Dear Carla,
in class 'CenterAgent' inherited from 'Agent' the
'act' method is implemented to send 'rest' action.
But of course, you can override it in your
'FireStation' class and put your code in there.
there's also another solution:
you can add a new method - let's call it 'hearDecide' -
to class 'Agent' like this:
protected abstract void hearDecide();
and modify the method 'run' of class 'Agent' as
follows:
.
.
.
if (data instanceof KaSense) {
// add this line here:
hearDecide();
KaSense sense = (KaSense) data;
.
.
.
Now as you see, when we receive a 'KA_SENSE'
packet, we are sure that the new cycle is
beginning and as a result we have received
all the messages we should have heard. So,
we call 'hearDecide' to notify the decision
layer about this event. If you implement
'hearDecide', you can use it instead of 'act'
for this purpose.
