Change Log / Unreal Engine

Version 2.31.0 Release Notes [14-Oct-2023]

  • New: Snap Connection Selector Blueprints - Apply this blueprint on your snap connection theme graphs. These blueprints give you access to the two room category it connects to and are great for selecting special doors for certain rooms (like boss / treasure rooms)
  • New: Dungeon Streaming Events - Any actor inside the snap modules can listen to dungeon chunk streaming events (loaded, unloaded, visible and hidden) by implementing the interface DungeonStreamingChunkEventInterface
  • New: Dungeon Streaming Actor Serialization - Save the state of any actor in a snap chunk while loading / unloading by implementing the interface DungeonStreamingActorSerialization. Check the SaveGame flag on any variable that needs serialization
  • New: SGF Procedural fill sample. Create only the main rooms (like boss, treasure, shop and spawn) and have the rest of the space in between procedurally generated
  • New: Run Marker Emitter blueprints either before or after the pattern matcher, thereby controlling access to the marker on the other system. If you want the marker emitter blueprint to have access to the pattern matcher emitted markers, run it after the pattern matcher executes
  • New: SGF Module Selector blueprints allow you to select or filter out the modules before being placed. E.g. Add (or don't add) the pillar variation of the room depending on whether there's another room on top of it
  • New: Snap Map builder supports module rotation on individual modules (similar to SGF), instead of having a single global flag to allow / disallow rotation of modules
  • New: Node Coordinate input has been added to the Flow Graph Module Category selection blueprint. This allows you to decorate your dungeons based on where they are (e.g. a different look on each floor, or a different room type on the edges)
  • New: Grid Flow Query has a new node to return connected chunk node coords, to allow traversal across the flow graph
  • New: SGF sample that uses the new module selector to add pillars if there's another module on top of it
  • New: Blueprint node DARecreateActorInLevel to recreate actors from snap module level to the persistent level. If you have dynamic actors that are part of a snap module (e.g. a weapon that you can pick up or an NPC), it would disappear when the level streams out. Use this node to recreate the actor in the persistent level
  • Fix: Theme Engine crashed in some instances when nested markers were used on larger theme files
  • Fix: Landscape Modifier class's properties are exposed to blueprint

Version 2.30.0 Release Notes [08-Sep-2023]

  • New: Snap Connection Entrance and Exit Constraints. Setting a door constraint to Entrance would ensure that we do not exit the room from this door. These are great for puzzle games
  • New: Pattern Matcher rule graph has a new MarkerListExists node that takes in a list of markers and performs a logical OR on it. This reduces the number of nodes you need to create
