Error cs0246 unity3d как исправить

I’m trying to make a simple game using unity and C# with vs code. But when I try to build and run the program; it shows «error CS0246: The type or namespace name
‘UnityEngine’ could not be found (are you missing a using directive or an assembly reference?)»

and

» error CS0246: The type or namespace nam
e ‘MonoBehaviour’ could not be found (are you missing a using directive or an assembly reference?)»

I tried to fix the error «preferences -> External tools -> External script editors -> vs code»
but its not work.

But c# works in the random program correctly. When I run any unity scripts; its show error.

code sample in the below:

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

public class test : MonoBehaviour
{
    public string ab = "sh";
    // Start is called before the first frame update
    void Start()
    {
        
        
    }

    // Update is called once per frame
    void Update()
    {
        Debug.Log(ab);
        
    }
}

Всем привет, дамы и господа! Скопировал я значит код для сохранения данных с одного источника.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;

public static class SaveLoad 
{

    public static List<Game> savedGames = new List<Game>();

    //методы загрузки и сохранения статические, поэтому их можно вызвать откуда угодно
    public static void Save() 
    {
        SaveLoad.savedGames.Add(Game.current);
        BinaryFormatter bf = new BinaryFormatter();
        //Application.persistentDataPath это строка; выведите ее в логах и вы увидите расположение файла сохранений
        FileStream file = File.Create (Application.persistentDataPath + "/savedGames.gd");
        bf.Serialize(file, SaveLoad.savedGames);
        file.Close();
    }

    public static void Load() 
    {
        if(File.Exists(Application.persistentDataPath + "/savedGames.gd")) {
            BinaryFormatter bf = new BinaryFormatter();
            FileStream file = File.Open(Application.persistentDataPath + "/savedGames.gd", FileMode.Open);
            SaveLoad.savedGames = (List<Game>)bf.Deserialize(file);
            file.Close();
        }
    }
}

Мне выдало ошибку
(10,24): error CS0246: The type or namespace name ‘Game’ could not be found (are you missing a using directive or an assembly reference?)

Честно, я вообще не понимаю сути. Сможете помочь?

Trabla Description:

1. Simple project


2. Script «MyBuildScript.cs» to add custom menu to Unity3d Editor
— compile project for Androdi or iOS

Located in Assets folder

3. Source code of  «MyBuildScript.cs» script:

using UnityEngine;

using System.Collections;

using System.Collections.Generic;

using UnityEditor;

class MyBuildScript

{

static string[] SCENES = FindEnabledEditorScenes();

static string APP_NAME = «Demo»;

static string TARGET_DIR = «C:\Users\Public\Documents\Unity Projects\demo-buildScript»;

[MenuItem(«Custom/CI/Build Mac OS X»)]  // Creates menu item in unity editor

public static void PerformMacOSXBuild()

{

string target_dir = APP_NAME + «.app»;

GenericBuild(SCENES, TARGET_DIR + «/» + target_dir, BuildTarget.StandaloneOSXIntel, BuildOptions.None);

}

[MenuItem(«Custom/CI/Build Android»)]   // Creates menu item in unity editor

public static void PerformAndroidBuild()

{

string target_dir = APP_NAME + «.apk»;

GenericBuild(SCENES, TARGET_DIR + «/» + target_dir, BuildTarget.Android, BuildOptions.None);

}

private static string[] FindEnabledEditorScenes()

{

List<string> EditorScenes = new List<string>();

foreach (EditorBuildSettingsScene scene in EditorBuildSettings.scenes)

{

if (!scene.enabled) continue;

EditorScenes.Add(scene.path);

}

return EditorScenes.ToArray();

}

static void GenericBuild(string[] scenes, string target_dir, BuildTarget build_target, BuildOptions build_options)

{

EditorUserBuildSettings.SwitchActiveBuildTarget(build_target);

string res = BuildPipeline.BuildPlayer(scenes, target_dir, build_target, build_options);

if (res.Length > 0)

{

throw new System.Exception(«BuildPlayer failure: » + res);

}

}

}

4. Try to run build script from Editor  — menu «Custom» -> «CI» -> «Build Android»

5. Exception:

Assets/MyBuildScript.cs(4,7): error CS0246: The type or namespace name `UnityEditor’ could not be found. Are you missing a using directive or an assembly reference?

Solving:


1. Create folder «Editor» in «Assets» folder

2. Move script «MyBuildScript.cs» to «Assets» -> «Editor» folder

All scripts with using UnityEditor; should be placed in «Assets» -> «Editor» folder

I have SpatialAnchorConfig.cs at the path srcSpectatorView.UnityAssetsSpatialAlignment.ASAAzureSpatialAnchors.SDKScripts
