Basic Game Loop
The following example demonstrates a simple game loop implemented in Python using the `while True` loop. This loop runs continuously, updating the game state and drawing the scene.
>>> import pygame
>>> pygame.init()
>>> screen = pygame.display.set_mode((800, 600))
>>> clock = pygame.time.Clock()
>>> running = True
>>> while running:
... for event in pygame.event.get():
... if event.type == pygame.QUIT:
... running = False
... # Update game logic here
... # Draw game elements here
... pygame.display.flip()
... clock.tick(60)
>>> pygame.quit()
>>> import pygame
>>> pygame.init()
>>> screen = pygame.display.set_mode((800, 600))
>>> clock = pygame.time.Clock()
>>> running = True
>>> while running:
... for event in pygame.event.get():
... if event.type == pygame.QUIT:
... running = False
... # Update game logic here
... # Draw game elements here
... pygame.display.flip()
... clock.tick(60)
>>> pygame.quit()
Sprite Animation
This example shows how to implement sprite animations in Python using Pygame. It loads multiple frames of an image and plays them sequentially to create the illusion of animation.
>>> import pygame
>>> import sys
>>> from pygame.locals import *
>>> pygame.init()
>>> screen = pygame.display.set_mode((640, 480))
>>> clock = pygame.time.Clock()
>>> walk_frames = []
>>> for i in range(8):
... walk_frames.append(pygame.image.load('walk%d.png' % i).convert())
>>> walking_sprite = pygame.sprite.RenderUpdates()
>>> walking_sprite.add(pygame.sprite.Group(walk_frames[0]))
>>> x, y = 50, 50
>>> dx, dy = 5, 0
>>> walk_count = 0
>>> run = True
>>> while run:
... for event in pygame.event.get():
... if event.type == QUIT:
... run = False
... keys = pygame.key.get_pressed()
... if keys[K_LEFT]:
... dx -= 2
... if keys[K_RIGHT]:
... dx += 2
... if keys[K_UP]:
... dy -= 2
... if keys[K_DOWN]:
... dy += 2
... x += dx
... y += dy
... screen.fill((0, 0, 0))
... walking_sprite.update()
... walking_sprite.draw(screen)
... pygame.display.flip()
... clock.tick(30)
>>> pygame.quit()
>>> import pygame
>>> import sys
>>> from pygame.locals import *
>>> pygame.init()
>>> screen = pygame.display.set_mode((640, 480))
>>> clock = pygame.time.Clock()
>>> walk_frames = []
>>> for i in range(8):
... walk_frames.append(pygame.image.load('walk%d.png' % i).convert())
>>> walking_sprite = pygame.sprite.RenderUpdates()
>>> walking_sprite.add(pygame.sprite.Group(walk_frames[0]))
>>> x, y = 50, 50
>>> dx, dy = 5, 0
>>> walk_count = 0
>>> run = True
>>> while run:
... for event in pygame.event.get():
... if event.type == QUIT:
... run = False
... keys = pygame.key.get_pressed()
... if keys[K_LEFT]:
... dx -= 2
... if keys[K_RIGHT]:
... dx += 2
... if keys[K_UP]:
... dy -= 2
... if keys[K_DOWN]:
... dy += 2
... x += dx
... y += dy
... screen.fill((0, 0, 0))
... walking_sprite.update()
... walking_sprite.draw(screen)
... pygame.display.flip()
... clock.tick(30)
>>> pygame.quit()
Collision Detection
This example demonstrates how to detect collisions between two sprites using the `Rect` class from Pygame.
>>> import pygame
>>> import sys
>>> from pygame.locals import *
>>> pygame.init()
>>> screen = pygame.display.set_mode((640, 480))
>>> clock = pygame.time.Clock()
>>> player_img = pygame.Surface([64, 64])
>>> player_rect = player_img.get_rect(center=(320, 240))
>>> enemy_img = pygame.Surface([64, 64])
>>> enemy_rect = enemy_img.get_rect(center=(320, 120))
>>> running = True
>>> while running:
... for event in pygame.event.get():
... if event.type == QUIT:
... running = False
... screen.fill((0, 0, 0))
... player_rect.move_ip(0, -2)
... if player_rect.colliderect(enemy_rect):
... print("Collision detected!")
... player_img.fill((255, 0, 0))
... screen.blit(player_img, player_rect)
... enemy_img.fill((0, 255, 0))
... screen.blit(enemy_img, enemy_rect)
... pygame.display.flip()
... clock.tick(60)
>>> pygame.quit()
>>> import pygame
>>> import sys
>>> from pygame.locals import *
>>> pygame.init()
>>> screen = pygame.display.set_mode((640, 480))
>>> clock = pygame.time.Clock()
>>> player_img = pygame.Surface([64, 64])
>>> player_rect = player_img.get_rect(center=(320, 240))
>>> enemy_img = pygame.Surface([64, 64])
>>> enemy_rect = enemy_img.get_rect(center=(320, 120))
>>> running = True
>>> while running:
... for event in pygame.event.get():
... if event.type == QUIT:
... running = False
... screen.fill((0, 0, 0))
... player_rect.move_ip(0, -2)
... if player_rect.colliderect(enemy_rect):
... print("Collision detected!")
... player_img.fill((255, 0, 0))
... screen.blit(player_img, player_rect)
... enemy_img.fill((0, 255, 0))
... screen.blit(enemy_img, enemy_rect)
... pygame.display.flip()
... clock.tick(60)

... self.parent = parent
... self.position = position
... self.g = 0
... self.h = 0
... self.f = 0
>>> def heuristic(a, b):
... return ((a[0] - b[0]) ** 2 + (a[1] - b[1]) ** 2) ** 0.5

... total_path = [current]
... while current in came_from:
... current = came_from[current]
... total_path.append(current)
... return list(reversed(total_path))
>>> def astar(maze, start, end):
... start_node = Node(None, start)
... end_node = Node(None, end)
... open_list = [start_node]
