Play Games Turn-Based Multiplayer: lose game onApplicationQuit
Hi,
I'm currently developing an Android game with a turn based multiplayer system using googles Play Games Services.
What I want to do is to quit the game (aka call the TakeTurn method) when the user quits the app. Currently the player can just quit the game via the task manager and play his turn again until he has a good enough score. That's obviously not very good.
However, the onApplicationQuit method apparently doesn't get called if the game is closed in the task manager. Is there any other way to catch that event? Or can I configure Play Games in any such way?
Quitting the game in onApplicationPause is also no option because then the game would be lost, if the user just presses the task manager button, takes a call or clicks on an achievement popup.
Does anyone have any idea how I could do it?
Cheers
UPDATE: Okay, today OnApplicationQuit gets called even if closed in the task manager. Not sure why it didn't yesterday, I think I didn't change anything there. Nonetheless the game is not correctly finished because the game doesn't wait for the TakeTurn() callbacks (I think). TakeTurn() gets called, but then the app is closed directly. Is there a problem with my CancelQuit?
void OnApplicationQuit()
{
if (!bAllowQuitting)
{
StartCoroutine("DelayedQuit");
Application.CancelQuit();
}
}
IEnumerator DelayedQuit() {
while(bAllowQuitting)
{
yield return null;
}
Application.Quit();
}
UPDATE2: Ah... Apparently OnApplicationQuit gets called on a Samsung Galaxy Tab 4, but not on a S6 edge... Great -.-
@mooneye For each game, create a variable that tracks that the turn was started. Set turnStarted = true, and store it in persistent storage (preferences, sqlite, custom file) at the start of TakeTurn. Ideally, the contents of this should not be player readable otherwise rooted players can potentially modify it gain unfair advantage.
Now, when the app is closed via Task Manager or killed in the background you can check if the player had already started his turn and call TakeTurn during start up.
This way you can be sure that no one can cheat and replay the same turn.
