Shardcraft

Overview

As I long time Minecraft enjoyer I always wanted to try working on my own voxel game. It was a ton of fun! Also very complicated with a lot of interesting technical challanges, so much time was spent on optimizing things so it would even run at all, hah!

Features

• Multithreaded generation/meshing/lighting using Unity job system
• Generation
• multifractal simplex noise generation, mountains and caves biome
• structure system for trees and gemstone structures
• 32x32x32 Chunk System
• chunks meshes are rebuilt whenever there is a change
• can add and remove blocks of course
• blocks are half the size of normal minecraft, so 8 times as much data :O
• greedy meshing to reduce unnecessary polygons
• Block Light Calculations
• supports RGB coloring, as well as a sky light channel
• ambient occlusion
• Voxel Physics
• voxel ray tracing
• voxel collision detection and response
• attempted this to be able to avoid expensive mesh colliders
• 3D A* Pathfinding
• Serialization system for saving and loading

Big thanks to my boy Ben and his work on Seed of Andromeda, from whom I have learned much. Here's some writeups which really helped me out:

• voxel lighting
• region file system
• procedural heightmap terrain
