App 6: Make a Game, Snake in Pygame / Build Snake

Lesson 4 of 10

Moving the snake

Each frame, add a new head one cell in the current direction and remove the tail. That's the whole trick to snake movement.

direction = (1, 0)

head_x, head_y = snake[0]
new_head = (head_x + direction[0], head_y + direction[1])
snake.insert(0, new_head)
snake.pop()
