public PointsOfInterest(SimMap parentMap,
                        int[] okMapNodeTypes,
                        Settings settings,
                        java.util.Random rng)

Constructor.

Parameters:

parentMap - The map whose MapNodes' subset the POIs are

okMapNodeTypes - Array of map node types that are OK to visit or null if all nodes are OK

settings - The Settings object where settings are read from

rng - The random number generator to use

Method Detail

selectDestination

public MapNode selectDestination()

Selects a random destination from POIs or all MapNodes. Selecting among POI groups is done by their probabilities. If sum of their probabilities is less than 1.0 and the drawn random probability is bigger than the sum, a random MapNode is selected from the SimMap.

Returns:

A destination among POIs or all MapNodes
