Class not accepted?

Unity Engine
1

I have tried to write an easliy script for my first time in Visual Studio. But when i tried to write it Visual Studio don´t accepted the class. I hope someone here can help me with that problem (and I also hope my english is good enough because I´m a german and I´m already learning english XD). Here is the code that I want to write:

Debug.Log(“Hello World”);

Thanks in advance

The above line of code is totally valid, but you can’t just write that alone. It must be inside an appropriate MonoBehaviour-derived class.

If you don’t know how to do that, scroll down for some good coding tutorials to get you started.

If you are just getting errors from Visual Studio, this may help you with intellisense and possibly other Visual Studio integration problems:

Sometimes the fix is as simple as doing Assets → Open C# Project from Unity. Other times it requires more.

Also, try update the VSCode package inside of Unity: Window → Package Manager → Search for Visual Studio Code Editor → Press the Update button

Also, this: No suggestions in Vscode

These are some good initial coding tutorials:

Imphenzia / imphenzia - super-basic Unity tutorial:

Here is the full code and I can see any mistakes:

sing System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class HelloWorld : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
Debug.log(“Hello World”);
}

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

}
}

Sorry I have deleted the u in the beginning of the code

Oh sorry for interruption I yet it works Im really sorry

For this we have the nice “Edit” button, no need to post multiple times.

also while posting code on the forum you want to use code tags.

You’ll get this:

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

public class HelloWorld : MonoBehaviour
{
    void Start()
    {
        Debug.log("Hello World");
    }

    void Update()
    {

    }
}

And as you seem to have figured out, that script should compile without a problem

Your first post does NOT match your full code post. You have a simple fatfinger typo.

If you elect to monkey-hammer-bang tutorial code in, you cannot make ANY typos in programming, otherwise you waste everybody’s time, including your own.

How to do tutorials properly:

Tutorials are a GREAT idea. Tutorials should be used this way:

Step 1. Follow the tutorial and do every single step of the tutorial 100% precisely the way it is shown. Even the slightest deviation (even a single character!) generally ends in disaster. That’s how software engineering works. Every single letter must be spelled, capitalized, punctuated and spaced (or not spaced) properly. Fortunately this is the easiest part to get right.

Be a robot. Don’t make any mistakes. BE PERFECT IN EVERYTHING YOU DO HERE.

If you get any errors, learn how to read the error code and fix it. Google is your friend here. Do NOT continue until you fix the error. The error will probably be somewhere near the parenthesis numbers (line and character position) in the file. It is almost CERTAINLY your typo causing the error, so look again and fix it.

Step 2. Go back and work through every part of the tutorial again, and this time explain it to your doggie. See how I am doing that in my avatar picture? If you have no dog, explain it to your house plant. If you are unable to explain any part of it, STOP. DO NOT PROCEED. Now go learn how that part works. Read the documentation on the functions involved. Go back to the tutorial and try to figure out WHY they did that. This is the part that takes a LOT of time when you are new. It might take days or weeks to work through a single 5-minute tutorial. Stick with it. You will learn.

Step 2 is the part everybody seems to miss. Without Step 2 you are simply a code-typing monkey and outside of the specific tutorial you did, you will be completely lost.

Of course, all this presupposes no errors in the tutorial. For certain tutorial makers (like Unity, Brackeys, Imphenzia, Sebastian Lague) this is usually the case. For some other less-well-known content creators, this is less true. Read the comments on the video: did anyone have issues like you did? If there’s an error, you will NEVER be the first guy to find it.

Beyond that, Step 3, 4, 5 and 6 become easy because you already understand!
