How do I manage events in Monkey? For instance, I had been dabbling in Corona SDK and it lets me poll objects to see if they've experienced an event (such as a touch).

setEventBehavior( MyObject, "touch", MyTouchFunctionForMyObject )

Is that something that might eventually be added to Monkey, or is it roll-your-own?

I've been using Diddy significantly for my first minor project (solely to get used to Monkey). Does it have an events system of which I'm not aware? :)

MyDiddyObject.onTouch( RunThisFunctionWhenTouched )

Unfortunately since Monkey does not support function pointers (or any kind of pointer), making an event-based system would prove tricky. I suppose I could take a look at it, but I'm not making any promises. :)

Hi,

Definitely roll-your-own right now - there's no GUI or retained mode sprite system in Mojo.

You can use objects or interfaces for functions pointers, eg:

'function
Interface TouchHandler

   Method OnTouchDown( finger )

End

Class Gadget

   ''function pointer'
   Field touchHandler:TouchHandler

   Method SetTouchHandler( handler:TouchHandler )

End

Class Actor Implements TouchHandler

   Method OnTouchDown( finger )
       'blah!
   End

End
