Question

问候语，我刚刚开始学习脚本，并试图为学校项目制作记忆游戏。我自己能够解决大部分问题，但现在我偶然发现了一个我无法解决的错误：/

1180：在第80行调用可能未定义的方法数组功能setupGame() cardValues = new arrays();

arrays不是一个类，您可能想创建一个Array。

查看您的错误实际上告诉您需要知道的一切：

1180: Call to a possibly udefined method arrays on line 80

说你试图在第80行调用一个名为arrays的不存在的方法。我不明白为什么人们担心编译器的错误和警告，他们的意思是帮助你，你只是了解英语。
如果你不理解错误，那么有错误代码，在谷歌上搜索错误代码，你会找到一个解决方案。：）
