FSM with functions

[Maurice Mouw]

Hi,

I've been workin with SPADE for a few weeks now. I need to build several MAS for a school project. Most of examples given are pretty straight forward and based on those I've made serveral agents.
Since last week I started working on FSM. I want to build several agents working on this. Based on the example I've build the attached 'buildrad.py'. I was wondering if the current setup I used is possible. When i start the agent i get the following:

As you can see it won't transition to the second stage. In this case i would be pretty sure it should at least go to the second because the connection to the localhost on port 80 is possible. If i strip the code i used there it works fine.
I'm probaply missing somthing here.

#note i've been doing this and serveral other things for school in the last few days(yes also the weekend) and have slept about 4-5 hours a night#

Any help would be appreciated :-)

Dear Maurice,

here's a little fix, instead of addBehaviour, put:

        self.setDefaultBehaviour(b)

The problem is that the agent doesn't seem to use FSM behaviour as a default one for message receiving. All states automatically get the message from the FSM behaviour (they use its _receive method).

All the best,

M.

And sorry I forgot, you also need to fix the if-else in the first state, since you cannot get to the second behavior:

    class StateOne(spade.Behaviour.OneShotBehaviour):
        REMOTE_SERVER = "127.0.0.1"
        def _process(self):
            print ("This is State One...")
            msg = self._receive(block=True,timeout=1)
            self._exitcode = self.myAgent.TRANSITION_DEFAULT
            if msg:
                if "True" in msg.getContent():
                    self.myAgent.counter = self.myAgent.counter + 1
                if self.myAgent.counter > 2:
                        self._exitcode = self.myAgent.TRANSITION_TO_TWO
            else:
                time.sleep( 1 )

All the best,

M.
