Struct RoadNetwork 

pub struct RoadNetwork {
    pub road_cost_slope: f32,
}

Connects settlements with A* paths that prefer flat terrain.

Fields

road_cost_slope: f32

Implementations

impl RoadNetwork

pub fn new(road_cost_slope: f32) -> Self

pub fn find_path( &self, map: &WorldMap, ax: usize, ay: usize, bx: usize, by: usize, ) -> Vec<(usize, usize)>

Find a road path from (ax,ay) to (bx,by) using A*. Returns list of positions or empty if no path found.

pub fn shortest_trade_route( &self, map: &WorldMap, settlements: &[Settlement], a_id: u32, b_id: u32, ) -> Vec<(usize, usize)>

Shortest trade route between two settlements (by name lookup).

pub fn build_roads( &self, map: &mut WorldMap, settlements: &[Settlement], rng: &mut Rng, )

Connect all settlements with roads; mark road cells on the map.

Trait Implementations
