All Known Implementing Classes:

VectorGoal

public interface AStarGoal<T extends AStarNode>

Method Summary

Modifier and Type	Method and Description
float	g(T from, T to) Returns the cost of moving between the two supplied AStarNodes.
float	getInitialCost(T node) Returns the initial cost value when starting from the supplied AStarNode.
float	h(T from) Returns the estimated heuristic cost of traversing from the supplied AStarNode to the goal.
boolean	isFinished(T node) Returns whether the supplied AStarNode represents the goal state for this AStarGoal.

Method Detail

g

float g(T from,
        T to)

Returns the cost of moving between the two supplied AStarNodes.

Parameters:

from - The node to start from

to - The end node

Returns:

The cost

getInitialCost

float getInitialCost(T node)

Returns the initial cost value when starting from the supplied AStarNode. This represents an initial estimate for reaching the goal state from the start node.

Parameters:

node - The start node

Returns:

The initial cost

h

float h(T from)

Returns the estimated heuristic cost of traversing from the supplied AStarNode to the goal.

Parameters:

from - The start node

Returns:

The heuristic cost

isFinished

boolean isFinished(T node)

Returns whether the supplied AStarNode represents the goal state for this AStarGoal. This will halt execution of the calling AStarMachine.

Parameters:

node - The node to check

Returns:

Whether the node is the goal state
