我的JSON编写器只从模拟中编写一个对象

Question

我正在尝试使用WriteData((函数以JSON格式保存场景中多个对象的信息。然而，我面临的问题是，我的作者只保存了构成我所在楼层的一个单元的初始坐标，而不是保存楼层的所有坐标。

我目前有带标签的预制件，我正在查找并存储到游戏对象数组中。然后使用foreach循环遍历每个游戏对象数组以获得相关信息，将其分配给我创建的可序列化类中的数据，然后将其附加到JSON文件中。在这个过程中，它还将数据保存为单独的JSON字符串，而不是级联字符串。

这是我第一次使用JSON/Unity的JSON实用程序，所以任何帮助都将不胜感激。

下面是我目前正在使用的脚本的相关部分。

由于BugFinder的提示，您需要包装数组，因为json实用程序不支持数组，请参阅：

https://answers.unity.com/questions/1123326/jsonutility-array-not-supported.html

因此，您可以循环浏览您的人类、机器人、目标、对象等，并将它们添加到n数组中，然后将数组封装到SaveData对象中。更多信息；
