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:
I have created a file res://addons/rgCheckBox/custom_node.gd:
add_custom_type("rgCheckBox", "CheckBox", preload("rgCheckBox.gd"), preload("icon.png"))
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
