Shardcraft

Overview

As I long time lover of Minecraft I always wanted to try working on my own voxel game and it was a ton of fun! Also a ton of work though, and so much time was spent on optimizing things so it would even run at all. I still work on it from time to time and plan to add creatures and crafting and inventory and all that... oh boy!

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
