Unity voxel survival framework

Block World

A modular Unity asset for procedural block worlds, biomes, crafting, tools, enemies, animals, inventory, and save/load gameplay.

Get Started Explore Systems

The asset is designed as a playable starting point and as a creator-friendly framework. Most gameplay data is stored in ScriptableObjects, so blocks, biomes, recipes, tools, and spawn rules can be expanded without rewriting core systems.

Key Features

Procedural Worlds Chunk-based terrain with seeded height, mountains, ores, trees, and runtime expansion. Biome Rules Surface blocks, height offsets, tree settings, ores, and entity spawns per biome. Generated Blocks BlockData, world prefabs, drops, material setup, registry support, and break tuning. Crafting Shaped or shapeless recipes, crafting station blocks, result slots, and inventory inputs. Enemies and Animals Wander, chase, targeting, melee attack, health, death, and biome spawn rules. Save System Seed, player transform, inventory slots, and block changes saved as JSON.
