GUI

The SFML GUI is a debugging and replay-inspection tool. It uses the same game engine and replay format as Python.

Build And Run

git clone https://github.com/FryOne2137/PolyEnv.git
cd PolyEnv

cmake -S . -B build \
  -DGAME_ENGINE_BUILD_GUI=ON \
  -DGAME_ENGINE_BUILD_APPS=OFF \
  -DGAME_ENGINE_BUILD_PYTHON_BINDINGS=OFF

cmake --build build --target game_engine_gui -j
./build/game_engine_gui

Run the executable from the repository root so it can find assets/ and data/Units.json. Building requires CMake 3.20+ and a C++20-capable compiler.

Save And View Replays

In a normal game, select Save .polygame from the File menu. Select Load .polygame to open a replay viewer.

The viewer is read-only and provides a timeline, Next move, automatic replay, and an adjustable playback interval. On macOS, load and save use the system file picker.

Game Rules In The GUI

The GUI shows legal actions from the engine. It blocks other actions while a city reward is pending. A city or village can be captured only by an own unit standing on it that has not moved or attacked this turn.
