AutoDungeon for GameMaker

AutoDungeon is a drop-in, fully-customizable 2D dungeon procedural generator for GameMaker that lets you turn a single line of code into sprawling, handcrafted-feeling levels. Whether you’re making a roguelike, Metroid-style map, or just need rapid prototyping, AutoDungeon handles the heavy lifting while giving you total control over room types, layout “feel,” and replayable randomness. The script returns a simple ds_grid of {real} values (-1 for empty cells, and then user-set values for the rooms themselves) Key Features Simple SetupJust instantiate: dungeon = new AutoDungeonGrid(size, totalRooms, totalUniqueRooms, uniqueRoomsArray, connectingRoomsArray, mandatoryRoomsArray); dungeon.generate_room([optional seed]) Flexible room pools Mandatory rooms (boss, special events, etc.) Unique rooms (shops, mini-bosses, treasures) with per-room spawn rates and max-per-dungeon limits Connecting rooms (generic corridors, hallways, filler) Reproducible randomness Optional seed parameter ensures you can save, share, or replay the exact same dungeon layout. Multiple build modes Blob – an organic, cave-like cluster of rooms Drunkard’s Walk – a winding, single-path “drunkard” carving from the start Manhattan Distance – crisp L-shapes radiating out from the center, with optional MST-style linkingEasy debugging & visualizationBuilt-in debug_draw_map(cellSize, spacing, showText) to instantly preview your grid in the GameMaker debugger. All methods in the AutoDungeonGrid, GridUniqueRoom, and GridConnectingRoom constructors are heavily documented Do you use GameMaker and interested in fast-tracking your development?
