Drawing chains using loops

Processing Coding Questions
1

Am working on a code using loops, basically what I want to do is draw a chain of circles that stretches from the center of the screen to the mouse position. but I can’t make the chain follow the mouse this is my code so far please help anyone

final float TARGET_SPACING = CIRCLE_DIAMETER * 0.75;

//One end of the chain (the "anchor point") will be the centre of the canvas. 
float anchorX, anchorY; //Can't set until after size() is done.
void setup() {
  size(500,500);
  anchorX = width/2;
  anchorY = height/2;
  strokeWeight(2); //It looks better with thicker lines
  stroke(255);     //white lines
  noFill();        //and hollow circles
}//setup

void draw() {
  background(0);
  
  float chainLenght= sqrt(sq(mouseX-anchorX) + sq(mouseY-anchorY));
 
  float totalCircles=(chainLenght/TARGET_SPACING) +1;

  round(totalCircles);
  
  float circleArea = (totalCircles/CIRCLE_DIAMETER);
  float AreaH=(mouseX/TARGET_SPACING);
  float AreaV=(mouseY/TARGET_SPACING);
  float exactCircleArea = sqrt(sq(anchorX + circleArea) + sq(anchorY + circleArea));
  
  
  for(float circle=1; circle<=totalCircles; circle+=circleArea){
    ellipse(anchorX+(circle*AreaH),anchorY+(circle*AreaV),CIRCLE_DIAMETER,CIRCLE_DIAMETER);
  }
  

};

Hey I think what you want to build are Forward Kinematics.
Here is a very good tutorial by Daniel Shiffman:

Am Strictly limited to loops in this situation

So its a homework?
If then pls tag it as one :slight_smile:
