Node-based procedural 2D map generator for creating customizable dungeons, caves, biomes, corridors, decorations, and Tilemap layouts in Unity.Procedural Map Generator is a visual node-based tool for building customizable 2D maps with Unity Tilemaps.Create dungeons, caves, mazes, islands, rivers, biome regions, corridors, ruins, hazards, vegetation, loot locations, patrol routes, secret passages, and other procedural layouts by connecting generation nodes in an editor graph.Generation is deterministic: using the same graph, dimensions, and seed produces the same result. Maps can be generated directly in the Unity Editor or at runtime through the included Map Generator Runner component.Floor, wall, and decoration content can use separate Tilemaps. Decoration nodes place content over existing floor tiles without replacing them. Directional walls, corners, biome transitions, tile variations, and multi-cell vegetation placement are supported.The package does not include third-party sprites or art assets. A lightweight demo scene creates simple procedural tiles in memory, while production projects can use any compatible Unity Tile or Sprite assets.The package includes documented example graphs, a node reference, setup instructions, source code, and EditMode tests. All generator settings and node graphs can be customized for different genres, including roguelikes, dungeon crawlers, strategy games, survival games, and top-down RPGs.• Visual node-based graph editor• Procedural dungeon, cave, maze, island, river, and noise generation• BSP room generation• Cellular automata cave generation• Random Walk and L-System generation• Simplex noise and Voronoi regions• Corridor generation and pathfinding• Flood-fill cleanup and wall thickness controls• Symmetry, erosion, threshold, terrace, and blur modifiers• Logical mask operations• Room classification and secret passages• Biome splitting and secondary-ground painting• Directional wall and corner transitions• Separate floor, wall, and decoration Tilemap support• Tile and Sprite variation support• Vegetation, carpets, traps, torches, loot, prefabs, stairs, and puzzle placement• Tree footprint and clearance controls• Minimap and fog-of-war data generation• Patrol route and spawn-point generation• Deterministic seed-based generation• Editor and runtime generation• Included Map Generator Runner component• Included demo scene and example graph assets• Complete source code included• English documentation and node reference• EditMode automated tests included• No third-party art or runtime libraries• Designed for Unity 6• Requires the Unity 2D Tilemap module• Uses UnityEditor.Experimental.GraphView for the editor interface
