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

Use the "overlaps" tile; a sample script, looked at in text mode, would look like this:

script1 self forward: 5. (self overlaps: Ellipse1) ~~ false ifTrue: [self beep: 'coyote']

Best,

John

Hi,

I'd like to get a reference to the morph under the given object. The same idea behind color-under but with a reference to a morph instead to a color.

Is it possible?

TIA,

Diego
