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. ...
I wanted to share a quick update regarding the Clipper 2D library I’ve been working on. Initially, my goal was to fully reimplement Clipper2 with various optimizations. Over time, the project evolved into a streamlined version tailored for use in my game engine, focusing on efficient boolean operations on polygons with improvements in memory management and performance. Given that I have two larger projects that require my attention, I’ve decided to pause further development of the library. However, I’ve finalized a working version, which is available in its repository. It successfully performs the core polygon operations I originally set out to implement, and that was my primary goal. ...
While developing the navigation meshes for my game, I ran into a persistent issue: clipping polygons. I initially implemented a polygon subtraction algorithm that worked well for most cases, but it quickly became apparent that there might be a better approach to polygon clipping. Inspiration from Godot Engine After taking a short break from game development, I decided to dig into the Godot game engine, specifically its latest version, which includes navigation mesh support. After setting up everything in the debugger, I discovered the library Godot uses for polygon clipping. At first, I was confused by how it worked and why it was implemented that way. But after reading the documentation and doing some research, I gained a clearer understanding. ...
