Carrot

Game engine in C++, mostly for my own fun.

Don't expect support for the moment.

Compiled with Visual Studio 2022.

Structure

core: Core code. Basic functions such as IO, logging. Also serves as de-duplication of code between offline tools and the engine code.
engine: Engine code
- engine/engine: Engine implementation
- engine/resources: Resources used by the engine (or left over from old code).
- engine/tools: Particle editor code. Should move to editor/ at some point.
asset_tools: Tools used to prepare assets.
editor: Peeler editor code and resources.
samples: Directories of different samples for Carrot.

Dependencies

What you need to install

Vulkan: Graphics API
Lua: LuaJIT and Vanilla Lua are both supported by sol3 (C++ lib for Lua support).
Mono: Carrot engine uses Mono to run C# code. Using mono-6.12.0.182 at the time of writing

asio: Networking lib.
Assimp: asset importing lib, used to load models
dr_libs: Audio codecs
GLFW: Cross-platform window & input API.
GLM: Math lib
Dear ImGui: Immediate mode GUI

sol3: Lua <-> C++ support
OpenXR: XR (AR+VR) API.
rapidjson: Json support
stduuid: Cross-platform UUID lib.
Tracy: Profiler.

Building

VR requires building manually thirdparty/OpenXR-SDK-Source

Use XR_API_LAYER_PATH=<path to Carrot>\thirdparty\OpenXR-SDK-Source\build\win64\src\api_layers as an environnement variable to enable api layers. Change win64 by your platform if necessary.

Assimp

Assimp broke FBX animation timing "recently", so the Assimp dependency is my fork, with the commit reverted.
