Chemotaxis

Chemotaxis is when an organism moves toward or away from a chemical stimulus like food. Biologists write software using random walks to model and study how very small organisms like bacteria search for food. In this assignment you will create a simulation of organisms moving away from a starting position using a random walk. To start the assignment, fork this repository. You may find slides 22 - 79 on the OOP--ArraysOfObjects presentation and the Arrays of Objects worksheet helpful. NOTE: you must use Math.random() for all the random numbers in this assignment.

Requirements

1. A class to represent a single bacteria or some other single organism. The class will have the following members:
   • 3 int variabless which hold the x and y coordinates of the bacteria position, and the bacteria color. (See slide 35 on the OOP--ArraysOfObjects presentation for one way to store the bacteria color in an int variable)
   • A constructor which initializes the 3 int variables
   • void move() which moves the bacteria in a random walk pattern.
   • void show() which draws the bacteria using the three member variables
2. You will then use an array to store many instances of the Bacteria.
3. Personalize the title, headline and footer of index.html

Extensions

If you have extra time, you might try to have the bacteria move in a "biased random walk" towards some stimulus like a piece of food or the mouse. You can use the mouse buttons to adjust the bias towards or away from the mouse. You can modify your class so the bacteria have a finite lifespan and can reproduce. You can simulate other organisms besides bacteria and even have multiple types of organisms like a predator and prey. Your simulation doesn't have to look like any other. Have fun and be creative.
