# travisvroman/kohi

A game engine made as part of the Kohi Game Engine series on YouTube (and Twitch!), where we make a game engine from the ground up using C and Vulkan.

## What it is
Kohi is a 3D game engine written in C using Vulkan, built from scratch as part of an ongoing YouTube/Twitch educational series. It is explicitly a learning tool rather than a production-ready engine, and includes an asset pipeline, editor, and custom build system.

## Use cases
- learn how to build a game engine from scratch
- study a Vulkan renderer written in C
- follow a game engine tutorial series
- explore engine architecture and design decisions
- build a simple 3D game with a from-scratch engine
- see how an asset pipeline and editor are implemented

## When to choose
- you want to learn engine internals alongside video walkthroughs
- you prefer C over C++ and want a Vulkan-based engine codebase
- you want a royalty-free, Apache-2.0 licensed engine to study or modify
- you enjoy following live-streamed, trial-and-error development

## When to avoid
- you need a production-ready engine for shipping a game
- you want a mature toolchain, extensive docs, or guaranteed stability
- you need 2D-focused workflows or mobile/console targets today
- you want a large community-backed engine like Godot or Unreal

## Facets
- artifact type: framework
- maturity: experimental
- function: game-engine, graphics, gui, developer-tools
- domain: graphics, education, tutorials, cross-platform
- platform: windows, cpp, cross-platform
- tags: vulkan, c, learning-project, video-series, 3d-engine, handmade-style, game-development, linux, macos, gpu
