我正在RoR上构建一个tic-tac-toe游戏。此刻,整个电路板都已设置好,其下方有一个跟踪移动的表格。我被告知使用该模型来确定这样的事情,如果有一个胜利者(连续3个),一个领带(全板),等等。我以为我有它,但显然不是。不确定我在模型中使用players
方法做错了什么。

当我运行我目前拥有的东西时,游戏一直播放,直到我有一个三排(此时只进行0,1,2的测试作为测试),切换玩家并表现正常。在三连胜的时刻,它保持在当前播放器的任何位置,并且不会切换。它没有结束游戏,也没有给我闪光通知。只是坚持当前的球员。同样如果我尝试添加elsif试图进入另一个获胜位置组合。
我意识到这可能是初级水平的东西,但我似乎无法绕过它,到目前为止还没有找到任何有用的东西。而且,如果if
陈述路线不是正确的方法,我愿意采取另一种方式。我现在无法想到一种不同的方式。
非常感谢任何帮助。
答案 0 :(得分:1)
想出来。只需要使用winner?
在!players(0).blank? &&
方法中设置每个组合。使用players
之后的每个==
的相应编号。
是否会删除这个问题,但万一有人真的好奇答案,那就是。
