Usage

Notifications are sent to observers. Any object can be an observer. Notifications can be sent from anywhere in your code.

If you need to add an observer or send a notification, get the root object:

var nc = get_node("/root/nc") # if you named it nc in the autoload settings

OR

var nc = $"/root/nc" # new Godot 3 syntax

To add an object as observer

nc.add_observer(observer,notificationName,action)

• observer is the object added as an observer
• notificationName is the ID of the notification. It is a String.
• action is the name of a function that must be defined by the observer with 3 parameters:

func action(observer,notificationName,notificationData):

• notificationData can by of any type. You can make a dictionary and include every needed data in it. It is sent with the notification.

To remove an observer

nc.remove_observer(observer, notificationName)

you MUST remove an observer, at least when it leaves the scene. Example:

func _exit_tree():
    nc.remove_observer(self, notificationName)

To send a notification

nc.post_notification(notificationName,notificationData)

Every observer of notificationName will execute its action.
