A Dungeon dimension generator for use with Open Terrain Generator. Used as a tech demo for the new custom structure (BO4) features of OTG 1.12.2 v1 and 1.11.2 v8.
Some detail on the dungeons:
The dungeons underneath the ocean temple use the new BO4 branching mechanics for CustomStructures. 2 rooms (16x16 and 32x32) are repeated to create a large procedurally generated dungeon with branching passages and staircases. The branching mechanics guarantee that each passage leads back to the beginning of the dungeon and that there are no unreachable or overridden rooms. Using the new branching mechanics structures like these dungeons can grow like the roots of a plant, via collision detection and rollback mechanics dungeons resize themselves to neatly fit inside a space, just like a plant grows to fill a pot. The 16x16 rooms have randomised interiors and blocks and have their walls and/or ceilings randomly punched out if there is a neighbouring room. Mob spawners and particles have been added to interiors as a demonstration. The dungeons are configured to never extend beyond the footprint of the temple above, and can be configured to never extend beyond world borders while the temple above could. Because the entire dungeon is made of only 2 rooms it's a bit boring gameplay-wise at the moment, these dungeons are meant as an example and starting point for content creators so they can start making their own procedurally generated BO4 dungeons, caves, sewers, villages, cities etc. Documentation will be made available a.s.a.p.
How to reach the dungeon dimension:
Create a new world via the OTG world creation GUI and select the Dungeons preset, or use the ingame 'O' menu to add the dungeon dimension to an existing world. Build a chiseled stone brick portal to get to the dimension (portal blocks can be configured via O menu). After you leave the dimension you can delete it via the O menu. A dimension has to be unloaded for this, unloading should happen automatically shortly after the last player leaves the dimension. Use the O menu to show a list of dimensions and their status.
*Description in the worldconfig is outdated, please ignore. Will add documentation a.s.a.p.
