https://doc.cdryx.net/CdryxAIOUPlugin/modules/croomumodule/croommaker/index.html Overview UCRoommaker is the core room generation engine. It implements ICCell, ICRoomBoundable and ICCoordBoundable. It generates clusters of rooms, connects them with MST-based corridors, assigns spatial cells for fast lookup, creates box collisions for overlap detection, and computes a longest-path ordering for progression. Instantiation Name Description instantiate Static factory. Creates a singleton UCRoommaker bound to a scene component, with a random stream and cluster configuration // Called by ACRoomSpawner::init() UCRoommaker::instantiate(GetRootComponent(), roommaker, stream, *data); Generation Name Description buildASync Entry point for async generation. Delegates to drawRoom then finalize_sync via queue drawRoom Generates all rooms and clusters: random placement, relaxation, Delaunay, MST, edge breaking, cell assignment createRoom Creates rooms for a single FCRoomCountStruct within a cluster finalize_sync Dequeues generation results and creates metadata (UCRoomMetadata, UCClusterMetadata) finishWorldObject Spawns box collisions per room after both room and world spawners are ready // buildASync is called on tick by ACRoomSpawner. // It runs drawRoom asynchronously, then finalize_sync on the game thread. roommaker->buildASync(singleDoRun); // drawRoom pipeline: // 1. For each FCRoomMakerCountStruct, create rooms with random positions // 2. Relax rooms using the configured CAlgoRelaxType until stable // 3. Relax clusters in a second pass // 4. Delaunay triangulation for room connectivity // 5. MST for corridor paths (straight or flex) // 6. Break edges with noise for organic corridors // 7. Assign rooms, clusters and edges to spatial cells // finalize_sync creates UCRoomMetadata per room (doors, tags) // and UCClusterMetadata per cluster (fog of war, specific noise). // After all clusters are finalized, longestOrderedPath computes // room ordering along the MST for progression. // finishWorldObject spawns UCRoomBoxCollision per room // for overlap detection (quest/skill triggers). Retrieval Name Description retrieveClusterById Returns a cluster FCRectangle by cluster ID retrieveRoomById Returns a room FCRectangle by cluster ID and room ID retrieveRoomDetailById Returns FCRoomDetailData for a cluster retrieveClusterByTag Returns all clusters matching a FName tag retrieveRoomByTag Returns all rooms matching a FName tag retrieveEdgeById Returns a corridor FCEdge by cluster ID and edge ID retrieveClusterByRoom Returns the parent cluster of a room via its metadata retrieveClusterMetadata Casts a cluster’s metadata to UCClusterMetadata retrieveRoomMetadata Casts a room’s metadata to UCRoomMetadata retrieveSpecificNoiseData Returns per-cluster specific noise and shift noise // Retrieve a room by IDs: FCRectangle* room = roommaker->retrieveRoomById(clusterId, roomId); // Retrieve all rooms with a specific tag: TArray<FCRectangle*> treasureRooms = roommaker->retrieveRoomByTag(FName("treasure")); // Get room metadata (doors, tag, consumption state): UCRoomMetadata* meta = roommaker->retrieveRoomMetadata(room); // Get cluster-specific noise for terrain modulation: auto [noise, shiftNoise] = roommaker->retrieveSpecificNoiseData(cluster); Iterators Name Description iterateOnCluster Iterates over all clusters. Callback returns true to break iterateOnClusterRoom Iterates over all rooms in all clusters. Callback returns true to break // Iterate all clusters: roommaker->iterateOnCluster([](FCRectangle* cluster) { // process cluster return false; // true to break }); // Iterate all rooms across all clusters: roommaker->iterateOnClusterRoom([](FCRectangle* cluster, FCRectangle* room) { // process room within its cluster return false; // true to break }); Geometry Finders Name Description closestCluster Finds the closest cluster containing a 2D point (cell-limited) closestRoom Finds the closest room containing a 2D point with optional tolerance (cell-limited) closestEdgeWithin Returns all corridor edges within a distance from a 2D point (cell-limited) closestEdge Finds the single closest corridor edge to a 2D point (cell-limited) nearEdge Finds the nearest edge within its influence width (cell-limited) fogOfWarPart Returns the fog of war rectangle for a cluster // Find closest room at a world position: FCRectangle* rect; if (roommaker->closestRoom(FVector2D(x, y), rect)) { // rect is the room containing or nearest to (x, y) } // Find corridor edges within 500 units: TArray<FCEdge> edges = roommaker->closestEdgeWithin(FVector2D(x, y), 500.0f); // Check if a point is near a corridor (within edge width): FCEdge edge; if (roommaker->nearEdge(FVector2D(x, y), edge)) { // point is within the corridor influence zone } Overlap & Interaction Name Description OnBeginOverlap Triggered when an actor enters a room box collision OnEndOverlap Triggered when an actor leaves a room box collision isRoomEligibleForTagProba Checks room content eligibility based on character tags and probability ranges longestOrderedPath Computes the longest path through the MST for room progression ordering // Room overlap triggers quest actions and skill consumption: // On begin overlap: checks quest system first, then skill system. // If interactWithPlayerOnly is true, only the player pawn triggers. // If canOnlyBeConsumedOnce is true, the room is marked consumed after first interaction. // Room eligibility for content: int contentCount; if (roommaker->isRoomEligibleForTagProba(contentCount, room, charMainTag, charTagArray, true)) { // room is eligible, contentCount indicates how many tags matched } Hugo en-us
