information:

a short, descriptive title;
a detailed description of the issue, including any output from the command line;
steps for reproducing the issue;
your system information.*; and
the version output from the in‐game console.

Please place logs either in a code block (press M in your browser for a GFM cheat sheet) or a gist.

* The preferred and easiest way to get this information is from Steam's Hardware Information viewer from the menu (Help -> System Information). Once your information appears: right-click within the dialog, choose Select All, right-click again, and then choose Copy. Paste this information into your report, preferably in a code block.

Conduct

There are basic rules of conduct that should be followed at all times by everyone participating in the discussions. While this is generally a relaxed environment, please remember the following:

Do not insult, harass, or demean anyone.
Do not intentionally multi-post an issue.
Do not use ALL CAPS when creating an issue report.
Do not repeatedly update an open issue remarking that the issue persists.

Remember: Just because the issue you reported was reported here does not mean that it is an issue with Half-Life. As well, should your issue not be resolved immediately, it does not mean that a resolution is not being researched or tested. Patience is always appreciated.
