Retro games feel incredible on the canvas API. This snake array pushes new head coordinates and pops the tail unless it eats the apple.

The Movement Update

JAVASCRIPT CODE

let snake = [{x: 10, y: 10}];
let velocity = {x: 1, y: 0};

function gameLoop() {
  const head = { x: snake[0].x + velocity.x, y: snake[0].y + velocity.y };
  snake.unshift(head);
  
  if (head.x === food.x &amp;&amp; head.y === food.y) {
    score++;
    placeFood();
  } else {
    snake.pop(); // Remove tail if no food eaten
  }
}
