Sonic Frontiers DevTools

This is an in-engine modding toolkit for the SEGA game Sonic Frontiers. Releases can be found on GitHub or on the project's GameBanana page. A HMM update server is also available.

Setting up the development environment

Using Visual Studio 2022's CMake integration

You will need to have the following prerequisites installed:

• Visual Studio 2022

Check out the project and make sure to also check out its submodules:

git clone --recurse-submodules https://github.com/angryzor/sonic-frontiers-devtools.git

Simply open the project folder in Visual Studio 2022 (File > Open > CMake...) and it should automatically detect the CMakeLists.txt file.

The following presets are available:

• x64 Debug: Debug build.
• x64 Debug ImGui Demo: Debug build with ImGui demo window enabled (for editing themes etc.).
• x64 Release: Release build.
• x64 RelWithDebInfo: Release build with debug information.

Using CMake with the Visual Studio 2022 generator

You will need to have the following prerequisites installed:

• Visual Studio 2022
• CMake 3.28 or higher

Check out the project and make sure to also check out its submodules:

git clone --recurse-submodules https://github.com/angryzor/sonic-frontiers-devtools.git

Now let CMake do its thing:

cmake -B build

If you have Sonic Frontiers installed in a non-standard location, you can specify that location with the DEVTOOLS_GAME_FOLDER variable:

cmake -B build -DDEVTOOLS_GAME_FOLDER="C:\ShadowFrontiers"

Once CMake is finished, navigate to the build directory and open devtools.sln with VS2022. You should have a fully working environment available.

Building the INSTALL project will install the mod into HedgeModManager's Mods directory.
