RoadGraphType

RoadGraphType holds the kinds of routes in the game's road graph (the network of roads, sea lanes, flight paths, footpaths and railways the AI travels on). Use it to ask the road graph for one kind of route only, and to tell what kind a returned route is.

Available on: Client

Values

RoadGraphType

The values are bit flags: combine several to accept several kinds at once with bit.bor or by adding them, and test a flag with bit.band (see Sandbox). Each edge has exactly one kind, so compare a returned type with ==.

Used by (see RoadGraph):

• RoadGraph.GetSamples(position, radius, types): types (optional, default RoadGraphType.Any) limits the samples to edges of those kinds. Each sample's type field is the kind of its edge.
• RoadGraph.GetEdge(id): the returned table's type field is the kind of that edge.

Name	Value	Meaning
RoadGraphType.Land	2	Roads for land vehicles.
RoadGraphType.Sea	4	Routes for boats.
RoadGraphType.Air	8	Routes for aircraft.
RoadGraphType.Pedestrian	16	Paths for people on foot.
RoadGraphType.Railway	32	Railways.
RoadGraphType.Any	62	Every kind above combined.

Example

-- client: find road or railway points within 200 m of the local player
Cmd.Add("roads", function()
	local player = World.LocalPlayer()
	if not player then
		return
	end

	local types = RoadGraphType.Land + RoadGraphType.Railway
	local samples = RoadGraph.GetSamples(player:GetPosition(), 200, types)

	for _, sample in ipairs(samples) do
		local kind = sample.type == RoadGraphType.Railway and "railway" or "road"
		print(string.format("%s at %.0f %.0f %.0f (edge %d)", kind, sample.position.x, sample.position.y, sample.position.z, sample.edge))
	end
