PhantomGrammar replacement rules are very flexible, but one limitation is that each rule always matches a fixed number of nodes. The algorithm for combining spatial and quest graphs at the end doesn't give very convincing results and I think his thinking moved on a lot to produce Unexplored. Unexplored: Unlocked Edition is a roguelite that feels like a roguelike. Dungeons, Hex & Maps - Collection by TheGiftOfGabes - itch.io They are literally a stand-in for something that will be decided more concretely later. Block Dodge Parry This lets the game reason about the cycles as a unit, so the generator can apply design patterns that exploit the topology. PhantomGrammar has specific operations for dealing with cellular automata like this. Players find a lock or obstacle, have to take a fixed path through the map to find the solution, and then return back to the beginning of the loop to see if it is now resolved. Fix serialization on generation for the replacers. Each 55 block then has special rules applied to it to give it a specific shape. VTT Ive spoken many times of the power of generating something abstract first and filling in the details second. rules So first up, how does the game build maps from the level graph? A tag already exists with the provided branch name. Taking inspiration from games like The Legend of Zelda, this algorithm generates dungeons by composing together cycles: circular loops of linked dungeon rooms designed to create a specific flow of gameplay. Locks aren't always padlocks on doors, and keys are not always physical keys. Yes. A cyclic graph/dungeon generator, based on Dr. Joris Dormans' talk about cyclic dungeon Plus the entrance to path B from the goal might be closed upon entry, forcing the player to complete the loop via A. The algorithm can be described in a few simple steps: First, we generate a graph (laid as a grid) with empty nodes. Theres a huge variety of structure, all randomly generated, but nearly every level is a tightly packed, interesting space. Theres also rules for making cycles longer, or adding dead ends. Players may experience that whole cycle as they play through it the first time, or just part of it as they head for the exit to the next level.

Publisher's blurb: [Cyclic Dungeon Generation] generates dungeons by composing together cycles: circular loops of linked dungeon rooms designed to create a specific flow of gameplay. Another important non-terminal pair is a Lock and Key. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. The patterns can be used to nest a new cycle inside of an existing one. Once the high-resolutionversion of the map is built, it then takes all of the extra information stored in the level graph such as the monsters that should appear in corridors, traps in specific rooms, and the keys and locks for the main puzzles. It doesnt necessarily require that the end result be a dungeon in a literal sense. Some locked doors with switches can be relocked by hitting the switch again. Now the trick is that this loop can then have a particular gameplay pattern embedded within it. Top free physical games tagged Generator - itch.io The basic idea is that instead of generating one path between nodes, it generates two of them, forming a cyclic loop. There are several types of cycles that can be used to construct a dungeon, such as lock and key or hidden shortcut.

Includes The Tomb Under the Tree - an adventure generated using the described process. This can mean adding a theme or property such as a style of the room to be used or a treasure chest that will appear in the room when the mission graph is translated into a playable dungeon.

Unexplored has multiple types of key/lock combos, and the idea of what key/lock combos are and how they're designed lifts from similar tropes found in the likes of classic Legend of Zelda games.
