hey, got something here thats truly bugging me out... maybe someone can take a look? (i already know that the .tif's won't work, they are just in my data folder as place holders for now.)

tab1: skyeSelf

// variables
int introLineY, ySpot, x, y;
PImage[] Zones = new PImage[7];
PImage maskMe;
triggerPoint tP = new triggerPoint();



void setup()
{
 Zones[0] = loadImage("48.tif");
 Zones[1] = loadImage("54.tif");
 Zones[2] = loadImage("86.tif");
 Zones[3] = loadImage("103.tif");
 Zones[4] = loadImage("128.tif");
 Zones[5] = loadImage("136.tif");
 Zones[6] = loadImage("158.tif");
 println ("y[6]");
 size(800,533);
 x=width;
 y=height;
 tP.fillX();
 tP.fillY();
 background (0);
}

void draw()
{
 strokeWeight (3);
 stroke (#930000);
 line (width/2, height/2-40, width/2, height/2+40);
}

tab2: toolBox

class toolBox {
 int minColorVal = 0;
 int maxColorVal = 255;
 int hCenter;           // horizontal center of screen
 int vCenter;           // vertical center of screen
 
// constructor
 toolBox() {
   hCenter = width/2;
   vCenter = height/2;
 }
 
// generating a random integer between and including minVal and maxVal
 int randomInt(int minVal, int maxVal) {
   return int(random(minVal, maxVal+1));  
 }

// generating a color with random R, B, and B values
 color randomColor() {
   return color(
     randomInt(minColorVal, maxColorVal),  // random R value
     randomInt(minColorVal, maxColorVal),  // random G value
     randomInt(minColorVal, maxColorVal)   // random B value
   );
 }

// generate color with random hue value
 color randomHueColor() {
   colorMode(HSB, 360);
   return color(
     randomInt(minColorVal, 360),   // random Hue
     360,                           // full Saturation
     360                            // full Brightness
   );            
 }

// generate color with random saturation value
 color randomSaturationColor(int hueVal) {
   colorMode(HSB, 360);
   return color(
     hueVal,                        // specified Hue
     randomInt(minColorVal, 360),   // random Saturation
     360                            // full Brightness
   );            
 }

// generate color with random brightness value
 color randomBrightnessColor(int hueVal) {
   colorMode(HSB, 360);
   return color(
     hueVal,                        // specified Hue
     360,                           // random Saturation
     randomInt(minColorVal, 360)    // full Brightness
   );
