I was trying to use the Z position of a hand to emulate a button press. So far when I try it using one hand it works really well, however, when I try to get it to work with a second hand, only one of the hands work. (I know it can be more efficient by moving everything except the fill out of the if statements, but I kept those in there just in case I want to change the sizes or something.)

irz and ilz are the initial Z positions of the hands when they are first recognized by onCreateHands and rz and lz are the current Z positions. As of now, the code works fine with one hand, but the other hand will either stay pressed or unpressed. If i comment one of the sections out, it works fine as well.

2. if (rz - irz > 0) {
3.     pushStyle();
4.     fill(60);
5.     ellipse(rx, ry, 10, 10);
6.     popStyle();
7.     rpressed = true;
8.   }
9.   else {
10.     pushStyle();
11.     noFill();
12.     ellipse(rx, ry, 10, 10);
13.     popStyle();
14.     rpressed = false;
15.   }
16.   
17.   if (lz - ilz > 0) {
18.     pushStyle();
19.     fill(60);
20.     ellipse(lx, ly, 10, 10);
21.     popStyle();
22.     lpressed = true;
23.   }
24.   else {
25.     pushStyle();
26.     noFill();
27.     ellipse(lx, ly, 10, 10);
28.     popStyle();
29.     lpressed = false;
30.   }

I tried outputting the values of rz - irz and lz - ilz and the numbers range from small negative values to small positive values (around -8 to 8) for lz - ilz. But rz - irz outputs numbers from around 8-30 depending on each time I run it and is never consistent. Also, when I comment out the code for the lz-ilz, the values for rz-irz look just fine and it operates as intended. Is there a reason tracking both Z positions throws off one hand? And is there a way to get it to work?

Thanks!
