Offline Proxy

This repository contains the source code for a DLL proxy used by the Brave Frontier offline mod. The proxy enables connection to a local server and embeds the offline server itself.

Overview

The offline proxy is designed to facilitate offline gameplay for Brave Frontier by routing connections to a local server instead of the online service. This project is tailored for Windows users and includes specific compatibility and build requirements.

Compatibility

• Operating System: Windows 8 or later (32-bit only)

Requirements

To build the offline proxy, you’ll need the following tools:

• Compiler: Visual Studio 2022 or MinGW
• Build System: CMake 3.20 or later
• Dependencies: Ensure vcpkg is installed and configured (see Building section for details), with libcurl available.

Building the Offline Proxy

Follow these steps to clone, configure, and build the offline proxy. This will generate libcurl.dll, which is necessary for the proxy to function.

1. Clone the Repository
   Use Git to clone the repository:

   git clone https://github.com/decompfrontier/offline-proxy

2. Set Up the Build Directory
   Create and navigate to a build directory within the cloned repository:

   cd offline-proxy
   mkdir build
   cd build

3. Configure the Build with CMake
   Use CMake with a preset to configure the project. For testing with Visual Studio 2022, run:

   cmake --preset debug-vs ../

   • This preset is ideal for testing the Brave Frontier (BF) client with a local server using Visual Studio.

4. Build the Project
   Compile the project to generate libcurl.dll:

   cmake --build . --config Debug

   • After a successful build, you’ll find libcurl.dll in the bin/ directory of your build folder.

Build Presets

CMake presets allow you to configure the build for different purposes and compilers. Choose the preset that matches your needs:

Preset Name	Description
deploy-vs	Configuration for deploying to the BF client using Visual Studio as the compiler
deploy-mingw	Configuration for deploying to the BF client using MinGW as the compiler
debug-vs	Configuration for testing the BF client with a local server using Visual Studio
debug-mingw	Configuration for testing the BF client with a local server using MinGW

• Note: The debug-vs preset (used in the example above) is recommended for initial testing and development. Adjust the preset and configuration (Debug or RelWithDebInfo) based on your deployment or testing needs.

Extra cmake variables

You can modify some of the Proxy behaviour by defining the CMake variables defined here:

Name	Description	Default value
OFFLINEMOD_IP	Sets the server IP which the proxy would connect	127.0.0.1
OFFLINEMOD_PORT	Sets the server port which the proxy would connect	9960
OFFLINEMOD_DISABLE_HTTPS	Enables the patches that allows the proxy to connect to an insecure (HTTP) connection	1 (true)

Next Steps: Building the Game Client

Once you’ve successfully built the offline proxy and obtained libcurl.dll, refer to the Brave Frontier offline mod documentation for instructions on integrating the proxy with the game client and setting up the local server. This typically involves:

• Copying libcurl.dll to the appropriate directory in your Brave Frontier installation.
• Configuring the game to connect to your local server (details vary by mod version and setup).

For specific guidance, consult the Brave Frontier offline mod’s official repository or community forums.
