python实现吃苹果小游戏
本文实例为大家分享了python实现吃苹果小游戏的具体代码，供大家参考，具体内容如下
1.公共类模块
importpygame

def_setx(self,value):self.rect.x=value
def_sety(self,value):self.rect.y=value
"""
描述
property()函数的作用是在新式类中返回属性值。
语法
以下是property()方法的语法:
classproperty([fget[,fset[,fdel[,doc]]]])
参数
fget--获取属性值的函数
fset--设置属性值的函数
fdel--删除属性值函数
doc--属性描述信息
返回值
返回新式类属性。

2.首先生成随机苹果，然后监听键盘移动，播放动画。精灵和苹果碰撞检测，检测是吃掉苹果
