How can I implement 2D physics in Pygame using Pymunk?

You can start by installing Pymunk and then integrating it with Pygame. Would you like a code example?

Yes, please provide a simple code example.

Here's a basic example:

import pygame
import pymunk

# Initialize Pygame and Pymunk
pygame.init()
space = pymunk.Space()

# Create a ball
body = pymunk.Body(1, pymunk.moment_for_circle(1, 0, 15))
body.position = 100, 100
shape = pymunk.Circle(body, 15)
shape.elasticity = 0.95
space.add(body, shape)

# Main loop
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
    space.step(1/50.0)
    # Draw your objects here

This sets up a simple ball that falls due to gravity. Would you like to know more about adding controls?

That looks great! How do I add controls to move the ball?

You can add keyboard controls by checking for key presses in the main loop. For example:

keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT]:
    body.apply_force_at_local_point((-1000, 0))
if keys[pygame.K_RIGHT]:
    body.apply_force_at_local_point((1000, 0))

This will allow you to move the ball left and right. Would you like to add more features?
