Dungeon Generator - Unity WFC Procedural Levels

Generate complete, connected dungeons from a seed, then art-direct the result without leaving the scene. Dungeon Generator combines a deterministic wave-function-collapse core with modular 3D construction, live terrain painting, stacked floors, runtime navigation, gameplay hooks, sharing, and editor tooling.

Build a dungeon in the Inspector, drive it from C#, or use the engine-independent model as pure data for a custom renderer. The included interactive demo exposes the generation, painting, themes, lighting, models, NavMesh, agents, gameplay, sharing, and export workflows in one place.

The package also includes a ready-to-use stone art kit, six live-swap themes, furnished room purposes, player and zombie examples, procedural audio, and complete source code, so it supports both rapid prototypes and deeper production customization.

WHY DUNGEON GENERATOR

• CONNECTED BY DESIGN - a post-solve connectivity pass adds legal doorways until every walkable region is reachable.

• DETERMINISTIC AND EDITABLE - seeds reproduce layouts while paint, erase, perturb, stamp, restyle, and undo tools let you direct the result.

• VERTICAL LEVELS - combine stacked floors, spiral stairwells, terraces, basement levels, bridges, and optional ceilings.

• PLAYABLE SYSTEMS INCLUDED - bake runtime navigation, spawn a click-to-move explorer and zombie population, and connect chests, traps, keys, and gates to your game logic.

• SOURCE INCLUDED - inspect, extend, reskin, or integrate the complete C# runtime and editor implementation.

⭐ KEY FEATURES

• Weighted WFC generation with propagation, backtracking, carving, decoration, and deterministic seeds.

• Rectangle, ellipse, diamond, and cross footprints with grid sizes from compact rooms to large layouts.

• Live Cave, Grave, Void, and Canal painting with local re-solving, exact tile stamps, wall editing, and undo.

• Stone, Crypt, Moss, Blocks, Rough, and Sewer themes that swap the generated dungeon in place.

• One to three solved floors connected by spiral stairs, with optional terraces and basement levels.

• Runtime navigation, route display, click-to-move player, and adjustable zombie population.

• Key-lock progression, furnished room purposes, treasure, chests, traps, gates, and event callbacks.

• Deterministic spawn rules for project prefabs based on depth, terrain family, chance, cap, and wall alignment.

• Shareable dungeon codes that preserve settings, solved tiles, and hand edits.

• Dungeon Designer window, minimap, overlays, validator, PNG export, and 2D rasterization workflow.

• Bundled modular art, themes, prop variations, procedural audio, demo scene, and WebGL-ready demo source.

• Model swapping for supported structural, prop, player, and zombie slots, including OBJ import paths.

HOW IT WORKS

• Create a generator from GameObject > Dungeon Kit > Dungeon Generator.

• Choose a seed, grid size, footprint, carving, floor, progression, decoration, and weight settings.

• Press Generate to solve the logical plan and build the modular dungeon under the component.

• Paint terrain, stamp exact pieces, select individual walls, swap a theme or model, and undo as needed.

• Bake navigation, spawn agents, attach project content through spawn rules, or query the plan from code.

• Save a dungeon code or export a 2D representation when the layout is ready.

WHAT'S INCLUDED

• Full runtime and editor C# source.

• WFC solver, plan data, generation settings, query API, and serialization.

• Modular stone meshes, textures, materials, prefabs, props, and six themes.

• Generator Inspector, Dungeon Designer, setup tools, minimap, overlays, and validation tools.

• Interactive demo scene with generation, painting, floor, theme, lighting, model, NavMesh, agent, and export controls.

• EditMode and PlayMode test assemblies covering the core and Unity-facing workflows.

• One self-contained HTML manual with setup, API examples, customization, troubleshooting, and support.

CAPABILITY BOUNDARIES

• The bundled visual kit is designed for the Universal Render Pipeline; use your own library assets when targeting another rendering setup.

• The runtime OBJ importer covers the supported demo swap slots; production import pipelines with custom materials, rigs, or formats remain project-specific.

• The included NPCs demonstrate navigation and wandering behavior rather than a complete combat or RPG AI framework.

• Online hosting is not included; the package supplies the demo source and a prepared WebGL build for deployment.

**THIRD-PARTY CONTENT**

None. The bundled stone art kit is not sourced art - its textures, meshes, materials and prefabs are baked by editor tools that ship inside the package (Tools > Dungeon Kit > Build Demo Assets), and the sound effects are synthesised by the included audio factory. No third-party fonts, images, audio, icons, shaders, DLLs, native binaries or third-party source code are included; see Third-Party Notices.txt file in package for details.

AI-ASSISTED CONTENT DISCLOSURE

Portions of the included C# source code were created with AI-assisted code-generation tools, primarily Claude Code and, to a smaller extent, GPT-based models via Codex. All AI-generated code was manually reviewed, modified, and integrated to ensure correctness, performance, maintainability, and compatibility with the overall project. These services are not required at runtime.

Features

• Weighted WFC solver with propagation, backtracking, deterministic seeds and a connectivity pass so every walkable region is reachable.
• Live painting: Cave, Grave, Void and Canal terrain with local re-solving, exact tile stamps, wall editing and undo.
• 6 live-swap themes: Stone, Crypt, Moss, Blocks, Rough and Sewer.
• 1 to 3 stacked floors with spiral stairs, terraces and basements.
• Runtime NavMesh, a click-to-move explorer and an adjustable zombie population.
• Gameplay hooks: key-lock progression, chests, traps, gates, events and deterministic spawn rules.
• Shareable dungeon codes, Dungeon Designer window, minimap, validator, PNG and 2D raster export.
• Complete stone art kit, procedural audio, demo scene and full C# source with tests.

Requirements

• Unity 6.0 or newer — built with Unity 6000.0.62f1.
• Universal Render Pipeline (URP), AI Navigation package.
