Error when trying to change the "scale" property in the "Panel" node with a tween

Boltz

I run into an error when I try to change the scale property of the panel node. I am trying to use the panel as a health bar, but whenever I run the code to animate the change in health using a tween, an error returns when trying to change the scale of the health panel saying that the "scale" property doesn't exist.

Here is the error:

Here is my code:

It says the Object named Panel does not have property named scale. Which is correct: https://docs.godotengine.org/en/stable/classes/class_panel.html

Panel class does extend however the Control class which has a property named rect_scale: https://docs.godotengine.org/en/stable/classes/class_control.html#class-control-property-rect-scale

Perhaps you meant to use that?

Using rect_scale instead of scale makes the code no longer show errors, but for some reason when I embedded print($Panel.rect_scale) into my code, it shows that the value of rect_scale never changes

Okay, just found the problem, I actually have to start the tween for the tween to work with $Tween.start(). :|

The rect_scale property is affected by the set_scale method. See the link to docs I provided for the property.

edit: but from the error alone I concluded that it just needed the property name, I guess if .start on the tween works now then that conclusion was right, I guess.
