Hi

I wanna make this very simple drawing tool without using mouseX, pmouseX, etc... 
But how can i get an interruption when i stop drawing and than start again.
For example the array is at a value of 12 when i stop dragging the mouse, when i press again it should skip
number 13 in the array.
Do i need a return or a break funktion?

1. int[] x = new int[0];
2. int[] y = new int[0];
3. int mx,my;
4. boolean drag = false;
5. void setup() {
6.   size(600, 600);
7. }
8. void draw() {
9.   background(255);
10.   rectMode(CENTER);
11.   noFill();
12.   mx = mouseX;
13.   my = mouseY;
14.   beginShape();
15.   for (int i = 0; i < x.length-1; i+=1) {
16.     line(x[i+1], y[i+1],x[i], y[i]);
17.   } 
18.   endShape();
19.  
20.   if(drag){
21.     x = append(x, mx);
22.     y = append(y, my);
23.   }
24. }
25. void mousePressed(){
26.   drag = true;
27. }
28. void mouseReleased(){
29.   drag = false;
30. }

thanks!
