Grid Path Steps

The Grid Path Steps are a family of floor generation steps. It is used exclusively in Grid Floor Generation. Their typical priority is -4.

Usage

Grid path steps are used to generate a path of rooms and hallways in grid floors. Each different variant of the step does so through different methods.

Variants

The following different grid path steps exist in PMDO.

Example	Variation	Description
image	Beetle	One large room is generated in the middle. Then, other rooms are generated connecting to this large room.
image	Branch	The rooms and hallways are spawned in a continuous path, which is calculated by the minimum spanning tree algorithm.
image	Circle	A ring of rooms is generated on the outer cells of the grid.
image	Cross	One center room with hallways and rooms coming off of it in the four cardinal directions (north, south, west, east) is generated.
image	Edge	All rooms are placed on one side of the map.
image	Grid	A perimeter of rooms is formed on the outside cells, while hallways are formed inside the cells.
image	Pyramid	A very specific path step. It places a giant room in the center of the floor and a connecting room below it. From that connecting room, it behaves like Grid. It is recommended to not use this step, as it is complex and will likely be broken down into separate generators in the future.
image	Tiered	The floor is generated in tiers of different rooms. Then, a random value of hallways connect each tier together.
image	Treads	Two large "treads" of rooms are generated on the sides of the grid, with smaller rooms and hallways generating in between them.
image	Two Sides	A path consisting of rooms on the far right and far left of the grid are generated.

Spread

Multiple variations may use a spread version, which prioritizes spreading rooms throughout cells rather than generating them together.

Specific

This populates a room by creating a specific path of rooms. It is editor unfriendly.
