im trying to join the lines manually, however when i duplicate the Spot class to Spot &Spot2 class

it says "the constructor Spot2 is undefined" when i run the script, but when i switch back to use Spot class only, the script run..

please help me thank you.
3. Spot sp,sp2,sp3,sp4,sp5;
4. Spot2 spa,sp2a,sp3a,sp4a,sp5a;

please help me, im new with processing

i have been trying to create a grid with ball class but i don't know why it not working,

i think i got it right..

i think what i did wrong was not calling it out correctly, please help

moreover how can i connect the balls to form a grid?

and how do i prepare the ball class in to 3d realm? because i dont know how..

please help me thank you very much!!

here is my code
2. import peasy.*;
3. PeasyCam cam;
5. // decade class ball is myBall
6. Ball[] balls;
8. int spacing = 10;
12. void setup (){
13. size(600,600,P3D);
14. // noStroke ();
16. // this is for the camera settings
17. cam = new PeasyCam(this,450);
18. cam.rotateX(PI*0.3);
19. cam.rotateZ(PI*0.3);
21. for (int i = spacing; i <height; i+= spacing){
22. balls[i] = new Ball();
23. }
26. }
28. void draw (){
29. background (0);
32. for (int i = spacing; i <height; i+= spacing){
33. for (int j = spacing; j <width; j+= spacing){
34. balls[i].display();
36. }
37. }
38. }
41. class Ball {
42. float x;
43. float y;
44. float z;
45. // float speed;
47. void start (float xpos, float ypos) {
48. x = xpos;
49. y = ypos;
51. // zpos = tempZpos;
53. }
55. void display() {
57. ellipse(x, y, 10, 10);
59. //// drawing the circles up each time the script runs
60. }
61. }

guys im new to processing..so i need ur help!! :)

what i intend to do is to create a grid with ball class, i manage to get it to draw an ellipse, however when i did it with my ball class it does not seem to work.

moreover after the grid by the ball is done, thinking of moving the ball on Z-axis, but i dont know where is that applied, does it have to be included in the ball class? or do i have to do something else

thanks heres my code
2. import peasy.*;
3. PeasyCam cam;
5. // decade class ball is myBall
6. Ball[] balls;
7. //int ballAmount = 125;
8. //int distance = 100;
9. //int space = 30;
10. ////int radius = 15;
12. void setup (){
13. size(600,600,P3D);
14. noStroke ();
16. ////// this is for the camera settings
17. cam = new PeasyCam(this,450);
18. cam.rotateX(PI*0.3);
19. cam.rotateZ(PI*0.3);
22. for (int i = 0; i < balls.length; i++) {
23. balls[i] = new Ball(random(-1,1), random(-1,1));
24. }
26. }
28. void draw (){
29. background (0);
30. int stepsize = 10;
31. for (int i = stepsize; i <height; i+= stepsize){
32. for (int j = stepsize; j <width; j+= stepsize){
33. balls[i]. display();
34. //what i want to draw /add class ball in
35. }
36. }
37. }
38. class Ball {
  
  float xpos;
  
  float ypos;
  
  float zpos;
  
  float speed;
  
  Ball(float tempYpos, float tempZpos) {
  
  //// preping info about the circle ready to be drawn
  
  xpos = int(random(0, 899));
  
  //// x coordinate of the center of the circle randoming number between 0 to the width of screen
  
  ypos = int(random(0, 899));
  
  //// y coordinate of the center of the circle
  
  zpos = int(random(0, 899));
  
  }
  
  void display() {
  
  //// setup for the sketch. ie colors and draw the circle
  
  fill(255);
  
  ellipse(xpos, ypos, 5, 5);
  
  PVector linep = new PVector (xpos,ypos,zpos);
  
  // point(linep.x, linep.y, linep.z);
  
  stroke(255);
  
  strokeWeight(4);
