Field Summary

static Color	BROWN class constant for the color
static int	MAX_SPEED class constant for top speed (max num steps can move in a timestep)
static double	PROB_OF_STAY class constant for probability of NOT turning
protected static Random	randNumGen random number generator
static double	SMELL_RANGE class constant for how far deer can smell

Constructor Summary

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

Deer(ModelDisplay modelDisplayer, WolfDeerSimulation thisSim)
Constructor that takes the model display (the original position will be randomally assigned

Method Summary

void	act() Method to act during a time step pick a random direction and move some random amount up to top speed
void	die() Method that handles when a deer dies
AgentNode	getClosest(double distance, AgentNode list) Method to get the closest wolf within the passed distance to this deer.
void	init(WolfDeerSimulation thisSim) Method to initialize the new deer object

Constructor Detail

Deer

public Deer(ModelDisplay modelDisplayer,
            WolfDeerSimulation thisSim)

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

Parameters:

modelDisplayer - thing which will display the model 2param thisSim the simulation

Deer

public Deer(int x,
            int y,
            ModelDisplay modelDisplayer,
            WolfDeerSimulation 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 - the simulation

Method Detail

init

public void init(WolfDeerSimulation thisSim)

Method to initialize the new deer object

Parameters:

thisSim - the simulation to use

getClosest

public AgentNode getClosest(double distance,
                            AgentNode list)

Method to get the closest wolf within the passed distance to this deer. 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

act

public void act()

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

die

public void die()

Method that handles when a deer dies
