Put it inside a KinematicBody2D and set the pickable flag on the KinematicBody2D.

Area2D doesn’t work? And what’s a pickable flag?

Not sure what you mean by Area2D, don’t know where that came from.

The general approach is to create a KinematicBody2D as a container for the whole “clickable” thing, add a CollisionShape2D to that, and set the shape, then add a script to the KinematicBody2D to react to the clicks, and set the pickable flag on the KinematicBod2D in the Inspector. It should look something like this in the Scene panel:


And if you click the KinematicBody2D and look in the Inspector panel, there is a section called “Pickable”, unfold that and there is a checkbox in there called “Pickable”, enable that and it should respond to mouse clicks through the _input(event) function on your GDScript.

Note: Sorry, this site doesn’t support attachments, otherwise I’d attach a screengrab to show it better. Hope this helps.

That’s help a lot, thxs as much! It would work with a collisionpolygon2D also, cause I have to set a circle for my clickable zone?

Should work with either CollisionShape2D, for which you can assign a variety of different basic shapes, or CollisionPolygon2D which you can define arbitrarily.
