Constructor Summary

Agent(int x, int y, ModelDisplay modelDisplayer, Simulation thisSim)
Constructor that takes the x and y and a model display to draw it on

Agent(ModelDisplay modelDisplayer, Simulation thisSim)
Constructor that takes the model display (the original position will be randomly assigned)

Constructor Detail

Agent

public Agent(ModelDisplay modelDisplayer,
             Simulation thisSim)

Constructor that takes the model display (the original position will be randomly assigned)

Parameters:

modelDisplayer - thing that displays the model

thisSim - my simulation

Agent

public Agent(int x,
             int y,
             ModelDisplay modelDisplayer,
             Simulation thisSim)

Constructor that takes the x and y and a model display to draw it on

Parameters:

x - the starting x position

y - the starting y position

modelDisplayer - the thing that displays the model

thisSim - my simulation

Method Detail

setSpeed

public void setSpeed(int velocity)

Accessors

getSpeed

public int getSpeed()

getSimulation

public Simulation getSimulation()

init

public void init(Simulation thisSim)

Method to initialize the new wolf object

die

public void die()

Method that handles when an Agent dies

getClosest

public Agent getClosest(double distance,
                        LinkedList list)

Method to get the closest agent within the passed distance to this agent but NOT this agent. We'll search the input list of the kind of objects to compare to.

Parameters:

distance - the distance to look within

list - the list of agents to look at

Returns:

the closest agent in the given distance or null

countInRange

public int countInRange(double range,
                        LinkedList list)

Method to count the number of agents within the range that are on the given list

Parameters:

range - the number of steps within which to consider agents

list - of agents to consider

Returns:

the number of agents within range.

act

public void act(int t)

act() with a timestep

act

public void act()

Method to act during a time step Default is to pick a random direction and move some random amount up to top speed
