    I'm having a really weird issue with my 2D collider on a moving image. When the player moves their head, the trigger moves away from the image it's attached to. Here's my code for making the image move.

    Code (CSharp):
    1. secondHandTransform.eulerAngles = new Vector3(secondHandTransform.eulerAngles.x, secondHandTransform.eulerAngles.y, -timePassed * 12f);
    The canvas's render mode is Screen Space - Camera which is important for some other stuff I have so I can't change that. I have tried putting the collider on a child object, but that doesn't work. I've tried removing the rigidbody, but that doesn't work either. Thoughts?

    Why are you trying to rotated something that exists in the 2D XY plane in 3D XYZ space? This just won't work. If you want that then use 3D physics.

    There really isn't enough information about to know what is actually going on though.

    If you find yourself reaching for transform.eulerAngles and reading data back from that, that's a "tell" for you to stop and rethink your strategy.
