2.18.12 - [2025/12/10]

Fixed

- Fixed an issue causing tags to not be available on the `DoorwayProxy` objects

2.18.11 - [2025/11/25]

Changed

- Generating a dungeon in the scene view of the editor (using `Window > DunGen > Generate Dungeon`) will now spawn tiles as prefab instances, allowing for easier editing of generated dungeons

Changed

- All samples now switch seamlessly between the old Input Manager and the new Input System package

2.18.9 - [2025/08/28]

2.18.8 - [2025/08/20]

Changed

- Performance improvement when generating large dungeons or dungeons with many doorways

Fixed

- Tiles built with ProBuilder should now correctly have their bounds calculated when not open. Previously, ProBuilder bounds would only calculate correct bounds if the Tile was placed in the scene or open in a prefab stage

2.18.7 - [2025/08/14]

Fixed

- Doorways can now be marked as both an entrance and an exit at the same time, but a doorway cannot be used as an entrance if it would take the place of the only valid exit

2.18.6 - [2025/07/18]

Fixed

- Fixed a `MissingReferenceException` that could sometimes happen after importing DunGen

- PlayMaker integration now correctly uses the new `TriggerPlacement` mode enum instead of the deprecated `PlaceTileTriggers` boolean

2.18.5 - [2025/07/13]

Fixed

2.18.4 - [2025/07/10]

Changed

- Built-in culling and SECTR VIS integration now support dungeons generated attached to other dungeons

- SECTR VIS integration now caches portal meshes and disposes of them in OnDestroy()

Fixed

- Fixed an issue causing changes to not be saved when adding objects to a list by dragging and dropping them in the inspector

2.18.3 - [2025/07/05]

Fixed

- Fixed an issue causing tiles to spawn in the wrong position when the dungeon root object is not at the origin

- Fixed an issue causing debug tile visualisation GameObjects to stick around after the dungeon has been generated when 'Pause Between Rooms' is greater than zero

2.18.2 - [2025/07/02]

Added

- The `Dungeon` class now has a reference to the `TileInstanceSource` used for tile pooling. There's now a parameterless `Clear()` function that will return all tiles to the pool and clear the dungeon

Fixed

- The generation failure report window should now correctly display an error when a required tile could not be injected, causing the dungeon generation as a whole to fail

- Fixed an issue where multiple copies of the same door prefab would be added to the `Dungeon` component's list of doors

- Fixed a build error caused by `DunGenSettings` validation using editor-only methods

- Fixed some build-only warnings

2.18.1 - [2025/06/17]

Added

- Added support for 2D tile trigger placement

Changed

- Tile injection rules can now be re-ordered and collapsed in the inspector. This has no effect on the generation process and is purely visual

2.18 - [2025/06/10]

Added

- Doorway connector and blocker prefabs can now optionally use position & rotation offsets to correctly align the prefabs

- Added a new option for pooling tiles, improving performance when generating dungeons multiple times

- Added a `TilePoolPreloader` component that can be added into the scene to spawn instances of tiles that can be saved with the level and will be used to pre-warm the tile pool

- Added a `ITileSpawnEventReceiver` interface that can be implemented on any script to receive a callback when the parent tile is spawned or de-spawned. Useful for resetting state when using tile pooling

- Added `OnDungeonGenerationStarted` and `OnAnyDungeonGenerationStarted` events to the `DungeonGenerator` class

- Added a new window for displaying the stats of a generated dungeon (Window > DunGen > Generation Stats)

- Added functions for finding tiles by their tags to the `Dungeon` class: `FindTilesWithTag`, `FindTilesWithAnyTag`, `FindTilesWithAllTags`

- The `Dungeon` class now lists all branches via the `Branches` property

- DunGen settings can now be accessed from the project settings window (Edit > Project Settings...)

- Added a validation rule that warns when a tile prefab is missing a `Tile` component

- Enhanced path straightening options:

- Settings on `Archetypes` now include an option to straighten branches in addition to or instead of the main path

- Path straightening can now also be applied to nodes in the dungeon flow graph

- There are now global settings for path straightening on the `DungeonFlow` asset. These can be optionally overridden in `Archetypes` and on Nodes in the flow graph

- When the dungeon generation fails after reaching the maximum number of retries, a failure report window will now be displayed, showing all the reasons why the generation failed, and which tiles were involved. This can be turned off in the project settings

- Line segments in the dungeon flow graph can now be resized by clicking and dragging the boundary between two line segments

Changed

- [BREAKING CHANGE]: `IKeySpawnable` has been deprecated. Please update your code to use the new `IKeySpawner` interface instead

- Tile instantiation is now also asynchronous if 'Generate Asynchronously' is enabled in the generator settings

- PauseBetweenRooms is now automatically disabled outside of the editor so it won't affect the performance of builds

- Improvements to generation performance:

- Tile bounds are now pre-calculated in the editor to avoid performance overhead at runtime. By default, bounds are automatically recalculated each time the tile prefab is saved, but this can be turned off in the project settings. Bounds can be recalculated at any time using a new button in the Tile inspector

- Performance improvement will scale up with the number and complexity of tile prefabs

- Tiles are no longer deactivated before being destroyed

- Bounds from additional tiles that should contribute to collision avoidance are now cached at the beginning of the generation process

- Implemented a choice of broad phase for collision detection: None, Quadtree, or Spatial Hashing. NOTE: Quadtree is not recommended and currently only supports dungeons where the up vector is +Y

- Affects the MainPath and Branching phases. Performance improvement will scale up with the number of tiles in the dungeon

- Prospective doorway pairs are now sorted in a single pass, and custom connection rules are sorted once at the beginning of the generation process

- TileProxy objects are now pooled

- Various small performance improvements

- The option to include sprite renderers in the bounds calculations has been moved to the global DunGen settings asset

- Collision functionality and settings have been refactored into their own classes. Settings now belong in the `DungeonCollisionSettings` class

- The Dungeon class now has a `TileInstantiated` event that is fired when a new tile is instantiated

- Updated all samples to support tile pooling

- `DungeonGenerator`'s `GenerationStats` now contains information about how many of each type of tile were spawned, including how many were newly instantiated vs pulled from the pool

- Added assembly definitions for 'DunGen' and 'DunGen.Editor'

- Integrations for Unity's NavMesh Components and A* Pathfinding Project Pro no longer need to be manually extracted. They will be automatically enabled if the appropriate packages are present

- Added collapsible foldout categories to the dungeon generator inspector

- Selected node/line is now highlighted in the dungeon flow graph editor window

Fixed

- Custom connection rules should now be properly reset if domain reload is disabled in the project

- Fixed an issue in the Basic Sample causing many materials to be created when generating a dungeon

- Fixed an issue where the project would lose a reference to the default doorway socket

- The Doorway component should now always correctly revert to the default socket when no other is selected

- Labels on nodes in the dungeon flow graph editor should now correctly appear black in newer versions of Unity

- Removed remaining instances of deprecated `FindObjectOfType` and `FindObjectsOfType`

- Generating a dungeon attached to a manually placed tile (not spawned by DunGen) should now work as intended

- Fixed `NullReferenceException` when placing Doorways in a hierarchy with no `Tile` component

- The path straightening chance in the `DungeonArchetype` should now work as intended

- Fixed `NullReferenceException` when using empty entries in `LocalPropSet` component

Removed

- Removed support for versions of A* Pathfinding Project Pro before 5.0

- Removed RAIN AI integration
