Rays and tags help?

Question

Here's my code for a raycast. I need help.

using UnityEngine;

using System.Collections;

public class RaycastScript : MonoBehaviour {

RaycastHit hit;

// Use this for initialization void Start () {

}

// Update is called once per frame void Update () {

if(Input.GetButtonDown("Fire1")) {

Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * 10000, Color.blue);

if (Physics.Raycast (transform.position, transform.TransformDirection(Vector3.forward), 100000000)) {

Debug.Log ("you hit something");

} }

I want to make it so that if the ray hits an object with the "Cube" tag, it sends a message to the debug.log that says "you hit a cube". Would I do:

if (hit.collider.gameobject.tag == "Cube") { debug.log("you hit a cube"); }

Or something else?

I use C#, btw

your current ray is using the method overload for (origin, direction, distance). If you want to return data about a tag you need to use a method overload that contains 'out hitinfo'.

For example:

 using UnityEngine;
 using System.Collections;
 
 public class example : MonoBehaviour {
     void Update() {
         RaycastHit hit;
         if (Physics.Raycast(transform.position, -Vector3.up, out hit))
             float distanceToGround = hit.distance;
         
     }
 }

With this data, you could then use your if statement to determine if the object contained the tag you need.
