I have a project due in a few days---and I just started today.. it's not the hardest thing in the world, but I always have a hard time figuring out how to move existing code into a class successfully.

this is what I have so far, It's a modified version of Example 15-14 "Pointillism"

----------------------------------------------------------------------------------------------------------------------------------

PImage purpleBrain;

Brain bb;

float pointillize = 16;

void setup() {

size(430, 550);

purpleBrain=loadImage("purple MRI.jpg");

bb = new Brain();

smooth();

}

void draw() {

background(0);

bb.pointillize();

bb.display();

}

class Brain {

int x;

int y;

int loc;

float r;

float g;

float b;

Brain() {

//purple---------

x = int(random(purpleBrain.width));

y = int(random(purpleBrain.height));

loc= x + y*purpleBrain.width;

}

void pointillize() {

loadPixels();

float r = red(purpleBrain.pixels[loc]);

float g = green(purpleBrain.pixels[loc]);

float b = blue(purpleBrain.pixels[loc]);

}

void display () {

noStroke();

fill(r, g, b, 100);

ellipse(x, y, pointillize, pointillize);

}

}

--------------------------------------------------------------------------------------------------------------

it just shows up black when I run it.

Thanks to anyone who can help!
