Cube Mining: A 3D Voxel World in Defold

A 3D voxel mining example built with the Defold Game Engine. This project demonstrates how to handle dynamic voxel environments, efficient mesh generation, character and NPC physics.

This demo features a Greedy Meshing algorithm that merges adjacent faces into larger quads to reduce vertex count, a Swept AABB Collision System for interaction with the voxel world, and real-time interaction with block placement and destruction. Includes Golden Ore and unbreakable bedrock layers. The system includes Runtime Sprite-to-Mesh Voxelization that converts 2D pixel art sprites (like guns or swords) into 3D voxel meshes, and Performance Monitoring with player position tracking. Smart Culling excludes hidden faces to increase efficiency. The demo runs on a 16x16x16 voxel cube. Mesh generation currently runs on the main thread causing minor hitches during massive world updates as the buffer rebuilds.
