road

A road: a smooth spline through control points, of a road TYPE (lanes, shoulders, curbs, sidewalks, markings, lamps and signs). Every road in the scene is one network: intersections, bridges, cut-and-fill on the land and the lane graph that traffic drives are built from these automatically (build_road / rebuild_roads).

In scene text

road { profile "…"  points [1, 2]  lanes 1 }

Add it in the Inspector (Add Component), in scene text as above, or ask your AI. Fields you leave out keep their defaults.

Fields 19

Field	Type	Unit / range	What it does
`profile`	text	—	.
`points`	list of numbers	m	Control points x, y, z (world), three numbers per point: (x1, y1, z1, x2, y2, z2, ...).
`lanes`	number	0 … 8	Lanes each way (one-way: in total); 0 = the type's own.
`lane_width`	number	m, 0 … 12	Lane width; 0 = the type's own.
`speed_limit`	number	km/h, 0 … 400	Traffic speed; 0 = the type's own.
`one_way`	true / false	—	Every lane runs the way the points run.
`follow_ground`	true / false	—	Heights from the land (smoothed to a drivable grade); off: the points' own heights (ramps, flyovers).
`bridge`	text	—	auto (over water and deep valleys), never (embankment) or always (deck on piers).
`closed`	true / false	—	The last point joins the first (race tracks, ring roads).
`markings`	true / false	—	Lane lines, edge lines, crosswalks and stop lines.
`props`	true / false	—	Street lamps, signs and guard rails by the type's rules.
`control`	text	—	Its intersections: auto, signals, stop, yield or none.
`surface`	text	—	Pavement material; empty = the type's own.
`bank`	number	deg, -1 … 30	Banking into curves; 0 flat, -1 automatic for its speed.
`roots`	number	0 … 10	Trails: roots crossing it per 10 m.
`pebbles`	number	0 … 3	Trails: pebbles along it, 0 none ... 1 a few per metre.
`bulbs`	number	m, 0 … 200	Kerb bulb-outs every this many metres along its parking lanes (0 none): a raised kerbed planter one parking stall long where street dressing puts its trees (clear of the buildings' balconies) and parks no car.
`pier_free`	list of numbers	m	Bridge spans with no piers, as pairs of distances along the road (from, to): a main span hung from its pylons.
`absolute`	list of numbers	m	Spans whose deck follows the control points' own heights (world metres) instead of the land, as pairs of distances along the road (from, to): a main span between pylons on cliffs. Points outside the spans keep their lifts.
