Detailed Description

A refinement of paths for use when calculating vision.

Constructor & Destructor Documentation

◆ vision_path() [1/2]

pathfind::vision_path::vision_path	(	const unit &	viewer,
		const map_location &	loc,
		const std::map< map_location, int > &	jamming_map
	)

Constructs a list of vision paths for a unit.

This is used to construct a list of hexes that the indicated unit can see. It differs from pathfinding in that it will only ever go out one turn, and that it will also collect a set of border hexes (the "one hex beyond" movement to which vision extends).

Parameters

viewer	The unit doing the viewing.
loc	The location from which the viewing occurs (does not have to be the unit's location).
jamming_map	The relevant "jamming" of the costs being used.

◆ vision_path() [2/2]

pathfind::vision_path::vision_path	(	const movetype::terrain_costs &	view_costs,
		bool	slowed,
		int	sight_range,
		const map_location &	loc,
		const std::map< map_location, int > &	jamming_map
	)

Constructs a list of vision paths for a unit.

This constructor is provided so that only the relevant portion of a unit's data is required to construct the vision paths.

Parameters

view_costs	The vision costs of the unit doing the viewing.
slowed	Whether or not the unit is slowed.
sight_range	The vision() of the unit.
loc	The location from which the viewing occurs (does not have to be the unit's location).
jamming_map	The relevant "jamming" of the costs being used.

◆ edges

std::set<map_location> pathfind::vision_path::edges

The edges are the non-destination hexes bordering the destinations.
