c# –Unity在Play上崩溃,很可能是无限循环,但找不到问题

概述谢谢阅读.我目前正在使用C#在Unity中构建一个小型存储卡游戏.我已经完成了代码的主要部分但是当我按某个场景上的播放按钮时,Unity会冻结.我相信这是由于一个无限的While循环,但我找不到问题.我真的很感激任何人都可以提供帮助.我将在下面留下我的代码.提前致谢.usingSystem.C

我相信问题在于while(！test),但我不知道为什么测试永远不会成真.

感谢您的阅读,如果有帮助,我会发布一个指向github存储库的链接.

解决方法:

您的deck数组中至少有一张卡,其中_setUp设置为true,这将使其进入无限循环.

它进入无限循环的原因是因为它将所有可用的_setUp设置为true,并且它将继续寻找设置为false的_setUp并且它永远不会找到任何.

你需要至少26个具有_setUp为false的对象的原因是因为在嵌套的for循环中你循环13次然后你做了两次,总共有26个循环.所以你需要至少26个对象.

你可以做些什么来确保它们都是假的是在进入for循环之前将它们全部设置为false

for(int i = 0; i < deck.Length; i++){    deck[i].GetComponent<Card>().SetUp = false;}
