This just came up again yesterday, and I said, "We have had
discussions in the past here on Lingo-L about this. Many people
commented that they felt that it is OK to get the value of such a
property, but it is not OK to set such a value. Again, I am strongly
of the opinion that if you want to get the value of a property of an
object [or in you case, a behavior], you should have an "accessor"
method to do so. "
For more information about accessor methods, check out:
http://www.furrypants.com/loope (specifically chapter 4)
If, as you say, you already have behaviors that link themselves
dynamically to your objects, as part of the "linking" mechanism, they
could pass either their sprite number or a reference to themselves
(me). The receiving object can then store away this reference in a
property variable, and use it again when it wants to communicate with
the behavior. If you pass a sprite number, then you can communicate
back to the behavior using sendSprite. If you pass a behavior
reference, then you can communicate back to that behavior using
"call", or a standard object/method pair:
mGetSomeData.pReferenceToAppropriateBehaviorSentInEarlier.
Hope this helps,
Irv
