Roomcraft builds a whole dungeon from a seed, in the editor or while the game runs, with the kit you already have. It lays out rooms, corridors and floors joined by stairs, places your floor, wall, ceiling and doorway meshes, dresses the rooms with your props, and sets up a run: a start room, a boss room behind locked doors, a key, treasure in the dead ends. C++ throughout, open to Blueprint.
Two ways to build
Grid: rooms and corridors on a grid, built from the pieces in a theme. Match Grid To Kit reads your meshes' size and pivot, and Check Kit says what does not fit.
Your own rooms: actors or whole levels, joined door to door, turned to fit, never overlapping. Doorways nobody joined get a cap.
A run, already set up
Start, key, boss and treasure rooms, picked so the key can always be reached before the boss
Doors that open as players walk in and close behind them; locked doors until the key
Spawn rules: enemies, loot or traps by room role, more of them the deeper the room, no code needed
Every room reachable, on every floor, checked on each build
Grows as players walk
With your own rooms, the dungeon can start small and add a room behind a door when a player comes near, for roguelike floors and endless corridors. Rooms far from every player unload and come back as someone nears them. Only the order of the doorways travels, so a player who joins late gets every room grown so far.
Built for multiplayer
Only the settings travel. The server and every client build the same dungeon from the seed, checked by a hash of the layout, on listen and dedicated servers. Doors, the key and spawned actors replicate like any actor.
Navigation and minimap
Runtime navmesh with nothing to place in the level. Locked doors block AI until the key.
A minimap widget for your HUD: rooms by role, doors, locked doors in red, other players. With the explorer component, each player sees only what they walked, kept by the server.
In the editor
Every change in the Details panel rebuilds the dungeon, and Undo brings it back. Bake To Level writes the dungeon into the level in blocks for World Partition to stream.
