Question
Hello,
I’m trying to get a stick (a RigidBody2D) to hang down from a ceiling (a StaticBody2D) using a PinJoint2D, but it always seems to be attracted to the right instead – just as if gravity was working to the right. I triple-checked and gravity is set to the positive y direction, and other unattached RigidBodies do fall down as expected.
I didn’t add any forces or motors in this project.
Why does my stick want to go to the right?
Here’s my node.tscn (this forum doesn’t allow me to upload text or zip files):

and project.godot (I don’t think I changed anything in it):
