Arc Game Engine

About

Arc Engine is an in-development game engine written in C++.

I develop it in my spare time as a personal project, so expect frequent periods of time with no activity in this repository.

Set up

• Clone Arc Game Engine using git. Make sure you do a --recursive clone!

git clone --recursive https://github.com/MohitSethi99/ArcGameEngine.git

• Arc Game Engine is built in a Windows environment, using Visual Studio 2022.
• Execute the script scripts/Win-GenProjects.bat to generate the solution and project files.

Current Features

Right now, Arc Game Engine is very bare-bones. Its most remarkable features are:

Feature	Description	Status
Scene system	Scene-based entity management. Scene serialization with YAML.	Done ✔️
ECS support	Entity Component System approach through entt.	Done ✔️
2D Renderer	2D batch renderer supporting OpenGL.	Done ✔️
3D Renderer	Basic 3D renderer with lighting, IBL and PBR workflow supporting OpenGL.	Done ✔️
ImGui support	Basic game editor and in-game debug UI using dear imgui.	Done ✔️
Shadow Support	Soft and Hard shadow support in OpenGL 3D Renderer.	Done ✔️
2D Physics	2D Physics using Box2D with Rigidbody, Box and Circle Colliders and joints.	Done ✔️
3D Physics	Basic 3D Physics using Jolt Physics with Rigidbody, Box and Sphere Colliders.	Done ✔️
Scripting	Basic scripting in C# using mono.	Done ✔️
Audio	Basic Sound API with spatialization through miniaudio.	Done ✔️

Planned Features

Feature	Description	Status
C# API	C# API for all the components.	WIP 💻
Extended 2D Physics	Extend 2D physics to support more collider types and API.	WIP 💻
Extended 3D Physics	Extend 3D physics to support more collider types and API.	WIP 💻
Font	Extend the Renderer capabilities so it can draw text.	WIP 💻
Advanced Audio	Advanced Sound API with effects.	TODO 📋

Dependencies

Arc Game Engine has the following dependencies:

• assimp for loading meshes.
• box2d for 2D physics.
• dear imgui for GUI rendering.
• EABase dependency for EASTL.
• EASTL replacement for stl.
• entt for ECS management.
• Glad for OpenGL rendering.
• GLFW for OpenGL, OpenGL ES, window creation and input handling. More info at its website.
• glm as math(s) library.
• ImGuizmo for in editor transformation gizmos.
• Jolt Physics for 3D physics.
• miniaudio for audio.
• mono for C# scripting.
• optick for profiling.
• spdlog for logging.
• stb_image.h for loading textures.
• yaml-cpp for scene serialization in YAML.

Projects are generated with Premake 5.
