The following is a procedural dungeon generator developed for my tutorial series which you can find here: https://sharpaccent.com/?c=course&id=25
It uses the Delanauy triangulation library from here: https://github.com/adamgit/Unity-delaunay
You can see the process here
The main concept for it is:
- Create cells and distribute them randomly.
- Separate those cells to make sure there's no overlaping cells
- Filter the rooms based on size and then triangulate between the ones we keep
- Create a spanning tree between them to make sure we can reach all cells in our generator
- Strict the spanning tree into horizontal and vertical lines to make paths.
- Visualize the results
The concept for this was inspired by: https://www.gamasutra.com/blogs/AAdonaac/20150903/252889/Procedural_Dungeon_Generation_Algorithm.php https://www.reddit.com/r/gamedev/comments/1dlwc4/procedural_dungeon_generation_algorithm_explained/
How to use
The project will rebuild libraries the first time you open it, this should take less than a minute. Afterwards open scene1 and hit play. It will generate a dungeon. You can enable debug mode from the generator asset, if you enable the debugview component you can take a look on the steps. Watch the videos on my site to see how to customize further and/or create a game out of it.
