Raycast retuning info of hit object

Question

Hi guys, I believe this is a very simplistic question, but I havent managed to find an answer to this one (at least one that I would understand).

My code:

   bool bIsButtonDown = Input.GetButton("Fire1");
             if (bIsButtonDown)
             {
                 Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
                 RaycastHit rch;// = new RaycastHit();
                 
             }

After hitting an object I would like to get info (tag, or more prefferably name) of the object. My goal is very simple - three boxes in the scene, and I want something to happen when one of them is hit. After getting info it is probably just a simple "switch" but I can`t seem to understand how to get that info.

Being a noob, it will help me even if you can at least point me in the right direction. :)

To do a raycast you can use Physics.Raycast() method:

 bool bIsButtonDown = Input.GetButton("Fire1");
 if (bIsButtonDown)
 {
     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
     RaycastHit rch;

     if(Physics.Raycast(ray, out rch))
     {
        // do something
        // rch variable contains all the info about the object that is hit
     }
 }

Thank you! I didn`t know that, now it works like a charm! :) In case anyone else needs the same thing I just used this line:

name = rch.collider.name; Debug.Log(name);

Is there a way of only doing something if the raycast hits a specific object? If so, how do you confirm that the object was hit by the ray:

 if(Physics.Raycast(ray, out rch))
 {
     if(*ray hits specific object*)
     {
         // do something
     }
 }

I know this question was asked two years ago and that this is a long shot but hey! :P

@Gerflukon lol almost exactly a year later :P Use RaycastHit.transform.gameObject, as per this page:
