Making new nodes can be easy or hard, depending on the planned node. Some will just require this guide, some will benefit from being introduced with an entire plugin. This guide will assume the former.
Write this code:
tool
extends Node
class_name TestNode
export var message = "Hello world!" setget set_message
func _ready():
print(message)
func set_message(value):
if value and value is String:
message = value
The setget tells the engine to run set_message whenever you try to change message. In this particular example, you cannot empty it. Because of the tool
The class_name tells the engine to add the script to the add node popup, add it to the auto-correction list and to allow you to instance it with TestNode.new().
