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, clone your project. The Arrays of Objects worksheet might be helpful. NOTE: you must use Math.random() for all the random numbers in this assignment.
- A class to represent a single bacteria or some other single organism. The class will have the following members:
- At least 3 ints which hold the x and y coordinates of the bacteria position, and the bacteria color.
- A constructor which initializes the 3 ints
void move()which moves the bacteria in a random walk pattern.- Rember, when you implement move you are ONLY doing this for the one instance.(implement is just the coders way of saying write the method)
void show()which draws the bacteria using the three member variables- For some of you these requirements will be completed quickly, so I am looking for you to push yourself and try to complete something out of extras.
- You will then use an array to store many instances of the Bacteria.
- Personalize the title, headline and footer of
index.html - Your simulation doesn't have to look like any other. Have fun and be creative.
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.
-
dist(x1, y1, x2, y2 ) - reports the distance between two points
- eg) dist(0,0, 3,4 ); //The distance from the origin to the point 3,4
-
mousePressed, is a boolean available in processing. true/false
-
mouseX, mouseY - reports the current coordinates of the mouse position
- Note, if the mouse is beyond the canvas it simply reports the mouseX/mouseY position last seen
- unless you click on the canvas and drag to off the canvas
