Prevent Quit (Windows)
Is there a way to respond to (and perhaps cancel) a quit event when the user clicks the X button in the top right corner of a Unity-generated window? I want to ask "Are you sure you want to quit?" in order to prevent users from accidentally killing the game while clicking around.
Thanks for your time!
Just look for Application.CancelQuit and MonoBehaviour.OnApplicationQuit. Note: This will only work in standalone apps. iPhone or Webplayer just ignore this (at least CancelQuit).
@davidjsushil: did this work? I'm trying to confirm quiting to give the user a chance to save some things, but usually when OnApplicationQuit() is called, OnDestroy() already got rid of most objects I'd like to save.
First you would need pro to call native OS code Link. After that it would look somthing like this:
Application.Exit( );
if (MessageBox.Show("Really Quit?", "Exit", MessageBoxButtons.OKCancel) == DialogResult.OK)
{
Application.Exit();
}
Xylax, thanks for the response. I don't have a pro license (yet), so I can't explore the solution you suggested. I was hoping that perhaps Unity had built-in support for handling a quit event - a method that could be overridden or something. So, am I out of luck for now, then?
You could try locking the mouse inside the frame (http://forum.unity3d.com/threads/3427-Constrain-$$anonymous$$ouse-Cusor-While-Fullscreen-(Windows))
I don't see any need for a native code plugin and how you could intercept the quit - message "legally". The only way from a native code plugin to intercept the close message is to subclass the Unity window (which is more hacking than game-developing). Also what's Application.Exit? Are you thinking of a C# windows application? In Unity there's just an Application.Quit
@davidjsushil: Please search the docs first next time. Since all scripts / classes that can receive callbacks from Unity have to be derived from $$anonymous$$onoBehaviour, that should be the first thing to look up. Almost all possible callbacks are listed there.
Bunny, I wouldn't have posted without searching for a solution first. Thanks, though!
