Why does the Sprite2D become invisible when parent monitoring is set to false!?

Question

I have a Ship which has this child:

$ShipBody (Area2D)

$ShipBody in turn has 2 children:

$Sprite2D and $CollisionPolygon2D

The ship won’t be removed until 2 seconds after current_health <= 0 …

During those 2 seconds, the ship should no longer monitor collisions .

But, in each of these ways that I’ve tried, the $ShipBody/Sprite2D (or perhaps the whole ShipBody node) becomes invisible.

This is quite unexpected.
I’ve worked around this by putting the collisionpolygon into it’s own Area2D and make the Ship a Node2D instead. But I still think it should work the other way since collisions and visibility should be independent. So…
Why does it happen?

I tried this:

func take_damage():
  if current_health <= 0:
    $ShipBody.monitoring = false
    tween.tween_property($ShipBody, "modulate", Color(4, 2, 1), 2)

I also tried this:

$ShipBody/CollisionPolygon2D.set_disabled(true)

And this:

$ShipBody/CollisionPolygon2D.set_deferred("disabled", true)

you can disable the

$CollisionPolygon2D

Yeah I did that first and the exact same thing happened.
I’ve updated the post with that detail too.

I just read your thread again, can you set the sprite as a child of the ship instead of the Area2D

[TimothyAlexisVass]

The Sprite2D needs to rotate with the ShipBody. There are other parts that need to remain their orientation rotate but are part of the ship.

[pham150603]

How about setting the ShipBody as a Node2D and creating another Area2D as a child of the ShipBody

[TimothyAlexisVass]

That works and solves the How. Thank you!

However, I still think that is unexpected. Collisions and visibility should be unrelated as far as I understand it.

As far as I know, every time a node asks for something (the triangle yellow symbol with the “!” icon) the things it asks for become part of the node
