Here is the code to make a Pac-Man game 👇🏼

- Install Pygame if you don’t have it already:

pip install pygame



Python Code for a Basic Pac-Man Game:

import pygame
import sys

# Initialize Pygame
pygame.init()

# Screen settings
WIDTH, HEIGHT = 600, 400
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Pac-Man Game")

# Colors
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
YELLOW = (255, 255, 0)
RED = (255, 0, 0)

# Clock for frame rate
clock = pygame.time.Clock()
FPS = 30

# Pac-Man settings
pacman_size = 20
pacman_x, pacman_y = WIDTH // 2, HEIGHT // 2
pacman_speed = 5
pacman_dir = "RIGHT"

# Ghost settings
ghost_size = 20
ghost_x, ghost_y = 100, 100
ghost_speed = 2

# Collectibles (dots)
dots = [(50, 50), (150, 100), (300, 200), (400, 300), (500, 150)]
dot_radius = 5

# Score
score = 0

# Game loop
running = True
while running:
screen.fill(BLACK)

# Handle events
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False

# Move Pac-Man
keys = pygame.key.get_pressed()
if keys[pygame.K_UP]:
pacman_y -= pacman_speed
pacman_dir = "UP"
if keys[pygame.K_DOWN]:
pacman_y += pacman_speed
pacman_dir = "DOWN"
if keys[pygame.K_LEFT]:
pacman_x -= pacman_speed
pacman_dir = "LEFT"
if keys[pygame.K_RIGHT]:
pacman_x += pacman_speed
pacman_dir = "RIGHT"

# Keep Pac-Man on screen
pacman_x = max(0, min(WIDTH - pacman_size, pacman_x))
pacman_y = max(0, min(HEIGHT - pacman_size, pacman_y))

# Draw Pac-Man
if pacman_dir == "RIGHT":
pygame.draw.pacman = pygame.draw.polygon(screen, YELLOW, [(pacman_x + pacman_size, pacman_y + pacman_size )
