Paths that lead somewhere

Dream docs / Paths and destinations

A painted rectangle is ground color. A path also needs a connection, clearance and somewhere to go. surface(...,walkable=true) makes that distinction explicit. The same pavement supports ambient walkers and existing work journeys. It adds no actor, controller, traffic rule or road grip.

Join convex strips into a loop, connect an entrance to the sidewalk and leave the whole path clear. Keep benches, lamps, planting and vehicle parking beside it. The compiler rejects isolated pieces, point-only corners, obstructions and rail or runway overlaps. Water needs a real supporting bridge; paths enter through its open ends and fit between its rails. The existing 64-surface, 8192-node and 192-ambient-member limits still apply.

site.label names a place without renaming its shared asset. It is optional, plain text, 1–80 nonblank characters. A reused post or bench can mark a named park; it does not become a new behavior. The minimap uses P for declared parks.

A complete pocket park

The post has an attached entrance, and four strips form a continuous walking loop. Standard paving #bcb6a4 merges with entrance paths, so a path is not painted twice. finish=terrain may also declare a walkable natural path without adding a mesh.

The live Garden park

The garden neighborhood has two sidewalk entrances, six benches, three parked bicycles and three scooters, eight walking visitors, shade trees and low planting. Press F to sit or stand, or to board a nearby ride. All ten benches across the city use the same sitting and splinter rules. The existing caretaker can repair the six new benches and four lamps using finite kits, wages and actual walking journeys. The five new trees retain their category behavior; this furniture service does not imply city-wide replanting.
