An implementation of the Snappable Meshes PCG technique in Unity with automatic generation of piece metadata.

The Snappable Meshes PCG technique consists of a system of connectors with pins and colors which constrains how any two map pieces (i.e., meshes) can snap together. Through the visual design and manual specification of these connection constraints (v1.0.0) or a new auto-generation approach (v2.0.0), as well as an easy-to-follow generation procedure, the method is accessible to game designers and/or other non-experts in PCG, AI or programming.

This repository contains prototype implementations of these techniques developed in the Unity game engine.
