Question Problem on a 3d tutorial

Excuse my english but i'm using googletranslate.
I'm studying tutorials but I have a big problem with a script that serves to get information about an object watched by the character. link

In practice, once the script has been inserted, the Interaction_Info_UI option should appear in the inspector window as in the video, but it does not appear (https://image.forumfree.it/1/3/9/4/9/5/8/7/1677847535.jpg) .
I've posted the script, if anyone could help me:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class SelectionManager : MonoBehaviour
{

public GameObject interaction_Info_UI;
Text interaction_text;
private void Start()
{
interaction_text = interaction_Info_UI.GetComponent<text>();
}
void Update()
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast(ray, out hit))
{
var selectionTransform = hit.transform;
if (selectionTransform.GetComponent<interactableobject>())
{
interaction_text.text = selectionTransform.GetComponent<interactableobject>().GetItemName();
interaction_Info_UI.SetActive(true);
}
else
{
interaction_Info_UI.SetActive(false);
}
}
}
}

 

Go to "Code" in the WYSIWYG editor and insert your code to format it.

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.UI;
6. public class SelectionManager: MonoBehaviour {
7.   public GameObject interaction_Info_UI;
8.   Text interaction_text;
9.   private void Start() {
10.     interaction_text = interaction_Info_UI.GetComponent < text > ();
11.   }
12.   void Update() {
13.     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
14.     RaycastHit hit;
15.     if (Physics.Raycast(ray, out hit)) {
16.       var selectionTransform = hit.transform;
17.       if (selectionTransform.GetComponent < interactableobject > ()) {
18.         interaction_text.text = selectionTransform.GetComponent < interactableobject > ().GetItemName();
19.         interaction_Info_UI.SetActive(true);
20.       } else {
21.         interaction_Info_UI.SetActive(false);
22.       }
23.     }
24.   }
25. }
26.  

The url you posted shows this:

---------------------

And, the script you've given will not compile. So it is hard to say what the problem is with it. For example "interaction_text = interaction_Info_UI.GetComponent < text > ();" where "< text >" must be "< Text >" to compile.

There are other issues like that, which I assume happened when copying the code at some point. But most likely that variable is not appearing in the editor because your code is not compiling. Look at the Console window, and find the errors listed (if any).

 

I change site to post images:
here are screenshots of the tutorial (on youtube from minute 2:50 to 9 "

here are my problems

I don't know where I go wrong, I think I did exactly what the tutorial says

 

So that is the problem. InteractableObject.cs doesn't exist. You need to create it. or the class name in that file doesn't match "InteractableObject".

 

I understand....but this is how it works for him in the tutorial, the script is written the same and the objects have the name he wrote. Did he omit any steps?

 

He had already created that script, but didn't show it being done in the video.
Look at the whole video. At around the 14min time he shows the contents of the InteractableObject script, so you should be able to create the script from what he shows.

 

... seen now.... is that it should be a step by step tutorial and I didn't imagine that things would be explained later -.-' Thank you

 

It seems you are very new to programming. I recommend starting with a tutorial on the basics of programming. Before you start making a game, you should be able to see errors in the console, and understand what this particular error means. If you understand the basics on debugging and syntax, I think you will have a better time following this and other tutorials. As it stands, needing to come to the forum for this particular issue is a sign that you need to learn more about the basics of programming - because this is one of the simplest and easiest errors you will encounter.

(I don't mean that in an insulting way. We all start from the beginning, and I just want to direct you down a path that will be less frustrating for you/be a better starting experience.)

 

I can't blame you, I actually studied c++ (standard programming), I thought I could understand c# by unity, but I think it will be difficult to understand

 

You'll find it is definitely different, but I suspect that after you get over the initial hurdles and confusion of the changes, you might find it is far easier. The syntax, in my opinion, is much more human readable. And you don't have to ever worry about garbage collection. I found C# to be 100x easier than C++.
