Constructor Detail

BirdAgent

public BirdAgent(ModelDisplay modelDisplayer,
                 Simulation thisSim)

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

Parameters:

modelDisplayer - thing that displays the model

thisSim - my simulation

BirdAgent

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

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

Parameters:

x - the starting x position

y - the starting y position

modelDisplayer - the thing that displays the model

thisSim - my simulation

Method Detail

init

public void init(Simulation thisSim)

Set up the birds

Overrides:

init in class Agent

Parameters:

thisSim - the simulation to use

act

public void act(int t)

act(t) For first 20 steps, walk toward the egg, +/- 30 degrees. Then walk AWAY from the egg, and with MORE wandering (panic).

Overrides:

act in class Agent

Parameters:

t - the timestep
