Question by SmackDan · May 24, 2017 at 07:10 PM · rigidbody2dcollider2dedgephysics2d.raycast

Raycast(Physics2D) won't hit an Edge Collider unless I remove the attached Rigidbody2D

I recently updated from unity 5.6.0 to 5.6.1 and I have a feeling that's where the problem is located.

I have a couple of simple floating platforms using an edge collider. Unity takes care of all the collisions, but I use Raycasts from both bottom corners to check if the player is grounded. This works perfectly fine on every single level. However, on one of the levels I attached a Rigidbody2D to some of the floating platforms to make them move, fall or what not.

After upgrading to Unity 5.6.1, the Raycasts won't hit those colliders, unless I remove the Rigidbody2D component from the platforms. I did a quick test and this does not happen if I use a BoxCollider2D. Sadly, converting from Edge to Box colliders will break some of the features in my game.

I even tried to create a new empty object where I attached a Rigidbody2D, and placed the platform with a collider as a child, this did not work.

I'm wondering, is this an intended Unity function, or is this a bug?
Anyone know of some kind of work around?
