Problem with geomerative and list

Processing Coding Questions

I have a problem with geomerative and a list of shapes. I think it is trivial, but I don’t understand my error.

If I use this sketch I don’t have any problem.

import geomerative.*;

void setup() 
{
  size(800, 400); 
  smooth();
  background(255);
  noFill();
  RG.init(this);
  stroke(0);
  RShape R = RShape.createRectangle(0, 100, 100, 100);

  for (int i = 0; i < 5; i++)
  {
    R.translate(120, 0);
    R.draw();
  }
}


void draw() {
}

I obtain the right result
If I use a list with this code, I see only the last item of the list:

import geomerative.*;
ArrayList<RShape> shapeList = new ArrayList<RShape>();

void setup() 
{
  size(800, 400); 
  smooth();
  background(255);
  noFill();
  RG.init(this);
  stroke(0);
  RShape R = RShape.createRectangle(0, 100, 100, 100);

  for (int i = 0; i < 5; i++)
  {
    R.translate(120, 0);
    shapeList.add(R);
  }

  for (int i=0; i<shapeList.size(); i++) {
    shapeList.get(i).draw();
  }
}


void draw() {
}

The two results.

Where is the problem?

the issue is that you don’t change the positions. What you are currently doing is stacking them on top of eachother
the R.translate(120,0) doesn’t work this way.
In the for loop just do

for8int i = 0; i < 5; i++) {
   shapeList.add(RShape.createRectangle(i*50,100,100,100));
}

(I am not shore about the syntax for geomerative library

I change the position. I translate every time the position with the R.translate(120,0).

it doesn’t work that way : P

OK thanks! I have to try an another way
