显示全部楼层
首先要下载pyfame
代码:
- #!/usr/bin/env python
- import pygame,sys,time,random
- from pygame.locals import *
- # 定义颜色变量
- redColour = pygame.Color(255,0,0)
- blackColour = pygame.Color(0,0,0)
- whiteColour = pygame.Color(255,255,255)
- greyColour = pygame.Color(150,150,150)
- # 定义gameOver函数
- 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()
- # 定义main函数
- def main():
- # 初始化pygame
- pygame.init()
- fpsClock = pygame.time.Clock()
- # 创建pygame显示层
- playSurface = pygame.display.set_mode((640,480))
- pygame.display.set_caption('Raspberry Snake')
- # 初始化变量
- snakePosition = [100,100]
- snakeSegments = [[100,100],[80,100],[60,100]]
- raspberryPosition = [300,300]
- raspberrySpawned = 1
- direction = 'right'
- changeDirection = direction
- while True:
- # 检测例如按键等pygame事件
- for event in pygame.event.get():
- if event.type == QUIT:

- if direction == 'up':
- snakePosition[1] -= 20
- if direction == 'down':
- snakePosition[1] += 20
- # 增加蛇的长度
- snakeSegments.insert(0,list(snakePosition))
- # 判断是否吃掉了树莓
- if snakePosition[0] == raspberryPosition[0] and snakePosition[1] == raspberryPosition[1]:
- raspberrySpawned = 0
- else:
- snakeSegments.pop()
- # 如果吃掉树莓,则重新生成树莓
- if raspberrySpawned == 0:
- x = random.randrange(1,32)
- y = random.randrange(1,24)
- raspberryPosition = [int(x*20),int(y*20)]
- raspberrySpawned = 1
- # 绘制pygame显示层
- 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显示层
- pygame.display.flip()
- # 判断是否死亡
- 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)
- # 控制游戏速度
- fpsClock.tick(5)
- if __name__ == "__main__":
- main()
