Can you help with my snake game ?

Its_Stunz · March 2017

I am new to processing and I'm making a snake game but I don't know where to start or go about getting the snake the eat the food and create the food in the first place. If you have an suggestions or code to offer it would be very helpful thank you.

final int titleScreen = 1;
final int game = 2;
final int gameOver = 3;
int rectX = 250;
int rectY = 250;
int screen;
int xspeed;
int yspeed;



void setup() {
  size(500, 500);
  background(255);
  smooth();

  screen = titleScreen;
  rectX = 250;
  rectY = 250;          
  xspeed=0;     
  yspeed=0;
}

void draw() {

  switch(screen) {

  case titleScreen:
    titleScreen();
    break;

  case game:
    gameScreen();
    break;

  case gameOver:
    gameOver();
    break;
  }
} 


void titleScreen() {
  background(0);
  smooth();

  fill(255);
  textSize(48);
  rect(135, 355, 227, 60);
  fill(0);
  textAlign(CENTER, TOP);
  text("Play Now!", 250, 355);

  fill(random(0, 255), random(0, 255), random(0, 255));
  textSize(93);
  text("SNAKE!", 250, 115);


  if (mousePressed == true) {
    if ((mouseX > 135)&&(mouseX < 362))
      if ((mouseY > 355)&&(mouseY < 413))
        screen=2;
  }
}

void gameScreen() {

  background(255);

  rect(0, 0, 5, 495);//Left
  rect(0, 0, 495, 5);//Top
  rect(0, 495, 500, 10);//Bottom
  rect(495, 0, 10, 500);//right

  rect(rectX, rectY, 10, 10);

  rectX = rectX +xspeed; 
  rectY = rectY +yspeed;






  if (( rectX == 0)||( rectX > 495)) {
    screen = 3;
  }
  if (( rectY == 0)||( rectY > 495)) {
    screen = 3;
  }
}
void reset() {

  rectX = 250;
  rectY = 250;          
  xspeed=0;     
  yspeed=0;
}
void gameOver() {
  background(0);
  fill(255);
  textSize(48);
  text(" Game over", 250, 150);
  rect(90, 400, 320, 45);
  textSize(32);
  fill(0);
  text(" Press To Play Again", 250, 400);
  if (mousePressed) {  
    reset();
    screen=1;
  }
}

void mousePressed() {
  print("x: " + mouseX + " y: "+ mouseY +"\n");
}
void keyPressed() { 

  if (keyCode==UP || key == 'w') 
  { 
    xspeed=0; 
    yspeed=-2;
  } else if (keyCode==DOWN || key =='s') 
  { 
    xspeed=0; 
    yspeed=2;
  } else if (keyCode==LEFT || key=='a') 
  { 
    xspeed=-2; 
    yspeed=0;
  } else if (keyCode==RIGHT || key =='d') 
  { 
    xspeed=2; 
    yspeed=0;
  }
}

Ok.

step 1: hit ctrl-t in processing for auto-format

Step 2: go back edit your post

Select entire code and leave empty line before and after and hit ctrl-o to format it as code

There, sorry first time using the forums on here

Now have a food position like float foodX,foodY;

Use random to set both (see reference)

Display a red ellipse() or an image at this position

Check snake head with == or dist() against this fruit

Google snake here or use the link in the tag
