I have a character with hp and a progress bar to display the hp.

Is there the best way to bind the hp data to progress bar value?

Currently I just update the progress bar value whenever my character hp is changed.
But I think it is not good as the character is coupled with the UI element. Therefore I want a way to bind data between the character and the progress bar.

Thank you.

Are you working in 2d or 3d ?
What is wrong with " the character is coupled with the UI element" ?

in 3D, but what is the matter?
The problem is the character is not flexible and may be hard to manage if it coupled with UI

You can do it with groups.

First you have to add node to a group: https://forum.godotengine.org/10513/how-to-add-nodes-to-a-group. Then you can get from tree array of nodes of that group.

Simple example:

var nodes_update = get_tree().get_nodes_in_group("character_hud")
for i in range(nodes_update.size()):
	nodes_update[i].your_function(data)
