作者：側耳听偑
这篇文章主要为大家详细介绍了python实现简单贪吃蛇小游戏，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文实例为大家分享了python实现简单贪吃蛇的具体代码，供大家参考，具体内容如下
1. 导入游戏库
import pgzrun import random
2.游戏初始化
# 窗口大小 WIDTH = 600 HEIGHT = 480 # 贪吃蛇 bodys = [ [100,100],[80,100], [60,100], [40,100], [20,100]] head = [100,100] d = 'right' # 食物 food = [290,290] # 得分 score=0
3.游戏窗口绘制
def draw():
#清空屏幕
screen.clear()
# 绘制网格
for i in range(1,24):
screen.draw.line((0,i*20),(600,i*20),'gray')
for i in range(1,30):
screen.draw.line((i*20,0),(i*20,480),'gray')
#绘制蛇
for body in bodys:
rect = Rect(body,(20,20))
screen.draw.filled_rect(rect,(0,0,255))
inner = [body[0]+2,body[1]+2]
rect = Rect(inner, (15, 15),center='center')
screen.draw.filled_rect(rect, (0, 0, 180))
# 绘制头
rect = Rect(head, (20, 20))
screen.draw.filled_rect(rect, (0, 200,0))
inner = [head[0] + 2, head[1] + 2]
rect = Rect(inner, (15, 15))
screen.draw.filled_rect(rect, (0, 255, 12))
# 绘制食物
screen.draw.filled_circle(food,10, '#ffddee')
# 绘制得分
screen.draw.text('score:'+str(score),(20, 20), color="orange",fontsize=30)4.蛇的移动功能
def run(): global food,d,head,bodys,score # 新增一个格子的身体 if d=='right': head[0] += 20 elif d=='left': head[0] -= 20 elif d=='up': head[1] -= 20 else: head[1] += 20 bodys.insert(0,list(head)) if head[0] == food[0]-10 and head[1] == food[1] - 10: food = [random.randint(1,30)*20-10,random.randint(1,20)*20-10] score+=1 if score>3: clock.unschedule(run) clock.schedule_interval(run, 0.1) else: bodys.pop() # 撞墙后重新开始 if head[0]<0 or head[0]>580 or head[1]<0 or head[1]>480 or head in bodys[1:]: # 蛇回到初始位置 bodys = [[100, 100], [80, 100], [60, 100], [40, 100], [20, 100]] head = [100, 100] # 方向向右 d = 'right' # 得分清零 score=0 clock.unschedule(run) clock.schedule_interval(run, 0.3)
5.按键控制蛇的行走方向
# 按键控制蛇的行走方向 def on_key_down(key): global d # 改变方向 if key == keys.DOWN and d != 'up': d = 'down' if key == keys.UP and d != 'down': d = 'up' if key == keys.LEFT and d != 'right': d = 'left' if key == keys.RIGHT and d != 'left': d = 'right'
6.启动游戏
# 定时设置
clock.schedule_interval(run, 0.3)
# 播放音乐
music.play('music.mp3')
# 启动游戏
