string JSON 格式的对象数据。
生成对象的 JSON 表示形式。
This is similar to JsonUtility.ToJson, but it supports any engine object. The output is similar to the properties exposed via the SerializedObject API, or as found in the YAML-serialized form of the object.
If the object contains fields with references to other Unity objects, those references are serialized by recording the asset guid and local file id for each reference. This string can be saved, then deserialized in another session of the Unity Editor, and the references are resolved correctly.
However only objects that are located in an non-scene asset file can be referenced. References to objects within a scene, including the same scene, will not be serialized.
