hi there :)

I'm trying to draw a line separate when some keys pressed...

I'm not using line(mouseX, mouseY, pmouseX, pmouseY)

because I want to change the code that can be used with kinect, 3D.

There is a code.

I want to make

if DOWN arrow pressed, a line ends and mouse cursor moves without drawing a line,

if UP arrow pressed, a second line starts to be drawn (separate from the first line)

any idea? TAT

It is driving me crazy plz help !!!!!!!
2. class Line {
3. ArrayList<PVector> polyline = new ArrayList<PVector>();
4. PVector origin;
6. Line() {
7. origin = new PVector(mouseX, mouseY);
8. }
10. void update() {
11. polyline.add(new PVector(mouseX, mouseY));
12. }
14. void display() {
15. noFill();
16. strokeJoin(ROUND);
17. stroke(0,0,255, 100);
18. strokeWeight(10);
20. beginShape();
21. for(PVector p : polyline){
22. vertex(p.x, p.y);
23. }
24. endShape();
25. }
27. }
29. Line l;
31. void setup() {
32. size(400, 400);
33. smooth();
34. l = new Line ();
35. }
37. void draw() {
38. background(0);
39. l.update();
40. l.display();
41. }

Hi, I'm quite a newbie learning Processing for months.

I've seen "kinect graffiti"

http://www.creativeapplications.net/processing/kinect-graffiti-tool-processing-kinect/

it was really fascinating to me so I wanted to make this one by myself..

but I have no idea how to start :(

Is there anyone who tried to do same thing with me before ? or I really appreciate just some advice or sample codes, please... :-)

Have a good day, thanks!
