Need help with a restart button for my Snake Game please

I need help understanding how to make a restart button on my snake game. I want it to be the Shift key but it won't allow me to so I made the restart key to be 'r' and it still doesn't work.

//MY CODE

int WIDTH = 700;

int HEIGHT = 600;

int SQSIZE = 10;

int x = 350;

int y = 300;

int foodx = 500;

int foody = 80;

int xspeed, yspeed;

int speed = SQSIZE;

int [] bodyx = new int [80];

int [] bodyy = new int [80];

int score = 0;

int endgame;

int r;

boolean restart = false;

void setup()

{

smooth();

frameRate(14);

size (WIDTH, HEIGHT);

x = 350;

y = 300;

for (int i = 0; i < bodyx.length; i++)

{

bodyx [i] = x;

bodyy [i] = y;

}

}

void draw() { background(76, 142, 54, 105);

//lines

for (int i = 0; i < 600; i = i+10)

{

stroke(203, 240, 191, 105);

line(0, i, 700, i);

}

for (int i = 0; i < 700; i = i+10)

{

line(i, 0, i, 600);

}

//SNAKE

stroke(x, y, 0);

fill(x, y, 255);

rect(x, y, SQSIZE, SQSIZE);

//FOOD

fill(133, 33, 250, 267);

//SCORE

textSize(30);

//food

if ((x == foodx) && (y == foody))

{

foodx = int(random(2, 68))*SQSIZE;

foody = int(random(2, 58))*SQSIZE;

rect(foodx, foody, SQSIZE, SQSIZE);

score = score + 1;

}

bodyx[score+1] = x;

bodyy[score+1] = y;

//Body expanding every time food is eaten

for (int i = 0; i < score+1; i++)

{

    int x;
int y; 

void setup(){
  size(220,220);
  reset();
}

void draw(){
  background(0);
  x++;
  rect(x,x,y,y);
}

void keyPressed(){
  if(key=='r') reset();
}

void reset(){
  x = 5;
  y = int(random(5,20));
}

    Your sketch's state is entirely defined by the variables that store the information that your sketch needs to remember. To reset the state to how it was at the start, simply change the value stored in all your variables back to what they were when you sketch started.

    So I did everything and I went to play the processing and it says 'Duplicate field SNAKE_GAME.WIDTH and it's highlighting the 'int WIDTH = 700;' What does that mean?

    @TfGuy44

  • PhiLhoPhiLho

    See also How to format code and text...

    About WIDTH: no idea why you have this error, but Processing practice is to define numbers values in size(), and to use built-in width and height variables...

    you probably have this line twice:

    'int WIDTH = 700;'

    Anyway, show your new entire code please

    I got it working...

    you must check r with this line

         if (key == 'r')

    (use key please, not keyCode)

    in reset() you also must say speed = SQSIZE;
