Hi Richie,
Andreas is wright. In principle you have to write your own behavior
class. I did this some time ago, but I am not able to place the code
here. I just summarize what you
have to do in a few words.
In my environment I am moving the viewing platform position of the
viewing
platform. The behavior - before terminating the processStimulus() -
should check
(somehow) your constraint to the platform position and, if the
constraint is violated, change the position to a valid state.
Thats it, basically.
I have built my own behavior architecture and therefore my behaviors are
"contrainable"; meaning that you can add constraining instances (having
a common
interface) to every behavior.
After the processStimulus(..) has reached it's end, I check all
constraints attached to
the specific behavior.
I implemented a plane constraint that restricts the platfrom position to
one halfspace.
Then I easily stuck some plane constrains together on my navigation
behavior and the user was not able to leave the plane defined volume.
Thinking shortly over your approach:
its possible to de-/activate behaviors by their activation bounds, but
you would need
many different behavior instances, that are restricted to move in one
direction.
Lets say a NavigateForward and a NavigateBackward behavior. Then you
would
be restricted to the volume where the activation bounds overlap.
