I have a scene with instances of two other scenes I've made inside of it, my player and a building. The player is built off of a KinematicBody2D, and the building has an Area2D as a child whose shape is a LineShape2D. The player's shape in no way overlaps with this LineShape2D, but when I run the scene, the Are2D detects that the player as entered it. I'm not sure what I'm missing here.
Edit: I modified the building scene so that the Area2D begins with monitoring set to false, and then after 5 seconds monitoring is enabled. Sure enough, after 5 seconds were up, the Area2D registered every body in the scene having entered it, even though none of them did. Is this just some weird property of LineShape2D? Because its behavior otherwise is exactly what I need, but I don't know how to avoid this beyond I guess just ignoring bodies that enter it for a split second after the scene runs, and I feel like there should be a more graceful solution.
