Procedural Dungeon Generator Lite

The Procedural Dungeon Generator is an easy to use, tile based dungeon generator for Unreal Engine. Built in blueprints, this is an easy to use tool to kickstart your procedural projects.

Plug in your own custom themes and decorations, then adjust the linearity and complexity of the dungeon to find the shape and style that fits your project.

Each path type has its own unique mesh pallet with an array for each building block to add even more variation. Add custom meshes for as many unique paths and rooms as you desire and even adjust the heights of the rooms pre-generation.

This project is free as a lighter version of the main Procedural Dungeon Generator Project. This version includes the main dungeon blueprint, Data Tables for editing Room/Path themes, functioning keys/doors and lights, and five example blueprints for adding procedural decorations.

This is the final version of the project supported in Unreal version 4.27 and does not include features added to the procedural dungeon generator from version 3.0 and above. If you like the generator and find it helpful in your project please leave a review on the Unreal marketplace and try checking out the full version.

Change Log

Fixes:
- Fixed issue when paths are enabled that would cause a default path to generate instead of an available themed path
- Fixed and issue that would cause default door frames to spawn in corridors between rooms of another theme
Fixes
- Fixed Decorations spawning repeatedly when using World Partitioning
- Fixed issue where hallway entrances that are culled are not added back to room when building halls
- Torches now adjust lighting to account for grid scale
- Fixed debug lines not despawning when debug mode was turned off
Changes
- Removed Door and Torch spawning functions
- Added Door actors to DT_RoomData as a Themed Decoration
- Added WallDecoration actor to DT_RoomData to replace Torches
- Removed Room Merging to prevent locked doors from being avoided
- Blocked rooms from spawning over corridors, spawning locked doors before the key (Corridors can still spawn through previous rooms creating looping paths)
- Updated Dungeon Entrances and Exit, adding corridors and restricting generation to avoid paths being blocked
Additions
- Added Key/Lock System
  - Dungeon can be assigned any number of key/lock combinations
  - Each room is procedurally assigned a locked door with the associated key spawning in the previous room, or any previous dungeon room.
  - Each room type can be assigned a themed key/lock combination in DT_Default_RoomData to be spawned instead of a random one. The Boss key always overrides procedural generation to guarantee the boss room spawns with the desired key.
  - Keys and Locks can be any desired blueprints
- Added Dungeon Paths
  - Dungeon generation can now be split into path segments of varying length until the desired dungeon length is reached.
  - Path segments can be generated linearly, or branch off of random rooms along previous paths
  - Path rooms have assigned keys and locks, allowing for controlled progression through the dungeon, even when backtracking or overlapping paths.
Fixes
- Fixed torches not being relative to world position when spawning
- Fixed hallway corners not being removed from intersecting rooms
Additions
- Add option for wall entrance and exit
- Adjust grid spacing and dungeon size with GridScale variable
- Add option to generate dungeon on Runtime
