screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption('Real-Time Terrain Generation')

def generate_terrain(screen, width, height, tile_size):
    '''Generate the terrain by looping over each grid position.'''
    for y in range(0, height, tile_size):
        for x in range(0, width, tile_size):
            # Calculate Perlin noise value for a specific position
            noise_val = noise.pnoise2(x / NOISE_SCALE, y / NOISE_SCALE, octaves=6)
            if noise_val < -0.05:
                color = COLORS['water']
            elif noise_val < 0:
                color = COLORS['sand']
            elif noise_val < 0.35:
                color = COLORS['grass']
            elif noise_val < 0.6:
                color = COLORS['rock']
            else:
                color = COLORS['snow']
            
            # Draw the terrain tile
            pygame.draw.rect(screen, color, (x, y, tile_size, tile_size))

def main():
    clock = pygame.time.Clock()
    running = True

    # Main loop
    while running:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False

        # Generate terrain on every frame
        generate_terrain(screen, WIDTH, HEIGHT, TILE_SIZE)

        # Update the full display Surface to the screen
        pygame.display.flip()

        # Cap the maximum frame rate at 30fps
        clock.tick(30)

    pygame.quit()

# Run the main function
if __name__ == '__main__':
    main()

Code Output:

The program generates a window titled ‘Real-Time Terrain Generation’ with a size of 800×600 pixels. The screen continuously redraws a grid of tiles where each represents a terrain type based on its Perlin noise value. The colors of the terrain range from blue for water, light brown for sand, green for grass, grey for rock, to white for snow.

Code Explanation:

The provided code uses Pygame to generate and display a real-time procedural terrain grid, which changes dynamically as the program runs. Here’s a breakdown of how it works:

  • Importing Libraries: We start by importing the pygame library for rendering graphics, the random library for generating random numbers, noise for generating Perlin noise, and numpy for numerical operations.
  • Constants Setup: We define constants like screen width and height, tile size, and noise scale that configure our terrain grid and noise generation.
  • Terrain Colors: We have a dictionary that maps different terrain types to specific RGB color values.
  • Pygame Initialization: We initialize Pygame and create a window of defined width and height.
  • The generate_terrain Function: This function is responsible for creating the terrain. It iterates over the screen’s grid positions and uses Perlin noise to determine the terrain type for each tile. The noise value maps to a terrain type, such as water, sand, grass, rock, or snow, which is then drawn onto the screen using Pygame’s drawing functions.
  • The main Function: This is the entry point for our game loop. Within the loop, the program handles events like closing the window and repeatedly calls the generate_terrain function to update the terrain. The display is refreshed with changes, and the loop runs at a capped frame rate of 30fps to ensure it doesn’t run too fast.
  • Executing the Program: Finally, the main function is called when the script is executed, which starts the whole process.

Overall, the code uses the power of noise functions to generate interesting and variable terrains in real-time, exhibiting the dynamic nature of procedural generation. Thanks for stopping by – keep on coding! And remember, in a world full of zeros, strive to be the significant one. 😉
