Application.wantsToQuit

Description

Unity raises this event when the player application wants to quit.

Add an event handler to this event to receive a notification that application is attempting to quit.

When this event is raised the quit process has started but can be cancelled. This means the player is not guaranteed to quit. For a guaranteed quit event take a look at Application.quitting.

Return true and the quit process will continue. Return false and the quit process will cancel.

Note: The return value of this event is ignored when exiting play mode in the editor. IMPORTANT: The return has no effect on iPhone. Application can not prevent termination under iPhone OS.

using UnityEngine;

public class PlayerWantsToQuitExample
{
    static bool WantsToQuit()
    {
        Debug.Log("Player prevented from quitting.");
        return false;
    }

    [RuntimeInitializeOnLoadMethod]
    static void RunOnStart()
    {
        Application.wantsToQuit += WantsToQuit;
    }
}
