What is physics Raycast?
Raycast in Unity is a Physics function that projects a Ray into the scene, returning a boolean value if a target was successfully hit. When this happens, information about the hit, such as the distance, position or a reference to the object's Transform, can be stored in a Raycast Hit variable for further use.

Does raycast detect collisions?
Notes: Raycasts will not detect Colliders for which the Raycast origin is inside the Collider. In all these examples FixedUpdate is used rather than Update. Please see Order of Execution for Event Functions to understand the difference between Update and FixedUpdate, and to see how they relate to physics queries.
