thanks, this is going forward. :)
but only the last created object should be moved to a free position. in your example, sometimes already existing objects move too.
this is the main problem: how to pick the last instance and check against the remaining.
this is the simplest solution i found trough a temp object.
but couldn't this be made without a dummy object?
or is there any way to "pick all instances but n'th" ?
many thanks :)
