Hello THE HELIX,

first a few things I see reviewing your code.

  1. Your Label needs a reference to the Area2D in order to work properly with signals. The connection call in the _ready() function of your Label should be something like this:
    reference_to_area2D.connect("life_changed", self, "_on_life_changed")

You will allways emiting a signal from where you declare it. So your Area2D declares a signal and it want to send this signal to the Label. So the Area2D needs to be conntected to the Label. Think about it, or read the docs about Signals :-).

You can get the reference of a node with the get_node() method. For example in your scene: var life_2 = get_node("/root/???/Control/Life_2"). (“???”, because I cant identify the top node on your uploaded picture)

I would suggest you to look at the docs. There is a nice little intro for scripting a scene.

  1. Your Label needs the corresponding function you are trying to connected to: "_on_life_changed"
    put it in the script of the Label like you do with _on_body_entered() in the Area2D script. Otherwise, it will never be called.

1 : how to make the label show the life value decreasing to 0

You can access the Label’s property text and manipulate it.

A good way is to send the current life points as variable within your signal, like emit_signal("life_changed", life). Make sure your signal declaration looks like something like this signal life_changed(your_variable)

So, lets say you have a function _on_life_changed(your_variable) in your Label’s script. Then you can easily manipulate the text with set_text(str(your_variable)).
str() will convert your number into a string :slight_smile:

Sorry, i do not understand what you are trying to archieve :frowning:
