Change Log - Dungeon Architect for Unity

• New SGF Query has new functions to query the distance between any two nodes. E.g. You may use this to query the distance to the entrance / goal nodes while spawning your enemies. Check SnapGridFlowQuery.GetDistanceFromStartRoom and SnapGridFlowQuery.GetDistanceToGoalRoom
• New Sample for SGF Room Distance Query. Assets/CodeRespawn/DungeonArchitect_Samples/DemoBuilder_SnapGridFlow_QueryEnemy
• New SGF Landscape Transformer Sample - Blend a terrain around your SGF dungeons. Assets/CodeRespawn/DungeonArchitect_Samples/DemoBuilder_SnapGridFlow_Terrain

• New SimpleCity builder supports pattern matcher
• New SimpleCity Sample that demos larger houses (that always face the road) generated using the pattern matcher. Assets/CodeRespawn/DungeonArchitect_Samples/DemoBuilder_SimpleCity_PatternMatcher/City_PatternMatcher_StrongholdMedieval.unity
• New SimpleCity builder supports rotation and is no longer fixed to the XZ axis. Rotate the dungeon game object and rebuild the dungeon
• New SnapConnection script's UpdateState function is made virtual. This allows you to extend the snap connection component with you own logic
• New Add decorative modules around your SGF dungeons using the Add Padding node. This adds new layout nodes around the edge of your dungeon, where you can place decorative background modules

• New Major new feature called Pattern Matcher. Capture patterns in your dungeon layout and add or remove markers around this pattern. This is a powerful system for decorating your themes, as you are no longer restricted to a single tile level decoration and can decorate across multiple tiles using your own patterns. Docs
• Fix Grid Flow chunk tiles were leaking over to unconnected nearby chunk tiles, bypassing key-locks
• New Navigation support to runtime generated SnapFlow dungeons
• New Improvement to item placement strategy scripts for grid flow. It gives you more information while placing your items in the chunks
• New Grid Flow Tilemap generation performance optimizations
• New Define custom gridflow exec nodes using simple scripts
• Fix Wall Half Separators were missing in certain cases
• Fix The editor doesn't allow the Result node to be deleted

• New Major improvements to the Snap Grid Flow builder algorithm. The performance no longer degrades considerably when using a larger graph (more than 1000+ nodes)
• New SGF builder now supports Door Categories. This allows you to have different door shapes and the stitching would happen only through the compatible connection points
• New SGF builder has a parameter NonRepeatingRooms to disallow the same room prefab from being stitched next to each other (or somewhere near it)
• New SGF Module database has improved weight selection logic. Specifying a higher weight on a certain module will have it show up more times in the final stitched dungeon
• New Launchpad sample: SGF Non repeating rooms - Disallow the same room from being stitched next to each other
• New Launchpad sample: SGF Door Categories - Use door categories to have different art assets for your doors (round doors, larger doors etc) and make sure only the compatible ones are stitched together
• New Launchpad Sample: SGF Visibility Graph - Shows how to setup the visibility graph so the rooms further away from the player are hidden, thereby improving rendering performance
• New Launchpad Sample: SGF Query Interface - Use the SGF query interface to know more about the dungeon and it's underlying graph. This sample detects the room the player is in and draws a bounding box around it in the scene view
• Fix SGF layout graph debug visualization was not rendering correctly for dungeons not placed in the origin

• Critical Fix Editor code in one of the samples was causing build issues
• New SnapGridFlow builder query interface
• New SnapGridFlow builder landscape transformer

• New SnapGridFlow visibility graph sample

• New Added Grid Flow Builder Query interface. Use this to decorate your grid flow dungeons in different ways (new samples added to launchpad)
• New Mirror node for Grid Flow builder
• New GridFlow and SnapGridFlow builders have the RetryOnFailure option exposed in configure. It's normal for dungeons to not converge on their first try (depending on how the flow graph was designed). Control the number of retries with this option
• New Added a Grid Flow builder flag to flip the walls and fences by 180 degrees so they work correctly with themes designed for grid builder (check advanced section of the config)
• New Snap Grid Flow builder has new nodes to expand an existing graph and add padding nodes around it. These are great for decorative rooms around your dungeon
• New Helper function in the dungeon component to randomize the seed from code
• Fix Flow editor's state is correctly re-initialized when it goes stale at certain events (like unity editor start, begin play)
• Fix Grid Flow walls were not aligned correctly in some cases when the wall was shared between rooms and caves
• Fix SGF dungeons correctly invoke the DungeonItemSpawnListener script when attached to the dungeon object
• Fix Snap Grid Flow connections stitch correctly when they are not placed at the root hierarchy of the module prefab
• Fix Grid Flow builder key-locks were not working in some cases where the wall mode was set to "WallsAsEdges"
• New Launchpad Sample adds marker and theme engine support in Snap dungeons

