How to make RayCast from an object in a unit?

Question

Unity

Hello! I'm creating a game, I need to make the enemy see the player. For this I chose Raycast. I can't make the ray shoot from an object (public GameObject posToRay). How to do it so that the script is on one object and the beam comes out of the posToRay object. Thanks in advance! If necessary, I will describe more clearly.

Answer 1

The ray comes out from any coordinates you specify. Though this object, though another, even the "center of the universe."
Physics.Raycast(posToRay.transform.position, ...)
