Is there a way to detect when the game goes to background?

[FranCalvente]

Hi all! I’m interested in calculate every second that the game goes inactive, I already have solved the part when I exit the game, I just save the Date Time and when I open again the game… BUT, I don’t know how to tell the game to save the Date Time when it goes to the background (not terminating the game). Is it actually possible?

Hi there @FranCalvente !

As I read on this thread, it’s not possible yet

Test if Viewport is Minimized?

Hello, In my game I control the mouse position to be restricted to the window, if I minimize the game window, the mouse is still restricted to the bounds of the viewport. Is there a way in Blueprint to test if the Viewport is minimized or not? I know there is a function to set the focus to a viewport but I cannot seem to find a node that contains the words “active”, “focus”, “minimized” that achieves this task.

One thing you could do is maybe saving the DateTime in a file (or log) every X seconds or something like that

Another thing I read somewhere else, posted 2 alternatives

How to make a minimized UE4 application continue to run in the background or minimized?

Thanks! that second option you mention worked for me!

That’s how Lyra does it

// Listen for the event
FSlateApplication::Get().OnApplicationActivationStateChanged().AddUObject(this, &ThisClass::OnAppActivationStateChanged);

// Check whether it is minimized right now
FSlateApplication::IsInitialized() && !FSlateApplication::Get().IsActive()
