Introduction
Minecraft is my favourite childhood game, and my love for this game remains the same today. Its massive, dynamic world full of living creatures and unique game play fascinate me. So, I set out to create my own version of voxel world and learn the mechanics of my favourite game.
In this post, I explain how I built, optimized my voxel engine, and what I plan to update and improve in the future. I also explain how I implemented some game features, such as block placing and breaking.
However, this post is more like a documentation of what I've learned through the development of my voxel engine, rather than a simple overview of my side project. I expect this post to be long, and I recommend you to read the part you are interested in by clicking the content listed below:
