I have searched and tried, but I can't get my first test game working. You just click circles to gain points and theyre bouncing around the screen, but it won't recognise that you've clicked one. I have it recording score, but it can't record anything because of this problom I have. Is there any simple way to do it?

I am very new to this 'Processing' tool, only at it a week.

I've seen most people asking questions post their whole code, so I might as well put it up. It could probobly speed this up anyway;

1. PFont f;
2. int xdirection = 1;  // Left or Rightint ydirection = 1;  // Top to Bottom
3. int value = 0;
4. Clickball ball1;
5. Clickball ball2; // Two objects!
6. Clickball ball3;
7. Clickball ball4;
8. 
   
9. void setup() {
10.   size(200,200);
11.   noStroke();
12.   f = loadFont("AgencyFB-Reg-48.vlw");
13.   ball1 = new Clickball(color(255,0,0),10,100,2,8);
    
14.   ball2 = new Clickball(color(0,0,255),10,130,1,7);
15.   ball3 = new Clickball(color(0,255,0),10,100,3,8);
    
16.   ball4 = new Clickball(color(0,255,255),10,130,4,9);
17. }
18. 
    
19. void draw() {
20.   background(255);
21.   textFont(f,36);
22.   stroke(175);
23.   line(width/2,0,width/2,height);
24.   fill(0);
25.   textAlign(CENTER);
26.   text("Score: " + value ,width/2,60);
27.   ball1.bounce();
28.   ball1.mouseClicked();
29.   ball1.display();
30.   ball2.bounce();
31.   ball2.mouseClicked();
32.   ball2.display();
33.   ball3.bounce();
34.   ball3.mouseClicked();
35.   ball3.display();
36.   ball4.bounce();
37.   ball4.mouseClicked();
38.   ball4.display();
39. 
    
40. }
41. 
    
42. //score(width/2, height/2, 50, 50);
43. 
    
44. class Clickball {
    
45.   color c;
46.   float xpos;
47.   float ypos;
48.   float xspeed;
49.   float yspeed;
50. 
    
51.   Clickball(color tempC, float tempXpos, float tempYpos, float tempXspeed, float tempYspeed) {
    
52.     c = tempC;
53.     xspeed = tempXspeed;
54.     yspeed = tempYspeed;
    
55.       if (xpos > width-200 || xpos < 0) {
56.       xdirection *= -1;
57.       }
58.         if (ypos > height-200 || ypos < 0) {
59.     ydirection *= -1;
60.   }
61.   }
62. 
    
63.   void display() {
64.     stroke(0);
65.     fill(c);
66.     ellipseMode(CENTER);
67.     ellipse(xpos,ypos,20,20);
68.   }
69.   //Supposed to add 50 points per click. fix later.
70.   void mouseClicked() {
71.     if (dist(200,200,mouseX,mouseY) < 50) {
72.     if (value >= 1) { value = 0; }
73.     else if (value == 0) { value = 1; }
74.   }
75.   }
76.   {
77.   if(value == 0) {
78.     value = + 50;
79.   } else {
80.     value = +0;
81.   }
82.   }
83.  
    
84.   void bounce() {
85.     xpos = xpos + xspeed;
86.    
    
87.     xpos = xpos + ( xspeed * xdirection );
88.     ypos = ypos + ( yspeed * ydirection );
89.  
    
90.     if (xpos > width) {
91.       xspeed = xspeed * -1;
92.     }
93.     if (xpos < 0) {
94.       xspeed = xspeed * -1;
95.     }
96.     if (ypos > height) {
97.       yspeed = yspeed * -1;
98.     }
99.     if (ypos < 0) {
100.       yspeed = yspeed * -1;
101.     }
102.   }
103. }

Any help is appreciated.
