VirtualGamePad Server

This is a part of the VirtualGamePad project.
The source is available at https://github.com/kitswas/VirtualGamePad-PC.

History of the server's development

1. The server was orginally writen in C++.
2. Then I rewrote it in Rust with windows-rs for Rust's memory safety and the newer Gamepad injection Windows support.
3. Windows.UI.Input.Preview.Injection, as the name says, is in preview and is buggy. (Read unusable)
   I, unfortunately, didn't know the source of the problems and decided to rewrite the app according to the Microsoft recommended way for Windows Apps (C# with WinUI 3 and the Windows App SDK).
   This is also when I figured that a GUI is worth the effort.
4. Finally, due to the aforementioned reasons, this was created in C++ with the Win32 API and Qt6 for the UI.

How it works

1. A socket connection is established between the client and the server.
2. The server uses the SendInput() function to synthesize keystrokes, mouse motions, and button clicks depending on the input from the client.
   It has the following implications:
   • The virtual gamepad is not limited to games. You can use the virtual gamepad to control any application on the computer.
   • Games that use DirectInput or XInput do not recognize input from the virtual gamepad as gamepad input but as keyboard and mouse input.
3. User defined keymaps are supported. You can create keymap profiles for different games or applications.

Build Instructions

Prerequisites

• Qt 6.8
• CMake

Cloning and Building

Clone the repository and submodules.

git clone --recurse-submodules https://github.com/kitswas/VirtualGamePad-PC.git

Open the project (open the CMakeLists.txt file in the project root) in Qt Creator and build it.

If you are using VSCode, you can use the Qt C++ Extension Pack. Remember to run 'Qt: Scan for Qt Kits' after installing the extension.

Code Formatting

This project uses clang-format for code formatting.
It includes a PowerShell script to format the code. Run

./code-lint.ps1

from the project root to format the code.
Note: This script requires clang-format to be installed and available in the PATH.

Generating Documentation

This project uses Doxygen to generate documentation.
If Doxygen is available on your system,
You can generate the documentation by running the following command:

doxygen Doxyfile

This repository has automated workflow via Github Actions.
Documentation is auto-generated and deployed to Github Pages.
