I'm writing a code, to track multiple colors after a capture video from my builtin camera. I keep getting the "Unexpected Token : Void" error pointing line 87. I can't figure out why. 

Here's the code: 

2. import processing.video.*;
3. 
   
4. // Capturar Video
5. Capture video;
6. 
   
7. // Declaración de Variables
8. int numcolores=4, t;
9. color [] trackcolor = new color [numcolores]; // Colores a Buscar
10. 
    
11. 
    
12. // Setup
13. 
    
14. void setup() {
15.   size(400,240); // Tamaño Ventana
16.   video = new Capture(this,320,240,30);
17.   
18.   // 
19.   trackcolor = color(255,0,0); //Comenzar Rojo
20.   smooth();
21. }
22. 
    
23. void draw() {
24.   // Capture and display the video
25.   if (video.available()) {
26.     video.read();
27.   }
28.   video.loadPixels();
29.   image(video,0,0,320,240);
30. 
    
31. float worldRecord = 500; 
32.   
33. int closestX = 0; // XY coordinate of closest color
34. int closestY = 0;
35. 
    
36.   // Begin loop to walk through every pixel
37.   for (int x = 0; x < video.width; x ++ ) {
38.     for (int y = 0; y < video.height; y ++ ) {
39.       int loc = x + y*video.width;
40.       
41.       // Color Actual
42.       color currentColor = video.pixels[loc];
43.       float r1 = red(currentColor);
44.       float g1 = green(currentColor);
45.       float b1 = blue(currentColor);
46.       
47.       for(t=0;t<numcolores;t++){
48.       if(colores[k]==color(0,0,0)){
49.       } else{ 
50.       float r2 = red(trackcolor[t]);
51.       float g2 = green(trackcolor[t]);
52.       float b2 = blue(trackcolor[t]);
53.       
54.       // Using euclidean distance to compare colors
55.       d[t] = dist(r1,g1,b1,r2,g2,b2); // We are using the dist( ) function to compare the current color with the color we are tracking.
56. 
    
57.       // If current color is more similar to tracked color than
58.       // closest color, save current location and current difference
59.       if (d[t] < worldRecord) {
60.         worldRecord = d;
61.         closestX = x;
62.         closestY = y;
63.       }
64.     }
65.   }
66. 
    
67.   // We only consider the color found if its color distance is less than 10. 
68.   // This threshold of 10 is arbitrary and you can adjust this number depending on how accurate you require the tracking to be.
69.   if (worldRecord < 10) { 
70.     
71.     // Draw a circle at the tracked pixel
72.     fill(trackcolor);
73.     strokeWeight(4.0);
74.     stroke(0);
75.     ellipse(closestX,closestY,16,16);
76.   }
77. }
78. 
    
79. //void mousePressed() {
80. //  // Save color where the mouse is clicked in trackcolor variable
81. //  int loc = mouseX + mouseY*video.width;
82. //  trackcolor = video.pixels[loc];
83. //}
84. 
    
85. // Al Presionar una tecla, ir guardando colores a buscar
86. 
    
87. void keyPressed(){
88.     if(key=='1'){       // Ficha Color 1
89.       int loc = mouseX + mouseY*video.width;
90.       trackcolor[0] = video.pixels[loc];
91.       
92.     }else if(key=='2'){ // Ficha Color 2
93.         int loc = mouseX + mouseY*video.width;
94.       trackcolor[1]= video.pixels[loc];
95.       
96.     }else if(key=='3'){ // Robot Adelante
97.         int loc = mouseX + mouseY*video.width;
98.       trackcolor[2] = video.pixels[loc];
99.       
100.     }else if(key=='4'){ // Robot Atras
101.         int loc = mouseX + mouseY*video.width;
102.       trackcolor[3] = video.pixels[loc];
