I would like to create a text area for showing the output of the program, something like the console window. I dont want the previous text to be replaced, so the next output will be on the new line. Is there a way to create this? All the text area that I found cant be append.

thank you.

I just started using Kinect with Processing. I am trying to do a simple hand tracking. 

But there is strange thing happened, this is the code:

2. int prevPos = 1;
3. int count = 0;
4. 
   
5. void draw() {
6.   kinect.update();
7.   image(kinect.depthImage(), 0, 0);
8. 
   
9.   for (int i = 1; i < handPositions.size(); i++) { 
10.     currentHand = handPositions.get(i);
11.     previousHand = handPositions.get(i-1);
12.     if (currentHand.x <= 290) { //left area
14.        if (prevPos != 1) {
15.           prevPos = 1;
16.           text(count++, 10, 50);
17.        }
18.     }
19.     else if (currentHand.x > 290 && currentHand.x <= 390) {//middle area
20.       if (prevPos != 2) {
21.         prevPos = 2;
22.       }
23.     }
24.     else {
25.       if (prevPos != 3) {//right area
26.         prevPos = 3;
27.       }
28.     }
29.     line(previousHand.x, previousHand.y, currentHand.x, currentHand.y);
30.   }
31. }

I have simplified the code just to the problem that I encountered. 

Basically I divide the area into 3 parts, according to the hand x-coordinate.

Then, if the hand are still in the same area, I don't want to repeatedly execute the same instruction, in this case is the count++. 

But once it executed, it keep increasing, no matter where the hand is. It seems like even though the prevPos is equal to 1 it still execute the count++.

I would really appreciate if anyone can help me. I am sorry if it turns out a simple mistake, I am not an expert in Processing or programming in general.
