Ok, imagine the following case:
-- behavior used as a frame script or attached to a sprite
-- that needs to create and use a timeout object
property pTimeout
on beginSprite (me) -- me is *required* here
-- spawn the timeout object, give it an arbitrary name of "Denis
-- Demo", have it fire off every 50 milliseconds calling the
-- "doSomeStuff" handler found within this same behavior script
pTimeout = timeout("Denis Demo").new(50,#doSomeStuff,me)
end beginSprite
on endSprite
-- clear the timeout object
pTimeout.forget()
pTimeout = VOID
end endSprite
on doSomeStuff
-- insert your timeout code here
end doSomeStuff
In the case above the "target object that contains the #timeOutHandler" is the
behavior script itself, and that's where the "me" argument of the beginSprite handler
comes into play. The "me" refers to that instance of the script when it's birthed into
memory (to quote the script talking to you: "that timeout handler is in *me*"). If the
timeout handler you want to specify is in another instanced script then you'll have to
provide a reference to that birthed object instead of me:
pTimeout = timeout(...).new(50,#handler,ObjRef)
Where ObjRef can refer to a parent script object, another instanced behavior on a
different sprite, etc. You can use the same information above to create your timeout
object from within a movie script but have the timeout handler elsewhere (like in a
behavior), it's just a matter of using the correct instanced script reference as the
"target object".
Hope that helps.
