Dynamic 2D Map Generator

Dynamic 2D Map Generator is a fully modular, editor-time generation system for Unity 2D that produces realistic, randomised city layouts at the click of a button. Built on layered pipeline road graphs, Wave Function Collapse tile placement, block subdivision, building placement, footpath rendering, and in-block prop population, it delivers richly detailed urban scenes without hand-crafting a single tile. Every subsystem is independently configurable: tweak road density, zone weights, building spacing, prop density, and terrain noise parameters all from a single inspector window. Results are fully Undo-compatible and work seamlessly with Unity's Prefab workflow.

Key Features

• WFC Road Layout: Wave Function Collapse ensures every road tile is socket-compatible with its neighbours, producing organic, gap-free street networks.
• Zone System: Assign weighted zone types (Residential, Commercial, Industrial, etc.) to city blocks. Each zone carries its own ground base tile palette, building prefab list, and in-block prop settings.
• Variety-Aware Building Placement: A multi-pass sweep fills blocks with large footprint buildings first, then 1×1 gap-fillers. A smart sorting algorithm tracks per-block and global usage counts along with a spatial memory radius to prevent repetitive building clusters.
• In-Block Prop Generation: Leftover empty cells after building placement are filled with zone-specific props or Global props. Supports multi-cell prop footprints with configurable density and spacing.
• Footpath & Perimeter Props: A perimeter-walk algorithm correctly traces L-shaped, U-shaped, and irregular block outlines for footpath tile stamping and prop placement.
• Procedural Terrain: Perlin-noise-driven outer terrain with configurable noise scale and threshold. A road-distance field smoothly blends city edges into wilderness.
• Full Undo Support: Every placed object and tile operation is registered with Unity's Undo system.

Note: The Demo Scene uses Built-in compatible materials to support both the built-in Render Pipeline and URP projects. The generator itself is pipeline-agnostic. Depending on your project setup, you may optionally adjust or convert materials/shaders after import.
