Sorry but i'm kind of new to processing and i've never really worked with text before. I was wondering if anyone could help me figure out how to get the transparent words on my sketch to become more solid in colour as  the mouse is moved over them individually.

This may not help but i have  the code.

PImage img0;
PImage img1;
PImage img2;
PFont font1;
PFont font2;


void setup()
{
    size(504, 378);
 smooth();
  img0 = loadImage("Journeybackyard040.JPG");
  img1 = loadImage("Journeybackyard039.JPG");
  img2 = loadImage("Journeybackyard041.jpg");
   font1= loadFont ("OratorStd-60.vlw");
    font2= loadFont ("OratorStd-200.vlw");
}
 
void draw()
{
    background(255);
       tint(255,200);
  image (img0,0,0);
  tint(255, 150);
    image (img1,0,0);
    tint(255,50);
  image (img2,0,0);
 
 
 textFont(font1,40);
  textAlign (LEFT);
   fill(255,40);
   text("0573",50,300);
   text("0574",400,60);
   text("0575",100,100);
   text("0576",0,0);
   text("0577",0,0);
  
   textFont(font2,150);
text("0574",200,60);
text("0579",50,300);
text("0579",300,400);

 textFont(font2,110);
text("0579",0,80);

textFont(font2,200);
text("0579",-10,450);
textFont(font2,90);
text("0572",200,180);
  }
 
 

there isn't anything in here about the changing opacity but can anyone show/teach me how i program the void mousemoved for this?

I'm relatively new to processing and I need to make an image array where it goes through pictures when the mouse is clicked.  But I'm having trouble and am not really sure how an array works.

Here's one set of coding I tried but i keep getting the null pointer exception and it won't load my pictures.

int numFrames = 5; // The number of animation frames
PImage[] images = new PImage[numFrames]; // Image array

void setup() {
  size(504,378);
  frameRate(30); // Maximum 30 frames per second

  // Automate the image loading procedure. Numbers less than 100
  // need an extra zero added to fit the names of the files.
  for (int i = 0; i < images.length; i++) {
    // Construct the name of the image to load
    String imageName = "Journeybackyard" + nf(i, 2) + ".jpg";
    images[i] = loadImage(imageName);
  }
}

void draw() {
  // Calculate the frame to display, use % to cycle through frames
  int frame = frameCount % numFrames;
  image(images[frame], 0, 0);
}

Then I tried,

/*PImage[] images = new PImage[5];
PImage img = new PImage();
float x;
float y;
int r;
 
void setup()
{
  size(504,378);
  for (int i = 0; i < images.length; i ++)
   {
    images[i] = loadImage( i +".JPG");
   }
   for(int i=0; i  < images.length; i ++){

}
}
void draw()
{
  if(mousePressed)
  {
    for(int count = 0;count<20;count ++)
    {
      r=int(random(9));
      image(images[r],0,0);
    }
  }
}
 
PImage img0;
PImage img1;
PImage img2;
PImage img3;
PImage img4;
PImage img5;

void setup(){
 
    size(504, 378);
   
    PImage[] im = new PImage[6];
   
img0[0] = loadImage("Journeybackyard050.JPG");
img1[1] = loadImage("Journeybackyard051.JPG");
img2[2] = loadImage("Journeybackyard052.JPG");
img3[3] = loadImage("Journeybackyard053.JPG");
img4[4] = loadImage("Journeybackyard054.JPG");
img5[5] = loadImage("Journeybackyard055.JPG");

  image (img0, 0,0) ;  
  image (img1, 0,0) ;  
  image (img2, 0,0) ;
  image (img3, 0,0) ;
  image (img4, 0,0) ;
  image (img5, 0,0) ;

and that wouldn't work either because it stated that it couldn't convert the images from a PImage to the integer.

I'm probably asking a dumb question but would someone be able to give me some major assistance?
