PrefabUtility.RecordPrefabInstancePropertyModifications

参数

描述

导致对预制实例进行的修改被记录。

请注意，启用预制实例记录更改的推荐方法是使用 SerializedProperty 和 SerializedObject。这使实例能够记录更改并自动将更改包含在撤消系统中。

在对预制实例进行修改后调用此方法以记录实例中的这些更改。如果不调用此方法，对实例进行的更改将会丢失。请注意，如果您未使用 SerializedProperty/SerializedObject，则无论是否调用此方法，对对象的更改都不会记录在撤消系统中。

// The following Editor script doubles the scale of the selected GameObject,
