Not exactly.
We need to make the other side to percieve the effects of the actions performed
at this side of the portal.

For example:
I cast fireball inside of the house, that is 4x4 meters. The fireball range is
30 meters of radius ( example only ), so my stupid ( means very simple )
solution is to notify all the objects inside the range of the fireball about the
action, and obviously apply effect to them, this mean ALL objects, inside and
outside of the building.
As you should realisice this solution is not correct. ( And I don't think it
would be fast enough ).

A worse problem has just appeared. SEE!

The dot is the street and the O are the buildings ( that are a different map,
that is accessed through a portal ).
So imagine that I am inside of building 1 and that I cast fireball with the same
range and sizes than above, so the stupid solution will make all the objects in
the outside area to be included, but we are missing objects inside Building 2,
that are also in the range of the fireball and so that should be also affected.

But if we are brave and we add a recursive portal exploration to thing, the time
needed to compute the area of effect will be so big that it is not going to be
useful.

( Now I start to understand why Baldur's Gate didn't have this ON ).

Would u mind to explain it?
k, I guess. You want to mean that Object is at both side of the portal, isn't
it? It can't happens.

Sound good.
Anyway in my idea, portals are only an object ( that physically exist ) that
process USE actions and make the actor to be moved to the other side of the
portal.
To manage the channeling, I have though that if there is an Portal object on the
range of the action, it should then be checked all the objects avaliable at the
other side of the portal.
