🐍导语：
?我们都玩过贪吃蛇游戏，那你知道如何用Python来实现贪吃蛇游戏吗？
?
今天这期小编就给大家来演示一个游戏的编程实现：【贪吃蛇】！
想领取更多游戏完整源码跟Python学习资料点击这行字体即可
🐍游戏效果
🐍实现方法
1.导入依赖库
主要是导入游戏包：pygame包。
import sys
import random
import numpy as np
import pygame
from pygame.locals import *2.初始化变量和窗口
1）初始化变量
2）初始化窗口
def initial():
global snake_speed_clock,Display,Display_font,Direction,snake_num,Score
global Cell_Size,Window_Width,Window_Height,Dark,Red,Green,Yellow,Black
global snake_food,Snake_speed
Cell_Size=20
Window_Width = 1000
Window_Height = 700
Dark = (80, 80, 80)
Red = (255, 0, 0)
Green = (0, 255, 0)
Yellow = (255, 255, 0)
Black = (0, 0, 0)
Snake_speed = 16
pygame.init()
snake_speed_clock = pygame.time.Clock()
Display = pygame.display.set_mode((Window_Width, Window_Height))
pygame.display.set_caption('Snake-Play')
Display_font = pygame.font.Font('freesansbold.ttf', 20)
Score=0
Direction = 'RIGHT'
snake_num = []
for i in range(16):
snake_num.append({'x': i,'y': 20})
draw_grid()
snake_food=make_food(snake_num)
draw_food(snake_food)
draw_snake(snake_num)
pygame.display.update()3.循环检测按键事件执行并刷新窗口
1）恢复窗口背景
Display.fill(Black)2）检测按键事件并执行运动
def run_direction():
global Direction,snake_num,snake_food,Score
for event in pygame.event.get():
if event.type == QUIT|K_ESCAPE:
terminate()
elif event.type == K_ESCAPE:
terminate()
elif event.type == KEYDOWN:
Direction=get_direction(event.key)
if Direction == 'RIGHT':
if snake_num[len(snake_num)-1]==snake_food:
snake_num.append(snake_food)
snake_food=make_food(snake_num)
Score=Score+10
else:
X=snake_num[len(snake_num)-1]['x']+1
Y=snake_num[len(snake_num)-1]['y']
c={'x': X,'y': Y}
m=snake_num[1:]
m.append(c)
snake_num=m
if Direction == 'LEFT':
if snake_num[len(snake_num)-1]==snake_food:
snake_num.append(snake_food)
snake_food=make_food(snake_num)
Score=Score+10
else:
X=snake_num[len(snake_num)-1]['x']-1
Y=snake_num[len(snake_num)-1]['y']
c={'x': X,'y': Y}
m=snake_num[1:]
m.append(c)
snake_num=m
if Direction == 'UP':
if snake_num[len(snake_num)-1]==snake_food:
snake_num.append(snake_food)
snake_food=make_food(snake_num)
Score=Score+10
else:
X=snake_num[len(snake_num)-1]['x']
Y=snake_num[len(snake_num)-1]['y']-1
c={'x': X,'y': Y}
m=snake_num[1:]
m.append(c)
snake_num=m
if Direction == 'DOWN':
if snake_num[len(snake_num)-1]==snake_food:
snake_num.append(snake_food)
snake_food=make_food(snake_num)
Score=Score+10
else:
X=snake_num[len(snake_num)-1]['x']
Y=snake_num[len(snake_num)-1]['y']+1
c={'x': X,'y': Y}
m=snake_num[1:]
m.append(c)
snake_num=m3）画贪吃蛇
def draw_snake(snake_num):
for i in range(len(snake_num)):
x = snake_num[i]['x'] * Cell_Size
y = snake_num[i]['y'] * Cell_Size
appleRect = pygame.Rect(x, y, Cell_Size, Cell_Size)
pygame.draw.rect(Display, Green, appleRect)
draw_grid()
pygame.display.update()4）刷新窗口
pygame.display.update()
snake_speed_clock.tick(Snake_speed)4.若退出关闭游戏
若有退出事件，则执行关闭游戏操作！
def terminate():
pygame.quit()
sys.exit()
