Hi there!

I'm making a small school project where I'm suposed to create some visual feedback to a wisthle input.

What the sketch does until now is create a few 'branches' (I think I can call them this way...) according with the volume of the whistle.

What I want to do now is turn each of these branches an independent 'object'. I want all of them to have a small float movement. I don't know if I made myself clear, sorry...

So, my questions are: What it's the best way to do it? Do I need to create an array or something?

Thank you all!

Here's my code:

[Key pressed = Cleans background]

2. import ddf.minim.*;
3. 
   
4. Minim minim;
5. AudioInput in;
6. 
   
7. int positionX = 350;
8. int positionY = 150;
9. 
   
10. int soundVol = 0; 
11. 
    
12. int velocityX;
13. int velocityY;
14. 
    
15. void setup() {
16.   size (700, 300);
17.   background(0);
18.   smooth();
19.   frameRate(30);
20. 
    
21.   minim = new Minim(this);
22.   minim.debugOn();
23. 
    
24.   in = minim.getLineIn(Minim.MONO, 512);
25. }
26. 
    
27. void draw() {
28.   //backColor();
29.   dateTime();
30. 
    
31.   for (int i = 0; i < in.bufferSize() - 1; i++)
32.   {
33. 
    
34. 
    
35.     soundVol = int(in.right.get(i)*50) + int(in.left.get(i+1)*50);
36.   }
37. 
    
38.   soundVol = constrain(soundVol, 0, 100);
39. 
    
40.   velocityX = soundVol;
41.   velocityY = soundVol;
42. 
    
43.   positionX = width/2;
44.   positionY = height/2;
45. 
    
46.   positionX = positionX + velocityX;
47.   positionY = positionY + velocityY;
48. 
    
49.   if (soundVol > 1) {
50.     
51.     positionX = positionX + (int (random(soundVol*-2, soundVol*2)));
52.     positionY = positionY + (int (random(soundVol*-2, soundVol*2)));
53.     
54.   }
55. 
    
56.   println(soundVol);
57. 
    
58.   fill(255);
59.   ellipse (positionX, positionY, 5, 5);
60.   stroke(255);
61.   line(width/2, height/2, positionX, positionY);
62. 
    
63.   if (keyPressed == true) {
64.     background(0);
65.   }
66. }
67. 
    
68. void stop()
69. {
70.   in.close();
71.   minim.stop();
72. 
    
73.   super.stop();
74. }
75. 
    
76. void dateTime () {
77.   fill(100);
78.   rect(15, 260, 75, 35);
79.   fill(255);
80.   PFont font;
81.   font = loadFont("Helvetica-Light-48.vlw");
82.   textFont(font, 12);
83.   text (year()+" /"+month()+" /"+day(), 20, 275);
84.   text (hour()+" : "+minute()+" : "+second(), 20, 290);
85. }