• New Launchpad Sample for placing items at the center of a room in a Grid Flow dungeon
• New Launchpad Sample that maintains a global state in the theme engine while building the dungeon

• Fix Snap Grid Flow Module bounds correctly calculates the module bounds. This was causing door connectivity issues in some cases
• Fix Flow graph's Key-Lock system was creating unplayable levels at times and has been fixed. The system does a comprehensive check where the algorithm walks through the graph, just like how a player would, picking up the keys along the way and opening the doors. It makes sure that every node is accessible and will work with nested key-lock setup
• Fix Optimized the performance of the path search algorithm with larger rooms and when the grid size is large
• Fix Optimized the performance of the Snap Grid Flow Dungeon's inspector window. Unnecessary data is no longer exposed, which was causing rendering issues
• Fix Optimized the rendering performance of the Snap Grid Flow Editor's 3D viewport. It redraws itself only when necessary and not on every tick
• Fix Disabled the serialization of the snap grid flow graph in the dungeon model. This was degrading the performance of the editor when the dungeon was built offline. Build the dungeon at runtime if you need the model information
• Fix Snap Grid Flow's Create Main Path and Create Path nodes were ignoring the script based Snap Module Constraints
• Fix All sample scenes upgrade to URP correctly. Upgrade your project from the menu: Edit > Render Pipeline > URP > Upgrade project materials to URP
• Fix Fix a null pointer error in the Snap Grid Flow editor window when the asset being editor was deleted
• Fix Launchpad's 2D Jack Rabbit game demo sample link was broken
• New Snap Builder has a flag to hide the duplicate doors when two adjacent modules connect. Disable it if you want two doors. This is useful on 2D tilemaps

• New Grid Flow builder's Create Main Path and Create Path nodes support position constraints. Use a script to control where the nodes are created in the flow graph. Sample added to the launchpad
• New Grid Flow supports static spawn / goal room positions. This allows you to blend your static level art with the procedural dungeon. Added a new sample in the launchpad demoing this
• Fix Module database is more fault tolerant while finding and assigning user defined connections during compilation. When your connections are off by a little, it will make a better guess of the right connection slot
• Fix Fixed the grid builder's paint data getting destroyed on dungeon rebuilds
• New New side scroller sample setup for snap grid flow builders in the Launch Pad

• New A powerful new builder called SnapGridFlow. It combines the power of the Flow and Snap frameworks and lets you stitch pre-made rooms using a powerful layout graph editor. More info here: https://docs.dungeonarchitect.dev/unity/snap-grid-flow
• New Theme Editor marker visualizers. Click on a theme node for alignment guides. Enable it with the Marker Visualization button in the theme editor's toolbar
• New Visibility Graph framework lets you hide snap based prefabs that are a certain depth away from the layout graph. This is great for improving the performance
• New Grid flow code and it's supporting editor infrastructure has been rewritten into a reusable flow framework (without breaking your existing gridflow assets). This will allow for future extensibility and paves way for many interesting new builders (with snap-grid-flow being the first of them)
• New Grid Flow editor and Theme editor nodes have had their property editors redesigned so they have a a more aesthetically pleasing look in the inspector window
• New Redesigned the UI renderer so all editor windows are fast and responsive. This includes the theme editor, snap editor, gridflow editor and snap grid flow editor
• New Discord and documentation buttons added to Theme Editor, Snap Editor, Flow Editor and Dungeon actors
• New Theme editor's visual nodes have their "Force static" set to false by default. This is an editor only flag and doesn't affect runtime builds. Change your prefab's mobility to affect the static state instead
