Thanks John and Karl for the answers...
Reading my original email I realized I was not so clear in the question (
definitively I have to improve my English :-| ).
What I was looking for is a way to get a reference to *any* morph under.
The idea is to program a type of "garbage collector" that walk around the
world and take any morph on the world (the garbage) and carries it to
a "safe" place.
I mean something like this:
lookForGarbage
self walkAround. "walk randomly over the world"
(self morphUnder = World)
ifTrue:[
self morphUnder owner: self.
self pauseScript: #lookForGarbage.
self startScript: #carryTheGarbageToASafePlace].
I hope this time I explained my needs better than before.
Cheers,
Diego
