설명

Cast a 3D ray against the 2D Colliders in the Scene.

This function acts as a 3D "ray cast" but specifically designed to detect 2D Colliders. It achieved this by projecting the 3D ray into 2D space and then performs the 2D intersection test, ordering the results by the Z direction of the original 3D ray.
