    }    
  ]
}

Note: you will receive events only from your drone

All Events

Because of at each tick is 1 second, your function could missed these events. So you should analyse first the situation and then acting one event.

event attribut is the type of event currently received. event value can be :

WAITING_FOR_COMMAND (the drone is waiting for a new command even if its operating)
MOVING (the drone is currently moving to its move destination set in the command)
MOVE_LOCATION_ERROR (if the move location you sent in command is not valid)

So for example if your drone is currently flying to a point you will receive at each tick an event "MOVING"

Managing parcels

droneInfo.parcels attribut contains parcels that you have already grabbed and that you should deliver.

availableParcelsForTeam attribut you will get all the parcels that your drone can get. There is currently two type parcel:

"type": "CLASSIC" Typical parcel when the drone grab one of those he will have to go to the destination to earn the point.

"type": "SPEED_BOOST" This one is special it will allow your drone to go faster ! For this one you don't need to deliver it.
