I'm creating something that uses Peasy to rotate the camera. The screen has some text that spins around and I need to make each text spot clickable. I have spent a few hours trying to figure this out, but I have no success. Does anyone have any ideas and can help me with this problem?

I know how to make a non-moving rect() clickable using an if-statement with mouseX and mouseY. But I don't know what to do if the rect() is rotating. Any suggestions are welcome. Using other libraries like controlP5 is okay with me too; I really need help getting this to work!

I've uploaded a .zip of the sketch if you want to download it on dropbox, or you can view the code below:

1. import peasy.*;
2. 
   
3. PeasyCam cam;
4. PFont font;
5. 
   
6. PImage pim;
7. float rot=0;
8. 
   
9. ArrayList<String> aList = new ArrayList<String>();
10. 
    
11. void setup(){
12.   size(800, 600, P3D);
13.   //smooth();
14.   hint(DISABLE_DEPTH_TEST); // avoids z-fighting
15.   
16.   font = loadFont("Helvetica-50.vlw"); 
17.   textFont(font);
18.   
19.   cam = new PeasyCam(this, 400, 400, 0, 1500);  // default settings on double click
20.   cam.setMinimumDistance(.001);
21.   cam.setMaximumDistance(20000);
22.   
23.   aList.add("Testing1");
24.   aList.add("Testing2");
25.   aList.add("Testing3");
26.   aList.add("Testing4");
27.   aList.add("Testing5");
28.   aList.add("Testing6");
29.   aList.add("Testing7");
30.   aList.add("Testing8");
31.   aList.add("Testing9");
32.   aList.add("Testing10");
33.   aList.add("Testing11");
34.   aList.add("Testing12");
35. }
36. 
    
37. void draw(){
38.   background(0);
39.   
40.   translate(width/2, height/2);
41.   
42.   rot-=.001;
43.   showText();
44.   cam.setRotations(0, 0, rot);
45. }
46. 
    
47. void showText() {
48.   for (int i=0; i<aList.size(); i++) {
49.     String label = aList.get(i);
50.     float labelWidth = textWidth(label);
51.     float textHeight = 50;
52.     float[] rotations = cam.getRotations();
53.     
54.     pushMatrix();
55.       translate(40*(i+4)*cos(i),
56.                 100+40*(i+4)*sin(i),
57.                 textHeight);
58.                 
59.       pushMatrix();
60.         // Make text always face camera
61.         rotateX(rotations[0]);
62.         rotateY(rotations[1]);
63.         rotateZ(rotations[2]);
64.         
65.         translate(0,0,1);
66.         fill(100);
67.         rect(- labelWidth/2 - 2, -textHeight -1.5 ,labelWidth+4, textHeight+textHeight/2);
68.         
69.         fill(255);
70.         textSize(textHeight); textAlign(CENTER);
71.         text(label, 0, 0, 0);
72.       popMatrix();
73.     popMatrix();
74.   }
75. }
