Field Summary

static double	ATTACK_RANGE class constant for how close before wolf can attack
static Color	GRAY 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 wolf can smell

Constructor Summary

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

Wolf(ModelDisplay modelDisplayer, WolfDeerSimulation thisSim)
Constructor that takes the model display (the original position will be randomly 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
AgentNode	getClosest(double distance, AgentNode list) Method to get the closest deer within the passed distance to this wolf.
WolfDeerSimulation	getSimulation() Method to get the simulation
void	init(WolfDeerSimulation thisSim) Method to initialize the new wolf object

Constructor Detail

Wolf

public Wolf(ModelDisplay modelDisplayer,
            WolfDeerSimulation thisSim)

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

Parameters:

modelDisplayer - thing that displays the model

thisSim - my simulation

Wolf

public Wolf(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 - my simulation

Method Detail

getSimulation

public WolfDeerSimulation getSimulation()

Method to get the simulation

Returns:

the simulation

init

public void init(WolfDeerSimulation thisSim)

Method to initialize the new wolf object

Parameters:

thisSim - the simulation

getClosest

public AgentNode getClosest(double distance,
                            AgentNode list)

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