Pygame Snake, Pt. 5

Your code is now handling the boundary conditions correctly, ensuring that the snake wraps around when it goes off the screen. This is a crucial part of implementing the game mechanics for Snake.

Here's your updated code with some minor improvements and comments:

python
 
1import pygame
2
3# Initialize Pygame
4pygame.init()
5
6# Screen dimensions
7W = 20
8H = 20
9S = 30  # Square size
10screen = pygame.display.set_mode((W * S, H * S))
11
12# Snake starting position and velocity
13snake = [pygame.Vector2(W // 2, H // 2)]
14vel = pygame.Vector2(1, 0)
15grow = 0
16
17def place_food():
18    while True:
19        pos = pygame.Vector2(pygame.math.Vector2(random.randint(0, W - 1), random.randint(0, H - 1)))
20        if pos not in snake:
21            return pos
22
23food_pos = place_food()
24
25# Main game loop
26running = True
27while running:
28    for event in pygame.event.get():
29        if event.type == pygame.QUIT:
30            running = False
31        elif event.type == pygame.KEYDOWN and event.key in key_vel:
32            vel =
