Raycaster engine

Warning

Forked from Bálint Kiss (@balintkissdev) at this repo!

Basically a remake of doom that can run anywhere were a C++ 17 compiler is able to work, even web browser!

Features

• Up/Down to move and Left/Right to turn around
• WASD to move and strafe
• M to toggle mini-map
• N to toggle "Night Mode" and display darkness and lighting effect
• I to toggle color invert
• SPACE to shoot

Requirements

• C++17-standard compatible C++ compiler
• CMake 3.16 or newer

That's all. The dependencies are automatically downloaded by Hunter.

Build

mkdir build
cd buildR
cmake ..
cmake --build . --config Release

For cross-compilation, you can use one of the CMake toolchain files.

TOOLCHAIN=cmake/toolchain/x86_64-w64-mingw32.cmake cmake ..

Emscripten support

This project can be built with Emscripten in order to be embedded in HTML. After you set up the Emscripten environment, issue these commands:

mkdir build
cd build
# Workarounds required for Emscripten and Hunter to work together on a local machine.
emcmake cmake \
  -DCMAKE_C_ABI_COMPILED=ON \
  -DCMAKE_CXX_ABI_COMPILED=ON \
  -DCMAKE_CROSSCOMPILING=ON \
  ..
emcmake cmake --build . --config Release
