Detailed Description

Finds a path in a Grid2D using the Breadth First Search algorithm.

Definition at line 38 of file BFS.h.

Constructor & Destructor Documentation

ime::BFS::BFS ( const Vector2u & gridSize )

explicit

Initialize the algorithm.

Parameters

gridSize Size of the grid in tiles

std::stack< Index > ime::IPathFinderStrategy::backtrack	(	const std::vector< Node > &	exploredNodes,
		const Index &	target
	)

protectedinherited

Generate path from the source to the target.

Parameters

exploredNodes	Nodes explored after algorithm termination
target	The index of the target tile in the grid

Returns: The path from the source to the target tile if found, otherwise an empty path

std::stack< Index > ime::BFS::findPath	(	const Grid2D &	grid,
		const Index &	sourceTile,
		const Index &	targetTile
	)

overridevirtual

Generate a path from a source tile to a target tile in a grid.

Parameters

grid	Grid to generate path in
sourceTile	The position of the starting position in tiles
targetTile	The position of the destination in tiles

Returns: The path from the source to the destination if reachable, otherwise an empty path

std::string ime::BFS::getType ( ) const

overridevirtual

Get the type of path finding algorithm.
