Hi all, I'm very new to programming. Ive got a simple sketch here that uses an array of "Robots" and those robots do "Poo"s on the canvas at their location. The problem is I am adding new Poos to the location of only 1 Robot. I can't think of the solution... any help would be appreciated... im pretty sure its a simple fix, I think the issue is in the Poo class.

Cheers!
2. Robot[] army = new Robot[4];
3. ArrayList <Poo> poops = new ArrayList();
4. int time;
5. int wait = 1000;
7. void setup () {
8. size(400, 400);
9. time = millis();
11. for (int i = 0; i < army.length; i++)
12. {
13. army[i] = new Robot();
14. }
16. poops.add(new Poo(0,0));
17. }
19. void draw () {
21. background(255);
23. for (int i = 0; i < army.length; i++) {
24. army[i].display();
25. }
27. if (millis() - time >= wait) {
29. println(poops.size());
30. for (int i = 0; i < army.length; i++) {
31. army[i].move();
32. army[i].pooper();
34. }
35. time = millis();
36. }
38. stroke (140);
39. for (int i = 1; i < poops.size(); i++) {
40. poops.get(i).display();
41. line(poops.get(i).x, poops.get(i).y, poops.get(i-1).x, poops.get(i-1).y);
42. }
43. }
47. class Robot {
49. float x = (width/2);
50. float y = (height/2);
51. float r = 14;
53. Robot () {
54. }
55. void move () {
57. x = x + random(-50, 50);
58. y = y + random(-50, 50);
60. if (x > width) { x = width;}
61. if (x < 0) { x = 0;}
62. if (y > height) { y = height;}
63. if (y < 0) {y = 0;}
64. }
66. void display () {
67. fill(150);
68. ellipse (x, y, r, r);
69. }
71. void pooper () {
72. poops.add(new Poo(x,y));
73. }
74. }
77. class Poo {
79. float x;
80. float y;
82. Poo (float x_ , float y_ ) {
83. for (int i = 0; i < army.length; i++) {
84. x = army[i].x;
85. y = army[i].y;
86. }
87. }
89. void display() {
90. fill(0);
91. ellipse(x, y, 5, 5);
93. }
94. }
