hi there!!!
i am very new in programing and i do not know how to move from hard code to a simple way.
or maybe i need to use an array.
attach code
int numCircles = 27;
int [][] circles; // use a two-dimensional array
PrintWriter output;
PImage b;
int value = 0;
void setup () {
// Create a new file in the sketch directory
output = createWriter("positions.txt");
size(512, 350);
smooth();
noStroke();
b = loadImage("manikin.jpg");
imageMode(CENTER);
image(b, width/2, height/2, width, height);
circles = new int [numCircles][3]; // define the array, every circle needs three parameters (xPos, yPos, circleDiameter)
// fill array only once
for (int i=0; i<numCircles; i++) {
int circleDiameter = int(20);
int xPos = int(109); // keep distance from border
int yPos = int(67); // keep distance from border
circles[i][0]= xPos + (i % 9) * 38; //horizontal position
circles[i][1]= yPos + (i / 9) * 135;//vertical position
circles[i][2]= circleDiameter;
}
}
void draw() {
for (int i=0; i<numCircles; i++) {
fill(value);
ellipse(circles[i][0], circles[i][1], circles[i][2],circles[i][2]);
}
}
