I'm kinda stuck with my three dimensional implementation of the
game of life. I get very confusing results when trying to figure out the neighbors of each cell. They all end up with a different number of neighbors and none of them has all expected 26. The part in question is the knock() method inside the Cell class. Here's my code so far:
import processing.opengl.*;
boolean pressed = false;
Cell cells[][][];
int dim = 6, space = 25; //dimension of the cube and spacing between the cells
void setup() {
size(600, 600, OPENGL);
background(200, 100, 0);
smooth();
frameRate(24);
text("created by ChristianGeick 2011", width-200, height-50);
cells = new Cell[dim][dim][dim];
for(int x=0; x<dim; x++) {
for(int y=0; y<dim; y++) {
for(int z=0; z<dim; z++) {
cells[x][y][z] = new Cell(x, y, z);
}
}
}
}
void mousePressed() {
pressed = true;
}
void draw() {
if(pressed) {
background(54, 63, 69);
translate(width/2, height/2);
rotateY(radians(frameCount));
for(int x=0; x<dim; x++) {
for(int y=0; y<dim; y++) {
for(int z=0; z<dim; z++) {
if(cells[x][y][z] != null) {
cells[x][y][z].live();
cells[x][y][z].paint();
}
}
}
}
}
}
class Cell {
PVector loc;
int x, y, z;
boolean alive;
Cell neighbors[];
Cell(int a, int b, int c) {
x = a;
y = b;
z = c;
loc = new PVector((x-dim/2)*space, (y-dim/2)*space, (z-dim/2)*space);
if(random(1)>0.5) {
alive = true;
} else {
alive = false;
}
neighbors = new Cell[27];
knock();
}
//!! this is the part that doesn't seem to work properly !!
//get all the 26 neighbors
void knock() {
int count = 0;
int xx, yy, zz; //variables for declaring the neighbor
for(int a=-1; a<=1; a++) {
for(int b=-1; b<=1; b++) {
for(int c=-1; c<=1; c++) {
if(!(a==0 && b==0 && c==0)) { // leave out the actual cell itself
xx = x+a;
yy = y+b;
zz = z+c;
//cells at the edges reach over to the other side of the grid
