say I have a gui component and the layout like below:
HBoxContainer:
-TextureProgress

I have script for the HBoxContainer and export a value called hp
and I want to make the HBoxContainer in tool mode so that when I change the hp
I can see the textureprogress reflect the hp value in editor.

However I don’t know how to do it.
Can anyone help me?
thanks

The editor triggers setters for variables when you change them. You can therefore make a setter that updates the TextureProgress.

You could of course also use the _process function and check if the value had changed on each update, but you may have to restart the editor for the changes in the code to take effect.
