[OnInspectorInit] 特性¶

The OnInspectorInit attribute takes in an action string as an argument (typically the name of a method to be invoked, or an expression to be executed), and executes that action when the property's drawers are initialized in the inspector. Initialization will happen at least once during the first drawn frame of any given property, but may also happen several times later, most often when the type of a polymorphic property changes and it refreshes its drawer setup and recreates all its children.
