Hi

I am new to processing, I am working on a Pacman assignment and finding it quite difficult, if anyone can help me I would be very grateful.

So far I have managed to create a Pacman class and object which moves with KeyPressed via the arrow keys, I have managed to create a class for the dots and created the object, covering the canvas with ellipses similar to a gird. I do not know how to make Pacman eat the dots, once in contact, I have attempted a boolean and if statement, but I am not sure what I have done wrong, the program runs. I also have not been able to make Pacman face the direction he is moving in.

Here is all of the code to better explain

// main program
float cx = 250,
      cy = 250,
      dx = 0,
      dy = 0;
 PImage Pac;
 Pacman P1;
 
 Food F;
 int Fx,
     Fy,
     S,
     G;
 
 void setup() {
  size(500, 500);
  Pac = loadImage ("Pacman 48x48px.png");
  P1 = new Pacman (cx, cy, dx, dy, Pac);
  F = new Food (Fx, Fy, S, G); 
}



void draw () {
  background (0);
  P1.Move ();
  F.Draw ();
  P1.Draw ();
  Eating() ;
}

void Eating() {
float distance;
distance = sqrt(pow(P1.cx - F.Fx,2) + pow(P1.cy - F.Fy, 2));
if(distance < 10);
}

 
void keyPressed () {
  if (key == CODED) {
    switch (keyCode) {
      case LEFT:
        P1.dy = 0;
        P1.dx = -1;
      break;
    }
  }
  if (width < dy) {
     dy = 500;
  }
  if (key == CODED) {
     switch (keyCode) {
       case RIGHT:
         P1.dy = 0;
         P1.dx = +1;
         break;
     }
  }
if (key == CODED) {
     switch (keyCode) {
       case UP:

         P1.dy = -1;
         P1.dx = 0;
         break;
     }
}
if (key == CODED) {
     switch (keyCode) {
       case DOWN:
         P1.dy = +1;
         P1.dx = 0;
         break;
     }
}

}


HERE is the Pacman Class:

lass Pacman  {
  float cx,
        cy,
        dx,
        dy;
  PImage Pac;
 
       
   Pacman (float cx, float cy, float dx, float dy, PImage Pac){
    this. cx = cx;
    this. cy = cy;
    this. dx = dx;
    this. dy = dy;
    this. Pac = Pac;  
}

void Draw () {
  imageMode (CENTER);
  image (Pac, cx, cy);
}

void Move () {
  cx += dx;
  cy += dy;
      
 }
}


Here is food class:

class Food {
  int Fx,
      Fy;
  int S,
      G;
 
  Food (int Fx, int Fy, int S, int G){
    this.Fx= Fx;
    this.Fy = Fy;
    this.S = S;
    this.G = G;
  }
 
void Draw () {
  G = 30;
  S = 10;
   for(int Fx = 0; Fx <= width; Fx += G){
   for(int Fy = 0; Fy <= height; Fy += G){
   ellipse (Fx, Fy, S, S);
   fill (White);
   stroke (Red);
   }
   }
}
}

color Yellow = color(255, 255, 0);
color Red = color(255, 0, 0);
color Green = color(0, 255, 0);
color Black = color(0, 0, 0);
color White = color(255, 255, 255);
color Blue = color(0, 0, 255);
color Orange = color(255, 127, 0);


This is all the code I have managed to do, if anyone can guide me or show me how to make Pacman at least make the dots disappear when they both come in contact I would be very grateful. Apologies if I am unclear or ambiguous on my problem.

Thanks
