Here is the code. I have it in different tabs and I don't know how to display the code in this manner, so I will copy and paste as best I can. Thank you in advance!

Ship Sp;

Alien Al;

ArrayList<Bullet> bList;

int bulletDelay;

void setup()

{

  size(800, 600);

  //smooth();

  Al = new Alien();

  Sp = new Ship(10);

  bList = new ArrayList<Bullet>();

}

void draw()

{

  float deltaX = pmouseX - Sp.centerX;

  float deltaY = pmouseY - Sp.centerY;

  // deltaX = Sp.easing;

  //deltaY = Sp.easing;

  background(0);

  Sp.rotateShip(deltaX, deltaY);

  Sp.displayShip();

  // Sp.keyPressed();

  Sp.move();

  Al.displayAlien();

  Al.move();

  if (keyPressed)

  {

   Sp.speedUp();

  }

  else

  {

   Sp.slowDown();

  }

  bulletDelay++;

  for (int i=0; i < bList.size(); i++)

  {

   Bullet blt = bList.get(i);

   blt.drawBullet();

   blt.move();

  }

  if (mousePressed)

  {

   if (bulletDelay % 40 == 0)

   {

   float directionX = (mouseX - Sp.centerX);

   float directionY = (mouseY - Sp.centerY);

   float n = directionX * directionX + directionY * directionY;

   n = sqrt(n);

   directionX = directionX/n;

   directionY = directionY/n;

   Bullet b = new Bullet(Sp.centerX, Sp.centerY, 5, directionX, directionY);

   bList.add(b);

   }

  }

}

class Alien

{

  float x, y;

  float s;

  float centerX, centerY;

  float xSpeed;

  float ySpeed;





  Alien()

  {

   centerX = width/2;

   centerY = height/2;

   //this.s = s;

   // sze = s;



   //fly = 10;

   //len = s;

   //easing = .05;

  // rotation = 0;

   xSpeed = .7;

   ySpeed = .7;

  }



  void move()

  {

   //centerX += xLoc;

   //centerY += yLoc;



   centerX += xSpeed;

   centerY += ySpeed;

  }



  void displayAlien()

  {

   fill(255);

   smooth();

   rectMode(CENTER);

   rect(centerX, centerY, 10, 10);

  }

}

class Bullet

{

  float x, y, s;

  float xSpeed, ySpeed;

  float bulletSpeed;





  Bullet(float xPos, float yPos, float sz, float xSpeed, float ySpeed)

  {

   x = xPos;

   y = yPos;

   s = sz;

   bulletSpeed = 6;

   this.xSpeed = xSpeed*bulletSpeed;

   this.ySpeed = ySpeed*bulletSpeed;

  }



  void drawBullet()

  {

   rectMode(CENTER);

   rect(x,y,s,s);

  }



  void move()

  {

   y += ySpeed;

   x += xSpeed;

  }

}

class Ship

{

  float x, y;

  //float xLoc, yLoc;

  float fly;

  float hit;

  float s;

  float len;

  float centerX;

  float centerY;

  float rotation;

  float easing;

  float stop;

  float xSpeed;

  float ySpeed;

  PVector shipLoc;

  Ship(float s)

  {

   // x = width/2;

   //y = height/2;

   centerX = width/2;

   centerY = height/2;

   this.s = s;

   hit = 0;

   fly = 10;

   len = s;

   easing = .05;

   rotation = 0;

   xSpeed = .7;

   ySpeed = .7;

   shipLoc =

  }

  void move()

  {

   //centerX += xLoc;

   //centerY += yLoc;

   centerX += xSpeed;

   centerY += ySpeed;

   if (centerY >= height)

   {

   centerY = 1;

   }

   if (centerY <= 0)

   {

   centerY = 600;

   }

   if (centerX >= width)

   {

   centerX = 1;

   }

   if (centerX <= 0)

   {

   centerX = width;

   }

  }

  void speedUp()

  {

   switch(key)

   {

   case 'w':

   y-= ySpeed--;

   break;

   case 's':

   y+= ySpeed++;

   break;

   case 'a':

   x-= xSpeed--;

   break;

   case 'd':

   x+= xSpeed++;

   break;

   }

  }

  void slowDown()

  {

   xSpeed *= .9;

   ySpeed *= .9;

  }

  void rotateShip(float x, float y)

  {

   rotation = atan2(y, x);

  }

  void displayShip()

  {

   smooth();

   fill(255);

   //fill(255, 0);

   pushMatrix();

   translate(centerX, centerY);

   rotate(rotation);

   //translate(x, y);

   beginShape();

   for (float theta = 0; theta < 2 * PI; theta += 2 *PI / 3)

   {

   float pX = cos(theta) * len;

   float pY = sin(theta) * len;

   vertex(pX, pY);

   }

   endShape(CLOSE);

   popMatrix();

  }

}

Also, if any one could direct me towards some good examples of how one might cause one object to follow another I would be extremely grateful. Not a huge deal though.
