has anyone written code to detect if the user presses the back button?

(the arrow facing left, not the home button)

c.k.	(Posted 2013) [#2]

During OnUpdate(), do this:

[monkeycode]
If KeyHit(KEY_ESCAPE) Then
' back arrow was hit
EndIf
[/monkeycode]

It should be noted that the back button on Windows phone will only respond to JoyHit( JOY_BACK ) so I tend to use both.

If KeyHit(KEY_ESCAPE) Then
' back arrow was hit
EndIf

on 4.1/4.2 sleeps the app it seems and returns the user to the home screen as if they pressed the home button, happens on a Nexus 7 (4.2) and S3mini (4.1), doesn't matter what I do inside the IF.

oh wait there is the new OnClose and OnBack stuff. I'll look at that

Yes, using onBack works great now!

So, there's also ExitApp which is called by default when OnBack is called.

So new to monkey... so how would you override the code. Would something like this work?

if (OnBack()) 
   // do my stuff
   ExitApp

....

function OnBack:void()
   // add code to ask user if he really wants to quit...
   ExitApp

(and I'm using V69, waiting for V70 release.. :))
