Simply by setting the actorList = [] all the objects in the actorlist
will be destroyed, along with all references to objects stored
in properties of them, if any. You don't need to take each object
off the list to get it destroyed. If you do, then you need to destroy
the new reference you have created, so there's no advantage:
For example:
obj5 = (the actorList).[5]
the actorList = []
obj5 still lives here, so you have to set obj5 = void (or 0)
in order to destroy it.
If you want to destroy a particular object in the actorList
and keep the others, things may become a little more tricky
if you don't want to compact the actorList every time you
destroy an object. If you have four objects in the actorList
they will be called one at a time through the stepFrame
method of each of them: 1, 2, 3, 4.
Then, if you set (the actorList).[2] = void no error will
be issued since the object 2 hasn't any more a method
stepFrame to be called and the sequence of calls will be
1, 3, 4.
But if one of the remaining objects attempts to access a
property of a destroyed one, you get a "property not found"
error:
on mCalculateDistance me
ij = indexOfMeInActorList + 1
repeat with j = maxObjects down to ij
o = the actorList[j]
xox = x - o.x
yoy = y - o.y
distance = sqrt(xox * xox + yoy * yoy)
end repeat
....
end
When this code is in execution for the object 1, an error is
issued for j=2 since o = the actorList[j], is not an object and
doesn't have a prop x cause it was destroyed.
Circumstances may suggest the best use of actorList.
