https://doc.cdryx.net/CdryxAIOUPlugin/modules/croomumodule/metadata/index.html Overview Metadata classes store runtime data attached to each cluster and room rectangle. They extend UCAbstractRectangleMetadata from CCOREUMODULE. UCClusterMetadata Attached to each cluster FCRectangle during finalization. Name Description tag Cluster tag inherited from FCRoomMakerStruct::mainTag fogOfWar FCRectangle representing the fog of war zone (computed from cluster bounds) roomMakerStruct Pointer to the source FCRoomMakerStruct configuration specificTopography Optional UCNoisator for per-cluster terrain noise specificShiftTopography Optional UCNoisator for per-cluster shift noise recalculateAll Recomputes the fog of war rectangle from the cluster bounds metaMargeForBetterWorldEasing Static helper that expands cluster bounds for smoother world easing // UCClusterMetadata is created during finalize_sync for each cluster. // fogOfWar is computed from the cluster bounds with a 5% overflow: // a = (2*origin.a + origin.b) / 3, b = (2*origin.b + origin.a) / 3 // then expanded by overflow factor. // metaMargeForBetterWorldEasing doubles the cluster extent: // a_out = a + (a - b), b_out = b + (b - a) // This ensures smooth terrain easing around cluster boundaries. // Per-cluster noise is optional: if (cMd->roomMakerStruct->clusterSpecificNoise) { UCNoisator::instanciate(this, noisator, seed, cMd->roomMakerStruct->clusterSpecificNoise->fastNoiseStruct, cMd->roomMakerStruct->clusterSpecificNoise->noiseStructArray); cMd->specificTopography = noisator; } UCRoomMetadata Attached to each room FCRectangle during finalization.
