Random beginner-question #3: Touch Input only on Area2D

Hi everyone,

the issue is: tapping on a touch-screen is being registered anywhere, but not only on the object I’d like to.
So if I had an Area2D (with a CollisionShape attached) in my scene, would there be a simple way of having taps registered only in this area (and not on the “rest of the screen”)?

Any suggestions?

Add a touch screen input as a child. Add a shape to it and and make it the size of the Area2D.

I had the same idea earlier, but couldn’t quite figure out how to make it work. The scene is set up like this:

Node2D     # the script is attached here
|-- Area2D
    |-- CollisionShape2D
    |-- (and a sprite here)

And my simple script is:

extends Node2D

func _input(event):
	if event is InputEventMouseButton:
		if event.is_action_pressed("mousebuttonclick"):
		if event.is_action_released("mousebuttonclick"):

Where would you suggest inserting the child (and which one would be best suited for a touch screen input?)

Thanks for your help!

You can make it a child of Area2D. You can add a shape or an image to get the size to match the size of the Area2D.
Add signals for pressed and release, you don’t need the _input event.
