Timeline of events about morse

[PierrickKoch]

One way to achieve it:

• allow the user to specify in a builder script a class or function that will be called by the game engine in the main loop, with access to the MORSE internals (to be define -> which internals) and the amont of seconds since the start.

I've started looking at implementing such events by using the testing framework, but I have faced some issues and have had no time to work again on it for a while... The idea was that an event is a guard (just as in a test) with an effect. I put here some code I tried some weeks ago (but I can't remeber what was the issue with it):

class TestBloque:
    def __init__(self, pos=[110, -38], th=5):
        self.morse = pymorse.Morse("localhost", 4000)
        self.gps = self.morse.stream('GPS')
        self.pos_bloque = pos
        self.pos_threshold = th
        self.gps.subscribe(self.event_at_pos)

    def event_at_pos(self, data):
        dist = math.sqrt( math.pow(data['x'] - self.pos_bloque[0], 2) 
                          + math.pow(data['y'] - self.pos_bloque[1], 2))
        if (dist < self.pos_threshold) :
            print("Send event 'bloque'")
            send_event("bloque", "/super_nav/ctrl/in")
            self.gps.unsubscribe(self.event_at_pos)

TestBloque(pos=[114, -42], th=2)

If going this way for managing (timed) events seems a good solution for everyone, I can work again on it in January, and then propose an events API on top on testing.

To be honest, it is not very clear to me... Besides, I do not see the "timed" aspect...?

[lesire]

I used the testing API and subscribed a new "test" for the GPS component. This test is actually an event: when the GPS position is close to 'pos', it sends the "bloque" string on a Yarp port (external to MORSE).
I think extending it to have a condition like "when time is close to 't'", and an effect like "add a cube in the scene at (x,y,z)" would not be too complicated!
