  • Fedora packages

    cmake vulkan-headers ninja-build clang-devel llvm-devel libpng-devel
    

    • It's also important that you install the developer tools and libraries

      sudo dnf groupinstall "Development Tools" "Development Libraries"
      

Setup

Clone and initialize the Dusk repository

git clone --recursive https://github.com/TwilitRealm/dusk.git
cd dusk
git pull
git submodule update --init --recursive

Building

CLion (Windows / macOS / Linux)

Open the project directory in CLion. Enable the appropriate presets for your platform:

Visual Studio (Windows)

Open the project directory in Visual Studio. The CMake configuration will be loaded automatically.

ninja (macOS)

cmake --preset macos-default-relwithdebinfo
cmake --build --preset macos-default-relwithdebinfo

Alternate presets available:

• macos-default-debug: Clang, Debug

ninja (Linux)

cmake --preset linux-default-relwithdebinfo
cmake --build --preset linux-default-relwithdebinfo

Alternate presets available:

• linux-default-debug: GCC, Debug
• linux-clang-relwithdebinfo: Clang, RelWithDebInfo
• linux-clang-debug: Clang, Debug

ninja (Windows)

cmake --preset windows-msvc-relwithdebinfo
cmake --build --preset windows-msvc-relwithdebinfo

Alternate presets available:

• windows-msvc-debug: MSVC, Debug
• windows-clang-relwithdebinfo: Clang-cl, RelWithDebInfo
• windows-clang-debug: Clang-cl, Debug

Running

Pass the disc image as a positional argument. Supported formats: ISO (GCM), RVZ, WIA, WBFS, CISO, GCZ

build/{preset}/dusk /path/to/game.rvz

If no path is specified, Dusk defaults to game.iso in the current working directory.

30 FPS on Debug

When compiled fully in a Debug the game runs too slowly to hit playable 30 FPS. To avoid this, you can set a CMake cache variable to optimize specific critical files without hampering debuggability in the rest of the program: -DDUSK_SELECTED_OPT=ON. When building for MSVC (Windows) you must also modify CMAKE_CXX_FLAGS_DEBUG and CMAKE_C_FLAGS_DEBUG to remove /RTC1 from the flags, like so: -DCMAKE_CXX_FLAGS_DEBUG="/MDd /Zi /Ob0 /Od" -DCMAKE_C_FLAGS_DEBUG="/MDd /Zi /Ob0 /Od"
