Hello guys!

I have a base Scene “Enemy” with Area2D “detect_radius”.
In script i do:

export (int) var detect_radius
func _Ready():
$DetectRadius/CollisionShape2D.shape.radius = detect_radius

I inherit from this Scene and Change the value of the Export var.
Enemy to 30.
Endboss to 50.

Now to the Problem… in my tree if i put it like this.

-Enemy
-Endboss
Both of them has 50.

Otherway around.
-Endboss
-Enemy
Both of them has 30.

Do i understand something wrong?
Or do i Need the Area2D in every Scene and not inherit from Enemy?

The problem is that they are sharing the same collision shape.
To fix this you would have to do something like this:

export (int) var detect_radius

func _ready():
    var circle = CircleShape2D.new()
    $DetectRadius/CollisionShape2D.shape = circle
    $DetectRadius/CollisionShape2D.shape.radius = detect_radius
