triangle

as my second project in processing, i was trying to implement langton's ant algorithm. however, when i ran my code it produced a right triangle which grows each iteration.
unintentional, but i thought it was kinda nifty. nothing too spectacular.
Code:int x = 100;
int y = 100;
int dir = 90;
color on;
color off;
void setup () {
size(200, 200);
colorMode(RGB);
noBackground();
on = color(0, 0, 0);
off = color(255, 255, 255);
}
void loop() {
color c = getPixel(x, y);
if (c == on) {
setPixel(x, y, off);
} else {
setPixel(x, y, on);
}
if (dir == 0) { y = max(y - 1, 0); }
if (dir == 90) { x = min(x + 1, width); }
if (dir == 180) { y = min(y + 1, height); }
if (dir == 270) { x = max(x - 1, 0); }
c = getPixel(x, y);
if (c == off) {
dir = (dir + 90) % 360;
} else {
dir = (dir - 90) % 360;
}
} |

if anyone sees why it doesn't work as intended, please point it out. thanks!
