Always amazing to see what sort of playful and visually attractive experience you can spark with just a few lines of code! Starting a series here titled “Fun With Arrays” in Processing.
The code:
int num =150;
int[] x = new int[num];
int[] y = new int[num];
void setup() {
size(600, 400);
noStroke();
fill(255, 102);
}
void draw() {
background(0);
// Shift the values to the right
for (int i = num-1; i > 0; i--) {
x[i] = x[i-1];
y[i] = y[i-1];
}
// Add the new values to the beginning of the array
x[0] = mouseX;
y[0] = mouseY;
// Draw the circles
for (int i = 0; i < num; i++) {
ellipse(x[i], y[i], i/2.0, i/2.0);
}
}
