Class tjhCreature

java.lang.Object
  |
  +--tjhCreature

public class tjhCreature

extends java.lang.Object

A creature in our psuedo-biological simulation consists of a tree structure of tjhCell's. Also, the creature has a separate genome representation that is copied when it reproduces. Otherwise, evolution would follow the Lamarkian model which ain't no good.

Field Summary

protected tjhGene	genome the tree of tjhGene's that form the creature's genome
boolean	has_died the applet class CellLife uses this to check if this creature died since it last looked
protected tjh2dVector	momentum the current momentum (direction and speed) of the creature
protected boolean	pink_bounce set to true if a pink bounce just occurred
protected tjhCell	root_cell the tree of tjhCell's that form the creature's body
protected static float	SPEED maximum speed of the creature

Constructor Summary

tjhCreature()
default constructor

Method Summary

boolean	DoTimeStep(java.awt.Graphics g, tjhBuckets buckets, tjh2dVector limit) main function that is called for the creature each time step in the simulation.
void	Draw(java.awt.Graphics g) draw the creature
void	InheritFrom(tjhCreature other, tjhBuckets buckets, tjh2dVector limit) this is a new creature, instantiate it from the genes of another (parent) creature
boolean	InitSimple(tjh2dVector limit, tjhBuckets buckets) initialize a simple creature from scratch

Field Detail

SPEED

protected static final float SPEED

maximum speed of the creature

has_died

public boolean has_died

the applet class CellLife uses this to check if this creature died since it last looked

momentum

protected tjh2dVector momentum

the current momentum (direction and speed) of the creature

root_cell

protected tjhCell root_cell

the tree of tjhCell's that form the creature's body

genome

protected tjhGene genome

the tree of tjhGene's that form the creature's genome

pink_bounce

protected boolean pink_bounce

set to true if a pink bounce just occurred

Constructor Detail

tjhCreature

public tjhCreature()

default constructor

Method Detail

DoTimeStep

public boolean DoTimeStep(java.awt.Graphics g,
                          tjhBuckets buckets,
                          tjh2dVector limit)

main function that is called for the creature each time step in the simulation. The creature moves itself and also waves its arms about either randomly or under their own control, depending on whether the neurons are activated. Returns true if it bounced off another creature's pink bit (casual sex!)

InheritFrom

public void InheritFrom(tjhCreature other,
                        tjhBuckets buckets,
                        tjh2dVector limit)

this is a new creature, instantiate it from the genes of another (parent) creature

InitSimple

public boolean InitSimple(tjh2dVector limit,
                          tjhBuckets buckets)

initialize a simple creature from scratch

Draw

public void Draw(java.awt.Graphics g)

draw the creature
