Hello there,  

This is my first time here so i would first like to say hi to everyone.
I'm very new with Processing but i find quite powerful and useful.

I'm having a problem with getting a value from a (very simple) custom object i made. It is instantiated inside the draw() method and each object is stored in an arrayList right after instantiation.
Basically i'm just trying to set a class property telling me if the object was clicked or not but when trying to set the property, from the method wasClicked(), i always get x and y coordinates valued to 0... Although the shapes appear on screen.

The final result will be a set of 3D boxes on which there will be a picture textured onto each side.

Here is the full code, any idea is welcome

Cheers

Terence

float x =  70.0;
float y = 35.0;
float z = 120.0;
float Y = 0;
float Z = 0;
	
void mouseDragged() {
  if(mouseButton == LEFT) {
    x = pmouseX;
    y = pmouseY;    
  } 
  if(mouseButton == RIGHT) {
    Y = mouseX/PI;
  }   
}

void mousePressed() {
  for(int cpt = 0; cpt < panels.size(); cpt++) 
  {
    println(((panel)panels.get(i)).width);
//    panel tempPanel = (panel)panels.get(i);
//    if(tempPanel.wasClicked() == true) {

those little things... thank you very much !
