有人帮我看看这个吗？
这是一个石头剪刀布的小游戏；
但是结果和实际不符合 比如我出剪刀 机器人出布 会显示平手或输等等
中间有很多是布局 其实核心就几句话
大家可以帮我看看吗qaq

你win的代码写错了
return x，y，3是想干什么？
不是1代表你赢，2代表电脑赢，3代表平手吗
x是个变量，你咋知道会return个什么玩意，那不变成出锤子就赢，出布就输，这跟出什么不应该有关系，只应该和x与y的关系有关系才对
其实就这样就对了：
if(x==y+1 || x+2==y)
{
return 1;//你赢
}
else if(x==y)
{
return 3;//平手
}
else
{
return 2;//电脑赢
}
归根结底，是你没理解return的到底是个什么东西
你把x和y理解成玩家和电脑两个对象，return谁就是谁赢
但是x和y并不是对象，只不过是锤子剪刀布的其中一种状态
还有，x==1&&y==3,x==3&&y==1，两种截然相反的状态，都返回3，你是认真的吗，这不管把return理解成什么，都说不过去吧
