Make signal react to only one specific instance of many same instance

Maratonec

So I have player1 and player2. They are both the instance of the same scene just in different positions. Then I am creating Area2D in players code and emit a signal when the players entered it. The problem is I want to player1 to be able to interact only with Area2D that he created and player2 with areas that he created.

This is my signal connection code: checkArea.connect("body_entered", self, "on_check_entered")

Also, I am adding checkarea to players parent (Node without anything) so it doesn't move with the player.

So my questions is how to make each players instance interact only with its created Areas2D?

I don't fully understand what you're doing. But when connecting a signal, you can define a parameter array to be passed when the signal is emitted. It's the fourth parameter (binds) in the documentation. For example, you could pass the player and/or the Area2D along with the signal, and the signal handler could use that information to figure out whether to do anything. https://docs.godotengine.org/en/stable/classes/class_object.html#class-object-method-connect

I have got it working in a different way than passing the player along with the signal as it didn't for some reason work. I did it by getting the body.get_instance_id parameter in the signal methods and comparing it to the instance id of the player that created it.
