How to tell when object moves out of camera boundary/view

I have two players. Camera is attached to player 1. When player 2 goes out of camera view I want to print(“out of bounds”). It’s a 2D game with camera2d node.

How should I go about doing that?

Have you tried checking the root Viewport’s boundaries against the second player’s position? For example:

# Do this check when the second player moves.
if player2.position > get_tree().get_root().size:
    print("Player 2 is out of bounds.")

I don’t know whether this will work, but it’s a start.

Thank you! But what if camera is zoomed out. I guess I will have to do some adjustments.

Hi, you might find this tutorial from Kids Can Code helpful: Entering/exiting the screen.

Specifically the part about VisibilityNotifier2D.

Good luck!

Thank you! I will try this.
