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/GloriousPtr/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 📋 | | Asset manager | Basic asset handling API. | TODO 📋 | | Direct3D | Extend the Renderer to support D3D12. | TODO 📋 |
