Constructor Summary

Agent(java.util.Random gen, Arena a)
Constructs an Agent placed randomly inside the Arena.

Agent(java.util.Random gen, Arena a, java.lang.String name)
Constructs an Agent placed randomly inside the Arena with the name name.

Method Summary

void	clear(java.awt.Graphics2D g) Clear the drawing of the agent at the current coordinates.
void	clear(java.awt.Graphics2D g, java.awt.geom.Point2D c) Clear the drawing of the agent at the indicated coordinates (Basically, a white circle is drawn)
Arena	getArena() Returns a pointer to the Arena where the Agent is placed.
ClassifierSet	getBehaviour() For compatibility reasons, subclasses might implement an Agent whose behaviour is described by a ClassifierSet.
ClassifierSet	getBehaviour(int i) Get the classifier set representing the behaviour of the Agent.
java.awt.geom.Point2D	getCoordNearTo(Entity otherEntity) Return the closest point of the Agent to another Entity
double	getRadius() Get the radius of the agent (which is a circle).
boolean	isDangerous() By default, an Agent is not dangerous.
boolean	isMoving() By default, an Agent is a moving entity.
void	move() Move the agent randomly.
void	move(Arena a, Entity[] others, int nbagents, java.awt.Graphics2D g) Move the Agent by modifying its coordinates.
void	paint(java.awt.Graphics2D g) Remove the drawing of the agent for the old coordinates and repaint the agent at its new coordinates (This avoids a blinking effect)
java.lang.String	toString() Creates a String describing the Agent

Field Detail

heading

protected double heading

Angle which determines where the agent is heading

arena

protected Arena arena

Link to the Arena where the agent is placed.

oldcoord

protected java.awt.geom.Point2D oldcoord

Old coordinates (of the previous position). Used to avoid the blinking effect while the Agent is moving.

Constructor Detail

Agent

public Agent(java.util.Random gen,
             Arena a)

Constructs an Agent placed randomly inside the Arena.

Parameters:

gen - The generator for the random numbers

a - the Arena where to put the agent

See Also:

Arena.isInside(double, double, double)

Agent

public Agent(java.util.Random gen,
             Arena a,
             java.lang.String name)

Constructs an Agent placed randomly inside the Arena with the name name.

Parameters:

gen -

name -

Method Detail

getRadius

public double getRadius()

Get the radius of the agent (which is a circle).

Returns:

the radius (size/2)

See Also:

Entity.size

paint

public void paint(java.awt.Graphics2D g)

Remove the drawing of the agent for the old coordinates and repaint the agent at its new coordinates (This avoids a blinking effect)

Overrides:

paint in class Entity

See Also:

Entity#paint()

clear

public void clear(java.awt.Graphics2D g,
                  java.awt.geom.Point2D c)

Clear the drawing of the agent at the indicated coordinates (Basically, a white circle is drawn)

Overrides:

clear in class Entity

Parameters:

g - Graphics

c - The coordinates where to clear the drawing of the agent.

clear

public void clear(java.awt.Graphics2D g)

Clear the drawing of the agent at the current coordinates.

Parameters:

g - Graphics

See Also:

clear(Graphics2D, Point2D)

move

public void move()

Move the agent randomly. As an example, here the agent moves randomly (on the left or the right + up or down)

move

public void move(Arena a,
                 Entity[] others,
                 int nbagents,
                 java.awt.Graphics2D g)

Move the Agent by modifying its coordinates.

Specified by:

move in class Entity

Parameters:

a - The Arena inside which to move

g - Graphics

See Also:

Entity.move(Arena, Entity[], int, Graphics2D)

getArena

public Arena getArena()

Returns a pointer to the Arena where the Agent is placed.

Returns:

The arena

isDangerous

public boolean isDangerous()

By default, an Agent is not dangerous. Subclasses might be Dangerous and therfore should override this function.

Specified by:

isDangerous in class Entity

Returns:

isMoving

public boolean isMoving()

By default, an Agent is a moving entity.

Specified by:

isMoving in class Entity

Returns:

true

getBehaviour

public ClassifierSet getBehaviour()

For compatibility reasons, subclasses might implement an Agent whose behaviour is described by a ClassifierSet.

Returns:

null for this class (should be overriden by subclasses)

See Also:

AgentClassifier.behaviour, ClassifierSet

getBehaviour

public ClassifierSet getBehaviour(int i)

Get the classifier set representing the behaviour of the Agent.

Parameters:

i -

Returns:

getCoordNearTo

public java.awt.geom.Point2D getCoordNearTo(Entity otherEntity)

Return the closest point of the Agent to another Entity

Overrides:

getCoordNearTo in class Entity

See Also:

Entity.getCoordNearTo(Entity)

toString

public java.lang.String toString()

Creates a String describing the Agent

Overrides:

toString in class Entity
