Let me know when I can upload another version to show you.
I have some image issues that I am working on.
OK! Got the image problem taken care of!

On fixing 'Infect'
kiarocks, it has been uploaded for you.
Also, it is being looked at to determine why a compiler message is popping up after compiling the program.
Do you want me to take it off? or leave it on? I have no need for it to be on anymore.
I took it off.
Yes, one survived! It was probably hiding under a rock and avoided getting infected!
First, in the Person.class, add the variables 'private int age = 18 * InfectWorld.ageRate;' and 'private int procreateChance = 20;' and 'private int infectChance = 10;' and 'private int deathChance = 5;' and, of course, 'private int sex;'.
In '(World) InfectWorld' you could add another variable 'public static final int ageRate = 20;' to regulate how fast they age. '20' is probably not what you want (it can be changed -- higher, probably, or lower, I doubt). It will be the number of Person.act()s cycled through to complete one year of life.
This would be the basics for setting up what he was referring to.
public void act() // In 'Person.class'
{
age++;
int actualAge = (age - (age % InfectWorld.ageRate) ) / InfectWorld.ageRate; // Computes actual age
if (age % InfectWorld.ageRate == 0 && actualAge % 13 == 0) // On every 13th Birthday
// The first part asks if it is a birthday, the second part asks if actualAge is a multiple of 13
{
infectChance += 10;
deathChance += 5;
}
if (actualAge< 15) { procreateChance = 0; }
if (actualAge > 14) { procreateChance = 10; }
if (actualAge > 20) { procreateChance = 30; }
if (actualAge > 35) { procreateChance = 10; }
if (actualAge > 40) { procreateChange = 5; }
if (actualAge > 50) { procreateChange = 1; }
// This next part adjust the image size for growth
GreenfootImage myImage = getImage(); // full size = 43 x 51
int myWidth = (actualAge + 1) * 43 / 18;
if (myWidth > 43) { myWidth = 43; }
int myHeight = (actualAge + 1) * 51 / 18;
if (myHeight > 51) { myHeight = 51; }
myImage.scale(myWidth, myHeight);
setImage(myImage);
// Check for death
if (Greenfoot.getRandomNumber(100) < deathChance)
{
die(); // Need to create method 'private void die() { ... }' to do what needs done when death occurs
}
... // Check for near infecteds, and if so:
if (Greenfoot.getRandomNumber(100) < infectChance)
{
infect();
}
// Check for couterpart Person adjacent, and if so:
if (Greenfoot.getRandomNumber(100) < procreateChance)
{
procreate(); // add Person: age, procreateChance, infectChance = 0; sex = Greenfoot.getRandomNumber(2); etc.
}
... // other code you MIGHT already have
}Actually, it might be better for lines 5 through 16 above to incorporate the use of a 'switch' like so:
if (age % InfectWorld.ageRate == 0) // asking if is an actual birthday
{
switch (actualAge)
{
case 13:
infectChance = 10;
deathChance = 1;
procreateChance = 2;
break;
case 18:
infectChance = 15;
deathChance = 5;
procreateChance = 10;
break;
case 21:
deathChance = 3;
procreateChance = 15 - 5 * infectionLevel;
break;
case 26:
procreateChance = 20 - 5 * infectionLevel;
case 35:
procreateChance = 5 - infectionLevel;
case 50:
procreateChance = 0;
infectChance = 20;
deathChance = 5;
case 60:
infectChance = 25;
deathChance = 8;
case 75:
infectChance = 30;
deathChance = 12;
}
}You could even add to Person.class the variables 'private boolean isPregnant = false;' and 'private int howLongTillDue = 0;' so if procreating, change 'isPregnant' to 'true' and 'howLongTillDue' to 'InfectWorld.ageRate * 3 / 4' (equivalent to 9 months).
In act() for Person:
And add methods: (find out which of the two encountering Persons is the female)
Add a new constructor:
if (isPregnant)
{
howLongTillDue--;
if (howLongTillDue == 0)
{
getWorld().addObject(new Person(0, 0), getX(), getY());
isPregnant = false;
}
}private void procreate(Person female)
{
isPregnant = true;
howLongTillDue = InfectWorld.ageRate * 3 / 4;
}public void Person(int myAge, int stageOfInfection)
{
age = myAge;
infectionStage = stageOfInfection;
sex = Greenfoot.getRandomNumber(2);
direction = Greenfoot.getRandomNumber(4);
setRotation(90 * direction);
// set image and set other variables here
}Where the other variables for Person are declared:
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
import java.util.*;
public class Person extends Actor
{
private int direction;
private int infectionStage;
private int actCycle = 0;
// Each instance of Person has these variables and the values are independent from each other
// The new variables go right along with those above
private int age;
private int sex;
private int infectChance;
private int procreateChance;
private int deathChance;
private boolean isPregnant = false;
private int howLongTillDue = 0;
public Person()
{
direction = Greenfoot.getRandomNumber(4);
setRotation(90 * direction);
age = Greenfoot.getRandomNumber(100);
sex = Greenfoot.getRandomNumber(2);
infectionStage = 0;
// set other variables and image dependent on age/infectionStage
}
public Person(int myAge, int stageOfInfection)
{
age = myAge;
infectionStage = stageOfInfection;
sex = Greenfoot.getRandomNumber(2);
// set other variables and image
}
public void act()
{
// act code
}
