python小游戏 太空人入侵

步骤如下

• 创建背景
• 创建玩家 玩家动起来
• 创建敌人 敌人动起来
• 创建，发射子弹
• 添加分数
• 判定游戏结束
• 载入音乐

一个简单的小游戏，没有用太多的库
效果：




代码如下：

import turtle
import random
import simpleaudio as sa
#载入音乐
laser = sa.WaveObject.from_wave_file('./img/laser.wav')
exp = sa.WaveObject.from_wave_file('./img/explosion.wav')
# 设置背景
game = turtle.Screen()
game.setup(700,700)
game.title('太空人入侵')
game.bgpic('./img/bg.gif')

# 创建玩家
turtle.addshape('./img/player.gif')

player.ht()
player.speed(0)
player.up()
player.shape('./img/player.gif')
player.setpos(0,-300)
player.st()

# 添加分数
score = 0

pen.color('white')

pen.up()
pen.ht()
