init

add

think

public void think(Commandable agent)

setNearestVisible

public void setNearestVisible(Commandable monster,
                              Commandable[] targets,
                              java.lang.String name)

Given a set of creatures, find the nearest one we have a clear LOS to. Record it on the agent.

Parameters:

targets - the non-null, nonempty set of nearby targets

name - the name to use for the properties

setNearestReachable

public void setNearestReachable(Commandable agent,
                                Commandable[] targets,
                                java.lang.String name)

Given a set of creatures, find the nearest one we can reach. Record it on the agent.

Parameters:

agent - the monster

targets - the non-null, nonempty set of nearby targets

name - the name to use for the properties

getNearbyTargets

public Commandable[] getNearbyTargets(Commandable agent,
                                      Predicate hatesThesePlayers,
                                      Predicate hatesTheseMonsters,
                                      java.util.Set hates)

Returns a list of nearby targets close enough to chase and matching the appropriate predicate. Side effect: sets a property on the agent called "@a*-rect" containing the rectangle centered around the monster that it's willing to search. The internal names assume that it's looking for enemies, but it works for finding anything that matches a predicate.

Parameters:

agent - the monster

Returns:

a list of nearby targets, or null if none were found

targetAdjacentMonster

protected Point targetAdjacentMonster(Commandable monster,
                                      Commandable target)

Looks for a player to target. Works via side-effect: if we find a player adjacent to us, remembers the player (as a property) so we can fire in that direction later.

Parameters:

monster - the monster

target - the target player/monster

Returns:

a point to fire at if the target is adjacent

getDistance

public int getDistance(Point p1,
                       Point p2)
