Game Engine

Install Pygame

First, make sure you have Python installed. Then, install Pygame by running:

bashCopy codepip install pygame

Step 2: Create the Game Engine

Create a file named game_engine.py and add the following code:

pythonCopy codeimport pygame
import sys

class GameEngine:
def __init__(self, width, height, title):
    pygame.init()
    self.width = width
    self.height = height
    self.title = title
    self.screen = pygame.display.set_mode((self.width, self.height))
    pygame.display.set_caption(self.title)
    self.clock = pygame.time.Clock()
    self.running = True
def run(self):
    while self.running:
        self.handle_events()
        self.update()
        self.draw()
        self.clock.tick(60)  # Limit the frame rate to 60 FPS
    pygame.quit()
    sys.exit()
def handle_events(self):
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            self.running = False
def update(self):
    """Update game state. Override this in subclasses."""
    pass
def draw(self):
    """Draw on the screen. Override this in subclasses."""
    self.screen.fill((0, 0, 0))  # Clear screen with black
    pygame.display.flip()
class MyGame(GameEngine):
def __init__(self):
    super().__init__(800, 600, "My Game")
def update(self):
    # Update game logic here
    pass
def draw(self):
    super().draw()
    # Draw game elements here
    font = pygame.font.Font(None, 36)
    text = font.render("Hello, Pygame!", True, (255, 255, 255))
    self.screen.blit(text, (350, 280))
if __name__ == "__main__":
game = MyGame()
game.run()

Step 3: Running the Game Engine

1. Open your terminal (or command prompt).
2. Navigate to the directory where you saved game_engine.py.
3. Run the script using the command:bashCopy codepython game_engine.py

How It Works

• Game Engine Class: The GameEngine class initializes Pygame, creates a window, and runs the game loop, which handles events, updates game logic, and draws the screen.
• MyGame Class: This class inherits from GameEngine and can be customized for your specific game. You can override the update and draw methods to implement your game logic and rendering.
• Event Handling: The handle_events method checks for the quit event to close the game.

Additional Features to Consider

This basic structure provides a foundation for your game engine. You can enhance it by adding features like:

• Sprite Management: Create a class to manage game sprites and animations.
• Collision Detection: Implement collision detection between game objects.
• Sound Management: Add sound effects and background music.
• Input Handling: Extend input handling to manage keyboard and mouse actions.
• Game States: Create a system to manage different game states (menu, playing, paused, etc.).
