Hey, so im making something and i have a problem that i actually can't explain or describe.
So im pretty sure most of you know the 'Physics.RayCast' thing from unity, but for some reason that doesn't work for me, yes i am using the UnityEngine namespace, and from videos  showing how to use that they don't seem to have any problem whatsoever and they are only using the namespace UnityEngine so i really have no clue what the problem could be, anyone has any idea?

Those videos are most likely very outdated, using older versions of Unity. For Rust, you'd need to reference specific modules, as the DLLs were split.

Yea figured that out
