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
var nc = $"/root/nc" # new Godot 3 syntax
To add an object as observer
- 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:
- 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
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
Every observer of notificationName will execute its action.
