How to make a timer to run if app is suspended

For my type of game, I need to continue run a timer (to refill the player energy) even if this one suspended the application from the iPad or Android Hoem button.

I am using the small cDeltaTimer class, but the update is done in OnUpdate.

How should I handle this?

Well, you can check Millisecs() when an update finally occurs, and update the energy then based on the total time elapsed I.e. if the last update was 15 minutes ago, give a full 15 minutes of energy, even if nothing else gets 15 minutes worth of updates.

Well, I made this test:

	Method OnResume:Int()		
		Print "resumed @ " + Millisecs()'
	End
	
	Method OnSuspend:Int()
		timerSuspended = Millisecs()
		Print "suspend @ " + timerSuspended
	End

but the Millisescs() is returning the actual app time so when i come back is still the same time as when I leave..

Calculate time to full refill, store it and check time to up in update loop.

@nikoniko:
Lets say the time to refill is 60 seconds. When the users suspends the application I store this value, right?

Second time when he enters, how do I know how many seconds pasts since last check?

GetDate function in mojo.app. Is that what you are looking for?

I didn't realise that Millisecs() stopped when the app was suspended. But as Ferdi says, GetDate() is therefore the answer.

Yeah! GetDate()

Thanks guys :D

Love you all!

Just a warning in GLFW the millisecs part is not working in GetDate. It works in HTML5.

Thanks for sharing that Ferdi, but I only need this for iOS and Android.
