I have a question:
Typically, a node will be removed from the view of its position if it exceeds the device's height.
I'm using gravity so it falls back down into the view. How would I make it so the node doesn't remove itself from the view?
A node does not remove itself from the view once it goes off screen. It's still there but no longer gets rendered. If it has a physics body, physics calculations are still ongoing despite being off screen.
The only instance a node gets removed is if you remove it from parent.
