這篇文章主要為大家詳細(xì)介紹了python貪吃蛇游戲代碼，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了python貪吃蛇游戲的具體代碼，供大家參考，具體內(nèi)容如下

貪吃蛇游戲截圖：

首先安裝pygame，可以使用pip安裝pygame：

pip install pygame

運(yùn)行以下代碼即可：

#!/usr/bin/env python
import pygame,sys,time,random
from pygame.locals import *
# 定義顏色變量
redColour = pygame.Color(255,0,0)
blackColour = pygame.Color(0,0,0)
whiteColour = pygame.Color(255,255,255)
greyColour = pygame.Color(150,150,150)

# 定義gameOver函數(shù)
def gameOver(playSurface):
 gameOverFont = pygame.font.Font('arial.ttf',72)
 gameOverSurf = gameOverFont.render('Game Over', True, greyColour)
 gameOverRect = gameOverSurf.get_rect()
 gameOverRect.midtop = (320, 10)
 playSurface.blit(gameOverSurf, gameOverRect)
 pygame.display.flip()
 time.sleep(5)
 pygame.quit()
 sys.exit()

# 定義main函數(shù)
def main():
 # 初始化pygame
 pygame.init()
 fpsClock = pygame.time.Clock()
 # 創(chuàng)建pygame顯示層
 playSurface = pygame.display.set_mode((640,480))
 pygame.display.set_caption('Raspberry Snake')

 # 初始化變量
 snakePosition = [100,100]
 snakeSegments = [[100,100],[80,100],[60,100]]
 raspberryPosition = [300,300]
 raspberrySpawned = 1
 direction = 'right'
 changeDirection = direction
 while True:
 # 檢測(cè)例如按鍵等pygame事件
 for event in pygame.event.get():
 if event.type == QUIT:
 pygame.quit()
 sys.exit()
 elif event.type == KEYDOWN:
 # 判斷鍵盤事件
 if event.key == K_RIGHT or event.key == ord('d'):
 changeDirection = 'right'
 if event.key == K_LEFT or event.key == ord('a'):
 changeDirection = 'left'
 if event.key == K_UP or event.key == ord('w'):
 changeDirection = 'up'
 if event.key == K_DOWN or event.key == ord('s'):
 changeDirection = 'down'
 if event.key == K_ESCAPE:
 pygame.event.post(pygame.event.Event(QUIT))
 # 判斷是否輸入了反方向
 if changeDirection == 'right' and not direction == 'left':
 direction = changeDirection
 if changeDirection == 'left' and not direction == 'right':
 direction = changeDirection
 if changeDirection == 'up' and not direction == 'down':
 direction = changeDirection
 if changeDirection == 'down' and not direction == 'up':
 direction = changeDirection
 # 根據(jù)方向移動(dòng)蛇頭的坐標(biāo)
 if direction == 'right':
 snakePosition[0] += 20
 if direction == 'left':
 snakePosition[0] -= 20
 if direction == 'up':
 snakePosition[1] -= 20
 if direction == 'down':
 snakePosition[1] += 20
 # 增加蛇的長(zhǎng)度
 snakeSegments.insert(0,list(snakePosition))
 # 判斷是否吃掉了樹莓
 if snakePosition[0] == raspberryPosition[0] and snakePosition[1] == raspberryPosition[1]:
 raspberrySpawned = 0
 else:
 snakeSegments.pop()
 # 如果吃掉樹莓，則重新生成樹莓
 if raspberrySpawned == 0:
 x = random.randrange(1,32)
 y = random.randrange(1,24)
 raspberryPosition = [int(x*20),int(y*20)]
 raspberrySpawned = 1
 # 繪制pygame顯示層
 playSurface.fill(blackColour)
 for position in snakeSegments:
 pygame.draw.rect(playSurface,whiteColour,Rect(position[0],position[1],20,20))
 pygame.draw.rect(playSurface,redColour,Rect(raspberryPosition[0], raspberryPosition[1],20,20))

 # 刷新pygame顯示層
 pygame.display.flip()
 # 判斷是否死亡
 if snakePosition[0] > 620 or snakePosition[0] < 0:
 gameOver(playSurface)
 if snakePosition[1] > 460 or snakePosition[1] < 0:
 for snakeBody in snakeSegments[1:]:
 if snakePosition[0] == snakeBody[0] and snakePosition[1] == snakeBody[1]:
 gameOver(playSurface)
 # 控制游戲速度
 fpsClock.tick(5)

if __name__ == "__main__":
 main()

操作方法：

上下左右鍵或wsad鍵控制

ESC鍵退出游戲
