Freeze game when app loses focus

BlitzMax Forums/MaxGUI Module/Freeze game when app loses focus

**EDIT**
Whoops, I meant to put this in the programming section. I'll repost in a few days in the right section if I don't get an answer.

I would like my game to freeze when it loses focus and resume when it gains focus. Could someone please push me in the right direction? I figure it would have to be through a windows dll of some sort - which I'm clueless on the whole OS side of things anyway.

Thanks!

You might try searching, because I would have sworn a few months ago, GfK posted some code for exactly that.

Hiya

I'm not sure how Gfk did it, but you can use PollEvent to return EVENT_APPRESUME and EVENT_APPSUSPEND appropriately.

Strict

Graphics 800,600

While Not KeyDown(KEY_ESCAPE)
	Cls
	
	Local id = PollEvent()
	If id = EVENT_APPSUSPEND Print "App suspended"
	If id = EVENT_APPRESUME Print "App resumed"

	Flip
Wend

You could also try something like...
If AppSuspended()
  pauseGame = True
else
  pauseGame = false
endif
...Which amounts to the same thing.
