能给我写一个贪吃蛇游戏代码吗?
当然可以!以下是一个简单的贪吃蛇游戏的 Python 代码示例:
import pygame import random # 游戏窗口大小 WINDOW_WIDTH = 800 WINDOW_HEIGHT = 600 # 蛇身和食物大小 CELL_SIZE = 20 # 颜色定义 BLACK = (0, 0, 0)
GREEN = (0, 255, 0)
RED = (255, 0, 0) # 初始化 Pygame pygame.init()
window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption("贪吃蛇游戏") # 蛇类 class Snake: def __init__(self):
self.body = [(WINDOW_WIDTH/2, WINDOW_HEIGHT/2)]
self.direction = random.choice(["UP", "DOWN", "LEFT", "RIGHT"]) def move(self):
x, y = self.body[0] if self.direction == "UP":
y -= CELL_SIZE elif self.direction == "DOWN":
y += CELL_SIZE elif self.direction == "LEFT":
x -= CELL_SIZE elif self.direction == "RIGHT":
x += CELL_SIZE
self.body.insert(0, (x, y))
self.body.pop() def change_direction(self, direction): if direction == "UP" and self.direction != "DOWN":
self.direction = direction elif direction == "DOWN" and self.direction != "UP":
self.direction = direction elif direction == "LEFT" and self.direction != "RIGHT":
self.direction = direction elif direction == "RIGHT" and self.direction != "LEFT":
self.direction = direction def draw(self): for x, y in self.body:
pygame.draw.rect(window, GREEN, (x, y, CELL_SIZE, CELL_SIZE)) def check_collision(self):
x, y = self.body[0] if x < 0 or x >= WINDOW_WIDTH or y < 0 or y >= WINDOW_HEIGHT: return True for body_part in self.body[1:]: if body_part == (x, y): return True return False def eat_food(self, food): if self.body[0] == food.position:
self.body.append((food.position[0], food.position[1]))
food.generate() # 食物类 class Food: def __init__(self):
self.position = (
random.randint(0, (WINDOW_WIDTH-CELL_SIZE) // CELL_SIZE) * CELL_SIZE,
random.randint(0, (WINDOW_HEIGHT-CELL_SIZE) // CELL_SIZE) * CELL_SIZE
) def draw(self):
pygame.draw.rect(window, RED, (self.position[0], self.position[1], CELL_SIZE, CELL_SIZE)) def generate(self):
self.position = (
random.randint(0, (WINDOW_WIDTH-CELL_SIZE) // CELL_SIZE) * CELL_SIZE,
random.randint(0, (WINDOW_HEIGHT-CELL_SIZE) // CELL_SIZE) * CELL_SIZE
)
snake = Snake()
food = Food()
clock = pygame.time.Clock() # 游戏主循环 running = True while running: for event in pygame.event.get(): if event.type == pygame.QUIT:
running = False elif event.type == pygame.KEYDOWN: if event.key == pygame.K_UP:
snake.change_direction("UP") elif event.key == pygame.K_DOWN:
snake.change_direction("DOWN") elif event.key == pygame.K_LEFT:
snake.change_direction("LEFT") elif event.key == pygame.K_RIGHT:
snake.change_direction("RIGHT")
snake.move() if snake.check_collision():
running = False snake.eat_food(food)
window.fill(BLACK)
snake.draw()
food.draw()
pygame.display.flip()
clock.tick(10)
pygame.quit()
这段代码使用了 Pygame 库来实现游戏窗口和图形的绘制,以及捕获键盘事件。贪吃蛇的移动、吃食物和碰撞检测等逻辑也在代码中实现。你可以将代码复制到 Python 环境中执行,就可以玩这个简单的贪吃蛇游戏了。
