Events

• addEventHandler replaced with decorator event

@g2o.event('onInit')
def evtInitFirst(**kwargs):
    print('Hello')
    
@g2o.event('onInit', 100)       # '100' is priority
def evtInitSecond(**kwargs):
    print('World')

---

• Positional arguments replaced with keyword arguments (see names of all keywords on the each event page)

@g2o.event('onPlayerChangeColor')
def evtColor(**kwargs):
    playerid = kwargs['playerid']
    r = kwargs['r']
    b = kwargs['b']

---

• callEvent now also requires to pass keyword arguments instead of positional arguments

@g2o.event('MyTestEvent')
def testEvt(**kwargs):
    print(kwargs)
    
g2o.callEvent('MyTestEvent', name = 'aurumvorax', id = 15)
# OR
g2o.callEvent('MyTestEvent', {'name': 'aurumvorax', 'id': 15})
# OR
args = {'name': 'aurumvorax', 'id': 15}
g2o.callEvent('MyTestEvent', args)

---

• cancelEvent replaced with returning False inside the handler ^{(you don't need to explicitly return True if you don't want to cancel the event)}

@g2o.event('onPlayerTakeItem')
def evtTake(**kwargs):
    return False

---

• isEventCancelled replaced with built-in function property cancelled, alongside with the eventName (if you need it for some reason)

@g2o.event('onPlayerDropItem')
def evtDrop(**kwargs):
    print(evtDrop.cancelled)
    print(evtDrop.eventName)
