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.).
