A stubborn attempt to build a game engine from scratch. Introduction After several years of learning, experimenting, and slowly turning a Handmade Hero practice project into something independent, Kaban Engine is now public. It is early, imperfect, and incomplete, but it represents a real foundation to build on. The goal of publishing it now is not to claim it’s ready, but to let the development become open and visible.

About a year ago, I joined Replay Golf Supply Inc. as a Golf Ball Technician. The work was simple but repetitive — sorting and counting golf balls by brand, sub-brand, and quality. It didn’t take long to notice how manual the entire process was. Counting thousands of golf balls by hand was slow, error-prone, and exhausting. The first thought that came to mind was: why isn’t any of this automated? ...
In my previous blog post, I explained what navigation meshes are and why they’re essential for my game. In this post, I’ll walk you through how I implemented this functionality in my game engine, breaking down the process step by step. Step 1: Creating Native Polygons The foundation of the navigation mesh is a set of “native” polygons that define all walkable areas in the game. I call them “native” because the mesh generation process relies on them. To create these polygons, I added tools to draw, edit, and save them within the engine. For now, this manual approach works well since the map is relatively small, but I’m considering automating this process in the future to handle larger or more complex maps. ...
Over the past few weeks, I’ve made significant progress on the navigation mesh system for my map editing mode, a core feature for creating interactive game levels. This post dives into why I chose navigation meshes, the details of what I’ve built, the challenges I’ve faced, and the next steps I’m tackling. For those unfamiliar, the map editing mode in my game engine allows users to design game environments, including ground tiles, entity placement, and navigation meshes. My current focus is on navigation meshes, which are critical for enabling entities to move intelligently within the environment. Let’s explore the motivation behind this choice and my recent progress. ...
In my last post, I talked about how my game engine loads assets from an asset file. To make it easy to tweak these assets, I built an Asset Editing System. This system lets users make small changes to assets and save them back to the asset file. It’s split into different “modes” for each asset type, like BitmapMode, SoundMode, SpritesheetMode, and others. In this post, I’ll explain the system’s main features and go over each mode. ...
