Hands-on Pygame Analysis of Code : Simple Ball Game

Each part of this code contributes to creating a basic, yet interactive and fun, ball game. It covers essential programming concepts in Pygame, such as handling user input, collision detection, and rendering graphics, providing a solid foundation for beginners in game development.

Let’s go through the Python Pygame code for a simple ball game, providing a detailed commentary. This will help understand each part of the code and its purpose in the game.

import pygame
import random

# Initialisation de Pygame
pygame.init()

# Window Dimensions
WIDTH, HEIGHT = 800, 600
win = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Jeu de Football LEAD Morocco")

# Load Background Image
background = pygame.image.load("background.png")  # Ensure "background.png" is in the same directory as your script

# Load Icon Image
icon = pygame.image.load("icon.png")  # Replace "icon.png" with the name of your icon image

# Setting Window Icon
pygame.display.set_icon(icon)  # Image must be ICO or PNG format, size 32x32 or 64x64 pixels

This section initializes Pygame and sets up the main window of the game with predefined width and height.
It loads a background image and an icon for the game window, which enhances the visual appeal and identity of the game.

# Colors
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
ORANGE = (255, 165, 0)
YELLOW = (255, 255, 0)
PINK = (255, 192, 203)
PURPLE = (128, 0, 128)
BROWN = (165, 42, 42)
GRAY = (128, 128, 128)
CYAN = (0, 255, 255)
TURQUOISE = (64, 224, 208)
GOLD = (255, 215, 0)
SILVER = (192, 192, 192)

Here, different colors are defined using RGB (Red, Green, Blue) values. These colors will be used later in the game for drawing and design purposes.

# Player
player_width, player_height = 100, 20
player_x, player_y = (WIDTH - player_width) // 2, HEIGHT - player_height - 20
player_speed = 0.1

The player’s paddle is defined in terms of width, height, initial position, and speed. This represents the object the player controls in the game.

# Ball
ball_width, ball_height = 20, 20
ball_x, ball_y = random.randint(0, WIDTH - ball_width), HEIGHT // 2
ball_speed_x, ball_speed_y = 0.1, 0.1  # Reduced speed for a slower game

The ball is defined with its size, initial random position, and speed. The ball’s movement will be the central part of the game’s mechanics.

# Score
score = 0
font = pygame.font.Font(None, 36)

Initializes the score and sets the font for displaying the score. This will be used to track and display the player’s score throughout the game.

# Game Loop
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

The main game loop starts, which will keep running until the player decides to quit the game. This loop is the heart of the game, where all actions and updates take place.

    # Player Controls
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT] and player_x > 0:
        player_x -= player_speed
    if keys[pygame.K_RIGHT] and player_x < WIDTH - player_width:
        player_x += player_speed

This part handles player input for moving the paddle left or right. It checks if the left or right arrow keys are pressed and moves the paddle accordingly, ensuring it doesn’t go off the screen.

    # Ball Movement
    ball_x += ball_speed_x
    ball_y += ball_speed_y

    # Ball Bounce on Edges
    if ball_x <= 0 or ball_x >= WIDTH - ball_width:
        ball_speed_x *= -1
    if ball_y <= 0:
        ball_speed_y *= -1

These lines control the movement of the ball, including making it bounce off the window’s edges. The ball changes direction when it hits a wall.

    # Ball Collision with Player
    if player_x <= ball_x <= player_x + player_width and player_y <= ball_y <= player_y + player_height:
        ball_speed_y *= -1
        score += 1

Detects collision between the ball and the player’s paddle. If a collision occurs, the ball bounces back, and the player’s score increases.

    # Reset Ball if Lost
    if ball_y >= HEIGHT:
        ball_x, ball_y = random.randint(0, WIDTH - ball_width), HEIGHT // 2
        ball_speed_x, ball_speed_y = 0.1, 0.1
        score -= 1

If the ball goes past the paddle and reaches the bottom of the window, the ball resets to a random position at the top, and the player loses a point.

    # Drawing Background, Player, Ball, and Score
    win.blit(background, (0, 0))
    pygame.draw.rect(win, GREEN, (player_x, player_y, player_width, player_height))
    pygame.draw.ellipse(win, RED, (ball_x, ball_y, ball_width, ball_height))
    text = font.render("Score: " + str(score), True, BLUE)
    win.blit(text, (10, 10))

    pygame.display.update()

This section is responsible for drawing the game’s elements: the background, player’s paddle, ball, and the score. It updates the display to reflect these changes.

# Close Pygame
pygame.quit()

About game speed :

It’s important to understand that the speed of the game as experienced by the player can be influenced by the machine’s performance on which it is running. In our Pygame code, there is a provision to adjust the game’s speed, which is particularly useful for tailoring the gaming experience to different hardware capabilities. The variables ball_speed_x, ball_speed_y, and player_speed are set to specific values, but they are completely adjustable.

For instance, setting these speed variables to a higher value, such as 3, will make the game faster, providing a more challenging experience. Conversely, setting them to a lower value, like 1, slows down the game, making it more manageable for beginners or those playing on less powerful hardware. Furthermore, these speed variables can accept floating-point values, such as 0.1 or 0.5. This allows for fine-tuning the speed with precision, enabling a smooth and controlled gameplay experience. Such flexibility in adjusting the game speed is essential to cater to a wide audience with varying preferences and device capabilities.
