OnExitingPlayModeAttribute

Description

Marks a static method as a callback to be invoked when exiting Play mode.

Methods marked with this attribute are called when exiting Play mode. This happens:

• When stopping Play mode in the Editor.
• Before code reload in Play mode (Editor only).
• Before application quit (Player only).

Use this callback to:

• Save Play mode state.
• Clean up runtime resources.
• Prepare for Edit mode or code reload.

This is a method attribute that can only be applied to static methods with no parameters and return type void.

Important: Due to differences in the way different platforms handle closing or navigating away from a running application, [OnExitingPlayMode] is subject to the same platform-specific limitations in built Players as MonoBehaviour.OnApplicationQuit. For more information, refer to the description for MonoBehaviour.OnApplicationQuit.
