Hello everyone!

I am trying to create custom CheckBox using this article https://docs.godotengine.org/ru/stable/tutorials/plugins/editor/making_plugins.html#about-plugins

I have created a file res://addons/rgCheckBox/rgCheckBox.gd:

extends CheckBox
class_name rgCheckBox

func _ready():

I have created a file res://addons/rgCheckBox/custom_node.gd:

extends EditorPlugin

func _enter_tree():
    add_custom_type("rgCheckBox", "CheckBox", preload("rgCheckBox.gd"), preload("icon.png"))

func _exit_tree():

The problems:
1) I can not see rgChechBox in Editor control list
2) When I try to enable this custom component in [Project] > [Project Settings...] > [Plugins] then I get the message

Unable to load addon script from path: 'res://addons/rgCheckBox/rgCheckBox.gd' Base type is not EditorPlugin.

As I understand in Godot script multiple inheritance is not supported (or is supported but I did not find this syntax) - so how can I inherit my custom component from EditorPlugin and standard UI component in the same time? Or what am I generally doing wrong?

Thanks in advance

In your plugin.cfg file change the line





To prevent the error in future name your config file as plugin.gd or a naming scheme like
