Modifier and Type	Method	Description
protected boolean	discardPath(MovePath path, MovePathFinder.CoordsWithFacing pathDestination)	Worker function to determine whether we should discard the current path (due to it being illegal or redundant) or keep generating child nodes
protected List<MovePath>	generateStartingPaths(MovePath startingEdge)	Generates a list of possible step combinations that should be done at the beginning of a path Has side effect of updating the visited coordinates map and adding it to the list of generated paths
Collection<MovePath>	getAllComputedPathsUncategorized()
static NewtonianAerospacePathFinder	getInstance(Game game)
protected void	initializeMoveList()	Worker method to put together a pre-defined array of possible moves
protected boolean	isIntermediatePath(MovePath path)	"Worker" function to determine whether the path being examined is an intermediate path.
void	run(MovePath startingEdge)	Computes paths to nodes in the graph.

protected NewtonianAerospacePathFinder(Game game)

Method Details

initializeMoveList

protected void initializeMoveList()

Worker method to put together a pre-defined array of possible moves

getAllComputedPathsUncategorized

public Collection<MovePath> getAllComputedPathsUncategorized()

run

public void run(MovePath startingEdge)

Computes paths to nodes in the graph.

Parameters:

startingEdge - the starting node. Should be empty.

getInstance

public static NewtonianAerospacePathFinder getInstance(Game game)

generateStartingPaths

protected List<MovePath> generateStartingPaths(MovePath startingEdge)

Generates a list of possible step combinations that should be done at the beginning of a path Has side effect of updating the visited coordinates map and adding it to the list of generated paths

Returns:

List of all possible "starting" paths

isIntermediatePath

protected boolean isIntermediatePath(MovePath path)

"Worker" function to determine whether the path being examined is an intermediate path. This means that the path, as is, is not a valid path, but its children may be. This mainly applies to aero paths that have not used all their velocity. For newtonian space flight, it is never an intermediate path.

Parameters:

path - The move path to consider.

Returns:

Whether it is an intermediate path or not.

discardPath

protected boolean discardPath(MovePath path,
 MovePathFinder.CoordsWithFacing pathDestination)

Worker function to determine whether we should discard the current path (due to it being illegal or redundant) or keep generating child nodes

Parameters:

path - The move path to consider

Returns:

Whether to keep or dicsard.
